Abstract

The invention discloses a glass ceramic board for industrial protection and a preparation method thereof. The preparation method comprises the following steps: 1) preparing raw materials according to requirements of the system CaO-MgO-Al2O3-SiO2 and allowing the raw materials to comprise the basic compound components consisting of, by weight, 50 to 55% of SiO2, 8 to 10% of MgO, 12 to 14% of CaO, 8 to 10% of Al2O3, 3 to 5% of FeO, 2 to 4% of Na2O and K2O, 6 to 8% of CaF2 and 3% of TiO2; 2) uniformly mixing the raw materials and carrying out melting and homogenization so as to obtain glass liquid; 3) subjecting the glass liquid to continuous calendering molding and annealing; 4) directly sending an annealed glass plate to a nucleation and crystallization furnace on line for nucleation and crystallization; and 5) and subjecting a glass ceramic plate having undergone nucleation and crystallization to on-line cutting and cooling to room temperature so as to obtain the glass ceramic board for industrial protection.

Description

technical field [0001] The invention relates to the technical field of industrial protective materials, in particular to a wear-resistant and corrosion-resistant glass ceramic plate and a preparation method thereof. Background technique [0002] Iron and steel, coal, electric power, chemical industry, papermaking, building materials and other industries are the pillar industries of our country. The transportation and storage of raw materials and products in these industries require protection of related equipment and devices. For example, blast furnace mixing bins, sintering bins, feeders, ball machines, etc. in the iron and steel industry; gangue bins, medium barrels, scraper machines, bucket elevators, chutes, and under-screen funnels in the coal industry need to add a layer Wear-resistant linings; coal unloading trenches, coal hoppers, furnace front bins, dry coal grids, dumpers, slag extractors, water treatment, etc. in the power generation industry; anti-corrosion groun...
