Problems solved by technology

Although this solution can obtain glass-ceramics, since the waste glass of each manufacturer is usually less and can be digested by itself, it is difficult for the waste glass of a single manufacturer to support this technical solution, and because the waste glass composition of each manufacturer is different, it is difficult to control, so it cannot Purchase waste glass from other manufacturers for this technical solution, so the technical solution disclosed in CN105152536A cannot realize industrialized production

Abstract

The invention discloses a glass ceramic produced by all electric fused rolling process technique using ferrochrome slags as raw materials and the production method therefor. The chemical composition of the glass ceramic comprises 4% to 6% of sodium monoxide, 3% to 5% of aluminium sesquioxide, 54.5% to 60% of silicon dioxide, 0.5% to 1% of phosphorus pentoxide, 7% to 10% of potassium monoxide, 18% to 22% of calcium oxide, 1% to 2% of chromium sesquioxide and 3% to 5% of fluorine. The glass ceramic is produced by all electric fused rolling process technique. The product has compressive strength of 300 to Mpa, flexure strength of 60 to 90 Mpa, density of 2.6 to 2.7 gram per cubic centimeter, Mohs hardness of level 6 to level 7, water absorption rate less than 0.01%, and smooth finish of 90 to 98. The glass ceramic is resistant to both acid and alkali, and meets the national class A test standards of radioassay.

Description

technical field [0001] Embodiments of the present invention relate to building decoration materials, and more specifically, embodiments of the present invention relate to a glass-ceramic produced by using ferrochrome alloy waste slag as a raw material by an all-electric melting rolling process and a production method thereof. Background technique [0002] Glass-ceramic not only has the basic properties of glass, but also has the polycrystalline characteristics of ceramics. It combines the characteristics of glass and ceramics and becomes a unique new type of material. Because of its high mechanical strength, high hardness, good wear resistance, strong corrosion resistance, good chemical stability and thermal stability, and can adapt to harsh environments, it has developed rapidly in the world in recent years. In particular, the "Twelfth Five-Year New Material Industry Development Plan" announced by the Ministry of Industry and Information Technology in January 2012 included ...
