由于塑料工业迅猛发展,塑料制品在工业与人民生活中越来越占重要地位。因此,其工作母机——挤塑机需求量也日益增长。螺杆与机筒是挤塑机的主要部件。由于是在一定温度下工作,因此要求它们具有一定的综合机械性能,表面具有高的耐磨性与耐蚀性能。为此我厂选用了南京摄山电炉厂的RN-110-6K三米井式气体氮化炉,于85年6月安装调试完毕,6月投产使用。 Due to the rapid development of plastic industry, plastic products occupy an increasingly important position in industry and people’s life. As a result, the demand for its main machine, the extruder, is also growing. Screw and barrel are the main components of the extruder. Because it is working at a certain temperature, so they require a certain degree of overall mechanical properties, the surface has high wear resistance and corrosion resistance. To this end, I chose the plant Nanjing Nanjing Electric Furnace RN-110-6K three-well gas nitriding furnace, in June 85 installation and commissioning completed in June put into use.
