Abstract

The invention discloses a resistance furnace for silicon carbide micro powder production and a using method thereof in the technical field of silicon carbide production. The resistance furnace comprises a furnace wall plate and a furnace bottom support; a supporting base is fixed to the bottom end of a reinforced concrete frame, the supporting base is symmetrically connected with screws in a threaded mode, the two screws are rotationally connected with a plane through supporting blocks, and the two screws are in transmission connection; the right end of one screw is connected with a first motor, an air suction hood, a purification box and a fan are arranged above the furnace wall plate, the air suction hood is in communication with the purification box, and the purification box is in communication with the fan. According to the resistance furnace for silicon carbide micro powder production and the using method thereof, a heat insulation layer, the concrete frame and a refractory bricklayer are detachably mounted at one end of the furnace wall plate, so that the refractory brick layer is convenient to replace, and the furnace wall plate and the resistance furnace can be prevented from being damaged; the air suction hood, the purification box, the fan and the like are added, the fan is started, harmful gas is absorbed into the purification box, harmful components in the gas areabsorbed by purification liquid when passing through a filter screen, the harmful gas can be well purified and discharged, and environment protection is facilitated.

Description

technical field [0001] The invention relates to the technical field of silicon carbide production, in particular to a resistance furnace for silicon carbide micropowder production. Background technique [0002] Silicon carbide, also known as moissanite and corundum, is an inorganic substance with a chemical formula of SiC. It is smelted through a resistance furnace with raw materials such as quartz sand, petroleum coke (or coal coke), wood chips (salt is required to produce green silicon carbide), etc. made. Silicon carbide also exists in nature as a rare mineral, moissanite. Among the non-oxide high-tech refractory raw materials such as C, N, B, etc., silicon carbide is the most widely used and economical one, which can be called corundum or refractory sand. Silicon carbide industrially produced in China is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals, with a specific gravity of 3.20-3.25 and a microhardness of 2840-33...
