The role of cored wire in the steelmaking and foundry industry
Core-spun wire has good deoxidation and desulfurization functions, and is widely used in steelmaking and foundry industries by manufacturers. Core-spun wire can improve the anisotropy of steel in the steelmaking process. Manufacturers can quickly feed silicon-calcium-barium cored wire into molten steel with the help of a wire feeder. In the deep part of the molten steel, the ferroalloy can be melted and dissolved quickly, reduce nozzle clogging, deoxidize, desulfurize, remove inclusions, fine-tune the composition, increase the absorption rate of alloy elements such as Si, Al, Ca, Ba, and improve the quality of steel. Therefore, cored wire is accepted and adopted by more and more steel mills and foundries! There are many kinds of cored wire, such as silicon calcium cored wire, silicon aluminum barium calcium cored wire, pure calcium wire, nodulizer package Core wire, inoculant cored wire, recarburizer cored wire and other alloy materials can be made into cored wire for steelmaking.
The cored wire has a good deoxidation effect in steelmaking and casting. The carbon wire steelmaking has high active ingredients, less sulfur and other impurities, and the water demand is less than 0.5%. It is mainly used as a carburant instead of a carburant. The effect of the carburizer is good, the content of the carbon filament is high, and the absorption rate is high, which is much better than the carburant. The current steelmaking process is pouring through converter-refining and continuous casting. Due to the different time required for each link, the production time of converter or electric furnace is often longer than the rhythm of casting. In order to maintain uninterrupted production, another converter must be arranged to produce the next steel, otherwise production will be interrupted. In the production process, changing the furnace to make steel in advance is called furnace down. Feeding carbon wire is a means to adjust the composition. The carbon-containing powder is wrapped in the iron sheet to make a certain diameter wire, which is directly fed into the liquid steel through the wire feeding machine, so that the carbon content in the molten steel can be precisely controlled. In addition, there are various alloy wires, such as silicon-calcium wire, aluminum wire, S wire, nickel-magnesium wire, etc. Of course, the composition control does not necessarily depend on the feed line to adjust, but the feed line is an effective method for precise composition control.
Core-spun wire has the advantages of uniform core material composition, high filling rate, applicable to various industries, effectively reducing production costs and storage time during smelting. The cored wire can be more convenient to add metallurgical materials to the molten steel during the steelmaking process of the manufacturer. The method of use is to insert the cored wire vertically into the molten iron or molten steel through the wire feeder of the manufacturer, and insert the cored wire, etc. at an ideal depth. Metallurgical materials are fully melted and produce chemical reactions, effectively avoiding the reaction of added elements with air and slag, and improving the absorption rate of metallurgical materials of manufacturers. The cored wire also has the functions of refining and precision casting to change inclusions, alloy and purify molten steel, which plays an important role in improving the quality of cast iron and cast steel, reducing the cost of casting and steelmaking, and improving the economic benefits of cast iron and cast steel.
