Refining furnace is a kind of smelting equipment in the thermal processing industry, and it is mostly used for the final deoxidation and alloying process of molten steel in ferrous metallurgy. Refining furnace refers to the equipment that also has the function of heating and refining steelmaking furnace. It is an important metallurgical equipment used to refine the molten steel melted in the primary furnace (electric arc furnace, open hearth furnace, converter), and can adjust the temperature of molten steel, process buffer, and meet the needs of continuous casting and rolling. The ladle furnace is one of the main equipment for refining outside the furnace.
Refining furnace is a kind of smelting equipment in the thermal processing industry, and it is mostly used for the final deoxidation and alloying process of molten steel in ferrous metallurgy. There are different classifications according to the purpose of smelting, the common ones are argon blowing refining furnace, LF refining furnace and so on.
Main functions of refining furnace:
LF furnace refining is one of the main methods of out-of-furnace refining, the key of which is to quickly create white slag. The purpose of LF slagging is to desulfurize, deoxidize, improve alloy yield, and remove inclusions. However, in the slagging process of aluminum-controlled steel, there are certain contradictions in desulfurization back to silicon, nitrogen increase, and removal of inclusions, which need to be considered as a whole. Rapid and stable production of reducing white slag with good fluidity and certain emulsification in LF is necessary for LF desulfurization, adsorption of inclusions and guarantee of molten steel quality.
Main functions of electrolytic lead equipment refining furnace:
1. Argon stirring function. The argon gas is blown into the molten steel through the breathable brick installed at the bottom of the ladle, and the molten steel obtains a certain stirring function.
2. It has the function of heating up molten steel and keeping it warm. The molten steel is heated by an arc to obtain new heat energy, which not only enables the addition of alloys and adjustment of components during ladle refining, but also the addition of slag, which facilitates deep desulfurization and deoxidation of molten steel. Moreover, the starting temperature of the molten steel required for continuous casting is guaranteed, which is beneficial to the improvement of the quality of the dry casting slab.
3. Vacuum degassing function. After the ladle is hoisted into the vacuum tank, the steam jet pump is used for vacuum degassing, and at the same time, argon gas is blown into the molten steel through the bottom of the ladle to stir the molten steel, which can remove the hydrogen content and nitrogen content in the molten steel, and further reduce the oxygen content and sulfur content. Finally, the molten steel with higher purity and the material with superior performance are obtained. More related product recommendation>>> Copper smelting Rotary furnace
