Abstract

The invention discloses a high-wear-resistance iron boride alloy screw element for a double-screw machine. The iron boride alloy screw element comprises a body and an iron boride alloy layer; the iron boride alloy layer is evenly concentrically molten on the surface layer of the body, the overall thickness of the iron boride alloy layer is 50-150mum; the body is made of high-chromium high-carbon die steel which is Cr12MoV. The high-wear-resistance iron boride alloy screw element for the double-screw machine, disclosed by the invention, is used in industries of plastics, LED (Light-emitting Diode)s, cables, food, feeds, construction materials and the like, and the iron boride alloy screw element has a high wear resistance property, and is capable of greatly lowering the manufacture cost and application cost and greatly improving the production efficiency.

Description

Technical field [0001] The invention relates to an iron boride alloy screw element for a twin-screw extruder (granulation) machine; in particular, it relates to a high wear-resistant iron boride alloy screw element for a twin-screw machine manufactured by using mechanical processing and surface material modification technology and the same Production method. Background technique [0002] With the rapid development of my country's plastics industry, LED industry, cable industry, food industry, feed industry, and building materials industry, these industries are equipped with a large number of twin-screw extruders, which greatly changed the single-screw machine crushing and low conveying efficiency, Defects such as poor mixing uniformity and low productivity; [0003] However, with the continuous upgrading of twin-screw machines, such as the speed of the machine increased from 400 rpm to 800-1000 rpm, a large amount of high-wear filling such as glass fiber, ceramics, resin, nylon, an...
