Smelting method of calcium silicon alloy
Steel casting industry insiders believe that the calcium silicon alloy are already very familiar with, although it is very common products, but still have customer asked, are the calcium silicon alloy deoxidizer or inoculant, yes, the purpose of the calcium silicon alloy really many, have played an important role in many fields, by the calcium silicon alloy factory next to introduce for everybody.
The calcium silicon alloy is a kind of silicon and calcium binary alloy, DNA is mainly used for high temperature alloy, with the development of continuous casting and ladle refining outside the furnace, the calcium silicon alloy consumption increasing rapidly, the calcium silicon alloy production method has two kinds of step method and the two steps, one step method is in an electric furnace, with carbon reduction of silica and lime produces the calcium silicon alloy, two steps, Now calcium carbide is produced in one furnace, and then calcium carbide is added to silica, lime and coke in another furnace to produce silicon calcium alloy. Calcium silicon alloy is an ideal compound deoxidizer and desulfurizer. Silicon alloy not only has strong deoxidation ability, deoxidation products are easy to float, easy to discharge, but also can improve the performance of steel, improve the plasticity, impact toughness and fluidity of steel. At present calcium silicon alloy can replace aluminum for final deoxidation. Is widely used in, low carbon steel, stainless steel and other steel and nickel base alloy, titanium base alloy and other special alloy production; And suitable for the bof steel training workshop used as heating agent; It can also be used as inoculant of cast iron and additive of nodular cast iron production.
