Cored wire has the advantages of uniform core composition,high filling rate,cored wire can be used in many industries,effectively reducing the production cost and storage time in the smelting process.
The cored wire can more conveniently put the metallurgical materials into the steel water during the steelmaking process of the manufacturer.Its use method is to vertically insert the cored wire into the molten iron or steel through the manufacturer's wire feeder.At the ideal depth,the metallurgical materials such as the cored wire will be fully melted and produce chemical reactions,effectively avoiding the reaction between the added elements and air and slag,and improving the absorption rate of the metallurgical materials of the manufacturer.The cored wire also has the function of refining and precision casting,changing inclusions,alloying and purifying molten steel,which plays a significant 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.
Generally,there are many kinds of cored wires,including silicon aluminum barium calcium cored wire,silicon calcium cored wire,silicon barium calcium cored wire,inoculant wire,spheroidizing agent wire,carbon wire and so on.The purpose and effect of each kind of cored wire are different,so when selecting cored wire,we must pay attention to selecting the appropriate cored wire according to the actual situation.
Silicon aluminum barium cored wire is a Ferroalloy product made by the cored wire manufacturer by mixing silicon powder,aluminum powder and barium powder and coating with steel strip.It is mainly used as deoxidizer and desulfurizer in the steel-making process.
The silicon calcium barium cored wire has the functions of deoxidation and desulfurization,and is widely used by manufacturers in steel-making and casting industries.The silicon calcium barium cored wire can improve the anisotropy of steel in the process of steelmaking.The manufacturer can quickly input the silicon calcium barium cored wire into the molten steel with the help of a wire feeder.In the deep depth of the molten steel,the ferroalloy can quickly dissolve,reduce the blockage of the nozzle,deoxidize,desulfurize and remove inclusions,and fine tune the composition,Improve the absorption rate of silicon,calcium and barium and the yield of steel,reduce the production cost of manufacturers and ensure the stability of components.
Carbon wire:cored wire has a good deoxidation effect in steelmaking and casting.Carbon wire has high effective components in steelmaking,contains less other impurities such as sulfur,and has a moisture requirement of less than 0.5%.It is mainly used to replace carburizing agent for carburizing effect,and the content of carbon wire is high,the absorption rate is also high,which is much better than the effect of carburizing agent.
At present,the steel-making process is cast through converter(electric furnace)-refining-continuous casting(mold casting).Because the time required for each link is different,the production time of converter or electric furnace is often longer than the casting rhythm.To maintain uninterrupted production,another converter(electric furnace)must be arranged to produce the next furnace of steel,otherwise the production will be interrupted.In the production process,change a furnace to make steel in advance,which is called furnace switching.
Carbon feeding line is a means of composition adjustment.The carbon containing powder is wrapped in the iron sheet to make a line with a certain diameter,which is directly sent into the liquid molten steel through the wire feeder,and the carbon content in the molten steel can be accurately controlled.In addition,there are all kinds of alloy wires,such as silicon calcium wire,aluminum wire,sulfur wire,nickel magnesium wire,etc.of course,the composition control is not necessarily adjusted by wire feeding,but wire feeding is a more effective method for accurate composition control.
