There are many kinds of core-core wire, including steel core-making wire and casting core-making wire. The general varieties are: calcium silicate core-making wire, pure calcium wire, barium silicate calcium core-making wire, barium silicate calcium core-making wire, carbon wire, etc., which are used in steel making. Casting is generally used more: spheroidizing agent core-coated wire, inoculating agent core-coated wire and so on are used a little more, which is according to the different things produced by the foundry or steel mill, the demand for core-coated wire is also different. Carbon line for foundries or steel mills are more commonly used products, because its price is low, and the effect of carburizing agent is very good, can be used in cast steel cast iron.
Cored wire has a good deoxidation in steel making and casting. Carbon wire has a high effective component in steel making, contains less other impurities such as sulfur, and has a moisture requirement of less than 0.5 percent. Mainly instead of carburizing agent to carburizing effect is good, and the carbon line component content is high, the absorption rate is also high, than the carburizing agent effect to a lot.
At present, the process of steelmaking is through the converter (electric furnace) - refining - continuous casting (die casting) for pouring, because each link needs different time, often the production time of converter or electric furnace is longer than the rhythm of casting, to maintain uninterrupted production, must arrange another converter (electric furnace) to produce a steel, otherwise it will cause production interruption, In the production process to change the furnace in advance of steel is called inverted furnace.
Carbon feeding line is a means of composition adjustment. Carbon containing powder is wrapped in iron sheet to make a line with a certain diameter, which is directly sent into the liquid steel by wire feeding machine, so that the carbon content in the steel can be accurately controlled. In addition, there are all kinds of alloy wire such as: silicon calcium wire, aluminum wire, sulfur wire, nickel magnesium wire and so on. Of course, the composition control may not be adjusted by feeding wire, but feeding wire is a more effective method of accurate composition control.
