Problems solved by technology

[0012] At present, there are still some problems to be solved in the production of continuous magmatic rock fibers, such as poor thermal permeability of pure natural magmatic rock melt, high crystallization upper limit temperature and easy crystallization, and short material properties. Therefore, the production process of magmatic rock fiber has certain advantages. Difficulty in fiber formation, strict process control conditions and high requirements for equipment adaptability are technical difficulties. Strict screening must be carried out for natural magmatic rock minerals and components, and it is difficult to design the chemical composition and main mineral components of prepared magmatic rock fiber materials. Conducive to the realization of large-scale and stable industrial production
[0013] In the prior art, there is no literature report on the use of industrial solid waste gasification slag as a raw material for the preparation of magmatic rock fibers
