muffle furnace price
Vacuum muffle furnace is widely used in metallurgy, glass, chemical industry, machinery, special materials, gemstones, magnetic materials, building materials, (plastics, food, feed, tea, rubber ash test) (hardening of metal molds, annealing, tempering, heat treatment) and other fields.
Vacuum Muffle Furnace
1, control accuracy: + 0.3 centigrade%.
2. Adopting 30-segment PID can only adjust the temperature of digital temperature controller, double-row digital display, brand-new digital display and intelligent control technology can reduce the error of trial reading and manual operation, greatly improve work efficiency, key setting, overtemperature alarm, PID self-tuning function, arbitrarily adjustable power consumption, overtemperature power cut off and stop heating. Programmed heating and cooling can be set up, and the control box is equipped with a working indicator to show the working conditions and faults of the electric furnace.
3. The furnace is made of clean high-temperature refractory with good heat preservation performance, thermal shock resistance, high temperature resistance, rapid cooling and heat resistance.
4. The temperature categories are 1000 C and 1200 C.
Muffle furnace price:
Muffle furnace, as a commonly used laboratory heating equipment, has various specifications and models. The price difference of muffle furnace is quite different. How to judge whether the price of muffle furnace is reasonable?
Muffle furnace price is greatly influenced by refractory materials, and the price of silicon carbide furnace and firebrick furnace is almost the same. Taking the most commonly used 300*200*120 stove, the price between 2000 and 4000 yuan is reasonable. Muffle furnace price is too low, quality and after-sale can not be guaranteed, too high, if the price exceeds the value.
Now most laboratories will choose ceramic fiber furnaces, which are much more expensive than silicon carbide and refractory brick furnaces. Similarly, the muffle furnace in the 300*200*120mm furnace is generally priced at more than 7000 yuan.
Why is there such a big difference? This is because the ceramic fiber furnace is about ten times the price of the refractory brick furnace, and it is not surprising that the price is so much higher.
Vacuum muffle furnace points for attention
Vacuum atmosphere muffle furnace, tubular furnace in use because of the different vacuum requirements in the end, can be matched with different vacuum pumps.
General single-stage rotary vane vacuum pump with load up to 130pa, bipolar rotary vane vacuum pump with load up to 5 pa, if the vacuum degree is higher, it is necessary to choose a vacuum unit. The vacuum unit can reach below 1pA.
Generally, the places where gas is leaked easily is weld, solder joint, or sealing strip. If the threaded pipe is connected, the place where the raw material belt is wrapped is easy to leak, so the raw material belt should be entangled.
In case of high vacuum, high vacuum flapper valve should be equipped, otherwise the pressure rise rate will be very large.
