High-titanium blast furnace slag microcrystalline stone material and preparation method thereof

Abstract

The invention belongs to the field of a stone material manufacturing process and particularly relates to a high-titanium blast furnace slag microcrystalline stone material and a preparation method thereof. Aiming at the problems that an existing microcrystalline stone material prepared from blast furnace slag has poor flatness, rough surface, poor appearance and the like, the invention provides the high-titanium blast furnace slag microcrystalline stone material and the preparation method thereof. The preparation method comprises the following steps: mixing 40-60 parts of high-titanium blast furnace slag, 24-37 parts of a stabilizer, 5-8 parts of a fluxing agent, 5-8 parts of a nucleating agent, 2-4 parts of a crystallization accelerant, 1-3 parts of a color modifier and 1-2 parts of a reducing agent; smelting at 1480 DEG C-1530 DEG C, homogenizing and clarifying to obtain a mixed melt; and calendering to form a sheet material, and nucleating and crystallizing to obtain the microcrystalline stone material. According to the method provided by the invention, the glass viscosity can be reduced; stable molding of glass is accelerated and the chemical stability of the glass is improved; the prepared microcrystalline stone material has a smooth and flat surface, pure color and luster and good quality. The preparation method provided by the invention is simple to operate and the requirements on equipment are not high, so that the preparation method is convenient to popularize and apply.

Description

technical field

[0001] The invention belongs to the field of stone manufacturing technology, and in particular relates to a high-titanium blast furnace slag microcrystalline stone and a preparation method thereof. Background technique

[0002] Microcrystalline stone is a unique new type of inorganic non-metallic material. Microcrystalline stone has many excellent properties, such as high mechanical strength, good chemical stability and thermal stability, wear resistance, corrosion resistance, etc. And get widely used.

[0003] Blast furnace slag is a kind of waste slag discharged from the blast furnace when smelting pig iron. It belongs to silicate material. main ingreadient.

[0004] However, for the waste slag after blast furnace smelting of vanadium-titanium magnetite, that is, high-titanium blast furnace slag, because it contains a large amount of titanium oxide, the titanium content is as high as more than 20%. As we all know, titanium oxide is a commonly used cryst...
