加热炉是锻造工艺的主要设备之一，一座理想的加热炉，应该具有热效率高、使用寿命长、操作方便、消除污染等优点。近几年，我厂对原加热炉进行了合理改进，实践证明基本上达到了上述目标。改进后的加热炉其特点如下：1．将加热炉的预热室空间加大，由此提高了热能的利用率，并 Heating furnace is one of the main equipment forging process, an ideal heating furnace should have the advantages of high thermal efficiency, long service life, easy operation, pollution elimination. In recent years, our factory has carried on the reasonable improvement to the original heating furnace, the practice proved that has basically achieved the above goal. The improved furnace features the following: 1. The heating furnace room preheating room increases, thereby increasing the utilization of thermal energy, and
