Description

TECHNICAL FIELD

[0002] In the smelting industry, the molten metal solution is first poured into a ladle, and the ladle is transported to the feeding position of the chain type pouring machine by the overhead crane. The chain plate conveyor includes a driving shaft, a driven shaft and a transmission chain plate wound around the driving shaft and the driven shaft. When the production line is working, the metal solution is first poured into the mold of the chain type pouring machine by tilting the ladle, and then the poured iron-aluminum alloy is cooled and compacted by the water-cooled press roller. The pouring mold is driven forward by the chain plate conveyor. When the aluminum liquid solidifies, the aluminum ingot is separated from the pouring mold by knocking the edge of the pouring mold. The iron-aluminum alloy falls into the receiving hopper. After impact separation, the final product is formed by natural cooling.

During this process, a small amount of iron-aluminum alloy may not be completely separated from the mold, so that the iron-aluminum alloy does not fall into the receiving hopper. The traditional method is to separate the iron-aluminum alloy from the pouring mold by manually knocking the pouring mold.
