Introduction of Ishikawa Brand External Refining Purification Agent

As we all know, there are many factors that affect the quality of molten steel, the main one is the presence of harmful gases in molten steel, such as oxygen, sulfur, hydrogen, nitrogen and inclusions, etc. In addition, refractory materials will also have a certain impact on the quality of molten steel.

　　The purpose of out-of-furnace refining purifiers is:

(1) Reduce the content of harmful elements such as oxygen, sulfur, hydrogen and nitrogen in molten steel.

(2) Change the shape and composition of inclusions in steel, eliminate slag pores, enhance fluidity, and improve the surface finish of castings.

(3) Adjust the temperature of the molten steel to make it uniform.

(4) fine-tune the chemical composition of steel and narrow its scope.

　　The use of refining purification agent outside the furnace:

1. The scope of use of refining purification agent outside the furnace: suitable for cast iron, cast steel, alloy steel, stainless steel and other casting types, as well as various casting types of different methods, such as coated sand casting, resin sand casting, lost foam casting, etc.

2. The amount of refining purification agent used outside the furnace: calculated according to the weight of liquid metal, the amount added is 1‰, and the amount used in special cases is 2.

3. Use method of refining and purifying agent outside the furnace: Before pouring molten steel into the casting ladle, add the refining and purifying agent outside the furnace to the bottom of the casting ladle. After the molten steel fills the casting ladle, first remove the slag on the surface of the molten steel, then cover the slag remover on the surface of the molten steel, let stand for two minutes, and then pour after the refining and purifying agent acts. Do not remove slag before pouring, just clean up the scum on the pouring bag and press a piece of slag-blocking cotton to pour.

4. The preservation method of the refining purification agent outside the furnace: the refining purification agent outside the furnace that has been opened and used should not be exposed to the air for a long time, and attention should be paid to prevent mixing and moisture.
