Problems solved by technology

Some researchers have also proposed methods to directly use molten slag to produce microcrystalline materials, but these methods are not easy to realize in actual production: (1) In actual production, the production of microcrystalline materials affects the uniformity of material properties of molten materials, There are high requirements for chemical composition and bubble rate; (2) The preparation of microcrystalline materials requires the addition of various auxiliary materials and precise proportioning; (3) The basic glass melt is nucleated in the process of making glass ceramics The process of crystallization and crystallization has strict requirements on the heating rate and temperature control in the kiln. In actual production, another group of furnaces and kilns need to be built to implement this process.
(4) The step of material molding adopts the traditional casting process, which makes it necessary to increase the subsequent deep processing procedures in order to obtain the required microcrystalline products, which greatly increases the production cost; (5) The whole process of preparing glass ceramics (Mixed melting-casting-annealing-nucleation-crystallization-annealing) takes nearly 10 hours, and each step is intermit

Abstract

The invention discloses a method for preparing common glass by means of molten-state yellow phosphorus slag and belongs to the field of material manufacturing. The glass material is obtained through material preparation, heat blending, mix-melting and float glass forming. By adopting the float glass process during forming, the defect of traditional calendering, sintering and casting processes that a product high in flatness and glossiness, permeable to light and transparent can not be directly produced is overcome, and the glass material excellent in performance and quality can be obtained; high cost caused by follow-up deep processing including milling, polishing and glossing is saved, expenses of the whole process are reduced, and remarkable economic benefits are realized.

Description

technical field [0001] The invention relates to the field of manufacturing flat glass materials (building materials), in particular to a method for preparing ordinary glass by using molten yellow phosphorus slag. Background technique [0002] The electric furnace method is a production process commonly used by domestic yellow phosphorus production enterprises. The main content of CaO and SiO produced in electric furnace smelting phosphorus 2 The high-temperature molten material is as high as 1400~1500℃. At present, the conventional way to deal with this molten yellow phosphorus slag is to directly water it to cool it into normal temperature granular phosphorus slag, which is yellow phosphorus slag. According to statistics, about 8-10t of yellow phosphorus slag will be produced for every 1t of yellow phosphorus produced. The high-temperature molten material usually flows out from the slag discharge port of the electric furnace and is in a high-temperature molten state. The ...
