The KBF1400 atmosphere box furnace uses silicon carbon rods as heating elements, adopts a double-layer shell structure and a Japanese Island Electric 40 segment program temperature control system, with phase-shift triggering and thyristor control. The furnace uses alumina polycrystalline fiber material, and the double-layer furnace shell is equipped with an air cooling system, which can quickly raise and lower the temperature. The shell is sealed as a whole, the cover plate is sealed with silicone mud, and the furnace door is sealed with silicone pad and connected to a water cooling system. The gas enters the back chamber through a flow meter and can be evacuated by a vacuum pump. There are combustion nozzles at the furnace inlet and outlet, which can pass hydrogen, argon, nitrogen, oxygen, carbon monoxide, ammonia decomposition gas and other gases. The furnace has a balanced temperature field, low surface temperature, and fast temperature rise and fall rate. Energy saving and other advantages are beneficial for universities, research institutes, and industrial and mining enterprises to protect the atmosphere during sintering Ideal product for atmosphere restoration.

(1) The hot end thickness D1 of silicon carbon rod is 14mm, which is 12mm commonly used by manufacturers. The heating end is thick, not easy to bend, and the surface load of the rod is low, resulting in a long service life.

(2) The length of the cold end is 210mm, and generally manufacturers use 180mm. The cold end is long and the furnace top temperature is low.

(3) The amorphous oxide film on the surface of the silicon carbide rod is dense, which can effectively protect the silicon carbide rod.

When the circuit experiences overcurrent or leakage, the circuit will automatically disconnect

This atmosphere tube furnaceapproveEquipped with communication interfaces and software, the various parameters of the furnace can be directly controlled through a computer, and the PV and SV temperature values and instrument operation on the furnace can be observed from the computer. The actual heating curve of the furnace will be drawn in real time by the computer, and the temperature data at each moment can be saved and retrieved at any time

(1) High quality high-purity alumina polycrystalline fiber solidification furnace formed by vacuum suction filtration.
(2) Adopting Japanese technology for molding.
(3) The furnace material has low heat capacity and low thermal conductivity, resulting in less heat dissipation, good insulation, and high reflectivity. Temperature field equilibrium.
(4) The furnace alumina wire is thin and long, with high temperature resistance and strong resistance to thermal expansion and contraction
(5) The furnace surface is smooth and not prone to powder loss.

1Phase shift trigger (with soft start and current limiting function)

2. Current limiting function: No matter how the heating rate is set, the secondary current of our electric furnace is always limited to within 170A, effectively protecting the equipment. Due to the use of current limiting function, the furnace door can be opened at high temperatures. If the electric furnace you are using needs to limit the heating rate of the furnace during the heating process (for example, it is specified that the heating rate should not exceed 1400 ℃)

If the temperature exceeds 3 ℃/min, non current limiting triggers are used. The heating rate is set incorrectly or the heating rate is too fast, and the current will be affected in this caseVery large, the equipment may trip or burn out.

3. Soft start function: When starting up, the current will gradually increase, which has less impact on the heating element and is beneficial for extending the life of the heating element

4. Protection function: If the current exceeds the limit current, the trigger will automatically cut off the triggering function to cut off the current protection of the electric furnace.
