On the evening of August 5, 2014, the one-time hot load test run of the complete set of cold-rolled stainless steel continuous annealing and pickling unit contracted by our company in Zhejiang Jianheng Industrial Co. The trial production steel is SUS201, the strip size of this production line is 0.25-2.0mm*1000-1250mm, the inlet and outlet speed is 70m/min, the fastest speed of the process section of the unit is 50m/min. after testing, the production of stainless steel coil surface color, hardness and other indicators are better than the same type of ordinary annealing production line.
　　The production line annealing furnace with modular design, the main control components of equipment are imported high-quality products; for austenitic stainless steel, the successful application of the three-stage cooling (the first level of air-cooled, the second level of mist-cooled, the third level of water-cooled); for solid solution requirements, the flexibility to choose the first emergency cold after the slow cold annealing treatment; multi-stage combustion control is used to minimize oxidation burn loss; the whole equipment and system cost-effective, low engineering and maintenance costs.
　　The production line put into use, so that the output of Jianheng Industrial doubled, successfully entered the 100,000 tons of cold-rolled stainless steel manufacturing big business. Its excellent product quality will enhance market competitiveness and capture the hearts of more stainless steel users for Jihaneng.
　　Thank you for the friendly cooperation of all the personnel involved in the installation and commissioning project of Jianheng. During the commissioning of the project, Qian Wei, the person in charge of our process, fully studied the advanced production process at home and abroad and put forward many constructive suggestions and solutions; Zhou Bo, the person in charge of software debugging, showed a high degree of professionalism, fully communicated with the person in charge of the process and various equipment suppliers at the site, fully considered the interlocking conditions of equipment safety, and raised the stability of the system to a new level.
