Abstract

The invention relates to an MgO-SiC-C material synthesized by forsterite and C and a method for making the same. The method adopts the following technical proposal that: according to molar ratio, 1 to 4 mol of forsterite mineral powder and 3 to 6 mol of C powder are mixed, and a bonding agent occupying 4 to 10 percent of the mass percentage content of the mixed materials is added; the mixture is stirred or ground for 10 to 30 minutes, and is dried after press forming; then, sintering is carried out under a reducing atmosphere at a temperature of between 1,450 and 1,700 DEG C with the heat preservation time of between 2 and 8 hours, thereby obtaining an MgO-SiC-C composite material. The industrial carbon powder raw material adopted by the method has wide sources, and the forsterite mine has abundant resources, thereby not only effectively solving the problem of magnesia resource shortage, but also having low production cost; moreover, the made MgO-SiC-C composite material can maintain excellent properties and reduce corrosion wear, thereby prolonging service life.

Description

technical field

[0001] The present invention belongs to forsterite (2MgO·SiO 2 ), industrial carbon powder (C) as the composite material field of base material, especially relate to a kind of MgO-SiC-C material synthesized with forsterite and C and its preparation method. Background technique

[0002] MgO-SiC-C composite materials have excellent high temperature resistance and thermal stability, can be used in non-ferrous metals and iron and steel smelting equipment, and can also be prepared into high-quality high temperature resistant heat insulation materials and wall materials for high temperature kilns, especially It is suitable for the ladle lining and refining furnace lining of clean steel such as low carbon steel and ultra-low carbon steel, replacing MgO-C material, which is beneficial to the quality of steel and has a good use effect.

[0003] The existing production and preparation method of MgO-SiC-C composite material is to use magnesia and industrial SiC as the ...
