液压加煤空气射流锻造加热炉(图1)实际上是空气射流无烟锻造加热炉的炉体配用上海消防器材厂的“液压自动推煤阶梯炉排”。这两部分都经过了多年的生产验证,效果很好。该新炉型的突出优点在于炉型主体结构更适合于热交换过程的进行。它是从苏式煤炉演变而来的。从改善热交换性能着手,设计了曲线型炉顶,缩小了炉膛空间,改进了排烟系统,以强化炉气再循环,提高炉膛的保温性能。过去由于空炉待锻等原因,全年综合煤铁比为0.8左右。自“空气射流无烟锻造加热炉”定 Hydraulic coal air jet forging furnace (Figure 1) is actually a jet of air forging smokeless furnace equipped with Shanghai Fire Equipment Factory, “automatic hydraulic coal-fired ladder grate.” Both parts have gone through many years of production verification and worked well. The outstanding advantage of the new furnace is that the furnace main structure is more suitable for the heat exchange process. It evolved from the Soviet-style coal stove. Starting from the improvement of heat exchange performance, a curvilinear roof is designed, the furnace space is reduced, the smoke exhaust system is improved, the furnace gas recirculation is strengthened, and the thermal insulation performance of the furnace is improved. Past due to empty furnace forging and other reasons, the annual comprehensive coal-iron ratio of about 0.8. Since “air jet smokeless forging furnace” set
