Structure Introduction:
The circle type resistance furnace comprises a furnace body, furnace lining, heating element device, furnace cover, sealing mechanism, electric control system, automatic temperature control system and recording system etc.

The furnace system: the furnace wall with steel and welded steel plate, steel plate thickness more than 3mm. Overall strong, solid, durable, reliable, all welds are smooth, no pores, slag inclusions, incomplete fusion and other defects. The furnace body appearance straight, beautiful, no wrinkles or uneven phenomenon. Outside the furnace body according to the related standard brush two times, two times paint primer. Color selection according to the industry standard, key parts with high temperature paint.

The lining: whole fiber lining structure, made of high quality aluminum refractory fiber structure, the standard and scientific and reasonable riveting firmware inserting method. Fiber folding block mounted again before the pre compression (compression density > 230Kg/m3), fixed on the shell by riveting firmware, insulation is installed thickness more than 240mm. The structure has a tensile strength of low heat conductivity and low heat soluble chemical stability, excellent thermal stability, heat shock resistance, excellent corrosion resistance and. Aluminum silicate fiber high temperature of 1050 DEG C, anchor material selection 304 sheet metal forming. The lining body after completion of production, spraying the surface with a layer of high temperature curing agent, forming a layer of insulation wall lining, increase strength and thermal radiation properties of a decent, and further reduce livestock lining body heat loss, achieve rapid heating effect, to maximize the thermal efficiency of the furnace.

Heating elements: in order to consider the uniformity of furnace temperature, the heating elements of the well type resistance furnace are arranged in the furnace around. The furnace is surrounded by high resistance alloy resistance belt which is produced by Shougang. The installation method of the electric resistance belt adopts special ceramic screw fixation, the structure form is convenient to install, the maintenance and replacement are fast, and the furnace shell can not form a thermal short circuit and cause the local overheating of the furnace shell. The ceramic gasket is arranged between the fiber wall and the resistance belt at the time of installation to ensure that the fiber surface is not in direct contact with the resistance strip, thereby increasing the heating effect of the resistance band. Ceramic screws and washers are made of high aluminum material in the sintering process, to ensure that the strength and service life.

The furnace cover: the furnace cover for 3mm carbon steel, lining for the fiber structure, and the sealing of the furnace body is sealed by sand.

Control and record system: temperature control with 1 control zone, using intelligent digital temperature controller in Shanghai dragon company (TCW-32B), by setting the reasonable parameters, can achieve optimal temperature control, self-tuning function using the online, can calculate the best PID parameters of the stove, reached the ideal temperature stability the. The heating control high power circuit adopts the bidirectional controllable silicon to adjust work, so as to change the size of the output heating power, so as to realize the temperature control. In the heating control circuit, the temperature is over temperature alarm system. When the temperature is over, the main circuit is cut off by the high power contactor in the main circuit to ensure the safety of the workpiece and the equipment in the furnace. At the same time give sound and light alarm. Recording instrument using well-known manufacturers to produce reliable performance paperless recorder. The electric furnace is controlled by 1 zones, the temperature of the master and the temperature of the recording. All of the silicon controlled rectifier, AC contactor, fuse, relay, circuit breaker, switch, switch, button operation, signal lights and other main controller and display device with reliable operation, well-known domestic and foreign manufacturers to produce products.
