The function and common operation of silicon calcium cored wire
Calcium silicon cored wire is a kind of cored wire, which is made of strip steel coil and silicon calcium powder to assist the wire feeding process in steel smelting. According to different production environments, the types of cored wire are also different. The application of calcium silicon cored wire is more helpful to increase calcium element in molten steel and avoid the mixing of other impurities. At the same time, the calcium silicon cored wire can be cut into even segments, which also facilitates the rate of steel smelting. So how is the calcium silicon cored wire put in?
Pure calcium solid core wire processing reaction more intense than the calcium silicon cored wire, 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, reducing 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 key parameters of the calcium silicon cored wire feed line process, 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.
