The production line of mesh belt hot air circulation tempering furnace is composed of feeding table, heating furnace, tempering furnace body, discharging table, mesh belt transmission system, hot air circulation fan, temperature control over temperature alarm, etc.

Tempering furnace: the furnace bottom is made of lightweight energy-saving insulation bricks, the furnace top both sides of the furnace are made of aluminum silicate refractory fiber blanket with high temperature resistance, which has excellent heat insulation performance. The all fiber furnace lining is very light in weight has excellent heat preservation performance. Compared with the brick resistance furnace of the same specification, the energy saving rate is about 30%, the heating rate is increased. The theoretical design heating rate is about 2 hours.

Tempering furnace shell: the shell of heating section is formed by 314 steel plate, the upper furnace cover can be removed for operators to repair clean the furnace. It is possible to strengthen the strength of the bottom of the tank reduce the friction coefficient between the mesh belt the furnace bottom. Reinforcing ribs are set at the top edge of the tank to increase the service life prevent the collapse of the bladder under high temperature.

Furnace lining: the furnace body of our company adopts all fiber structure. The fiber is made into modules according to the furnace size. The fiber is compressed into blocks for field cotton building. The lining is lined with high temperature resistant alloy wire wound into resistance wire. The ceramic tube straight rod series connection type is respectively installed on the upper side of the heating zone, the straight rod type heating element can be on the side of the furnace hearth for easy maintenance replacement.

Hot air circulation system: two powerful centrifugal fans are installed on the top of tempering furnace body. The centrifugal fans can effectively circulate the hot air flow under the action of the flow guiding system in the furnace. The fan is composed of a blower a guide plate. The blower motor is electrically interlocked with the heating element. Only when the blower is connected can the heating element be powered on, so that the heating element can work under the condition of ventilation circulation.

Temperature control system: the mesh belt tempering furnace is equipped with a new type of furnace temperature automatic control instrument system, which adopts Japan Shimbun Power Co., Ltd. the temperature controller can set the heating rate, holding temperature, holding accuracy cooling speed respectively according to the set process curve, so as to realize the automatic adjustment control of temperature rise slope, holding temperature, holding time cooling, display the theoretical value measured value, so as to improve the control level control Temperature accuracy. The temperature control system also has the function of over temperature sound light alarm.
