Electric heating system:
1. Temperature measurement system
The company is involved in aluminum liquid using imported integrated graphite temperature measuring bar, furnace design straight ceramic temperature measuring bar, in order to accurately measure the furnace, aluminum liquid current temperature.
2. Heating system
The furnace is installed with 6 heaters, bilateral wiring, to ensure the temperature of aluminum soup; The heating of the heater will be automatically adjusted by SCE and the SCR will be controlled by the output ratio of the thermostat. The operation sequence and principle are as follows:
2-1 close the air switch (power switch), open the control circuit switch, the control circuit is energized, the furnace, aluminum liquid temperature controller shows the current temperature, and then set the required temperature;
2-2 turn on the heater switch, and the heater starts to work. If the current temperature of the furnace and aluminum liquid is set by the light rain, the heating indicator will be on, the contactor will suck in, and the heater will start to heat up;
2-3 when the heater works and the temperature rises, and the current temperature of furnace and aluminum liquid exceeds the set temperature, the over-temperature indicator light will be on and the heater will automatically stop working.
2-4 In the heating process, the larger the difference between the setting temperature and the current temperature, the larger the output current, the smaller the difference, and the smaller the output current.
2-5 furnace, aluminum liquid temperature controller shows that the current temperature is lower than the set temperature, the heater will work, if one of them is higher than the set temperature, the heater will not work.
Product features:
1. Energy saving and cost reduction.
2. During heat preservation and die-casting production, the energy consumption is about 33.7% lower than that of ordinary electric furnace.
3, the refractory lining for high heat insulation lining with high density, long service life and low maintenance cost, without electricity for 8 hours, furnace temperature about 100 ºC (closed).
4, Japan energy saving resistance wire (sg-52), improve the quality of aluminum alloy solution, improve the quality of die casting, reduce waste loss.
5. Two-compartment structure, effectively preventing oxides from entering the soup taking chamber (built-in partition).
6, high adiabatic high density lining with "non-stick aluminum" function.
7, simple maintenance, continuous use of a month slag maintenance can be.
8. The furnace wall is made of 6mm thick steel plate with integral folding, and the interior is made of fire-resistant insulation technology (fiber cotton, firebrick) with high thermal insulation performance to eliminate discomfort caused by thermal radiation to operators.
9, when the normal use, the average temperature of furnace wall is less than 42 ºC won't produce waste gas and noise, eliminate employees were holding furnace wall burns.
10, the world's most advanced SCR proportional control energy saving system, SCR proportional control output, simple operation, zero fault.
11, the bottom of the furnace adopts the alarm indicator of aluminum leakage from the safety door, with a higher safety factor.
