[0002] Ladle bath brick is a kind of refractory material, mainly used for ladle lining. Ladle bath brick is usually made of high alumina, mullite or corundum and other raw materials, through high temperature firing process. It has excellent high temperature performance, corrosion resistance and thermal shock resistance, can withstand the high temperature and chemical erosion of molten steel, and prevent molten steel leakage and pollution.

[0003] The existing ladle pool bricks have weak compressive performance and cannot effectively resist the influence of external pressure on the ladle pool bricks. The ladle pool bricks are prone to cracking or deformation when subjected to greater pressure, resulting in a short service life. For example, a lightweight insulating magnesium-aluminum-carbon brick for a ladle pool disclosed in announcement number CN201820493155.7 does not have a compressive structure, resulting in insufficient strength during use. When subjected to external pressure and impact force, the use effect and service life of the magnesium-aluminum-carbon bricks are affected, and the internal structure of the magnesium-aluminum-carbon bricks is damaged.

[0004] Therefore, it is necessary to invent a ladle molten pool brick with high compressive strength to solve the above problems. Utility Model Content
