Pit Annealing Furnace
Pit Annealing furnace is the national standard energy-efficient operating cycle annealing furnace, mainly used in plate round stainless steel, steel, long shaft, rod type, fittings, metal parts and mechanical parts annealing heat treatment, also the ball can be, normalizing, quenching and heat treatment. Long rod-shaped workpieces, such as barrel, turbine shaft, rotors and other vertical load at pit furnace is heated, can avoid bending.
Pit Annealing furnace from the electric furnace, lining, lid, heating cabinets and other components. Furnace frame welded from steel and steel plate combination. Lining using high-alumina refractory bricks and refractory ceramic fiber cotton, made into a match with the furnace modules by tightening the stainless steel round bar is fixed on the furnace shell by tiling and methods laid up in. Hearth using perlite insulation tiles, fire-resistant clay composition standard insulation, load-bearing part of the heavy aluminum brick. When using a full fiber lining made insulation, the heating general high temperature resistance with heating, longer life, prone to breaking. Circular welded steel lid from the intermediate used in all refractory ceramic fiber rejection Sitan extrusion assembled combination, effectively guarantee insulation and sealing. Cover of movements using hand engine type, fully automated control have security, when the lid is opened automatically cut off the control power, to begin heating the lid closed to ensure the safety of operating personnel. Heating , processed into a spiral or wavy hanging on a cotton lining, and alumina ceramic nail to make positioning. Place densely welded stainless steel plate of furnace hearth.
