Introduction for this gear:
Steady cylinder warmth remedy mother nature gasoline warmth treatment furnace is broadly utilized for warmth treatment method of steel cylinder. The heating of the furnace is divided into two sections. One part is the heating segment (horizontal) the second part is the high temperature area (horizontal).
Parameter and specifications:
one.Ongoing heat treatment method furnace: total length for this equipment is twenty meters(furnace is 15 meters, loading & unloading holder is 5 meters). The furnace is welded by high high quality section steel, the furnace is lined with large temperature resistant high alumina refractory firebrick, insulation layer is produced of fiber and other thermal insulation resources. Total, the high temperature furnace is light and of excellent insulation efficiency.
2.Software: Cylinder normalizing warmth therapy
three.Specification: ISO CZPT, cylinder fat:6kg/personal computer, 12.5kg/personal computer,25 and 52kgs Diameter of cylinder is from DN200-400mm
4.Functioning effectiveness: 200pcs/hour
five.Entrance temperature: 30ºC
6.Cylinder heating temperature: 900ºC±25ºC
7.The max. doing work temperature of the furnace human body: ≤1000ºC
8.The temperature increase of furnace human body surface is in accordance to China market standards.
nine.Components of the furnace:
ten.Horizontal furnace physique: 1 established
eleven.Loading and unloading chain system: one pair
twelve.Mother nature gas control program(record containing): one set
13.Flue gasoline and heat exchange system: one set
fourteen.Gasoline sort: nature gas 
15.Gas calorific price: 8500 Kcal / kg
16.The kind of combustion equipment: higher-pace gasoline burner
seventeen.Heating amount and thermal load distribution: 8 pcs gas burner
18.No. of burners in heating area:four pcs burners, 230KW/pcs
19. No. of burners in the entrance of temperature keeping area : two pcs burners, 230KW/pcs
twenty. No. of burners in the again finish of temperature holding segment : 2pcs burners, 150KW/pcs
21.Electrical power source: 20KW, 380V, 50Hz 
Burner and control method:

1. Large velocity gas burner and ratio management method

Ongoing cylinder heat treatment furnace needs the equivalent heat supply, equally loading the cylinder, and requirements to provide large heating load modifications, so we select ratio burning management program. The sleeve tube on the burner nozzle will form a high velocity jet steam when burning, can stir up the within environment and similarly supply the warmth. The heating of every single burner nozzle is ratio manage.
In the ratio control technique, the burner nozzle will immediately alter the heating according to the temperature in the furnace, the electricity, mixture ratio, spraying velocity will be adjusted to a very best issue, which will properly enhance the burning capability and decrease the air pollution. Through the cooperation of the many burner nozzles, the warmth movement will be uniformly dispersed in the furnace, which will increase the heating quality of the cylinder and temperature uniform. We also select controller of higher resolution and appropriate electrical power burner nozzle to get to a high linearity of the technique. That sort of manage program is widely utilised in metallurgy and equipment warmth therapy business.

2. Doing work station control system

That technique has the characteristic of expansibility, adopts the management system: a single gauge- 1 burner nozzle or 1 gauge- multi-burner nozzles. The instrument adopts Japan conductive business SRS3 variety smart temperature management instrument. By means of link the signal of actual temperature in the furnace and then determine by computer to control the on/off and size of the every burner nozzle, meanwhile , each burner nozzle operating situation can automatically go on in accordance to the pre-set curve. And it will show the temperature manage level and its temperature and the curve(also has paperless recorder), demonstrate the functioning problem of the burner nozzle, and failure warning.
The specific basic principle: the thermocouple will detect the temperature signal of extremely segment furnace, then feed again to temperature instrument to check the tolerance in between the pre-set temperature and genuine temperature, then handle the burner nozzle output through ratio handle.

three. Alarm method and safety interlock unit

Since the gas is nature fuel, which is dangerous, so the security system is necessary. All the nozzles are outfitted with automobile ignition device and flame detection unit, will output the warning sign when flame is out, the vehicle ignition device and flame detection system will cut sown the solenoid valve, in the meantime there is indicator gentle will inform which nozzle is down and commence and quit the interlock system. Audible and visible alarm will alarm to remind the operator to deal with the failure in time. There will is actual-time check and failure record in our electric method.

four. CZPT equipment: Japanese conductive meter, Chit or Delixi reduced force electrical appliance, the cable wire is from inland popular manufacturer.

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

Main substance specifics:
one. The shell is welded by section steel and steel plate(large high quality metal)
two. Insulation fiber: ZheJiang
