Bearing steel test in process improvement

Bearing steel test 2020 - in process improvement 11 - 17 xingtai iron and steel, bearing steel limited liability company is the company's focus on high-end steel grade, as the company continued development of high-end customers, for high-end bearing steel inclusions and carbon segregation, mesh quality indicators continue to improve, steelmaking technology center continued to carry out the process test, to improve the quality of the product performance. Requirements for bearing steel company orders recently, steel mills by the early stage of the production plan, arrange to optimize the process test. Mainly for high-end bearing steel inclusion control links, for refining slagging process, RH furnace process, continuous casting machine protection casting and optimize the flow field and so on to conduct a comprehensive optimization control and improve the inclusion process control ability. Subsequent technical staff will further tracking product performance test evaluation, continuous optimization of process control, steadily improve product quality, improve the market competitiveness of the company's products. Steel cast steel across the liquid suspending crown adding zero voltage protection steel cast steel across 25 # is 90 t lift liquid crown crown, for metallurgical bridge crane, is a key equipment anterograde steel production. By checking the found recently, because of the cast steel across 25 # crown online earlier, the big car translational frequency institution, in the control circuit and unprotected disc contactor control of zero pressure protection circuits, the liquid crane crane safety threat, stable and reliable operation. , steel mills run workshop technical staff through new auxiliary contactor in crown electrical tank protection set point, new wiring to PLC central control, the control points connected to the PLC in the PLC program compiled big car body zero voltage protection control program, the program list into the big car inverter output control, a zero voltage protection function, reduce all kinds of accidents, in order to ensure the liquid hung crown translation agencies can safe, stable and reliable, work hard to achieve essential safety, to lay a solid foundation for steel safe production.
