Movable silicon carbide smelting furnace

Abstract

The invention relates to a movable carborundum smelting furnace. The movable carborundum smelting furnace comprises a furnace vehicle, a gas collecting tank and a track, wherein longitudinal bearing beams are arranged in a furnace vehicle chassis; bearing seats on the two sides of vehicle wheels are fixed to the bearing beams through bolts; insulation sleeves are arranged outside studs in a sleeving mode; insulation mats are arranged between the bearing seats and the bearing beams; and insulation mats are also arranged between gaskets and the bearing beam as well as between the gaskets and the bearing seats; each side seam is divided into a left part and a right part, wherein a side seam insulation mat is arranged between each left half part and each right half part, the shape of each side seam insulation mat is the same as the cross-sectional shape of each side seam; the left half parts and the right half parts are connected through bolts;, insulation sleeves are arranged outside studs in the sleeving mode; the insulation mats are also arranged between the spacers and the left half parts as well as between the spacers and the right half parts; and plugging board doors are arranged at the lower parts of the side seams. According to the movable carborundum smelting furnace disclosed by the invention, an insulation structure is designed, so that the problem of large electric loss of the movable carborundum smelting furnace is solved; the plugging board doors are designed on the lower parts of the side seams, so that the problems that the opening degree of a conventional lower discharge door is difficult to control, materials are liable to leak, and the smelting furnace is greatly affected due to heating deformation are solved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of silicon carbide smelting, in particular to a movable silicon carbide smelting furnace. [0003] Background technique: [0004] Silicon carbide is also called emery or refractory sand. The molecular formula is SiC, its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum. It has high temperature resistance, wear resistance, thermal shock resistance, chemical corrosion resistance, radiation resistance and good electrical and thermal conductivity. In addition, it is widely used in metallurgy, chemical industry, ceramics, aerospace and other fields. Industrial silicon carbide was successfully developed in 1891 and is the earliest artificial abrasive. Although a small amount of silicon carbide exists in meteorites and the earth's crust, so far no mineable sources have been found. [0005] The industrial production of artificial silicon carbide has a hi...

Problems solved by technology

This structure has the following disadvantages: 1. The opening is not easy to control, because the hinge is used, and the corner is difficult to control under a large amount of material; 2. The production is complicated and requires high precision. 3. Due to the high reaction temperature of the silicon carbide smelting furnace, it is easy to be deformed by heat, and it is difficult to ensure dimensional stability
