Abstract
The invention relates to a cladding type threaded component for a parallel double-screw extruder and a manufacturing method thereof. The cladding type threaded component for the parallel double-screw extruder comprises a main body and a nickel-based tungsten carbide spray welding layer, wherein the nickel-based tungsten carbide spray welding layer is uniformly and concentrically melted on the outer surface of the main body. The method for manufacturing the melt type threaded component for the parallel double-screw extruder comprises a billet steel cast process, a spray welding process, a cladding process and a machining process. The cladding type threaded component for the parallel double-screw extruder has the advantages of mechanical property meeting technical specification and property requirements of the parallel double-screw extruder, wear resistance and corrosion resistance more excellent than the properties of domestic top-level high-speed tool steel, low manufacturing cost, reliable structure, advanced process, high cost performance, remarkable social and economic benefits and wide popularization and application value.
Description
【Technical field】 [0001] The invention relates to a fusion-type thread element and a manufacturing method thereof, in particular to a fusion-type thread element for a parallel twin-screw extruder used in the spray welding, melting and machining industries and a manufacturing method thereof. 【Background technique】 [0002] With the development of my country's plastics industry, cable industry, building materials industry and feed industry, after a large number of parallel twin-screw extruders are used, the crushing of single-screw extruders has been greatly changed, with low conveying efficiency, poor mixing uniformity, and low production capacity. advanced defects. [0003] However, due to the continuous upgrading of parallel twin-screw extruders (increasing speed), and the need to use a large number of high-wear materials such as nylon, glass fiber, and calcium carbonate in applications, thread elements for parallel twin-screw extruders The wear and corrosion resistance of ...
