carhubIn automobile tires, the cylindrical metal part used to support the tire centered on the axle, that is, the part where the axle shaft is installed in the center of the wheel, they are important parts that connect the brake drum or brake disc, the wheel disc and the half shaft, Automobile wheels can be divided into steel wheels and alloy wheels according to their materials.
Due to the ugly appearance, heavy weight, high inertial resistance, and easy rust of steel wheels, alloy wheels can make up for this problem. Therefore, at present, automobile manufacturers are increasingly using alloy materials to manufacture automobile wheels.
Due to the continuous increase in the utilization rate of automobiles and the extension of mileage, the hardness of automobiles is getting higher and higher, which improves the wear resistance and tensile strength of automobile wheels. However, the alloy materials of automobile wheels cannot fully meet people's needs at present, resulting in Automobile wheels are easily damaged and replaced frequently, which increases the maintenance cost of the automobile.
Cleaning and polishing: the surface of the cut alloy blank is cleaned with a tap water high-pressure spray gun, mechanically polished, and carburized: the alloy blank cleaned and polished in the above steps is placed in a carburizing furnace for carburizing treatment, and the carburizing temperature is 880 ° C to 920 ° C , carburizing time 90min ~ 120min, tempering temperature 360 ℃ ~ 400 ℃, tempering time 50 minutes to 60 minutes.
