新设计是根据引进的日本川崎公司的贸易许可证。可以使加热炉节油。方法是,将废气先不送入烟囱,而是引入一个预热室。这种预热设备又可以作为炉中的对流带,可建造在炉子前方或近旁。热废气在室中通过许多耐热喷嘴,由上、下方对加热的钢材进行喷吹,这样废气和材料内的传热通过高速热气流 The new design is based on the introduction of the Japanese Kawasaki company’s trade license. You can make the furnace fuel-efficient. Instead of sending the flue gas to the chimney first, a preheating chamber is introduced. This preheating device, in turn, can act as a convection zone in the furnace and can be built in front of or near the furnace. The hot exhaust gases pass through the chamber through a number of heat-resistant nozzles and the heated steel is sprayed from above and below so that the heat transfer within the exhaust gas and the material passes through the high velocity hot gas stream
