In order to ensure the safe and smooth completion of the smelting, casting operation and casting process of the construction machinery casting production workshop, the whole production process is coordinated and unified. In the process of smelting and pouring production of engineering machinery castings, the staff should obey the command and execute the instructions accurately and quickly to ensure the safe and smooth completion of the whole pouring process.

Construction machinery casting enterprises should do enough preparatory work before pouring, understand the preparatory work before pouring of construction machinery castings, prevent the phenomenon of insufficient metal liquid and insufficient casting quantity in pouring, so as to ensure the smooth progress of subsequent pouring operations. The preparation work before pouring includes: cleaning the pouring site to ensure the safe and smooth completion of the pouring process; Check the repair quality of the pouring ladle, the drying and preheating situation, and the flexibility and reliability of the transportation and tilting mechanism; Understand the types of pouring alloys for engineering machinery castings, estimate the number of molds to be poured and the weight of the required metal liquid.

Preparation before casting of construction machinery:

1. Calculate the technical parameters and manufacturability of the die-casting machine according to the technical requirements, use conditions and die-casting process specifications of the die-casting plant for construction machinery castings, and select the appropriate model.

2, according to the preliminary concept of die-casting technical parameters and process requirements to calculate the engineering machinery casting process parameters and die-casting size, select the appropriate model.

3. The modeling responsible personnel shall evaluate the working performance and economic effect of the die casting machine, and conduct a comprehensive inspection of the mold and the gating system one hour before pouring to ensure the safety of the mold pouring and the reasonable and smooth position of the gating system, including the yield, qualified rate, productivity and operation stability, reliability and safety.
