About the role of seamless calcium wire in steelmaking and cast iron

2021-10-08 08:58:16

  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.

Core-wrapped wire manufacturers

  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.

About the role of seamless calcium wire in steelmaking and cast iron

  Advantages of seamless calcium wire:

  (1)The recovery rate of calcium element is improved.After feeding solid core pure calcium core-clad wire developed by our factory,the recovery rate of calcium element for low carbon and low silicon steel represented by SPHC is more than 25%on average,and the use efficiency of calcium element is about 52%higher than that of silicon calcium core-clad wire.

  (2)Significant cost reduction.The feeding weight of ton steel solid core pure calcium cored wire is only about 38%of that of silicon calcium cored wire.

  (3)more conducive to pure steel production.

  (4)Reduce and eliminate nozzle clogging of continuous cast steel.

  (5)The operation intensity is reduced.
