20-100 ℃/min heating and cooling rate muffle furnaceThe controller is working normally, but the ammeter is not displaying. The common fault is a broken circuit in the electric furnace wire. It can be checked with a multimeter and replaced with an electric furnace wire of the same specification. The double-layer furnace shell is equipped with an air-cooled circulation system, which can reach a temperature of 1200 ℃ and can work continuously at 1150 ℃ with a temperature control accuracy of ± 1 ℃. Check if the heating elements inside the high-temperature resistance furnace are broken. What is the reason why the high-temperature furnace does not heat up. (1) The power supply voltage is normal, and the furnace has good temperature field balance and insulation performance in electronics, glass, chemicals, machinery, refractory materials, new materials, special materials, building materials, etc.

20-100 ℃/min heating and cooling rate muffle furnaceThe heating and cooling are controlled by 30 programmable intelligent instruments, and the furnace tube is made of high-purity corundum tube, with a temperature of up to 1700 ℃. The screw lift furnace uses imported high-quality silicon molybdenum rods as heating elements, adopts a double-layer shell structure and intelligent temperature control system, and is controlled by controllable silicon.

There is a paper recorder, computer LCD touch screen, human-machine interface, communication connection function, multiple devices controlled by one computer, printing and saving data, achieving simple and convenient operation, and real-time viewing and saving of data. High quality silicon molybdenum rod crucible made of 99.99 fused silica is selected as the feeding mode. The upper feeding (feeding funnel can be equipped) voltage/AC/HZ380/50 rated heating power KW. Optional accessory paperless recorder heating time: 30-60 minutes Product use: can be designed and manufactured according to user needs with special specifications. Product details: AS-X-17 tube furnace is a single temperature zone tube furnace with phase-shifting trigger, and the furnace adopts imported 1800 type alumina polycrystalline fiber.Overvoltage, overcurrent, leakage, short circuit, etc. 100-200 ℃ 15-20 hours furnace door open 300-400 ℃ 8-10 hours furnace door open 550-600 ℃ 8h furnace door closed 750-800 ℃ 8h furnace door closed oven shell cover.
