car entire fiber furnace

HARDUN series car entire fiber furnace are mainly used for hardening, annealing and ageing of high chromium or high manganese steel castings, die steels, rolls, steel balls, breaking hammers and wear-resisting line-plates, they also can be used for heat treatment for large mechanical parts.

1.The lining of HARDUN series car entire fiber furnace is entire fiber structure, compared with refractory brick hearth , it can save energy by 30-60%, the high quality fiber is standard specifications produced by special equipment, what is more, during manufacturing of this fiber, there should be certain draught , which can ensure ceramic fiber expand at all directions and form a no-gap refractory structure, and finally ensure good heat insulating characteristic. The fiber can be directly fixed on the steel plate of the furnace shell with stainless nail. Compared with other products, it has low heat conductivity, low heat capacity, corrosion-resistance, good thermal stability and heat insulation.

2.Heating elements are made of high temperature electric-resistant alloy which is belt-shaped or spiral-shaped, and they are respectively fixed on bricks on sides, door, back and pallet of the furnace with high aluminum ceramic nails, which ensure safety and neatness.

3.There is pressure and high temperature resistant cast steel bottom plate on the pallet, in case of dropping of oxide scale around heating elements, the bottom plate and furnace body are connected in inserted mode, usually, you should better clean pallet bottom plate with compressed air once a week, which can prevent short circuit caused by oxide scale of workpieces.

4.The furnace door system is comprised by door, lifting structure and hold down mechanism. The door is welded with section steel and plates, inside is refractory fiber, which should be heat-insulating and light.
