Introduction for this gear:
Steady cylinder heat remedy nature gasoline warmth treatment furnace is commonly employed for warmth remedy of metal cylinder. The heating of the furnace is divided into two sections. One part is the heating segment (horizontal) the next part is the higher temperature part (horizontal).
Parameter and requirements:
1.Continuous heat treatment furnace: complete duration for this device is 20 meters(furnace is 15 meters, loading & unloading holder is five meters). The furnace is welded by high quality section steel, the furnace is lined with higher temperature resistant higher alumina refractory firebrick, insulation layer is produced of fiber and other thermal insulation components. Total, the high temperature furnace is light-weight and of very good insulation functionality.

Burner and control technique:

1. Large speed gasoline burner and ratio control method

Constant cylinder warmth treatment method furnace needs the equal heat provide, equally loading the cylinder, and wants to supply big heating load alterations, so we choose ratio burning manage program. The sleeve tube on the burner nozzle will kind a large velocity jet steam when burning, can stir up the inside environment and equally source the warmth. The heating of each and every burner nozzle is ratio manage.
In the ratio management program, the burner nozzle will routinely modify the heating in accordance to the temperature in the furnace, the electricity, combination ratio, spraying speed will be adjusted to a greatest problem, which will efficiently improve the burning capability and lessen the pollution. By means of the cooperation of the several burner nozzles, the warmth flow will be uniformly dispersed in the furnace, which will enhance the heating top quality of the cylinder and temperature uniform. We also choose controller of large resolution and appropriate electrical power burner nozzle to achieve a higher linearity of the system. That variety of manage method is broadly used in metallurgy and machine warmth therapy sector.

two. Doing work station management method

That technique has the attribute of expansibility, adopts the handle program: a single gauge- a single burner nozzle or one gauge- multi-burner nozzles. The instrument adopts Japan conductive company SRS3 kind smart temperature management instrument. Through join the signal of actual temperature in the furnace and then estimate by personal computer to control the on/off and measurement of the every single burner nozzle, meanwhile , each burner nozzle doing work issue can automatically go on in accordance to the pre-set curve. And it will present the temperature control point and its temperature and the curve(also has paperless recorder), demonstrate the functioning issue of the burner nozzle, and failure warning.
The distinct basic principle: the thermocouple will detect the temperature signal of very area furnace, then feed back to temperature instrument to verify the tolerance in between the pre-set temperature and real temperature, then control the burner nozzle output by way of ratio handle.

three. Alarm method and security interlock gadget

Since the gas is mother nature fuel, which is hazardous, so the safety system is needed. All the nozzles are outfitted with automobile ignition system and flame detection gadget, will output the warning signal when flame is out, the automobile ignition gadget and flame detection gadget will minimize sown the solenoid valve, in the meantime there is indicator light will inform which nozzle is down and begin and quit the interlock unit. Audible and visual alarm will alarm to remind the operator to offer with the failure in time. There will is genuine-time keep an eye on and failure file in our electrical program.

four. CZPT equipment: Japanese conductive meter, Chit or Delixi lower stress electrical equipment, the cable wire is from inland famous model.

5. Burner: ignition controller, push change, solenoid valve are from UAS Honeywell11 or German Krom, the hand valve and dish valve are from inland famous model.
