SQ2-7-14 Controlled Atmosphere Furnace 

Introduction:

This chamber furnace with silicon carbide as the heating element, use of double-shell structure and 30-stage program system, phase-triggered trigger, SCR control, furnace using alumina polycrystalline fiber materials, Air-cooled system, It can quickly rise and lower temperature, the use of the overall shell seal, cover the use of silica gel mud, the door with a silicone gasket and a water-cooled system, gas flow through the breech after the out, a number of washing furnace intake Gas, nitrogen, oxygen, carbon monoxide, ammonia decomposition gas and other gases, the furnace has a temperature field equilibrium, surface temperature is low, temperature rise and fall rate is fast,energy-saving,And other advantages isthe ideal reduction products for university, research institutes, industrial and mining enterprises to do atmosphere protection sintering.

Component Configuration:

First, temperature control instrument : With Xiamen Yu-program temperature control instruments

1,30 stages intelligent temperature PID control program.

2,With over-temperature protection, break-even protection, over-temperature or broken when the furnace heating circuit will automatically cut off (when the furnace temperature exceeds 1420 degrees or thermocouple blown, the main circuit of the AC relay will disconnect the main Circuit disconnected automatically , the panel lights off the Swtich, OFF lights, limited protection electric furnace).

3, With 485 communication interface (Optional software when the standard).

4, With a power-off protection, that is after the power to start the stove, the program is not started from the initial temperature rise, but start the power when the furnace began to rise.

5, the instrument has function of temperature self-tuning.

Second, open door protection system: The furnace is equipped with a trip switch, when the lid is opened cut off the powerautomatically , effectively guarantee the safety of users.

Third,Furnace material: the United States imported furnace material, not powder, good insulation properties, high reflectivity, temperature field balance, resistance to heat and cold shrink ability.

Fourth, heating element: all used with Dia14mm silicon carbide rods, rod surface load have low, long service life.

5, Leakage protection (optional): the furnace installed leakage of air switch, when the furnace leakage or current exceeds the rated current time and space will automatically shut down to cut off the power.

6,Software control system: The furnace is equipped with communication interface and software, you can directly through the computer control of the various parameters of the stove, and from the computer to observe the stove on the PV and SV temperature and instrument operation, furnace actual heating curve.

The computer will draw in real time, and can save the temperature data of each moment, at any time can be transferred out.

7, Control system: 1,electrical appliances: Chint. 2,SCR: Germany Simon Kang 106 / 16E. 3,the trigger: phase shift trigger.

8, Gas supply system (optional): the gas supply system can be on the float flowmeter or proton flow meter to control flow of gas.

9,Vacuum system (optional): the atmosphere can be pre-chamber vacuum furnace to speed up the cleaning of the furnace air.

10,Sealing system: the furnace roof and door (other places have been welded) are used silicone O-ring extrusion seal,easy to remove, removable removal, air tightness, and can ensure that the pointer gauge 8 hours without deflection.

11, Explosion-proof system (optional): Explosion-proof system contains asolenoid valve, microcomputer, pressure display and transmitter, 24V power supply, AC contactor and other components. Pressure in the furnace through the pressure transmitter and the display is converted to electrical signals transmitted to the microcomputer, microcomputer and set comparison the value and then give the signal to control the AC contactor, thus controlling the solenoid valve off. When the furnace pressure is greater than the allowable

pressure set by us, the solenoid valve immediately open, play a role in explosion-proof, solenoid valve installed on the trachea, the user can connect the pipe to the air to the outdoors.

The explosion-proof system has many advantages:

1, With reusability: Pressure is greater than the set value when the solenoid valve is opened, the pressure is lower than the set value when the solenoid valve is closed, unlike the mechanical anti-riot device, a burst can not be used.

2,Setting value is adjustable: the user can adjust the electromagnetic valve through the microcomputer to open the pressure

3,Explosion-proof point is very sensitive: because use of micro-computer and electrical signals, the pressure immediately to detonation point to detonate.

4,Explosion-proof system security: detonated when there is no debris flying out. (If the use of mechanical may have glass flies)

5,Explosion-proof system stability: As a result of micro-computer and solenoid valve, to our set point must detonate, the user can test, unlike the mechanical can not test, explosion-proof point will open due to there are a lot of uncertainty.
