Seamless calcium cored wire for what steel mills
With the rapid development of science and technology, China has become a world power in the field of smelting. Meanwhile, the rapid development of science and technology has also made the smelting field more and more efficient and the production quality better and better. The use of seamless calcium lines in those steel mills is very high. Seamless pure calcium cored wire plays a very important role in our steelmaking and cast iron. Due to its great flexibility, we can make different seamless pure calcium cored wire according to different alloys. In the production of cast iron, with seamless pure calcium cored wire for hot metal desulfurization, spheroidization and inoculation of the foundry continued to add, expanding faster and faster. Use seamless pure calcium in the earliest development package produce ductile iron core skills of Germany as an example, the end of 1989, Germany countries as long as a foundry with seamless pure calcium packet core method to produce ductile iron, and by 2002, there are 56 factories (about 32% of its ball iron works) in a seamless pure calcium core skills instead of the original insertion method, pressure plus magnesium method, etc. It is the policy that steel mills and founters all over the world always seek to produce high quality products at low cost. The practice including our country has proved that the cored wire skill is one of the easiest and most agile and efficient skill methods to end this wish in many aspects of molten steel and molten iron treatment in the world today. To sum up, the invention of seamless calcium line greatly improved the production efficiency and product quality of the casting industry, and also provided great help for the development of the smelting industry.
