The difference between slagging agent and slagging agent

First, the mechanism of action and use of slag removal agent

Slagging agent refers to a dosage form used to reduce the material exchange between the metal liquid and the furnace wall, so as to achieve the slagging effect. The mechanism of action of such slagging agent is that the oxide on the metal surface is decomposed through chemical reaction, and the impurities in the metal are slagged and float on the metal surface, thus reducing the impurity content of the metal and reducing the oxidation of the metal surface. To achieve the purpose of improving the chemical composition and physical properties of metals. Different kinds of slag removal agents have different chemical compositions, but the principle of their action is roughly the same, that is, chemical reactions are generated between the metal and the slag to melt and separate, to achieve the purpose of slag removal.

The method of use of slag remover is generally seasonal addition or reactive addition. The selection method should be determined according to the degree of slag removal required. Seasonal addition means that slag removal agent is added in stages in the smelting process to promote the separation of slag and mud. Reactivity addition refers to taking the impurity elements in the slag as the target, selecting a specific slag removal agent, adding a specific dosage to treat the slag, eliminating the impurity elements or reducing to separate the desired component materials.

Second, the mechanism of action and use of slagging agent

Slagging agent refers to the formation of independent bubbles on the interface of metal liquid and gas, so as to achieve the purpose of slag removal. The mechanism of slagging agent is to use high-pressure gas injection into the molten pool, and then form an independent bubble on the surface of the metal liquid to separate the slag and metal. In addition, the high temperature porcelain fire strength of the slagging agent is large, and it has strong permeability resistance when melting, which can effectively resist the erosion and damage of impurities such as metal slag and carburizing, and also prevent the leakage of metal liquid.

The method of use of slagging agent is relatively simple, usually in the way of gas injection to make it used in the liquid metal surface, through the physical action to generate bubbles, rise to the metal surface, the slag is separated from the metal. However, the slagging agent must choose the appropriate pressure and speed, otherwise it will cause impurities in the metal to be doped, affecting its physical properties.

【 Conclusion 】

Slagging agent and slagging agent are the same in the goal of slagging, but their use method and mechanism of action are different, and the choice of different dosage forms should be determined according to the specific needs to achieve a good slag removal effect.
