When the furnace is rolled or forged steel thermal equipment for heating billets or small ingot. Heating furnace body from the furnace wall, bottom and lid and other components. It is not used in high temperature castable alumina balloons Inner Mongolia, generally at 1400 ℃ about. For continuous heating furnace or ring, etc., the various parts of the furnace temperature is substantially constant, can be divided into low, medium temperature, high temperature with three segments, namely become preheating zone, plus both tropical and tropical, the temperature respectively of 800 ~ 900 ℃, 1150 ~ 1200 ℃, 1200 ~ 1300 degrees Celsius. Lining damage is mainly because the temperature of intermittent operation and shutdown furnace caused fluctuations caused by deformation and thermal lining peeling. Damage to the wall and the furnace bottom portion is mainly molten slag and iron oxide chemical reaction caused by brick. So Liaoning alumina bubble castable, according to the different conditions in different parts of the choice of different refractories. Aluminum-magnesium refractory castable is developed on the basis of sodium silicate refractory castable aluminum-magnesium on the medium and small ladle, which has achieved good results. When to use more high-grade refractory materials, formulations scientifically designed materials can be formulated in a successful high-tech aluminum-magnesium refractory castable, available in a large, use the ladle to improve the package age. Slag resistance of aluminum-magnesium refractories, and magnesium aluminate spinel refractory castable similar, but better than aluminum spinel refractory castable, so it is the choice of domestic and foreign users Heilongjiang castable alumina hollow ball, especially in Japan widespread use on the ladle. In addition, the material in the large-scale blast furnace iron ditch ditch Desilication pour use, its life expectancy than Al2O3 - SiC - C iron trough material. Tianjin Gute energy saving Technology Co., Ltd. is a heat resistant lining materials technology research, material production and brickwork lining construction as one of the professional engineering company, the China Petrochemical heat resistant lining Engineering Corporation and China Petrochemical Group, the fourth lining engineering construction company founded on the basis of restructuring the company, after years of development, the company has formed a brickwork lining construction petrochemicals, coal chemicals, energy conservation and environmental protection-related devices, heat resistant lining material development and technical services for the core business development pattern of the business. It has passed the GB / T19001-2008 quality system certification, GB / T28001-2001 occupational health and safety system certification and GB / T24001-2004 environmental management system certification, the national kiln engineering contracting business.
