Method used for cleaning surfaces of castings, surfaces of pouring gates and surfaces of dead heads

Abstract

The invention discloses a method used for cleaning the surfaces of castings, the surfaces of pouring gates and the surfaces of dead heads. The castings, the pouring gates and the dead heads are arranged in a roller of a casting machine. The method comprises the steps that cleaning blocks are placed in the roller of the casting machine, the cleaning blocks, the castings, the pouring gates and the dead heads are made to roll over along with the roller of the casting machine, the cleaning blocks continuously conducts friction on the castings, the pouring gates and the dead heads so as to remove sands on the surfaces of the castings, the surfaces of the pouring gates and the surfaces of the dead heads, and therefore the purpose of cleaning the surfaces of the castings, the surfaces of the pouring gates and the surfaces of the dead heads is achieved.

Description

technical field

[0001] The invention relates to a method specially used for cleaning the surface of castings, runners and risers. It places a sharp-edged and wear-resistant cleaning block in the drum of the pouring machine. Together with the runner and riser, with the rotation of the drum, the surface cleaning of castings, runners and risers is realized. Background technique

[0002] The vertical split DISA molding machine used in the casting production line has relatively high efficiency under normal production conditions. The DISA230B vertical split molding machine can produce at least more than 1,600 tons of products per month. Adding the weight of runners and risers, the monthly weight exceeds More than 2,000 tons. For green sand molding, when molten iron is poured into the cavity and cooled and solidified in the cavity, a thick layer of sand will stick to the surface. The sand must be cleaned up in the subsequent process, and the cleaning of the subsequent process can ...
