  • Description
  • Hebei Shengli Casting Industry Co., Ltd. provides various types of ductile iron castings and gray iron castings. The industry involves auto parts, agricultural machinery parts, construction machinery parts, train and railway parts, cast iron parts for agricultural water conservancy and electric power, etc. Shengli Casting Industry has the production and rough processing capabilities of cast iron parts, advanced production equipment, complete testing equipment, and supports cooperation methods such as drawing customization, sample customization, OEM, etc.

    There are many kinds of brake discs, which are characterized by thin walls, and the disc and the center are formed by sand cores. Different types of brake discs have differences in disc diameter, disc thickness and gap size between the two discs, and the thickness and height of the disc hub are also different. The structure of the brake disc of the single-layer disc is relatively simple. The weight of the casting is mostly 6-18kg.

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

    Production process: most domestic manufacturers use clay sand wet mold, manual mold plate type, grease sand core, individual manufacturers or individual varieties of castings use tree coated sand hot core box process, there are also individual manufacturers in the molding line production tray. Melting mostly uses cupola, but also uses cupola and electric furnace combined melting, the furnace for inoculation treatment and iron liquefaction composition rapid measurement, in order to adjust at any time.
