Introduction for this tools:
Steady cylinder heat therapy nature gasoline warmth treatment furnace is broadly utilised for heat remedy of steel cylinder. The heating of the furnace is divided into two sections. 1 area is the heating area (horizontal) the next area is the substantial temperature segment (horizontal).
Parameter and needs:
1.Steady warmth remedy furnace: complete length for this machine is twenty meters(furnace is 15 meters, loading & unloading holder is five meters). The furnace is welded by high good quality section steel, the furnace is lined with high temperature resistant higher alumina refractory firebrick, insulation layer is created of fiber and other thermal insulation materials. Overall, the high temperature furnace is mild and of good insulation performance.
two.Application: Cylinder normalizing heat remedy

five.Entrance temperature: 30ºC
six.Cylinder heating temperature: 900ºC±25ºC
7.The max. doing work temperature of the furnace human body: ≤1000ºC
eight.The temperature increase of furnace human body floor is according to China sector standards.
nine.Parts of the furnace:
ten.Horizontal furnace physique: one set
11.Loading and unloading chain system: one pair
twelve.Nature gas control method(document made up of): 1 established
thirteen.Flue gas and heat trade system: 1 set
fourteen.Gasoline kind: mother nature gas
15.Gas calorific worth: 8500 Kcal / kg
sixteen.The form of combustion equipment: large-speed gas burner
seventeen.Heating quantity and thermal load distribution: 8 pcs gas burner
eighteen.No. of burners in heating section:4 pcs burners, 230KW/pcs
19. No. of burners in the entrance of temperature keeping part : two pcs burners, 230KW/pcs
twenty. No. of burners in the again finish of temperature keeping segment : 2pcs burners, 150KW/pcs
21.Electrical power offer: 20KW, 380V, 50Hz
Burner and handle program:
one. Substantial speed gas burner and ratio handle system
Continuous cylinder heat remedy furnace requires the equal warmth provide, equally loading the cylinder, and wants to give massive heating load alterations, so we choose ratio burning control method. The sleeve tube on the burner nozzle will form a higher pace jet steam when burning, can stir up the inside environment and similarly supply the heat. The heating of every single burner nozzle is ratio handle.
In the ratio manage program, the burner nozzle will instantly alter the heating according to the temperature in the furnace, the electrical power, combination ratio, spraying velocity will be modified to a best condition, which will successfully increase the burning potential and minimize the air pollution. Via the cooperation of the a number of burner nozzles, the heat circulation will be uniformly dispersed in the furnace, which will increase the heating high quality of the cylinder and temperature uniform. We also choose controller of substantial resolution and suited electrical power burner nozzle to get to a substantial linearity of the system. That kind of management technique is commonly used in metallurgy and equipment warmth remedy industry.
two. Working station control system
That program has the characteristic of expansibility, adopts the management system: 1 gauge- one particular burner nozzle or a single gauge- multi-burner nozzles. The instrument adopts Japan conductive company SRS3 variety intelligent temperature management instrument. Through hook up the sign of true temperature in the furnace and then calculate by pc to handle the on/off and dimensions of the each burner nozzle, meanwhile , every burner nozzle doing work condition can automatically go on in accordance to the pre-set curve. And it will present the temperature management level and its temperature and the curve(also has paperless recorder), display the functioning situation of the burner nozzle, and failure warning.
The certain principle: the thermocouple will detect the temperature sign of quite section furnace, then feed again to temperature instrument to check out the tolerance among the pre-established temperature and true temperature, then control the burner nozzle output via ratio control.
three. Alarm technique and safety interlock system
Since the fuel is character gas, which is hazardous, so the protection system is needed. All the nozzles are equipped with auto ignition system and flame detection device, will output the warning sign when flame is out, the vehicle ignition unit and flame detection system will cut sown the solenoid valve, meanwhile there is indicator mild will inform which nozzle is down and start and stop the interlock device. Audible and visual alarm will alarm to remind the operator to offer with the failure in time. There will is actual-time keep an eye on and failure file in our electrical method.
four. CZPT equipment: Japanese conductive meter, Chit or Delixi minimal stress electrical appliance, the cable wire is from inland popular brand name.
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 brand.
