Abstract

The invention discloses a pyrophyllite-silicon carbide carbon brick for ladles which is prepared by the following raw materials by weight: 30-60 parts of pyrophyllite with a particle size of 5-30 mm, 20-30 parts of pyrophyllite powder with a particle size of 120-180 meshes, 10-20 parts of silicon carbide with a particle size of 120-320 meshes, 5-15 parts of -199# graphite, and 5-10 parts of phenolic resins. The invention adopts pyrophyllite and silicon carbide as main raw materials, and the produced unburned ladle lining brick can resist high temperatures of above 1500 DEG C, has good integrity, good brick joints, good heat stability, and strong molten iron erosion resistance, has a service life of over 800 times for ladles of above 120 T; because the pyrophyllite is cheap but good in quality, the whole product has low cost, good economic benefit, and less consumption of iron-resistant materials per ton.

Description

technical field [0001] The invention relates to a lining rotor for a ladle, in particular to a pyrophyllite-silicon carbide carbon brick and a preparation method thereof. Background technique [0002] Ladle lining bricks have high requirements, and silicon carbide carbon bricks are generally used. Silicon carbide carbon bricks not only need to be sintered, but also cost high. Contents of the invention [0003] The technical problem to be solved by the present invention is that the silicon carbide carbon brick not only needs to be sintered, but also has high cost, and provides a pyrophyllite-silicon carbide carbon brick and a preparation method thereof. [0004] The technical scheme of the present invention is: a kind of pyrophyllite-silicon carbide carbon brick for ladle, it is made of the raw material of following parts by weight: [0005] Pyrophyllite with a particle size of 5-0 mm 30-60 [0006] Pyrophyllite powder with a particle size of 120-180 mesh 20-30 [0007] ...
