一、课题提出 热双金属是我所的主要产品之一。它是由两种热膨胀系数不同的金属通过特殊加工工艺结合而成的精密合金产品。热双金属在航空和轻工等工业中用来制作控制设备和测量仪器的热敏感元件,如家用电器电冰箱、洗衣机、电饭锅等中作为控制元件。 历年来,我所传统采用的双金属热轧工艺流程如下: First, the subject proposed thermal bimetal is one of my main products. It is composed of two different thermal expansion coefficient of the metal through a special combination of precision machining alloy products. Thermal bimetal is used as a control element in the thermal and aeronautic components used in the aerospace and light industry industries to make control equipment and measuring instruments such as household appliances refrigerators, washing machines, rice cookers and the like. Over the years, I used the traditional hot-rolled bimetal process is as follows:
