Production process of slag cone in refractory materials

In order to better balance the composition and particles of various dry materials and cement clinker, it is necessary to carry out mixing and add fusion agents to improve the compressive strength of the billet fusion. Such as aluminum silicate fiber felt billet added fusion clay, magnesium billet added sulfite paper pulp wastewater, silica billet added aluminum chloride and so on. According to the amount of water content of the billet, semi-dry desulfurization molding (about 5% water), plasticity molding (about 15% water) and grouting molding (about 40% water) can be selected. Then drying and firing are carried out. The melting method is to melt the raw materials through the process of mixing and fine grinding, melt at high temperature, cast immediately, and become products by cooling crystallization and quenching. Such as melting zirconium corundum bricks, corundum bricks and magnesia bricks. Their billets have high density, high impact toughness, high compressive strength at high temperature, good slag resistance, and the application scope continues to expand. The fusion injection method is to melt the ingredients, and then develop the gas producer with high pressure gas or saturated steam, and disperse it into chemical fibers or hollow balls. The key products as light fire, insulation materials. In addition, it can also be made into powder or granular amorphous refractory materials, and when used, it can be immediately applied with the fusion agent powder sand such as nicotine, leached, concrete, polyphosphate, potassium thiocyanate or isopropyl titanate, without forming and calcination.

According to the high density level of the product and the appearance design is not the same, there are calcination method, melting method and melting injection method. Calcination method is a part of the raw materials pre-burned to perfect the material, crushed and screened, and then mixed with dry material according to a certain preparation, after forming, drying and firing. The purpose of raw material pre-burning is to burn away the water, organic chemical residue and dissolved vapor of potassium thiocyanate in it to reduce the firing of the product and ensure the accuracy of the product size. The raw material must also be screened after grinding and milling, because the billet is carried out by the mix ratio of particles with different particle size distribution, it can ensure that the high-density billet is deposited inseparably.
