In order to ensure that the casting production can be carried out smoothly and the quality of the cast products meets the requirements of the customers, a series of preparatory work must be carried out before the casting work is carried out, and the inspection work before the start of construction is indispensable. The following preparations should be made in aluminum alloy casting: (1) Temperature control (determine the temperature control of each point of the holding furnace, the online deaeration tank, the filter box and the front end of the casting chute by the temperature drop of the transfer process); (2) Sealing of each pair of interfaces, accident flow ports and the location, capacity and drying of the accident tank in the aluminum liquid transfer process; (3) Heating and drying of the transfer launder, casting launder, funnel (distribution bag), flow control slag, slag box and tools; (4) The casting transmission control system includes the operation and display of hydraulic and instrumentation; (5) The smoothness of the crystallizer, the placement position and the position of the spindle head and the drying condition (including lubrication); (6) Commissioning inspection of cooling water and water temperature conditions; (7) Confirmation of process parameters for the production of alloys, specifications, etc. These are not negligible work for each casting. In addition, some casting preparations must be targeted. According to the alloys, specifications and problems of previous production and quality, we have taken necessary measures to ensure the smooth casting process and qualified products. In the same way, before carrying out other types of casting work, the corresponding inspection work should also be carried out.
