The tubular furnace is a new type of electric furnace with high performance and energy saving developed by ourselves with international advanced technology, including single-tube, double-tube, horizontal, open-type, vertical, single-temperature zone, double-temperature zone and three-temperature zone. Mainly used in colleges and universities, scientific research institutes, industrial and mining enterprises and other experimental and small batch production. Safe and reliable, simple operation, high temperature control accuracy, good heat preservation effect, large temperature range, high uniformity of furnace temperature, temperature area, optional atmosphere, vacuum furnace type, etc.
Characteristics of a tubular furnace
1, the appearance of high temperature, corrosion resistant paint treatment.
2. The console adopts intelligent PID digital display controller with good stability and high precision, equipped with ammeter and novel structure.
3. The furnace door is thickened and strengthened to prevent deformation.
4, furnace lining using high purity alumina and insulation cotton, insulation effect is good.
5, the furnace temperature constantly detection function (under the condition of no heating also display the actual temperature of the furnace, easy to observe the temperature of the furnace). 6. The furnace shell is made of steel plate flanged and welded. The workroom is a furnace made of refractory materials.
Atmosphere protection and furnace mouth cooling device
1) Be sure to connect the water cooling loop (lower in upper out) to cool the furnace mouth before using the tubular furnace. Water shortage is strictly prohibited. Cut-off valve is provided for inlet water, and the outlet water outlet shall not be installed.
2) Before using the tubular furnace (and during heating at the same time), the protective atmosphere loop must be ensured to be normal. The atmosphere is nitrogen or argon. The gas is routed through the vacuum globe valve, flow meter and vacuum pump. The gas is fed into the furnace tube in two ways, one of which is nitrogen and the other is hydrogen. And equipped with a vacuum interface, in the other end of the furnace tube exhaust. The discharge is adjusted through the gate valve. Before the furnace heating, start the vacuum pump first and pay attention to the vacuum pressure gauge. When the value of vacuum pressure is close to -0.1mpa, turn off the power supply of the vacuum pump. Open the pipe stop valve and adjust the air source pressure at 0.1mpa. Adjust the inlet flow rate and exhaust valve according to the process requirements to maintain the pressure inside the furnace up to 500Pa.
3) Note: The mouth of the electric furnace is sealed with silicon rubber strip. In case of failure after a period of use, it should be replaced immediately.
