The medium temperature layer is wrapped on the outer wall of the high temperature layer, and the high temperature layer is wrapped on the outer wall of the working layer; The installation end of the furnace cover is fixed on the upper top of the high temperature layer and the working layer, the furnace cover is connected with the furnace top ring flue through a pipeline, the furnace top ring flue is fixed on the upper top of the thermal insulation layer and the middle temperature layer, the furnace top ring flue and the furnace cover constitute a top insulation area; The technology realizes rapid heating, can effectively reduce power consumption, reduce the volatilization of dust and smoke, and improve the technical problems of the working environment.

The invention relates to a packing material for sealing the negative electrode of a high temperature graphitization furnace and its formulation technology

Introduction: The technology provides a filler for high temperature graphitization furnace negative electrode seal, the technology uses the characteristics of clay, bentonite, and ultrafine powder to ensure that the sealing filler can be easy to construction, the filler added silicon carbide, carbon black or graphite and other antioxidant components, can be prefered to react with the air to ensure that the electrode negative electrode is not oxidized by the air. In addition, the reaction characteristics of kyanite, andalusite, quartz, MgO and other components in the filler at high temperature ensure the high temperature expansion performance of the filler, blocking the air passage, thus extending the service life of the negative electrode. Therefore, the sealing filler can improve the service life of high temperature graphitization furnace.

3 A combined graphitization furnace head and tail structure and construction method thereof

Brief introduction: The technology provides a combined graphitization furnace head and tail structure and its construction method. The top of the furnace head or tail electrode is provided with an open trench structure, which is used for the installation of the furnace head or tail electrode and the surrounding carbon slide. On the top of the electrode groove, the prefabricated concrete pressure beam with a lifting lug device is used to seal the electrode on the entire furnace head and tail. The movable concrete compression beam is of the same material as the concrete exterior wall of the fixed furnace head and furnace tail. The technology fundamentally solves the common technical problem of inconvenient operation in the installation and maintenance of the external wall structure of the integral head and tail of the graphitization furnace, which is of great significance for reducing the labor intensity of workers and improving the installation efficiency and production efficiency of the furnace
