我公司锻造车间的2.25m~2简易煤气推杆式连续加热炉的二次风管夹角,根据有关资料介绍设计成水平向下30°～45°夹角(见图1)。炉子建成后,发现炉膛内的温度不均匀,对着射角部位的坯料温度很高,有时前后几件料被烧得粘在一起脱不开,而有的料被推到炉门口时还达不到始锻温度,影响模锻生产,并且炉门口还有大量的火焰冒出。造成了热量损失。后来,我们把 The secondary air duct angle of 2.25m ~ 2 simple gas push rod type continuous heating furnace of our company’s forging workshop is designed to be horizontal downward 30 ° ~ 45 ° according to relevant data (see Figure 1). After the furnace is built, it is found that the temperature inside the furnace is not uniform, and the temperature of the billet at the angle of incidence is very high. In some cases, a few pieces of material are burned to stick together, while others are pushed to the door of the furnace Less than the initial forging temperature, affecting the forging production, and the furnace door there is a large number of flame emerge. Caused a loss of heat. Later, we put
