Problems solved by technology
However, due to the high hardness and poor grindability of water slag, at present, only a small amount of water slag is used as cement admixture by cement production enterprises, while most steel mills pile up water slag as waste
Therefore, the scope of water slag being used as the main raw material is extremely low, and at the same time, it has caused a certain degree of environmental pollution to land, rivers, etc.

[0041] 2. Send the above-mentioned mixture into an all-electric melting furnace for melting. The melting temperature is 1450°C. After clarification and homogenization, the melted glass enters the forehearth through the liquid flow hole and the ascending channel, and the temperature drops to 1250°C before entering the calendering process. The working pool enters the annealing kiln after being calendered and formed by a calender (forming temperature 1050°C).
[0042] 3. Anneal the rolled glass plate annealing kiln. The temperature of entering the kiln is 650°C. After holding at 650°C for 15 minutes, cool down to 580°C at a rate of 3°C / min, and then cool down to 300°C at a rate of 9°C / min. ℃, and then cooled to ...

Abstract
The invention discloses a method for producing microcrystal glass by utilizing water slag as a main raw material. The method comprises the following steps: step 1, raw material selection; step 2, rawmaterial mixing; step 3, mixture melting; step 4, calendaring molding; step 5, annealing; step 6, crystallization. The method disclosed by the invention has the benefits that as the water slag adoptedis obtained by water quenching from blast furnace molten slag, the melting quality of the water slag is excellent, and the required melting temperature is relatively low, so that the energy consumption is reduced; the raw material cost can be greatly reduced; as the water slag contains more oxides required for the composition of the microcrystal glass, less types of raw materials are added, and the production is convenient and easy to control; as the water slag contains or does not contain a very small amount of colored ions, the white microcrystal glass can be prepared; as multiple colorantscan also be added, red and grey microcrystal glasses and other colors of microcrystal glasses are prepared, and the color is stable and easy to control.
Description
technical field [0001] The invention relates to a method for preparing glass-ceramics, in particular to a method for producing glass-ceramics by using water slag as the main raw material. Background technique [0002] Slag glass-ceramic is made of metallurgical slag, tailings and other industrial waste slag and natural minerals as the main raw materials, introducing a certain amount of crystal nucleus agent, flux and other auxiliary raw materials, and is made through batching, melting, forming, annealing, crystallization and other processes a microcrystalline material. With the acceleration of my country's industrialization process, various slags and tailings are discharged and accumulated in large quantities, causing extremely serious environmental problems. [0003] At present, most glass-ceramics on the market use natural minerals or pure chemical substances as the main raw materials, which have high production costs and low raw material reserves, while slag glass-cerami...
