1.改进前的加热淬火工艺改进前,推土机铲刀片加热淬火工艺采用箱式电阻加热炉加热。箱式电阻加热炉利用电阻元件把电能转变成热能,将铲刀片在炉内加热并保温。保温完成后将铲刀片出炉,用淬火机床冷却铲刀片,完成淬火工艺。以D60型推土机铲刀片为例,每件铲刀片质量约38.6kg。按照工艺规范要求,箱式电阻加热炉只
1. Before the improvement of the heating and quenching process before the improvement, the bulldozer shovel blade heating and quenching process using a box-type resistance heating furnace. Box resistance furnace using resistive elements to convert electrical energy into heat, the blade in the furnace heating and insulation. After the insulation is completed, the blade is released, and the blade is cooled by a quenching machine to complete the quenching process. Take the D60 bulldozer blade as an example, each blade has a blade mass of about 38.6kg. In accordance with the requirements of process specifications, box resistance furnace only
