Brief introduction of vacuum atmosphere tube furnace

    The vacuum atmosphere tube furnace can heat treat the sample in the high-pressure oxygen environment or inert gas environment. The high temperature can reach 1100 ℃, and the pressure gauge and high-pressure relief valve are installed on the furnace tube flange. Therefore, when the pressure in the tube is higher than the set value, the relief valve will automatically open to exhaust, so that the pressure in the tube reaches the set value. Therefore, especially for the exploration and research of superconducting materials and dielectric materials, this high-temperature blast furnace is a good and inexpensive experimental tool.

    The heating element of the vacuum atmosphere tube furnace adopts high-temperature molybdenum containing resistance wire, and the furnace insulation material adopts polycrystalline fiber material, which has good insulation performance, durability, high tensile strength, no impurity balls, high purity, and energy saving effect is obviously superior to domestic fiber materials. The whole furnace body adopts a double-layer inner tank structure, with an air gap in the middle. Even if the furnace temperature reaches the high temperature of Zui, the furnace body surface can still be safely touched without a feeling of scalding.

    The temperature, furnace size, vacuum degree, temperature control accuracy, power and temperature rise and fall rate of the purchased vacuum furnace shall be determined according to their own experimental requirements. In addition, heating elements are also very important. Heating elements include alloy wire, silicon carbon rod, silicon molybdenum rod, Mo sheet, graphite, etc.
