我厂生产的1吨翻斗车半轴,坯料拔杆后需经局部加热再在空气锤上镦出头部。过去用油炉加热,一年生产6000余根半轴,耗柴油20多吨。后来,我厂将油炉改造成半煤气炉(见图)。几年来,已取得了明显的经济效果。 I produced 1 ton dump truck half-shaft, blank after pulling the rod by local heating and then upset in the air hammer head. In the past with oil furnace heating, more than 6,000 a year axle production, consumption of more than 20 tons of diesel. Later, I converted the oil furnace into a semi-gas furnace (see photo). In recent years, obvious economic results have been achieved.
