Abstract

The invention relates to the technical field of intermediate frequency furnaces, and discloses a furnace building method capable of prolonging the service life of an intermediate frequency furnace, which comprises the following steps: S1, crushing and mixing raw materials, heating the raw materials to 80-90 DEG C, keeping the temperature at 80-90 DEG C for 10-15 minutes, and stirring and mixing in a stirrer; s2, a furnace lining blank mold with the corresponding size is manufactured according to the size of the furnace lining, the furnace lining blank mold is sintered, and then the furnace lining blank mold is cooled; s3, an induction coil and an alarm net are arranged in the furnace body, the induction coil and the alarm net are fixed, abrasive bricks are laid at the bottom of the furnace body, asbestos plates are laid on the upper layers of the refractory bricks, and then refractory materials are laid on the outer sides of the asbestos plates. And meanwhile, the safety coefficient in the operation process is obviously improved compared with the original furnace charge, the service life of the intermediate frequency furnace is prolonged, the number of built furnaces is reduced, and the furnace building workload of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of frequency furnaces, in particular to a furnace building method capable of improving the service life of an intermediate frequency furnace. Background technique [0002] The medium frequency induction furnace is widely used in the smelting of non-ferrous and ferrous metals. Compared with other casting and smelting equipment, it has the advantages of short smelting time, less burning loss of alloy elements, precise control of the temperature and composition of molten metal, and less environmental pollution. [0003] There is a common problem of short service life of the furnace lining during the use of the intermediate frequency induction furnace, especially when smelting different types of alloys or the melting temperature of the alloy is high, when the intermediate frequency furnace lining is made of ordinary quartz sand materials, the intermediate frequency furnace lining is severely scoured, and many Th...
