In the production process of blast furnace smelting, due to the low calorific value of blast furnace gas, it is difficult to achieve high hot air temperature in blast furnace hot-air stove with blast furnace gas as fuel. If you want the blast temperature of blast furnace to reach above 1200 ℃, it is necessary to preheat the blast furnace gas and combustion air, which is conducive to strengthening blast furnace smelting, reducing iron-making cost of production and saving energy. The metal gas and air preheater designed and manufactured by our company has the features of high working temperature and good reliability.

Product features:

(1) It can resist that dew point corrosion of high-acid media containing sulfur, chlorine and etc;

(2) Excellent temperature resistance, the highest working temperature can reach 1100 ℃;

(3) The graphite crystal has high hardness and strong wear resistance, which can withstand the long-term high-speed sweep of 50 mg/m³ dust and flue gas.
