Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a carbon steel casting pouring gate grinding machine. Background Art

[0002] The gate of a carbon steel casting refers to the channel from the runner to one end of the mold cavity during casting. It is the smallest and shortest part of the casting system. In metal casting, it refers to the entrance and channel for the molten metal to enter the mold during casting. After molding, the gate is the first to solidify and seal.
