KTL1600 Atmosphere Tube Furnace
Product Description: The KTL1600 atmosphere tube furnace uses 1800 type silicon molybdenum as the heating element, adopts a double-layer shell structu
Product details

KTL1600 AtmosphereTube furnaceUsing a silicon molybdenum rod as the heating element, a double-layer shell structure and a Japanese island electric temperature control instrument, it can perform 40 stage program temperature control, phase shift triggering, and thyristor control. The furnace is made of alumina polycrystalline fiber material, and the two ends of the furnace tube can be sealed with stainless steel flanges. The stainless steel flange is equipped with gas nozzles, valves, and pressure gauges. When vacuuming, the vacuum degree can reach 10-3 Pa. This furnace has the advantages of temperature field balance, low surface temperature, fast temperature rise and fall rate, and energy saving. It is an ideal product for universities, research institutes, and industrial and mining enterprises to conduct high-temperature atmosphere sintering, atmosphere reduction, CVD experiments, and vacuum annealing.


model Power kw Furnace tube size mm Dimensions mm supply voltage Number of phases
KTL1600-60 5 φ60*1000 1120*490*855 220V single-phase
KTL1600-80 5 φ80*1000 1120*490*855 220V single-phase

(1) The hot end thickness D1 of silicon molybdenum rod is 7mm, which is commonly used by manufacturers as 6MM. 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) It adopts hot bending technology, with uniform resistance and long service life

(3) Lu's cold end length is 210mm, and the 400X300X300 furnace has a length of 260. Generally, manufacturers use 180mm, and the long cold end has a low furnace top temperature.

(4) The surface of the silicon molybdenum rod has a dense amorphous oxide film, which can effectively protect the silicon molybdenum rod.



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


The KTL1600 atmosphere tube furnace can be equipped with communication interfaces and software, which can directly control various parameters of the furnace through a computer, and observe the PV and SV temperature values and instrument operation on the furnace 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 time 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.




(All imported electrical appliances certified by UL)


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

(2) Current limiting function: No matter how we adjust the heating time, the secondary current of our electric furnace after passing through the transformer is limited to 170A, which provides limited protection

Protected the equipment. Non current limiting trigger, if the heating rate is set incorrectly or too fast, and the current is very high at low temperatures, the equipment will 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.


(1) The transformer cable is made of pure copper

(2) The sound of the transformer is low

(3) Transformer body temperature is low
