Pressure vessel trial vacuum rolling stainless steel composite plate
It is understood that in the past, domestic pressure vessels used stainless steel clad plates with explosive methods, and vacuum-rolled stainless steel clad plates for pressure vessels have not been used in pressure vessels since they were not mass-produced and reviewed by experts. At present, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China has approved and approved the trial of vacuum-rolled stainless steel composite plates in the pressure vessel industry.
Tianzun Company combined Sangang Group's mid-plate rolling technology, innovatively developed a vacuum rolling compounding process that can be used in industrial production, and established a 40,000-ton stainless steel composite material production line in phases. The first-phase 10,000-ton/year production line has been completed and put into production. . The company's stainless steel composite steel plate has three types: double-sided composite stainless steel composite panels, single-sided composite stainless steel composite panels, high and low grade stainless steel composite panels.
According to Tianzun's technical personnel, the vacuum rolling method has four major advantages: First, the technological advantages. Full use of mechanical automation flow operation, can achieve large-scale mass production. The second is the performance advantage. The hardware of the production line adopts EMS informationized process control. The software is controlled according to the quality management system, and the product performance is stable. The third is the specification advantage. In the rolling process, flexible mid-plate widening rolling process can be adopted, which breaks through the limitation of raw material size. Fourth, price advantage. Mass production reduces the flat-rate costs, and the price can be reduced by 20% to 70% compared with the same specification stainless steel.
More than 200 representatives of machinery manufacturing and pressure vessel manufacturers in Jiangsu Province attended the meeting. Shou Binan, chief engineer of the China Special Equipment Research Institute, was invited to attend the meeting and gave a preview of the new technology of vacuum rolling. The following picture shows the conference site.
stone carving emphasizes realistic modeling, mellow and delicate techniques, and smooth and free patterns. Its traditional skills began in the Han Dynasty, matured in the Wei and Jin Dynasties, and became popular in the Tang Dynasty. Stone carvings have a long history. They pay attention to lifelike shapes, round and delicate techniques, and smooth and free patterns. Carving products mainly include figures, animals, fireplaces, flower pots, balustrades, fountains, reliefs, dragon pavilions, dragon columns, jade pavilions, birds and animals, and various fine sculptures. It has both the charm of ancient art and the elegant and fast modern art style. It enjoys the reputation of "outstanding craftsmanship" and "earth shattering" at home and abroad.
