Tin tank bottom brick

Abstract

The invention discloses a tin tank bottom brick. The problems of easy spalling and upward floating of reaction layers of tin tank bottom bricks are solved in the invention. The tin tank bottom brick comprises a main material and an additive, wherein the main material comprises, by weight, 45-55 parts of Al2O3, 35-40 parts of SiO2, 15-20 parts of CaO, and 0.1-0.3 parts of a water reducer; and the additive comprises, by weight, 1-1.5 parts of R2O, 1.4-1.6 parts of Fe2O3 and 1.2-1.5 parts of ZrO2.

Description

technical field [0001] The invention relates to a tin bath bottom brick. technical background [0002] The bottom brick of the tin bath is a special refractory material used to build the inner lining of the tin bath. Since the bottom brick will form silicate glass during high temperature sintering, the Na 2 O penetrates into the pores of the bottom brick and reacts to form nepheline minerals, which causes the volume expansion of the tin bath bottom brick by about 20%, resulting in the peeling and floating of the reaction layer. Contents of the invention [0003] The technical problem solved by the invention provides a tin bath bottom brick, which solves the problem that the reaction layer of the tin bath bottom brick is easy to peel off and float up. [0004] A tin bath bottom brick, comprising main ingredients and additives, the main ingredients include the following components and the parts by weight of each component are: [0005] [0006] The additive comprises th...
