Well type carburizing furnace

Well type carburizing furnace charateristics: Full automatic temperature and action control, perfect alarming system

Well type carburizing furnace  Usage
The well type carburizing furnace is periodic operating furnace. It is mainly used for the carbon steel elementsgas carburizing and so on.
Feature
Its equipped with a vacuum-pumping system, which have no oxidation. And its carburizing speed is fast and carbon distributed is evenly.Although it has no fast cooling system, it could cool the workpiece fast according to the need, and its efficiency could be enhanced 1.5-2 times compares with the same pit gas carburizing furnace.Full automatic temperature and action control, perfect alarming system and locking protection device.
Structure
i, The furnace lining uses a ultra energy conservation structure. The hearth uses a special u-shaped brick, the surrounding insulation layer are all made from aluminum silicate textile fiber, simultaneously the furnace shells surface layer is covered a layer of asbestos board (when in low temperature the thermal conductivity is the smallest). This kind of structure has many advantages, such as good heat insulation effect, low energy storage, small heat losses, good thermal shock resistance, convenienced overhaul and so on, which improves the furnace lining life-span greatly.           ii, And the parameters of the electric furnaces power loss when its empty, the rised temperature of the fire walls and furnace temperature uniformity all surpass the national standards.     iii, The furnace covers rising and falling is accomplished by hydraulic lift mechanism.The heating temperature control unit table uses Japan (SHIMA) Corporations intelligence temperature control unit. This instrument configures self-tuning and standard PID arithmetic module, which could prevent temperature overshoot effectively. Meanwhile this measuring appliance also has function selection, configuration and parameters setting, and its setting value and practical value will be shown in digit. The major heating uses the SCR series combined type three-phase thyristor power controller and continuously non-make-and-break type. It is not the traditional electrical make-and-break type when controling, but it controls its heating power continuously and automatically according to the requirements of temperature control. The high efficiency temperature control has no noise and disturbance to internal electrical network, and its high to precision.
