In the valve castings should do the following several preparations:

1, the temperature control (to the temperature of the pouring process to determine the insulation furnace, in addition to the air box, filter tank and casting the front of the point of the temperature control)

2, aluminum liquid pouring process in the interface, the accident flow of the seal and the accident box in place, capacity and dry conditions;

3, transfer flow tank, casting flow tank, funnel (distribution bag), control raft, slag box and tool heating and drying;

4, casting transmission control system, including hydraulic, instrument operation and display;

5, the degree of smoothness of the mold, the location and location of the ingot and dry conditions (including lubrication);

6, the cooling water debugging and water temperature situation;

7, the production of alloy, the specifications of the process parameters to confirm, etc., these are each casting can not ignore the work.

In addition to some of the valve castings preparation but also targeted, according to the production of the alloy, specifications and previous production, quality problems, targeted to take the necessary measures to ensure the smooth casting process, product quality.
