FKT series annealing (normalizing) furnace adopts composite heating method. Gas and electricity, fuel and electricity, etc are applied to produce heat in the furnace, it is a furnace superior to the bell furnace, pushrod furnace, etc. This furnace (production line) adopts rapid annealing new technology and innovated technology, has the advantages such as compact structure, precise temperature control, simple and convenient operation, reliable running, low energy consumption, meeting to the requirements of environment protection, annealing quality surpassing the standard JB/T1255-2001, etc. It realized the goal of high efficiency, high quality, low energy consumption, continuous production in spheroidal anneal, so this furnace is a green heat treatment equipment. This kind of furnace is suitable for the continuous annealing (normalizing) of bearing ring, hardwares, steel pipes, bars, coiled bar, strip steel, alloy tool steel, etc., is widely used for the preheating treatment of the precision forging, cold rolling, cold expansion parts.
