Plastic Machine Bimetallic Parallel Twin Screw Barrel and Liner for Extruder Machine

Product Description

Main Materials: NiCrW alloy (Ni60 based on the addition of CrC and CrB)
Main Features: Wear resistance, corrosion resistance, belongs to the special alloy, hardness in HRC≥57, alloy parent full melt, improve the density, hardness.
Material Parameters Temperature Resistance: Temperature limit 600ºC Alloy Layer Thickness: >=1.8mm Alloy Layer Hardness: 57-64HRC The Main Process Is Different (from the original sintering process to the current spray welding process) The product has better densification, the hardness can reach more than 57 degrees, and the service life of the product is 3-5 times that of the sintering process.
Properties of Nickel-Chromium-Tungsten Alloy Nickel-Chromium- Tungsten alloy has excellent abrasion resistance and corrosion resistance. The increase of Cr content in the nickel-chromium alloy matrix contributes to the oxidation resistance, high temperature resistance and corrosion resistance of the alloy. At the same time, the addition of CrB is better than WC. The microhardness of CrB is as high as 4000-4200DPH, which is close to diamond. It is more conducive to improving the overall strength of the alloy. Due to the high density of WC, it is about 15.7g/cm3, while the matrix of nickel-chromium alloy is only about 8g/cm3. The melting is caused by the uneven surface and depth of the alloy due to the easy segregation of WC, so the content and particle size of WC must be controlled.
Nickel-Chromium-Tungsten alloy( we call OS 02H) hard phase increased to about 50%, OS02 is only ten to thirty,Moreover, the fusion is not sufficient, and the microscopic pores are relatively obvious, which is reflected by the Rockwell hardness HRC of only 52-55.While the Rockwell hardness of nickel chromium tungsten alloy (OS02H) is HRC56-64, the conventional control is HRC58-60. The service life is 3-5 times longer then WR5 or CPM10V.
Nickel-Chromium-Tungsten alloy( OS02H )on the basis of Ni60 in accordance with foreign twin screw working conditions of the formula, greatly improved Hard phase carbides (containing tungsten carbide chromium carbide and other carbides), and the nickel pool fullDissolve. Our Ni-Cr -W alloy layer can reach HRC64 is the best proof.
Our Advantage 1 1) Independent research and development of materials and processes can ensure the performance and process of materials to the maximum extent, and greatly prolong the service life compared with ordinary products.
Own raw material sintering furnace Heat treatment of self-contained Screw Elelments Vacuum heat treatmented furnace Our Advantage 2 2) Independently develop the process of key products, and constantly improve and enhance the old process to achieve the best product performance.
The liner alloy layer -- old sintering process Characteristics and advantages of the new spray welding process:
the product is better in dense, the hardness can reach more than 56 degrees, the service life of the product is 3-5 times that of the sintering process, low cost, less waste. Our Advantage 3 3) Continuously improving and optimizing product appearance of the composite layer ,which greatly improved the service life of products.

The original inner wall is a thin 8 - older sinering process Now the ellipse flat Angle process -New Spray Welding Process. Company Profile
