Features of Long Elbow high speed steel castings:
① It is produced by medium frequency furnace smelting and precision casting process.
② . use spectrum analyzer to quantify the product composition, and the product quality can be stable.
③ Special high manganese steel casting formula is adopted to realize high wear-resistant product characteristics.
④ . each product is marked with heat number, and each furnace of molten steel shall be tested.
⑤ . strictly control the tempering process of castings to ensure the safety of high-pressure pumping.
⑥ . all dimensional parameters meet the installation requirements of the host.
Key points of high speed steel casting products:
1. There are many kinds of casting. The installation dimension of the pump car casting is relatively high. Generally, the precision casting can make the installation smooth and save the time of pipe replacement on site.
2. For castings with special properties and consistent casting quality, it is necessary to detect the composition of the finished product. In this way, a spectrum analyzer is needed, which can accurately quantify the composition of the casting product and the percentage of each composition.
3. There are many formulas of high manganese steel casting, the main difference is that it tends to some properties. For example, the elbow and taper pipe used in the pump truck are required to be wear-resistant and impact resistant, which requires repeated experiments to obtain an optimal formula.
4. The elbows and cones used in the pump truck need to bear high pressure. The high manganese steel castings are hard and quenched after being discharged from the box. If there is no good tempering process, it will lead to cracking or accelerated grinding.
