Bell-type Furnace are made up of furnace covers, in two furnace places, two in covers, a cooling cover to be composed, heats up the cover to use the steel plate volume system to weld the formation densely, the furnace lining uses the energy conservation newest technology entire textile fiber modular structure, the furnace top folds the law high pressure for the entire textile fiber wave to tie up to hang the flat top, the high aluminum bolt loads clothing hung at full length the resistor tape, the furnace top installment diplopore quick freezing temperature decrease gate.

The furnace place for the heat preservation water cooling vacuum rubber seal structure, the stainless steel leads the wind seat stand, the high efficiency vacuum seal air blower.

In covers for the stainless steel plate volume system welds the formation densely, covers the bottom flange and the vacuum seal groove by large-scale sets up the vehicle lathe finishing processing formation.

Cooling covers by the double air blower screw blows of the rapid chilling. The vacuum pump is the 2X series turns on lathe the piece type mechanical vacuum pump.

Bell-type Furnace controls the warm cabinet to use the microcomputer procedure craft curve high accuracy to control automatically warm, completes the heat treatment craft curve automatically. By the microcomputer through the operation positive governing thyristor, carries on the adjustment to the furnace internal power, reduced the electrical network fluctuation, can act according to installs the furance quantity and the craft slope automatically from 0-100% change amount of power, realizes highly the festival electrically controlled warm.
