Filler for calcining carbon

Abstract

The invention relates to a plugging compound used for carbon backing and is characterized in that the plugging compound used for carbon baking is alumina or alumyte kernels, the granularity of which are less than 6mm. The invention directly takes alumina and alumyte as plugging compound, or takes alumina and alumyte as the main raw material. After being ground, dispensed, mixed, pelleted and baked, the composite particles are obtained. The Coefficient of heat conductivity of the new baked plugging compound is better than that of the traditional plugging compound; the adsorptivity of the new baked plugging compound is greatly reduced compared with that of the traditional plugging compound. The products are not stick to the materials and the baking quality can be greatly improved.

Description

A kind of filler for carbon roasting technical field The invention relates to a filler for carbon roasting. Background technique The roasting process of carbon products is a heat treatment process in the carbon industry. It is also a key process that determines product quality. During the roasting process of the product, along with a series of processes such as the softening of the product, the discharge of volatile matter, and the coking of the pitch, the volume density, true density, resistivity, porosity, strength, and oxidation resistance of the product will also occur accordingly. changing. During the roasting of carbon materials, the filler plays the role of isolating the air, preventing the oxidation of the product, and supporting it. At the same time, it also acts as a heat transfer medium responsible for transferring heat from the flue wall to the product, and forms a certain pressure atmosphere around the product. It is generally believed that the ideal fille...
