Description of the effect of seamless calcium wire

　　The main products are high calcium core-clad wire,seamless calcium wire,pure calcium core-clad wire and other products,and a number of large domestic steel mills to establish a long-term cooperative relationship,we continue to improve the production process,research and development attitude and continuous innovation ability,by the new and old customers praise!

　　The treatment effect of calcium on molten steel and the process principle and effect of composite pure calcium wire.Calcium is added into molten steel and part of it dissolves into molten steel,becoming dissolved calcium in steel.Part of seamless pure calcium line evaporates in the form of steam;Some of them react with Al2O3 inclusions or S in steel to form impurities,which float up into slag during refining and continuous casting after the treatment,and the residual part remains in steel as inclusions.

　　As we all know,seamless pure calcium cored wire has a very big role in our steel making and cast iron,because it has a very large flexibility,we can do different seamless pure calcium cored wire according to different alloys.

　　Calcium iron wire

　　In the production of cast iron,the use of seamless calcium wire desulfurization of molten iron,spheroidization and inoculation of casting plants continue to be added,widening faster and faster.Use seamless pure calcium in early development package produce ductile iron core skills of Germany as an example,the end of 1989 the country as long as a foundry with seamless pure calcium packet core method to produce ductile iron,and in 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.To produce high quality products with low cost is the policy sought by steel mills and foundries all over the world.The practice including our country has proved that the core-wrapped wire technique is one of the simple and agile techniques and methods to complete this wish in many aspects of molten steel and hot iron treatment.
