Seamless pure calcium cored wire used in what steel plant
With the rapid development of science and technology, China has become a world power in the field of smelting. At the same time, the rapid development of science and technology also makes the efficiency of smelting field higher and higher, and the production quality is getting better and better. Let's talk about the use of seamless pure calcium cored wire in those steel mills is very high. Seamless pure calcium cored wire plays a very important role in steelmaking and cast iron. Because of 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 molten iron desulfurization, spheroidization and inoculation of foundry is constantly added, the expansion rate is 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. Producing high quality products at a lower cost is the permanent policy sought by steel mills and foundries all over the world. The practice including our country has proved that the cored wire skill is one of the most simple and efficient skills and methods in many aspects of molten steel and molten iron treatment in all countries in the world. To sum up, the invention of seamless calcium wire has greatly improved the production efficiency and product quality of the foundry industry, and also provided a great help for the development of the smelting industry.
