第二重型机器厂热处理车间工人和技术人员学习日本先进技术,最近试制成功了无铁芯工频感应加热器。过去,我国采用的工频感应加热器是带铁芯的单、双线圈感应加热器,但有着淬硬度和深度达不到要求,可靠性差,结构复杂,以及用硅钢片制作铁芯造价昂贵等缺点。无铁芯感应加热器试制成功,不仅克服了上述缺点,而且填补了我国淬火工艺设备上的一个空白,为今后过渡到整体感应加热打好基础。
The second heavy machinery factory heat treatment workshop workers and technicians to learn advanced technology in Japan, the successful trial of the recent iron core frequency induction heater. In the past, the frequency induction heater used in our country was a single and double coil induction heater with iron core, but it had the requirements of quenching hardness and depth, poor reliability and complicated structure, and the iron core made of silicon steel sheet was expensive Other shortcomings. Iron core induction heater trial success, not only to overcome the above shortcomings, but also to fill a blank on the quenching process equipment in China for the future transition to the overall induction heating lay the foundation.
