Abstract

A high-temperature heating vacuum furnace for carbonization catalysis and graphitization purification comprises a furnace body, a furnace door, a bracket, a lifting device, a burner, and a draught fan; the furnace body is provided with a high-strength castable material, a refractory brick and a fiber board from inside to outside. The high-temperature heating vacuum furnace is characterized in that the bracket is provided with sliding rails; the furnace door moves up and down along the sliding rails under the action of an electric hoist. According to the high-temperature heating vacuum furnace, a real-time data feedback system and a precise temperature control system are added, the problems of temperature precision control and homogenization heating in a heating process and a cooling process are solved, material internal heating uniformity is achieved, the appearance material is smooth, no granular crystals, holes or other defects exist, a large-size graphite film with the size of 1000 mm*200 mm can be produced, and the A grade rate is more than 98%.

Description

technical field [0001] The invention relates to a high-temperature heating vacuum furnace for carbonization catalysis and graphitization purification. Cooling environment. Background technique [0002] In the heat dissipation market of information products, the production of high-end graphite high thermal conductivity film is mainly monopolized by multinational companies such as Panasonic; due to performance and quality reasons, domestic graphite high thermal conductivity film can only occupy the primary market, and it is even difficult to provide customers with a whole sheet of A-grade graphite high Thermally conductive film. Through the product skeleton structure, raw material research and control, special catalyst, high and low temperature treatment, product application research and innovation, etc., the project can mass-produce the entire high-conductivity graphite film with large size, smooth surface, full range of thickness, and excellent thermal conductivity. The im...
