Our company produces large, medium, and small ironmaking blast furnaces with anhydrous gun mud at the tap hole, using brown corundum, silicon carbide, bauxite clinker, coke, pyrophyllite, and silicon nitride iron as the main raw materials, and using tar, resin, and other binders for mixed rolling and extrusion.
Main features:
Our company can adjust the production process according to the relevant technical parameters of the blast furnace to meet the usage requirements of different blast furnaces and operating environments. The products have the following characteristics:
1. During the use of the anhydrous gun mud, the iron ditch is easy to deliver mud and basically does not emit mud; The iron mouth is easy to open, there is no iron leakage, and there are few damp iron grooves. The iron grooves are easy to dry, which can greatly promote the production of the blast furnace and reduce the labor intensity of the workers in front of the furnace
2. During the use of the anhydrous gun mud, the operation performance is good, it is easy to extrude from the mud gun machine, the filling density is high, the fast sintering performance is good, and a certain sintering strength can be achieved in a short time, fully adapting to the requirements of short or even no interval iron tapping;
During the use of this anhydrous gun mud, the iron production condition is stable, with strong resistance to iron and slag erosion. The iron production and slag production conditions are good, especially suitable for the simultaneous discharge of large blast furnace iron and slag.

notes | The plasticity index (MPa) needs to be determined based on the specific mud pressure of the mud gun machine. This technical parameter is only an example and is not a guarantee value for the company's products. We will study the smelting products, operating methods, and furnace conditions of the blast furnace based on the usage data, and adjust them to achieve the best usage effect |
