【Summary Description】The operation of this production line has doubled the production of Jianheng Industry and successfully entered the manufacturing industry of 100000 tons of cold-rolled stainless steel. Its excellent product quality will enhance Jianheng's market competitiveness and capture the hearts of more stainless steel users.
On the evening of August 5th, 2014, our company successfully conducted a one-time hot load test run of the complete set of cold rolled stainless steel continuous annealing and pickling unit contracted by Zhejiang Jianheng Industrial Co., Ltd! The trial production steel grade is SUS201. The production line can produce strip steel with specifications ranging from 0.25 to 2.0mm * 1000-1250mm, inlet and outlet speeds of 70m/min, and the fastest speed in the process section of the unit is 50m/min. After testing, the surface color, hardness, and other indicators of the produced stainless steel coil are superior to those of the same type of ordinary annealing production line.
The annealing furnace of this production line adopts a modular design, and the main control components of the equipment are all imported high-quality products; For austenitic stainless steel, a three-stage cooling method (first stage air cooling, second stage fog cooling, and third stage water cooling) has been successfully applied; Flexibly select the annealing treatment method of rapid cooling followed by slow cooling for solid solution requirements; The use of multi-level combustion control to minimize oxidation and burning losses; The entire equipment and system have high cost-effectiveness, and low engineering and maintenance costs.
The operation of this production line has doubled the production of Jianheng Industry and successfully entered the manufacturing industry of 100000 tons of cold-rolled stainless steel. Its excellent product quality will enhance Jianheng's market competitiveness and capture the hearts of more stainless steel users.
Thank you to Jianheng for the harmonious cooperation of all personnel involved in the installation and debugging project. During the debugging process of this project, our company's process leader Qian Wei thoroughly studied advanced production processes both domestically and internationally, and proposed many constructive opinions and plans; The person in charge of software debugging, Zhou Bo, demonstrated a high level of professionalism by fully communicating with the process leader and various equipment suppliers on site, fully considering the interlocking conditions of equipment safety, and taking the stability of the system to a new level.
At present, according to the verification by the Environmental Protection Department of Liaoning Province using GPS positioning, 67 of the 106 enterprises to be eliminated have been eliminated in Liaoyang County, and the remaining 39 enterprises will be eliminated by the end of this year.

Recently, an Israeli inventor launched a pocket infrared spectrometer called SCiO, which can be used to scan physical objects around and deconstruct their chemical components. It can not only test the composition of food, but also detect whether plants need to be watered, what kind of medicine the label is torn off, and even test the ingredients of gold, rubber, and leather. At the same time, it will quickly feed real-time information back to smartphones, which may greatly change the way people shop and improve the quality of healthy life in the future.More +
