Description

Technical Field

[0001] The utility model relates to a steel ingot grinding machine, belonging to the technical field of metallurgical equipment. Background Art

[0002] In steel mills, the casting of die-cast steel ingots (not continuous casting billets) can result in varying degrees of surface defects on the finished ingot due to factors such as pouring speed control, mold temperature, mold condition, and the gap between the riser brick and the mold. Therefore, to improve yield and facilitate subsequent rolling or forging processes, the surface of the die-cast ingots must be ground.

[0003] In the prior art, due to the need for demolding, the two ends of the die-cast ingot have different dimensions and a certain taper, making it impossible to use automatic grinding equipment. Therefore, grinding can only be performed by workers using handheld grinding wheels. Due to the heavy weight of the die-cast ingot, this grinding method requires the use of a lifting device to flip the die-cast ingot to ensure comprehensive grinding of the die-cast ingot, resulting in relatively low grinding efficiency.
