Recently,Baosteel Special Material tool and die steel Cr12MoV achieves two furnace continuous casting and hot rolling plate forming.This marks that Baosteel Special Material had become the pioneer enterprise in the industry which master tool and die steel vertical continuous casting and hot rolling process and has bulk stable supply capacity.The product maximum width reaches 2600 mm,and fill the domestic gaps.Compared with currently widely used tool and die steel die casting and hot rolling process,vertical continuous casting and hot rolling process can not only increase production efficiency and quality ine production process,but also reduce heating times by half,reduce energy consumption and increase material forming rate by 15%,with significant cost advantage.
Due to high carbon content,tool and die steel is crack sensitive and is not fitful for general steel production continuous casting and hot rolling production process.Therefore,continuous casting and tool and die steel are considered to be irreconcilable opposites.For a long time,almost all the world's iron and steel enterprises adopt die-casting and hot rolling process in the production of this product.Cr12MoV product is highly representative in the tool and die steel varieties and is one of the highest carbon content product.Therefore,the successful adoption of vertical continuous casting and hot rolling process in this product production shows Baosteel Special Material's success in tool and die steel vertical continuous casting and hot rolling process exploration.
Tool and die steel is one of the main products of Baosteel Special Material alloy strip production line.As the country's first alloy strip production line,it includes steelmaking,continuous casting,and steckel hot rolling project and the project is put into operation in 2009.In 2010,Baosteel Special Material begins tool and die steel trial work.Tool and die steel market is a mature market,and in the current grim steel market situation,tool and die steel demand remains relatively stable.How to use its own technology and equipment advantage,enter the market and support the company's production and operation?Early last year,Baosteel Special Material joins with Baosteel Group Central Research Institute,Baosteel Co.,Ltd.steelmaking mill,hot rolling mill,manufacturing department,Baosteel Metal,Special Steel technical center and forms tool and die steel production,marketing and research team and makes efforts to promote the work.Production,sales and research team focuses on tool and die steel high-end market,creates the idea of bulk stable production by way of vertical continuous casting and hot rolling process,occupy market with low-cost advantage while filling the gaps in terms of product specifications.Under the strong support of Baosteel Group Central Research Institute process institute and Special Steel technology center,after eighteen trials,Cr12MoV production finally achieves breakthrough recently and product yield rate reaches above 90%.At present,Baosteel has formed a supply capacity of 2000 tons per month.
