一、概述 工频感应加热和熔炼,近几年来已普遍应用于生产。但采用工频感应加热真空炼松香为数极少,至今绝大多数松香生产厂仍然采用以木柴为燃料的直接火法生产,工艺落后,设备陈旧,松香质量难以提高,还要烧掉大量木柴,针对上述原因,我厂于1982年开始对工频感应加热真空炼香成套设备进行设计制造,1983年在光泽县林化厂安装使用,实践证明技术先进,经济合理,节约木材,保护森林资 First, an overview of frequency induction heating and melting, in recent years has been widely used in production. However, the use of frequency induction heating vacuum refining rosin is extremely rare, so far the vast majority of rosin production plants still use firewood as a fuel direct fire production, backward technology, outdated equipment, rosin quality is difficult to improve, but also burn a lot of firewood, In view of the above reasons, our factory started to design and manufacture complete sets of equipment for induction heating vacuum vacuum incense in 1982. In 1983, it was installed and used in Guanghua County Forest Plant, and proved to be technologically advanced, economical and reasonable, saving timber and protecting forest resources
