Problems solved by technology
[0003] The remaining slag after large-scale production also faces many problems: one is that the temperature is too high and needs to be transported away in time, and the other is that it is rich in iron and other rare earth components and needs to be recycled and refined
Therefore, some enterprises simply take away the waste residue and bury it, resulting in a waste of manpower and mineral resources.

[0021]
[0022] Mix the ingredients of Examples 1-5 according to the weight ratio, and after mixing evenly, quench in molten water at a high temperature of 1400° C. to form particles with a size of 0.5-5 mm. When the frit product is used, the particles cover the slag at a temperature of 1400°C, melt and penetrate into the slag and undergo a chemical reaction, and when the temperature of the slag drops to 600°C, it will solidify and agglomerate. When it is re-melted and purified, it only needs to be heated to 1000°C, and most of it will be melted, and a thorough chemical reaction will occur, which is beneficial to separation and purification. Heat conversion is realized and energy is saved.

Abstract
The invention relates to a low-temperature solid slag fused block and a preparation method thereof, belonging to the field of slag treatment. The low-temperature solid slag fused block comprises 80% of total content of ascharite, borocalcite, coarse whiting and albite and 20% of total content of pyrophyllite, petalite, sodium carbonate and quenched cullet. The preparation method comprises the following steps: uniformly mixing the raw materials, fusing at the high temperature of 1300-1400 DEG C, and carrying out water quenching treatment to obtain particles of which the sizes are 0.5-5mm. The invention has the advantages that (1) the slag temperature is lowered; (2) the raw materials permeate into the slag after being fused and the slag is solidified into large blocks which can be transported and stored conveniently; and (3) the residual heat is used for carrying out chemical reaction with the slag, thereby lowering the temperature for subsequently fusing the slag again when the slag is purified, shortening the reaction time and converting the heat energy.
Description
technical field [0001] The invention belongs to the field of slag treatment, in particular to a low-temperature solid slag frit and a preparation method thereof. Background technique [0002] The steel industry is the backbone industry of the country and plays a pivotal role in the national economy. However, the crazy mining of mineral resources and energy in the recent period has made resources increasingly scarce and scarce, which has become a worldwide problem. Therefore, how to make full use of mineral resources has become one of the effective ways to solve energy problems. [0003] The remaining slag after large-scale production also faces many problems: one is that the temperature is too high and needs to be transported away in time, and the other is that it is rich in iron and other rare earth components and needs to be recycled and refined. How to transport in time and solve the problems of dust flying and large land occupation during storage have always been the b...
