Brake disc casting

1. Production technology: there are many kinds of brake discs, which are characterized by thin wall, and the disc and center are formed by sand core. For different types of brake discs, there are differences in disc diameter, disc thickness and two disc gap dimensions, and the thickness and height of disc hub are also different. The brake disc structure of single-layer disc is relatively simple. The casting weight is mostly 6-18kg.

2. Technical requirements: the outer contour of the casting shall be processed completely, and there shall be no casting defects such as shrinkage porosity, air hole and sand hole after finishing.The metal lographic structure is medium flake type, graphite type, uniform structure and small section sensitivity (especially small hardness difference).

3. Production process: most domestic manufacturers use clay sand Wet Mold, manual template mold and grease sand core. Individual manufacturers or individual varieties of castings use tree is coated sand hot core box process, and some manufacturers also produce car discs on the molding line. Cupola is mostly used for smelting, and cupola and electric furnace are also used for smelting. Inoculation treatment and rapid measurement of chemical composition of molten iron are carried out in front of the furnace for adjustment at any time.Zhuo Meng (Shanghai) Automobile Co., Ltd
