[0002] The motor casing for automobiles is one of the main components used in the air conditioner in the automobile. Since it needs to be connected with other components to ensure the fixation of the air conditioner, the requirements for the physical properties of the automobile motor casing are particularly high, while the traditional automobile After the corresponding raw materials are used for the motor shell, the casting process is carried out after smelting. Most of the specific processes for the optimization of its physical properties are processed in the subsequent heat treatment process. However, optimization in the heat treatment process not only consumes more large, increasing the production cost, and the grain size of the product can no longer meet the requirements of automobiles

Abstract

The invention discloses a production process of motor shells for vehicles. Raw materials of the motor shells for the vehicles comprise the following components in percentage by mass: 0.2-0.5% of C, 1.5-2.6% of Al, 0.6-0.8% of Mn, 0.5-1.1% of Cu, 0.8-1.6% of Si, 0.2-0.4% of Mo, 0.7-1.9% of Ti, S not more than 0.02%, N not more than 0.02%, P not more than 0.02%, and the balance of Fe and inevitableimpurities; the production process of primary smelting, secondary smelting, ternary smelting, and then casting, heat treatment and machining is adopted to obtain the needed motor shells for the vehicles; and through the mode, the content of impurities in castings can be greatly reduced, the grain size of the castings is increased, the physical performance of the motor shells for the vehicles is finally realized, in particular, the yield strength is more prominent, and the use quality is improved.
