CaSi Cored Wire
CaSi Cored Wire Description
CaSi cored wire is a cored wire product with a large export volume, which plays an important role in steelmaking and casting processes. The powder core is alloy powder, which is wrapped by a cold-rolled steel strip and pressed into shape with professional wire pressing equipment. The main reason why the cold-rolled steel strip is used as the skin of the CaSi cored wire is that the cold-rolled steel strip has good plasticity and a low melting point. It can be used in the ladle or furnace to smoothly make the calcium silicon powder core reach the predetermined ideal depth. Compared with traditional metallurgical materials, CaSi cored wire is more affordable in price and is often used by many manufacturers in steelmaking and casting. For CaSi cored wire manufacturers, it is the premise of CaSi cored wire production to be familiar with the raw materials of silicon calcium and master the requirements of raw materials.
To produce CaSi Core Wire, the first step is preparing for the production of CaSi cored wire raw materials. There are many methods for producing CaSi cored wire and the raw materials prepared are slightly different, so the frequently used one-step method is used to produce CaSi cored wire. As it is often used for one-step production of calcium silicon packet core want to refine the calcium silicon packet core need to prepare the ferroalloy raw materials are silica, limestone, coke, wood, charcoal, coal. For the cored wire, the ferroalloy raw materials that need to be prepared to smelt the calcium silicon cored wire are silica, lime, coke, wood, charcoal, and bituminous coal.
What is CaSi cored wire?
Since CaSi cored wire belongs to alloy material, we can customize its content. However, the general requirements of the steelmaking and casting process are roughly the following two kinds of content. Of course, if you have special requirements, you can also contact customer service for procurement guidance.
|Types||Main composition||Diameter||ThickStrip||Content Weight||Uniformity|
|CaSi cored wire||Si55 Ca30||13-13.5||0.4±0.2||230||2.5|
CaSi cored wire can deoxidize the molten steel deeply in steelmaking, deoxidize more thoroughly, calcium element effect is better, can effectively improve the shape of inclusion in the molten steel so that the slag discharge is more convenient. In the casting aspect, the CaSi cored wire can effectively improve the flow performance of molten iron and make the chemical reaction between elements play a sufficient role. In terms of procurement cost, the CaSi cored wire is an upgraded product of CaSi alloy, the procurement cost is greatly reduced, but the effect is better than the previous ordinary alloy. The CaSi cored wire does not produce harmful gas during smelting, which effectively reduces environmental pollution, and is the recommended material for environmental metallurgy at present.
Instructions for use
Many types of additives are added in steel smelting, and for different additives, their effects are different. CaSi cored wire is a common additive in our lives. The order of adding and the method of use are also different from other additives. Only in accordance with the correct way of adding ferroalloy can better play the role of CaSi cored wire, so how to use the CaSi cored wire correctly?
CaSi cored wire reacts more strongly with molten steel, so attention should be paid to calcium treatment operations, such as feeding depth and wire feeding speed. During the feeding operation, due to the high vapor pressure of the CaSi cored wire, in order to prevent the natural evaporation of calcium, the CaSi cored wire must be fed deeper. One method is to increase the thickness of the strip to prevent its premature melting from affecting the calcium release depth. Another method is to increase the feeding speed to increase the calcium release depth. The higher feeding speed enables the CaSi cored wire to penetrate the slag layer and reach a certain depth, reduce the oxidation of Ca by the slag, and increase the effect of molten steel. The absorption of calcium improves the recovery rate of calcium.
