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.

Pressure protection
The system is specially made to prevent the danger of closure of the exhaust port , the
blockage of the exhaust port and the excessive pressure of the furnace tube.
The signal is obtained by the electric contact pressure meter or pressure sensor then the drive control module will closes the electromagnetic inlet valve and starts
the electromagnetic exhaust valve and the alarm. to ensure the furnace can be use properly and safely.
Gas leak alarm
Base on gas atmosphere, to prevent the gas leak;Gas leakage alarm detected (indoor) air toxic, dangerous and other gas content
exceeds a certain value,then the drive control module will shut-down the furnace,closes the inlet valve and open the air exhaust,to get the better and safety working environment.
