How to use the calcium silicon cored wire correctly to ensure the process effect
Will join in the steel smelting, many types of additives for different additives, the utility of the play is different, the calcium silicon cored wire is a kind of common additives, we live in use join order and use the method also different with other additives, only in the correct way of ferroalloys added can better play the role of calcium silicon cored wire, so how to correctly use the calcium silicon cored wire? We follow the calcium silicon cored wire manufacturers to find out.
Solid core with steel line pure calcium calcium treatment response more intense than the calcium silicon line, need to pay attention to calcium processing operations, such as feeding depth and feed velocity, feed line operation, due to the solid core of pure calcium line vapour pressure is big, in order to prevent the natural evaporation of calcium, pure calcium solid core wire feeding must be deeper, a method is to increase the thickness of the sheet metal, to prevent the premature melting depth affect the release of calcium, another method is to improve the feed speed to increase the release of calcium depth, high feed speed to make pure calcium solid core wire can penetrate the slag layer and achieve a certain depth, less slag oxidation of Ca, molten steel for the absorption of calcium, increase the recovery rate of calcium.
Hello linear velocity and feeding line rhythm is pure calcium solid core wire feeding line process, the key parameters of feed speed and rhythm is too fast or too slow will affect the real core is pure calcium wire melting time and degree of oxidation of the metallurgical effect affected, the operator must pay strict attention to molten steel case, once appear, steel rolling, must continue to feed line, after a short pause to prevent spillage.
