Production of abrasion-proof ceramic composite mold steel plate with self-propagating method

Abstract

The invention relates to a manufacture technique for improving the wearing resistance of an extrusion forming mould material, and the manufacture technique can be applied to the industries such as a building material and a flame-proof material which need the extrusion forming mould. The manufacture technique aims to manufacture a ceramics iron and steel composite board, so as to improve the rigidity of the key place of the mould and strengthen the wearing resistance of the mould through cutting, inserting and welding the board to the extrusion mould. The manufacture technique mainly adopts the technical proposal that: with vibration and magnetic force, the separation problem of the thermit reaction liquid product of Fe and Al2O3 in self-spreading ceramics iron and steel composite manufacturing is solved, so as to reach the equal effect for separating the rotation inertia force. The main element of the mould comprises a flame-proof material box provided with the steel plate backing as the base, and reaction raw material Al as well as Fe2O3 mixed-powder which are filled-in at the upper opening of the flame-proof material box; one end of a steel mobile stage is fixedly provided with a speed-regulation vibration electric motor with eccentric quality, and the middle part of the steel mobile stage corresponding to the steel plate backing is punched with for fixing a permanent high magnet; the upper side of the magnet is parallel to the surface of a platform; the platform is connected with the base through a rolling bearing and a spring.

Description

Technical field: [0001] The invention belongs to the manufacturing technology for improving the wear resistance of extrusion molding die materials. It can be used in industries that require a large number of extrusion molds, such as building materials, refractory materials, and metal semi-solid processing. Background technique: [0002] The mold is the main production equipment in the extrusion molding of building material molding, refractory material molding, metal semi-solid processing and other industries. Their common feature is that the friction of the material against the mold is particularly large in the extrusion molding project, and the mold wears quickly. The precision of the mold is short and the service life is short. In order to solve this problem, experts and engineers have developed a variety of high-hardness, wear-resistant high-carbon, high-chromium, high-manganese, high-molybdenum and other alloy steels as mold manufacturing materials, or for existing alloy...

[0007] Static self-propagating method to prepare ceramic coating dies for semi-solid processing of ferrous metals (Chen Wei et al., application number: 200510040328.7; approval announcement number: 1762618), which has been applied in the production of extrusion dies, and its characteristic is that the die is integrally formed at one time , but the literature only finds examples of successful circular dies with simple shapes, and it is still very difficult to produce extrusion dies with slightly complicated shapes. Furthermore, the process of preparing extrusion-molded ceramic coating dies The technical difficulty is relatively large, and it is difficult to popularize in general extrusion die manufacturers
