The bimetal wear-resistant elbow produced by Huazhan has advanced and stable technology. The wear-resistant pipe is manufactured using the lost foam vacuum suction casting bimetal process. This process is between sand casting and wax mold casting. It is a semi-precision casting process. The surface dimensional accuracy and roughness are two levels higher than that of sand casting. Due to the casting system (including sprue, lateral runner, inner runner) , inside the model) is completely isolated from the sand, so there will be no sand washing and sand inclusion phenomena in the traditional sand casting process; since it is cast under a vacuum system, there will be no defects such as pores.
The bimetal wear-resistant elbow is wear-resistant, impact-resistant, and has a long service life. The bimetal wear-resistant elbow has high hardness and is used for crushing inferior coal, anthracite, etc. It is safe to operate. The bimetal wear-resistant elbow is used for pneumatic and pumping. Slurry and other material transportation pipelines. It has the characteristics of fast flow rate and large flow rate. The conveying medium continues to impact, wear and corrode the pipe wall for a long time, causing the pipe to fatigue and gradually wear out.
The bimetal wear-resistant elbow contains Cr, Ni, V, Mo, W, Cu and other alloy elements. It not only has high hardness, but also has certain mechanical properties. It has good welding performance at room temperature and has It has cutability and the possibility of on-site drilling, and it also has certain corrosion resistance. In actual use, it is suitable for use in water slag pipes in steel plants or coal washing pipes in coal preparation plants. Very good results have been achieved. Compared with high manganese steel materials under the same conditions, its unit wear is 1/5 times that of high manganese steel, and its service life is 4-5 times that of high manganese steel. Elbows and branch pipes can Used in conjunction with seamless pipe sections, installation and maintenance are more convenient.
