The warm atmosphere, strong emotions, and the power of inheritance began in the summer of 1956. In the 55 years, it has been changing and has not changed. On July 15, 2011, FAW liberation ushered in the 55th anniversary of the release of the first auto liberation truck in New China. At the same time, the commemorative version of the liberation of the 100,000th J6 heavy truck and the 55th anniversary of the Liberation was delivered to the users on the same day.
As the liberation of the sixth-generation high-end products by FAW, the emergence of the Liberated J6 heavy truck is the best proof that FAW's liberation and repairing vehicle technology is synchronized with the world's leading technologies. After five years of careful tempering and three generations of development and integration, it is reliable, fuel-efficient, safe, lightweight, and comfortable. The liberation of the J6 high-end heavy truck is also a milestone product that won the 2010 National Science and Technology Progress Award. It is the first time that the national automobile industry has won this award since the founding of the country. It has witnessed the high-speed leap of FAW's liberation of science and technology and laid a foundation for liberation. The brand's leading position in the world heavy truck market.
In the evening, a grand and warm theme party was held in Changchun. The theme of this evening was the liberation of the 55th anniversary. • In an extraordinary tradition, the participants included outstanding inheritors who were selected from millions of emancipated users nationwide for two months.
They are 55 individuals, they represent 55 families or businesses, they have 55 dreams and pride, their development is large or small, they follow the footsteps, either long or short, but their entrepreneurial stories and their inspirational spirit It is exactly the same as the emancipatory truck that was the eldest of the national cars. Everyone was commenting on the emancipation of the soul and the carrier and witnesses of the history of the liberation. This is the extraordinary salute of the four most remarkable legacy of the evening.
Extraordinary Heritage Loyalty Award, Extraordinary Heritage Expert Award, Extraordinary Heritage Innovation Award, Extraordinary Heritage Touching Award, here, it has already surpassed the awards and awards themselves, those from the most basic user voice, the most unadorned and firmest words, the most persistent The most progressive belief is flowing, flowing and warming among all the inherited users. It is the liberation of 55 years of emotional integration. It is the voice of liberating the past, present and future.
He is one of the first users of the country to rely on liberation vehicles to get rich. His Qingxian County is also the country’s first liberation county.

They are a pair of brothers and they are a successor. They came from the villagers of Yiyang County, Luoyang City. They once faced the loess and turned to the sky. It was the liberation car that changed the situation of this family and the situation of this generation. In 2004, Now, for 7 years, like brotherhood, the complexes of liberation cars generally condense. They have enriched themselves and still not forget their fellow villagers. The entire village and nearly 100 liberation vehicles have achieved a legend. They are Yang Shujie and Yang Shuqiang, winners of the extraordinary innovation award.
He is an old man in his 70s. He is the patriarch of a four-generation family. From children to grandchildren and even great-grandchildren, each is associated with the liberation car. Each is a user of the liberation car. The old man Li Xinglin believes: The firm support and loyalty and faith from national brands will surely pass on from generation to generation! He is Li Xinglin, the winner of the extraordinary passing and touching award.
The 55th Anniversary of Liberation • Extraordinary Heritage Festival, from historical remembrance, to practical innovation, to glorious inheritance, multiple layers of simultaneous interpretation of the liberation of FAW liberation, and finally condense into one sentence: 55 years, thanksgiving walked together, thanksgiving together before Row.
At the end of the evening, a grand ceremony to subvert the awards ceremony was held quietly. The Extraordinary Heritage Contribution Award is awarded to four emancipated employees for their honor. They are the developers of two men and women apprentices and two generations of liberation cars. They dedicated their youth and enthusiasm to liberation, relaying their inspirational and enduring succession. They are The liberation paid and received praise from all users of the terminal. When a share of pay has paid off, when users of Jiefang Truck award trophies for this obscure contributor for decades, this kind of user-level word of mouth recognition is the liberation of continuous improvement, continuous improvement, continuous glory and perpetual power. .
The scene of the evening party was warmly and eloquently performed in such a peaceful and progressive manner. The original singer Liu Bingyi of the “Old Driver†and the contemporary artist Cheng Wei, who only insisted on liberating cars for more than 20 years, came to the scene and acted as The awarding guests honored liberation users who inherited their dreams and witnessed their glory. The migrant workers' hip-hop dance team who won the “China Talent Show†championship also exhibited their skills in the liberation of work clothes. These represent the image of the new generation of workers and represent achievements. The spiritual power of the dreams/beyond dreams was infinitely enlarged and moved in the evening.
