The hot metal ladle is a specialized container used for holding and transporting molten iron, widely applied in the processes of ironmaking and steelmaking. It connects the blast furnace and the converter, used to transport molten iron to the next process. Desulfurization, dephosphorization, and other pre-treatment operations can also be carried out inside the hot metal ladle.
Refractory used in hot metal ladles typically need to possess characteristics such as anti-erosion, high strength, and resistance to thermal shock, in order to adapt to the working conditions of high temperature and severe wear in hot metal ladles. In areas where damage is more severe, such as the slag line, alumina-silicon carbide bricks or magnesia-carbon bricks are used, and there are also cases where castables are used for overall casting.
