Abstract

The invention provides a tank skin brick with excellent heat-conducting property for a petroleum coke calcining furnace and a preparation method of the tank skin brick. The tank skin brick contains the following raw material components: silicon carbide powder, calamine, red clay, kaolin and silicon nitride, and further contains the following raw material components: titanium dioxide, graphene, far-infrared ceramic powder, quartz, barium triphosphate and spessartite. The titanium dioxide is prepared by mixing three types of titanium dioxide such as R-706, R-248 and R-103 according to a mass ratio of 1:1:3. The tank skin brick with excellent heat-conducting property for petroleum coke calcining furnace, disclosed by the invention, has excellent heat-conducting property at a high temperature,and the production energy consumption is greatly reduced.

Description

technical field [0001] The invention relates to a tank wall brick for a petroleum coke calcination furnace, in particular to a tank wall brick for a petroleum coke calcination furnace with good thermal conductivity and a preparation method thereof. Background technique [0002] The tank side wall of the tank calciner adopts special tank wall bricks, and the outside of the tank wall brick wall is a multi-layer flue heating system. The material is heated in a sealed and air-isolated state in the tank, with small burning loss and stable quality. [0003] Traditional tank wall bricks mainly use silica bricks. The main raw materials of silica bricks are tridymite and cristobalite, and there are also a small amount of quartz and glass. With the development of the times, the quality requirements for tank wall bricks in this field are getting higher and higher; especially the service life and thermal conductivity. At present, the existing tank wall bricks on the market are often p...