The whole party was greeted with a joyful atmosphere, permeated with spiritual inheritance everywhere, filled with the warmth of home, let all arriving users feel an unforgettable spiritual inspiration, it is to follow the new China's first auto liberation truck, sustainable The power of transformation and unlimited hope, when a moving power, a power of trust, and a power of inheritance converge, we believe that liberation will work with users across the country to create a brighter future.
Tungsten carbide roller has characteristics of good wear resistance, high temperature red hardness, thermal fatigue resistance and thermal conductivity and high strength , have been widely used in high-speed wire rod, bar, rebar, seamless steel tubes, etc. Domestic production of tungsten carbide roller materials mostly WC- Co, WC- Co- Ni- Cr two series, and the content of Co, Co- Ni - Cr is in the range of 6wt% ~ 30wt%. From the use of perspective, tungsten carbide rollers has good mechanical properties, its flexural strength up to 2200 MPa or more, shock toughness up (4 ~ 6) × 10^6 J/ m^2, Rockwell hardness (HRA) is up to 78 to 90, widely in the high-speed wire rod rolling process, which is much higher than single-slot chilled cast steel or high speed steel rolls.Tungsten carbide is made of Tungsten Carbide Powder and binder phase (such as drilling, nickel, etc.), and then pressing and sintering, regardless of the conditions under cold rolled or hot rolled has excellent wear resistance, tungsten carbide rollers has been widely used in pre-finishing mill and finishing of high-speed wire rod currently. On the performance of tungsten carbide roller in hot-rolling wire rod , the material must meet the following requirements:
1. Sufficient anti-fracture strength;
2. Good abrasion resistance;
3. The smooth surface finish;
4. Excellent corrosion resistance, thermal fatigue, thermal cracking performance.
Tungsten carbide roller rings can working in bad conditions , small profile rolling (especially rebar rolling) process conditions is harsher than the high-speed wire rod, and therefore corresponds to the profile rolling ,tungsten carbide rollers recommend using high binder phase carbide.
Tungsten carbide roller material design
Pre-finishing all vehicles roller should ensure its high toughness, strength, rigidity and thermal conductivity, followed before considering its wear resistance. When designing each vehicles roller, pre-finishing materials should choose carbide grades of Co, Co- Ni- Cr binder content is high (greater than or equal to 25wt%) , requiring an average WC grain size of coarse (5μm ~ 6μm), to obtain a higher shock toughness, proper strength and hardness. For the finishing of the roller movements, particularly the last two rollers of the finish rolling, which suffered load is small, and high relative velocity of the material to be pressed (80 m / min ~ 120 m / min). In this case, the wear resistance of the roller to be the most important requirements, and must ensure the strength , timpact toughness and hardness of a reasonable match, so the binder of Co / Ni content ratio and the average grain WC control of particle size and other factors must have greater control in front of different pre-finishing rolling roll.
Tungsten carbide roller category
According to the structure of tungsten carbide rollers, it can be divided into solid tungsten carbide roller and composite tungsten carbide roller. Solid tungsten carbide rollers have been widely used in pre-finishing and finishing stands high speed wire rod mill (including fixed reducing the rack, pinch roller rack). Composite tungsten carbide roller is made of cemented carbide and other materials, and it can be divided into tungsten carbide composite roll rings and solid tungsten carbide Composite Roller. Tungsten carbide composite roll rings mounted on the roller shaft; solid tungsten carbide composite roller will be directly cast in the roll axis to form a whole, a large load is applied to the rolling mill.
Tungsten carbide roller production process control
Tungsten carbide rollers produced by powder metallurgy method, the key to its process control is the chemical composition of the material and the mixture was prepared, pressed molding, sintering and deep processing and other preparation process parameters.
1. Preparation of starting material (WC focus quality): As the WC raw material and quality control of the use of different levels of quality may fluctuate, resulting in adverse effects on microstructure.
2. Preparation of the mixture: Mixture preparation is the key to the production process of the roller, the roller of failure modes - trachoma, mainly generated by this procedure.
3. Pressing: roller pressing is an important process of the roller mill.
4. Sintering: roller sintering is to determine the final quality of the roller production processes, use of advanced low-pressure sintering technology, HIP sintering technology can greatly improve the performance of roller.
5. Deep processing: deep processing rollers have a greater impact on the quality and accuracy of the roller surface.
