Production technique for preparing architectural ornament phosphorus slag cast stone by employing high-temperature phosphorus slag liquid

Abstract

The invention relates to a technique for the preparation of phosphorus dregs cast stone used for construction decoration and using high temperature phosphorus dregs fluid. The invention is characterized in that: firstly, the configuration and the preheating of auxiliary raw material: quartz sand and kaoline are taken as auxiliary raw materials and heated to 1,300-1,450 DEG C; secondly, hot ingredient: the high-temperature phosphorous dregs fluid, which is discharged from a phosphorus electric stove, passes a fluid groove and flows into a pond kiln, and the auxiliary raw material is put into a pond kiln simultaneously, wherein, the quality ratio of the phosphorus dregs to the auxiliary raw material is 65-75:25-35; thirdly, melting: the melting mix of the phosphorous dregs and the auxiliary raw material reaches 1,450-1,580 DEG C; fourthly, shaping; last, crystallization and annealing: the crystallization is processed under 1,000-1,150 DEG C for 60-120 minutes, and then is annealed to room temperature, thus a product is made. The invention can effectively use the thermal energy of the high-temperature phosphorous dregs fluid to realize the conversion of the phosphorous dregs fluid into the resources and reduce the energy consumption and the cost of cast stone production, thereby causing the phosphorous dregs cast stone adaptive to the purpose of large-scale construction decoration.

Description

technical field [0001] The invention relates to a production process for preparing phosphorous slag cast stone for architectural decoration by utilizing high-temperature phosphorus slag liquid, and the phosphorous slag cast stone product is mainly used in the field of architectural decoration. Background technique [0002] Using phosphate rock as raw material, yellow phosphorus is produced by electric furnace method, and CaO and SiO are discharged 2 The high-temperature melt whose main component is above 1350°C is the high-temperature phosphorus slag liquid. If the high-temperature phosphorus slag liquid is cooled by water quenching to form slag, it is phosphorus slag, which is a kind of industrial solid waste. Usually, for every 1t of yellow phosphorus produced, 8-10t of phosphorus slag will be discharged. The current phosphorous slag recycling technology in my country is mainly to use water-quenched phosphorus slag to produce cement, and its dosage is usually not higher ...

Problems solved by technology

[0004] The current phosphorus slag recycling technology mainly uses quenched phosphorus slag, which has the disadvantage that the heat energy of the high-temperature phosphorus slag liquid cannot be used. At the same time, the preparation of active cast stone products mainly uses raw materials for batching and melting, and there is a problem of heating and melting Excessive energy consumption, high production cost, and not being suitable for large-scale use as architectural decoration materials, the purpose of the present invention is to provide a production process for preparing phosphorus slag cast stone for architectural decoration by using high-temperature phosphorus slag liquid. Using high-temperature phosphorus slag liquid to prepare phosphorous slag cast stone for architectural decoration, effectively utilizing the heat energy of high-temperature phosphorus slag liquid, realizing direct resource utilization of phosphorus slag liquid, and reducing energy consumption and production cost of cast stone production
