Embodiment Construction

[0019] Ferrochrome alloy slag, waste glass, limestone, soda ash and fluorite are used as raw materials, and the proportions are shown in Table 1. Melting at 1500°C-1550°C under normal pressure for 1-4 hours, and then heat-treating the prepared basic glass to synthesize a slag-like glass-ceramic material. X-ray diffraction analysis and SEM analysis were performed on the synthesized samples.

Abstract

The invention relates to the technical field of synthesis of inorganic nonmetal materials, and aims at providing a method for compounding pyroxene-type microcrystalline glass materials by means of solid waste such as ferrochrome slags and waste glass, limestone, sodium carbonate and fluorite. The raw materials used for compounding mainly adopt the solid waste, and the ferrochrome slags belong to waste with severe toxicity and need to be treated individually. The waste microcrystalline glass materials are compounded only by means of normal pressed sintering, all performances meet needs of industrial production, the problem that the environment is polluted due to the fact that a large amount of solid waste is stacked is solved, the compounded waste slag type microcrystalline glass materials can be applied to building decoration materials, the method for compounding the pyroxene-type microcrystalline glass materials by means of the solid waste such as the ferrochrome slags and the waste glass, the limestone, the sodium carbonate and the fluorite accords with the industrial policy of circular economy advocated by the nation, and higher economic value and environmental significance are achieved.

Description

technical field [0001] The invention relates to the technical field of synthesis of inorganic non-metallic materials, in particular to a method for synthesizing a glass-ceramic material by using solid waste (ferrochrome slag, waste glass), limestone, soda ash and fluorite as raw materials. Background technique [0002] In recent years, my country's stainless steel production has shown a rapid growth trend, and the demand for ferrochrome is also increasing. At the same time, the environmental pressure faced by ferrochrome alloy smelting enterprises is becoming increasingly urgent, especially the discharge of solid waste from ferrochrome alloy plants must meet the national environmental protection requirements. The solid waste in the ferrochrome alloy plant mainly comes from the slag and dust generated in the high temperature production process. Ferrochrome slag has high viscosity and high melting point, and the slag and iron cannot be completely separated. Generally speakin...
