The test furnace heating speed is fast, the temperature is uniform; Can be used for carbon steel, alloy steel, tool steel, die steel and aluminum alloy, such as quenching, annealing, tempering, cyanide, aging and other heat treatment; It can also be used for steel precision forging with less oxidation heating. When using the test furnace for heat treatment, we must pay attention to the following details to ensure the operation safety of the test furnace and make the test go on normally. Here are some more important experimental electric furnace operation knowledge:

The test furnace heating speed is fast, the temperature is uniform; Can be used for carbon steel, alloy steel, tool steel, die steel and aluminum alloy, such as quenching, annealing, tempering, cyanide, aging and other heat treatment; It can also be used for steel precision forging with less oxidation heating. When using the test furnace for heat treatment, we must pay attention to the following details to ensure the operation safety of the test furnace and make the test go on normally. Here are some more important experimental electric furnace operation knowledge:
1. When the workpiece is quenched under vacuum, vacuum quenching oil should be used, which has a lower saturated vapor pressure.
2, test furnace treatment of titanium alloy, should not use nitrogen as the cooling gas, because titanium and nitrogen reaction at high temperature, the formation of golden titanium nitride.
3. The maintenance of the test furnace should be in the state of vacuum or pure nitrogen, to prevent suction and moisture absorption when usually not in use.
4. Vacuum heating is mainly radiation, and the workpiece should be kept at a distance in the furnace.
5. The heating temperature of vacuum tempering, vacuum annealing, vacuum solution treatment and vacuum aging is generally the same as that of conventional treatment.
6. In the process of heating up, the workpiece and the materials in the furnace will be deflated, so that the vacuum degree will decrease.
7, cold furnace use, because the furnace is cold, must be a lot of heat absorption, so the low temperature section heating rate should not be too fast, various temperature section heating rate difference should not be too large, setting the heating rate fully consider the physical and chemical properties of sintered materials, to avoid the phenomenon of spray, pollution of the furnace.
8, regularly check whether the contact of the electrical connection part of the temperature control system is good, and special attention should be paid to whether the connection of the heating element is strong. If not, it must be reinforced immediately.
