The equipment designed for sintering, melting, analysis and production ceramics, metallurgy, electronics, machinery, chemical, glass, refractories, for develop new material ,special materials,construction materials,the equipment is suitable  for institutions of higher learning and laboratory of scientific research institute and industrial and mining enterprises.

Characteristic:
1、Maximum using temperature:1300 ℃；Heat Material: U Type silicon carbied rod(Model:20-400-250-50) ；Temperature accuracy：±1℃;  Thermocouple Number: S;  The furnace has 8 channel digital display paperless grapher; The furnace has track and movable. The length of heat zone is 7500mm, Furnace Temperature Uniformity Zone 6500mm, Furnace Temperature Uniformity ±8 ℃，Working capy 180KW; Voltage 380V。

2、Furnace structure using high temperature spray plastic to resistance acid and alkali and also having corrosion-proof, Delicate double color collocation make the appearance more generous, delicate and beautiful. Furnace shell welded up by national standard angle iron and cold rolled plate.Double layer shell, inside and outside isolation, Air cooling structure, surface temperature less then 40℃。Furnace stack welded up by national standard angle iron and cold rolled plate and using lathe to do delicate reprocessing to ensure the best seal effect. the movable wheel has installed under each furnace stack, wheel run at track to ensure furnace can do rectilinear movement. Track length 15M (Five Segment ) it can disassemble. Furnace stack connected with screw conntion and auxiliary buckle lock; At the first segment and last segment of furnace we has install the directional bearing . for easy control and better installation, the furnace stack is considered to be lengthened in the future, and it is designed for the remolding of the future furnace.

3、Equipment control part：easy micro-computer opertion,programmable,PID self-tuning, auto temperature rise, auto heat preservation,auto cooling,

No artificial . Every euqiment coennected with paperless recorder. Every recorder can record the temperature rise and cooling data and temperature rise rate at every moment. Maximum 4 hour can reach 1300 ℃；Temperature rate 1℃/h-15℃/min can be motify; Furnace using seven set control furnace ,one set Main control instrument and 6 set sub-control  instruments, seven set control furnace can communication with each other.to ensure the furnace temperature rise rate can be at same curve. The electrical circuit using integrated circuit, module control; double loop protection (partial temperature protection, high temperature protection, thermocouple protection, over current protection, over voltage protection) to ensure the furnace working can more stable and reliable . electric cabinet have two set spare parts control space.

4、Furnace cooling control : furnace internal designed has speedy cooling device. the device can make sure when the furnace full load, the temperature can reduce from 1200℃to 70℃within 12 hour . and the control can programmable ,it also has paperless recorder to record the cooling curve.

5、heat element arrangement；first segment and last segment , heating zone length 1.7m, each segment has 24 pieces U type silicon carbied rod; Another firve segment at middle part each segment 800mm long ,each segment using 12 pieces U type silicon carbied rod; Total :108 pieces using at heating zone.

6. refractory material and furnace harth structure, he furnace hearth using double layer for isolation heat,furnace harth using import alumina fiber as heat perservation, the energy saving effect more then 60% compare with the traditional furnace; furnace bottom and support using Heavy refractory material, excellent wear resistance, high temperature resistance and weight bearing effect,guarantee the electric furnace above the 2500kg. furnace entrance using light weight refractory brick;furnace wall and furnace top using alumina fiber material; structure reasonable and stable. Heat resistant, Resistance to thermal heat and clod, without cracks, without crystallization, without dregs and without pollution; use high density and high temperature knitted blanket, supplementary sealing;

7、cooling(air cooling) device structure：outside furnace hearth using axial flow fan around air cooling; 4 air channel inside furnace hearth; the exhaust port exhaust cone type sealing device is provided In the electric furnace and a valve at the inlet for convenient the user to connect the pipe and exhaust the high temperature gas and waste gas outside. Exhaust port is higher then furnace 1200mm;air channel material, elicit pipe made by 316L texture material. External valve use 304 texture material. furnace internal hearth all using 310s stainless steel pipes and stainless panel; there is a high pressure blower at air cooling supply space,air filter are stetted at inlet and outlet of air fan; air speed:5-609 m³/h can be modify; noise less then 90db.

8、paperless recorder technology means program control curve maximum can be 100 segments paperless grapher it has 1 to 8 channels. Grapher input are full switching universal input,input thermocouple, thermal resistance, standard current signal and so on,can also provide the feedback current signal .and also using modern USB interface technology, can directly saving data at pen drive,longer record time. Paperless grapher have the powerful display function,Real time trend curve display, large character digital display, historical curve recollection, overrun alarm, alarm state display、It provides intelligent historical trend full automatic playback function. It is very convenient to locate alarm points. It also provides location and playback function, directly querying data of a year, month, day, hour, minute and second, and is convenient and quick.
