High temperature and high strength repair material is a special material used to repair equipment and structures in high temperature environments.
High-temperature and high-strength repair material is composed of high-strength aggregate, binder, wear-resistant additives and appropriate amount of admixture powder. It is a high-aluminum-content hydraulic unshaped refractory material made through mixing, stirring, molding, curing and other processes.
(1) High strength, wear resistance, and strong pressure resistance;
(2) Good corrosion resistance;
(3) Good thermal stability and excellent high temperature resistance;
(4) Fast hardening and drying speed, saving time;
(5) Good durability and long service life;
(6) Easy to use, cast and easy to construct.
(1) Widely used for cold and local emergency repair of ladles. The workability of the product can be adjusted according to different usage methods. It can also be used for small-capacity, thin-walled, and complex-shaped ladle linings.
(2) Emergency repair and routine maintenance repair of the furnace body, furnace throat, iron tapping ditch, slag tapping ditch, and slag skimmer of iron-making blast furnaces.
(3) Emergency repair and routine maintenance repair of the furnace bottom, bridge, forehearth, iron tapping port, and slag tapping port of cupolas.
(4) Emergency repair and routine maintenance repair of the furnace mouth, furnace nozzle, and working layer of induction furnaces.
(5) Emergency repair and routine maintenance repair of the ladle edge, ladle nozzle, ladle wall, and spheroidizing reaction tank of cast iron and cast steel running ladles.
