The cored wire has a good deoxidizing effect in steelmaking and casting. The carbon wire has high effective components in steelmaking, contains less other impurities such as sulfur, etc., and has a moisture requirement of less than 0.5%. It is mainly used to replace carbon increase Recarburizers have a good effect on recarburization, and the carbon content is high, and the absorption rate is also high, which is much better than recarburizers.
At present, the steelmaking process is carried out through converter (electric furnace)-refining-continuous casting (die casting). Because each link requires different time, the production time of converter or electric furnace is often longer than the rhythm of casting. To maintain uninterrupted production, another converter (electric furnace) must be arranged to produce the next furnace of steel, otherwise production will be interrupted. During the production process, the furnace is changed to make steel in advance, which is called the furnace.
But it must be noted that the cored wire must have a wire feeding machine before it can be used. The wire feeding machine can accurately put each section of the cored wire into the furnace accurately. Feeding the carbon wire is a component adjustment. Means, the carbon-containing powder is wrapped in the iron sheet to make a wire with a certain diameter, which is directly fed 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 various alloy wires such as silicon calcium wire, aluminum wire, sulfur wire, nickel-magnesium wire, etc. Of course, the composition control may not be adjusted by feeding the wire, but the feeding wire is a comparison of precise control of the composition. effective method.
So in the process of using the cored wire, the feeding method of the wire feeding machine is a very important step!
