[0002] Magnesia-calcium bricks are widely used in steelmaking and other industrial fields. For example, in the steelmaking process, magnesia-calcium bricks are used in key parts such as the tuyere of the side-blown converter, the top of the open-hearth furnace and the oxygen-blown converter. In addition, magnesia-calcium bricks are also widely used in refining equipment such as AOD furnaces, VOD furnaces and LF furnaces, showing good use effects. With the expansion of stainless steel and various clean steel production capacity, the demand for magnesia-calcium bricks is also increasing.

[0003] Existing magnesia-lime bricks do not have a structure that is convenient for stacking. For example, a low-carbon magnesia-lime brick for ladle slag line disclosed in application number CN202222341937.8. Existing magnesia-lime bricks of this type lack a certain structure that is convenient for stacking, which makes the magnesia-lime bricks not stable enough when transporting and stacking. Without a special stacking structure, the contact area and friction between the bricks will be reduced, resulting in the inability to fully utilize the space during storage and transportation, increasing storage and transportation costs. The unstable stacking will also cause impact and extrusion, increasing the risk of damage.

[0004] Therefore, it is necessary to invent a magnesium-calcium brick that is easy to stack to solve the above problems. Utility Model Content
