Yu Quanxing, a researcher at China Shipbuilding Design and Research Institute Co., Ltd., pointed out that with the upgrading of China's shipbuilding industry product structure and the high-end ship products, shipbuilding enterprises have put forward higher requirements for the quality of ship pipelines. As an important part of digital shipbuilding, ship pipe processing must also take the road of integration of industrialization and informationization, and transform traditional pipe manufacturing workshops with information technology to realize modernization of pipe production. Accelerating the application of digital technology in ship pipeline processing is conducive to improving the quality and efficiency of pipeline processing, improving the integrity of intermediate products such as ship segmentation and unit assembly, and shortening the construction period of docks and docks.
Zhao Gang, deputy general manager of Dachuan Heavy Industry Co., Ltd., said that the process of “first welding and bending†of pipes is an advanced process for digital processing of pipe processing. The pipe “first weld and back bend†process must be developed to calculate the pipe without allowance and the flange assembly pre-rotation calculation program. There must be pipe length measurement, nesting procedure and length measuring equipment, fixed length cutting program and cutting equipment, pipe With the flange assembly, welding, bending procedures and corresponding equipment, and establish a data technology processing center, according to the relevant data to form information instructions, digital control, in order to semi-automatic or automated processing of the pipeline.
Shen Yahui, general manager of Tangshan Kaiyuan Automatic Welding Equipment Co., Ltd. said that the company has been working hard to improve the application level of digital technology in ship pipe processing workshops. According to reports, the company's flange welding production line has been in the shipbuilding industry, such as Dachuan Heavy Industry, Dalian COSCO Shipyard Engineering Co., Ltd., Dalian Zhongyuan Shipbuilding Industry Co., Ltd., Qingdao Beichuan Pipe Industry Co., Ltd., Singapore Keppel Shipyard, etc. Get the app.
It can be prepared by directly crushing natural calcite, limestone, chalk, shell, etc. by mechanical methods (using Raymond mill or other high-pressure mill). Because the sedimentation volume of heavy Calcium Carbonate is smaller than that of light calcium carbonate, it is called heavy calcium carbonate.
Heavy calcium carbonate is abbreviated as heavy calcium. It uses high-quality limestone as raw material and is processed into white powder by a lime mill. Its main component is CaCO3. Heavy calcium has the characteristics of high whiteness, good purity, soft hue and stable chemical composition. Heavy calcium is usually used as a filler. It is widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. Increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of the rubber, improve the processability of the rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of the rubber.
