What are the benefits of the application of calcium silicon cored wire to steelmaking
Calcium silicon wire is a kind of cored wire. Various additives are added in the steel smelting process. If these additives are directly added, they will affect the temperature of molten steel due to factors such as particle size. Additives are added to the cored wire and broken into appropriate particle size, which not only facilitates the addition of additives, but also avoids the infiltration of other impurities. There are many applications of silicon-calcium wire in steel smelting. Let's take a look at the benefits of its application for steelmaking.
The method of use is to insert the cored wire vertically into the molten iron or molten steel through the wire feeding machine of the manufacturer, and the metallurgical materials such as the cored wire will be fully melted and chemical reactions will occur at the ideal depth, effectively avoiding the addition of elements and The reaction of air and molten slag improves the absorption rate of the manufacturer's metallurgical materials.
The vaporization temperature of Ca is about 1480°, and the temperature of refined molten steel is 1580°~1600°. In this way, the metal Ca fed into the molten steel immediately vaporizes at the initial stage, and its volume expands violently.
The deoxidation performance of Ca is higher than that of Al, so the binding capacity of Ca and O is stronger. Therefore, the vaporized Ca can react with the inaccurate inclusions Al2O3 to make it denatured to form calcium aluminate and other substances and float up.
The calcium feed line for the converter molten steel is fed when argon is blown after the steel is tapped. Generally, the calcium line is fed while blowing argon. The stirring of the argon blow can improve the shape of inclusions, promote the floating of inclusions, and improve the fluidity of molten steel. The role of.
The above is the application advantages of calcium silicon cored wire for everyone to share. The application of calcium silicon cored wire in steel smelting will rarely bring other impurities into the molten steel, and the calcium in the calcium silicon cored wire is more It can provide the required calcium source for the molten steel, increase the calcium content of the steel, and also have a certain effect on the toughness of the steel. As a calcium silicon cored wire manufacturer, the calcium silicon cored wire we provide has undergone strict quality inspection, and the processing links are also strictly controlled by technology. Welcome to inquire.
