1200Single temperature zone tube furnaceIt is a device developed for the sintering, melting, and analysis of metal, non-metal, and other compounds in controlled atmospheres and vacuum states for laboratories and industrial and mining enterprises in higher education institutions and research institutes.
The services provided by our company1200 degree single temperature zone tube furnaceThe structure:
It mainly consists of furnace body, control system, heating elements, and other parts. The furnace body usually adopts a double-layer structure, with the inner layer made of stainless steel and the outer layer made of carbon steel to enhance its heat resistance and insulation. Heating elements often use resistance wires or silicon carbide rods to provide a uniform and stable heating source. The control system may include different temperature control strategies based on different models, such as PID control, programmed heating and cooling, etc. In addition, there are usually certain safety measures in place, such as over temperature protection, couple breaking protection, etc., to ensure safe use.
Attention should be paid when using:
1. Control the heating rate: When using a cold furnace, as the furnace is cold and requires a large amount of heat absorption, the heating rate in the low-temperature section should not be too fast. The difference in heating rate between different temperature sections should not be too large. When setting the heating rate, the physical and chemical properties of the sintered material should be fully considered to avoid material spraying, pollution of furnace tubes, and affecting the use of furnace tubes.
2. Monitoring operation status: The entire heating process should be supervised by a dedicated person, and attention should be paid to automatic control instruments during operation to prevent instrument malfunctions from causing excessive temperature.
3. Pay attention to pressure changes: When the temperature of the furnace body is above 1000 ℃, the furnace tube cannot be in a vacuum state. The pressure inside the furnace tube should be equivalent to atmospheric pressure and maintained at atmospheric pressure; When using a cold furnace, if it is necessary to close the gas valve to heat the sample, it is necessary to always pay attention to the reading on the pressure gauge. If the absolute pressure gauge reading is greater than 0.15 MPa, the exhaust valve must be opened immediately to prevent accidents.
