Application of analytical iron bars
Application of analytical iron bars
The horizontal continuous casting process can be obtained relatively dense matrix structure,the level of continuous casting profiles Hydraulic resistance and air tightness were higher than other engineering materials,we can say,with a horizontal continuous casting sections of steel production is by far the best hydraulic material.In addition to its high-yield,low production cost,there are significantly superior than steel machinability,it is because in the cutting process,the cutting continuous fragmentation,and reducing the cutting resistance.

Characteristics of gray cast iron, classification and application
Characteristics of gray cast iron, classification and application
Common gray cast iron due to the presence of graphite,and graphite tensile strength is almost zero,can be cast as full of cracks or hollow steel.Not only undermine the continuity of the graphite matrix,reducing the load-bearing metal matrix effective cross-sectional area,so that the actual stress is greatly increased;at the same time,the graphite is easy to cause stress concentration at sharp corners,sharp corners of the stress is much larger than the average stress.

Strip casting technology to subvert the traditional iron and steel manufacturing model
Science and Technology Daily News(Reporter Wang Jin Wanxia)steel outbound,rapid solidification,the casting and rolling into one,the whole process at one go.Originally up to nearly 1000 meters sheet production line is"concentrated"into the 50 meters,casting molten steel into steel just 25 seconds.In October 21-23 held its sixth Baosteel Biennial Academic Conference"steel near net shape casting"technology branch of the court,the reporter was informed that Baosteel's independent integration of strip casting technology has been successfully put into trial operation stage of production,and good performance.Baosteel has become after the United States Nucor,Germany Thyssen,Nippon Steel and South Korea's POSCO fifth country to master the technology of steel companies,and the international advanced level.

Development of China's steel industry strongly support the rapid rise of the national economy,but with the resources,the environment and the transformation of economic development model is facing from quantitative to qualitative change of great challenges.Wherein the large cross section of high-quality special steel products have long been used ingot plus forging process,longs low processing costs and high energy consumption,low production capacity and that this process can not meet the needs of the development of related industries,which restricts clean energy,development of nuclear power,marine engineering as well as high-speed railways and other high-end manufacturing.The level of development of high-quality steel obedience"multiplication rule",in which metallurgical equipment technology and production technology is the biggest factor in weight.
