The invention discloses a corundum mullite brick for a high-temperature high sulfur petroleum coke calcining furnace, belonging to the technical field of high-temperature calcining equipment. The corundum mullite brick comprises a surface enamel layer and an internal brick body, and is characterized in that the brick body is prepared by taking mullite as particle materials and taking mullite powder, fused white corundum powder, andalusite, sillimanite and Suzhou clays as fine powder materials; modified alpha-aluminum oxide powder is added, and the total mass ratio of the particle materials to the fine powder materials is 25-45 to 22-54. A high-temperature stable crystalline phase in the internal structure of the brick body comprises mullite (3Al2O3.2SiO2) and corundum; a working surface at whichthe brick is in direct contact with petroleum is coated with a special high-temperature glaze with high abrasion resistance and high corrosion resistance, and a dense permeable layerof the glaze on the surface of the brick body reaches about 5mm. According to the brick body structure, the erosion resistance capability of the high sulfur petroleum coke on a tank type calcining furnace in the high-temperature calcining process is improved, and the abrasion capability of the tank body in the high sulfur petroleum coke calcining process is improved at the same time.

The invention discloses a preparation process of enamel graphite cookware. The preparation process comprises the following steps: (1) processing graphite into a graphite cookware green body; (2), coating a binder on the surface of the graphite cookware green body uniformly, and then performing high temperature sintering so as to form an intermediate bonding layer on the surface of the graphite cookware green body; and (3), enameling the surface of the intermediate bonding layer so as to obtain the enamel graphite cookware, wherein the binder in the step (2) is a mixed solution which is obtained through uniform mixing of titanium powder or silicon powder or mixed powder of titanium powder and silicon powder, high-purity alcohol, phenolic resin and graphite powder at a mass ratio of 3:4:2:1.The enameling process is applied to the graphite cookware, an enamel layer is formed on the surface of the graphite cookware, and the surface strength of the graphite cookware is improved, so that asurface protective layer is formed, and damage of metal cookware to the graphite cookware is avoided during cooking.
