Abstract

The invention discloses a manufacturing method of a mixer blade, and the manufacturing method comprises the following steps of: manufacturing the base body of the mixer blade; selecting a laser cladding powder material; carrying out surface cleaning; carrying out laser cladding processing; and carrying out post heat treatment. The laser cladding powder material comprises the following chemical components in percentage by weight: 0.8%-1.2% of carbon, 0.2%-0.35% of silicon, 4.5%-6.0% of molybdenum, 3.0%-6.0% of chromium, 0.2%-0.4% of manganese, 1.5%-2.5% of vanadium, 5.5%-6.5% of tungsten and the balance of iron, and the powder size is 53-150 micrometers. The mixed blade manufactured through the method disclosed by the invention can achieve the cladding layer hardness more than HRC 60, is uniform in internal structure after being subjected to heat treatment, achieves the grain size from 10 level to 11 level, is excellent in property, achieves the abrasion resistance and the scouring resistance and can meet the requirements for using conditions of the mixer blade. According to the invention, the cladding layer is compact in internal structure, the porosity of the cladding layer is less than 0.5%, the geometric dilution ratio is about 10%, and the depth of a heat-affected area is less than 1 mm; the cladding layer is made of metal materials, so that the defect of easy breakage of an original ceramic material is overcome; and the cladding layer forms metallurgical bonding with the base body, so that the defects of poor bonding force and easy desquamation after an original hard alloy sheet is inlaid are overcome.

Description

technical field [0001] The invention belongs to the technical field of manufacturing and laser cladding of mixer blades, and in particular relates to a manufacturing method of mixer blades. Background technique [0002] The blade of the mixer is the main consumption part of the mixer, especially when mixing and stirring some ultra-hard granular powder, the consumption of the blade is extremely serious. [0003] The currently used mixer blades are as follows: [0004] 1. Pure ceramic material or ceramic material inlaid on the outside of ordinary steel base material. The actual use effect of this kind of mixer blade is not ideal, mainly due to the poor internal bonding force of the ceramics, and the poor impact resistance of the ceramic material itself, it is very easy to break during use; [0005] 2. Carbide sheets are inlaid on the outer surface of ordinary steel substrates. Although the hardness of the cemented carbide sheet inlaid on the top of this mixer blade is about...
