Rjfn square silicon steel sheet annealing furnace is a new type developed by our company on the basis of well type atmosphere protection annealing furnace. The furnace can load 3-10 tons of annealed workpieces at a time, has good temperature uniformity, three zone independent temperature control, and can automatically control and record the whole process of heating, holding, cooling and cooling according to the preset annealing process curve.

Square silicon steel sheet annealing furnace is used for the annealing of EI type or ladder type iron core; such as ring core, mutual inductance core, transformer core, motor core, amorphous magnetic material and other vacuum annealing treatment. After annealing, the iron core is bright without oxidation, eliminating the internal stress caused by mechanical processing, making the atoms in the metal have regular arrangement, improving the magnetic properties of silicon steel sheet coil core and reducing iron loss. The furnace has obvious advantages of structure application, simple and convenient operation, reliable process quality, high efficiency and energy saving. It is an ideal equipment for magnetic materials and transformer production industry.
