Product Description
High chromium spiral extruder products: according to the characteristics of raw materials in domestic brick making industry, the proportion of industrial waste residue, coal gangue, shale, etc. is relatively large. The traditional high chromium spiral extruder products have insufficient wear resistance. Generally, the production of about 10 million standard bricks by the head section of vacuum brick extruder can not meet the technical requirements and needs to be stopped for replacement. The ultra-high carbon chromium nickel molybdenum niobium alloy spiral extruder developed by our company has a high hard carbide content of more than 40%. The matrix is martensite, and the metallographic structure is uniform. The high hardness alloy carbide can effectively resist the grinding of materials, and the service life is increased by more than 50% compared with the traditional Cr26 spiral extruder. According to the customer's raw material characteristics, the angle and pitch of the auxiliary blade are adjusted to effectively ensure the extrusion pressure and speed. It is an ideal matching product of high-efficiency vacuum extruder.
