Introduction to Gunning Mix
Gunning mix is a refractory material that is used in various industrial applications, especially in high - temperature environments. It is typically applied by gunning or spraying onto the surface of furnaces, kilns, and other thermal equipment. The main function of gunning mix is to provide a protective lining that can withstand extreme heat, chemical corrosion, and mechanical abrasion. This helps to extend the service life of the equipment, improve energy efficiency, and ensure the quality of the production process. Gunning mix can be made from different raw materials such as alumina, magnesia, silica, and zirconia, depending on the specific requirements of the application.
