Abstract

The invention discloses a preparation process for producing mineral wool from solid waste silicon-manganese slag. The preparation process comprises the following steps: S1, preparation of a hardening and tempering material: selecting a proper amount of nepheline and fly ash, and adding the nepheline and the fly ash into a high-speed stirrer for stirring treatment to obtain the hardening and tempering material; S2, mixing treatment: feeding the silicon-manganese slag into a feeding tank through a slag channel, adding the tempering material in the step S1 into the feeding tank, and fully and uniformly mixing all the components; and S3, feeding the mixture prepared in the step S2 into a slag furnace for treatment to obtain a high-temperature solution, and adding the high-temperature solution to a roller in a centrifugal machine to form raw wool. The preparation process is good in practicability, energy consumption is reduced, the technological process is simple, the qualification rate of the mineral wool can be increased, and meanwhile the attractiveness of the prepared mineral wool can be improved.

Description

technical field [0001] The invention relates to the technical field of mineral wool preparation, in particular to a preparation process for producing mineral wool from solid waste silicomanganese slag. Background technique [0002] With the rapid development of the global economy, the problem of energy shortage is becoming more and more serious, and the technology of energy saving and emission reduction has become a research hotspot all over the world. At present, my country's energy situation is severe, and the product energy consumption index is too high. The energy consumption per unit of the main energy-consuming products is 25-90% higher than that of developed countries (the weighted average is about 40% higher); secondly, the energy consumption of the output value is high. Energy consumption is one of the highest in the world. For example, for every kilogram of oil equivalent of energy, Japanese companies can create an average output value of 10.2 US dollars, while Chin...
