Abstract

The invention relates to a graphitization furnace and a manufacturing method thereof. The graphitization furnace comprises conductive walls, furnace core plates, carbon blocks and thermal insulation material layers; when the graphitization furnace is manufactured, a furnace core area is calculated firstly; the two conductive walls which are opposite left and right are constructed according to the furnace core area obtained through calculation, and the peripheries of the conductive walls are covered with the carbon blocks; the furnace core plates are arranged on two sides of the conductive walls in a surrounding manner, and width of the defined furnace core is the same as that of the conductive walls; finally, the thermal insulation material layers are additionally arranged on outer sides of the carbon blocks and the furnace core plates. Resistance value of the carbon blocks is larger, so that current can be effectively prevented from being diffused outwards; besides, the width of the furnace core is the same as that of the conductive walls, the thermal insulation material layers are made of a thermal insulation material with larger resistance value, therefore, current can be further prevented from being diffused, the furnace temperature is increased, and the phenomenon of arc strike oxidation of a crucible in the furnace is eliminated.

Description

technical field [0001] The invention relates to the technical field of graphitization furnaces, in particular to a graphitization furnace and a manufacturing method thereof. Background technique [0002] The Acheson graphitization furnace was rebuilt on the basis of the silicon carbide resistance furnace at the end of the 19th century. Its main feature is that the raw material of the negative electrode material and the resistance material (coke particles) put into the furnace together constitute the furnace resistance, and 2000 The high temperature of ~3000°C graphitizes the negative electrode material raw material. The principle of Acheson graphitization furnace is to make the resistance material generate a lot of heat energy through the current flowing through the resistance material in the furnace (usually the resistance material needs to reach a high temperature of about 3000 degrees), and then transfer the heat energy to the product, and finally realize the graphitizati...
