Silicon Carbon Alloy Powder

Introduction

Silicon Carbon Alloy Powder is a chemical substance. The production of silicon calcium barium alloy by carbothermal method is to smelt carbon reducing agent and lime, silica, Baryte and other raw materials in the same submerged arc furnace. Electrosilicothermal method is the use of siliceous reducing agents to reduce lime and barium ore to obtain silicon calcium barium alloys. The mixed method is to first create conditions for reducing Calcium oxide in the furnace to obtain calcium silicon alloy. Then, silicon is used as a reducing agent to reduce barium ore and obtain a silicon calcium barium alloy. The mixed method for smelting silicon barium alloy combines the process characteristics of carbon thermal method and electric silicon thermal method, which can not only obtain the same grade of alloy quality as carbon thermal method, but also lower impurity content.

This product is the best substitute for traditional alloy Oxygen scavenger, realizing the linkage reaction of deoxidation, desulfurization and inclusion removal. The product has the characteristics of purifying molten steel, rapid deoxidation and simultaneous desulfurization. Silicon aluminum barium calcium is an alloy used for deoxygenation in steelmaking, consisting of the following weight percentages: silicon (Si) 10-50%, aluminum (Al) 5-25%, calcium (Ca) 5-25%, barium (Ba) 5-20%, with iron and unavoidable impurities remaining.

Advantage

By adjusting the appropriate element ratio, the free oxygen in the steel can be reduced, and deoxygenated inclusions in the molten steel can be fully removed, resulting in residual inclusions denaturation. Si is a basic deoxygenation element. If its content is less than 10%, the deoxygenation ability of the alloy is insufficient, while if its content is higher than 30%, the specific gravity of the alloy is too small, preferably between 22-28%. During the sinking process of Al in molten steel, it can gradually react with oxygen, reducing the accumulation of aluminum oxide while deoxidizing, and improving the yield of aluminum. Its content is between 5-25%, especially 7-12%, which is more suitable. Ca is a strong deoxygenation element in this alloy. When it is combined with the above strong alkaline compounds such as Si, the organic combination of precipitation deoxidization and diffusion deoxidization is realized, which completely changes the problem that the traditional Oxygen scavenger does not react sufficiently, and the deoxidized products are retained in the molten steel, which seriously affects the internal quality of the molten steel, and at the same time, the inclusion modification is also realized. And Ca can play a role in regulating acidity and alkalinity.

Features

Compared with the existing alloy Oxygen scavenger, Silicon Carbon Alloy Powder adopts the form of deoxidized metal and slag pre melting, and the modifier has low melting point and fast slag forming; At the same time, the deoxygenation products naturally form slag. Completely different from synthetic slag mainly composed of high melting point substances such as lime. As the silicon aluminum barium calcium complex Oxygen scavenger is rapidly slagging and fully deoxidizing the molten steel, it provides conditions for desulphurization in tapping process and lays a good foundation for deep desulphurization in subsequent secondary refining. This product can change the distribution of impurities in steel, improve the fluidity of molten steel, improve the mechanical properties of steel, and can significantly increase the alloy recovery rate, reduce alloy consumption, improve the quality of steel products, with low energy consumption. It is the best substitute for traditional alloy Oxygen scavenger.
