Laboratory furnace

Laboratory heating furnace uses:
Laboratory furnace is mainly used in the use of the institutions of higher learning, research institutes, industrial and mining enterprises and other experiments and small batch production. Mainly used in electronic ceramic products calcined, sintering, coating, pyrolysis of low-temperature deposition (CVD) process.
Laboratory furnace features:
Laboratory furnace with high temperature ceramic or refractory bricks, Outside SECC steel, fine powder coating process.
The seal is made of aluminum plates.
Circular way: thermal radiation (three or four sides heated).
Heating method: PID + SSR or PID + SCR;
Heating material for high-temperature heating wire or silicon carbide;
Temperature range; room +20-1200; (Note: The temperature is adjustable)
Temperature controller: PID microcomputer control;
Timer: timer, thermostat function, temperature and time, the time to cut off the heating power;
Safety Protection: over-temperature protection, high temperature protection, over-current protection.
Can pass an inert gas (such as nitrogen);
Laboratory heating furnace structure:
Laboratory heating furnace temperature distribution in the furnace along the longitudinal direction is divided into a preheating section, heating section and a soaking zone; feed end of the lower furnace for preheating section, and its role is to use the heat of the furnace gas, in order to improve the thermal efficiency of the furnace . Heating as the main heating segment, the gas temperature is higher, in order to facilitate the rapid heating. Soaking zone is located in the discharge end, the gas temperature and metal material temperature difference is small, to ensure uniform temperature of the charge blank section. Stove for heating small cut fabric blank only warm-up and the heating section. Customary to also install the burner in the furnace for tropical divided furnace segment, in accordance for the number of tropical stove called the one-, two-stage, to five sections, Six-. 50 to 60 years, the mill capacity to increase the length of the pusher-type furnace is limited by the length of the Pusher not be too long, so start at the feed end of the increase for tropical canceled heating preheating section, in order to improve The productivity of the unit hearth area. This stove heated slab, bottom yield per unit area of ??900 to 1000 kg / (m 2 ·), the heat consumption of approximately (0.5 to 0.65) × 106 kcal / ton. Since the 1970s, due to energy needs, but also emerging stepping furnace allows to increase the length of the furnace, and additional heating preheating section, the best hearth yield per unit area of ??600 to 650 kg / (m 2 · Time), the heat consumption of approximately (0.3 to 0.5) × 106 kcal / ton.
