Axle low alloy steel sand casting is for construction machinery. The mechanical properties of steel casting are much better than that of iron casting.There are many special properties, such as heat resistance, wear resistance and corrosion resistance,etc. It has good welding performance and is beneficial to the combination and repair of castings.The casting’s size and shape are close to the finished product, saving raw material and simplifying machining. The structure of each part of the casting can be designed uniformly, resistant to deformation and low price.
To obtain excellent steel casting is first,the material in accordance with the casting’s usage with high quality,deoxidation,high temperature and remove harmful impurities;second, good molding materials: strength, breathability, fire resistance, thermal conductivity and expansion; third, the correct molding process design,yield rate:40-70%;fourth,the proper heat treatment;five,reasonable casting structure design.
The statistics from world cast steel production, cast steel accounts for about 1% of steel output; 15-20% of steel casting output. The total output of steel castings has increased by an absolute figure. Increasing proportion of cast alloy steel. Steel casting’s production level sign: 1. output; 2. quality; 3. alloy steel casting proportion; 4. varieties; 5. smelting equipment; 6. products.
Casting influencing factors:
1. pouring temperature and speed: the higher pouring temperature, the better fluidity. But too higher pouring temperature easily lead to hot tear, sand burning, coarse grain and other defects, so it should be properly controlled.
2.casting speed is available to be fast, but not too fast due to it will dash the mold to result in waste casting.
