Problems solved by technology

In contrast, the laser heating is too concentrated, and the results of the heat and chills are heavily dependent on the matching degree of the material and the base material. Generally, there are two problems that are most likely to occur: on thin plate products with low strength and good plasticity, the thickness is less than that of the molten metal. Materials with a relatively high expansion coefficient, such as the cladding treatment on medium and low carbon steel, often cause warping and deformation of the product; the base material has high strength and poor deformation ability, especially those with poor thermal conductivity, which are easy to be cladding after treatment. Transverse cracks in the layer, sometimes vertical cracks on the substrate side of the edge of the cladding strip

Abstract

The invention discloses a roller surface strengthening material and a roller surface composite strengthening method of a double-roller crusher, and relates to the technical field of metal surface engineering. The roller surface composite strengthening method includes the following steps: (1) grinding and cleaning the roller surface Processing; (2) configure laser cladding powder, lay laser cladding powder on the roller surface, and prepare laser cladding layer through laser cladding operation; (3) wait for the roller surface of the double roller crusher to cool to room temperature Then preheat; (4) configure the spray welding powder, lay the spray welding powder on the roller surface, and prepare the spray welding layer through the spray welding operation. The invention significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the surface of the base material, improves the hardness of the roller surface, prolongs the service life of the rollers of the double roller crusher, and reduces the manufacturing cost.

Description

Technical field [0001] The present invention relates to the field of metal surface engineering, in particular, a two-roller crusher pressure roll roll surface reinforcing material and a roll surface composite strengthening method. Background technique [0002] The double roller crusher is mainly used in the mineralization of ore, the roller surface shape can be divided into a light roller, a crude tooth roller, or the like, which can be adjusted according to the size required by the material, suitable for sintering, coal, cement, silicate , Glass, ceramics, refractory materials, etc., suitable for crushing of brittle materials. In the actual production, when a high hardness is high, such as a large amount of 88 aluminum is required in the production of refractory materials, the size of the upper block size is approximately 35 mm, and the size is approximately 3 to 5 mm after crushing. The hardness of this material is very high. It is found that it is necessary to break the alumin...
