When selecting the material for the sliding gate mechanism, consider the following: High-temperature resistance: Since the sliding gate mechanism operates in the high-temperature environment of molten metal, the material must possess excellent high-temperature resistance and be able to withstand high-temperature oxidation and corrosion. Wear resistance: The sliding gate mechanism needs...

During converter steelmaking, a large amount of molten slag is produced during smelting. This slag flows into the ladle during converter tapping, affecting the life of the ladle's refractory materials. It also causes resulfurization and rephosphorization of the molten steel, impacting its quality. It also increases the consumption of ferroalloys...

The tundish stopper mechanism is a critical piece of equipment in the continuous casting process, primarily used to control the flow of molten steel from the tundish to the mold, directly impacting ingot quality and production safety. Its core functions include: Precision Control of Molten Steel FlowCore Function: Dynamically adjusts...

The primary material used in ladle sliding nozzles is refractory. Specifically, the upper and lower slides are constructed of fired oil-impregnated aluminum-carbon refractory, the upper and lower nozzles are constructed of unfired oil-impregnated aluminum-carbon refractory, the upper seat is constructed of corundum castable bricks, and the lower seat bricks are...

The primary function of the ladle slide nozzle is to control the flow of molten steel, achieving precise regulation of the flow from the ladle to the continuous casting tundish, ensuring a balanced inflow and outflow of molten steel, and thus ensuring smooth continuous casting operations. Specifically: Controlling Molten Steel...
