Introduction for this tools:
Constant cylinder warmth therapy character gasoline heat treatment furnace is widely utilized for warmth treatment of metal cylinder. The heating of the furnace is divided into two sections. A single part is the heating section (horizontal) the second segment is the large temperature section (horizontal).
Parameter and demands:
one.Ongoing heat treatment method furnace: complete duration for this machine is twenty meters(furnace is fifteen meters, loading & unloading holder is 5 meters). The furnace is welded by high top quality section steel, the furnace is lined with substantial temperature resistant substantial alumina refractory firebrick, insulation layer is produced of fiber and other thermal insulation supplies. General, the high temperature furnace is gentle and of good insulation efficiency.
two.Software: Cylinder normalizing heat therapy
3.Specification: ISO CZPT, cylinder weight:6kg/computer, 12.5kg/personal computer,twenty five and 52kgs Diameter of cylinder is from DN200-400mm
4.Working efficiency: 200pcs/hour
5.Entrance temperature: 30ºC
six.Cylinder heating temperature: 900ºC±25ºC
7.The max. working temperature of the furnace body: ≤1000ºC
8.The temperature rise of furnace body area is according to China industry expectations.
9.Elements of the furnace:
ten.Horizontal furnace human body: 1 set
11.Loading and unloading chain system: 1 pair
12.Nature gas control method(document made up of): one established
thirteen.Flue gas and heat exchange program: 1 set
fourteen.Gasoline kind: nature gas 
15.Gas calorific worth: 8500 Kcal / kg
sixteen.The form of combustion apparatus: substantial-velocity gas burner
17.Heating amount and thermal load distribution: 8 pcs gas burner
18.No. of burners in heating part:four pcs burners, 230KW/pcs
19. No. of burners in the entrance of temperature keeping section : two pcs burners, 230KW/pcs
twenty. No. of burners in the back conclude of temperature holding segment : 2pcs burners, 150KW/pcs
21.Energy supply: 20KW, 380V, 50Hz 
Burner and manage program:

1. Large pace gas burner and ratio control technique

Ongoing cylinder warmth treatment method furnace needs the equal warmth provide, equally loading the cylinder, and requirements to offer huge heating load changes, so we choose ratio burning control program. The sleeve tube on the burner nozzle will form a higher speed jet steam when burning, can stir up the within environment and similarly provide the warmth. The heating of each burner nozzle is ratio management.
In the ratio management method, the burner nozzle will automatically adjust the heating according to the temperature in the furnace, the electricity, mixture ratio, spraying pace will be adjusted to a greatest condition, which will efficiently enhance the burning potential and lessen the air pollution. By means of the cooperation of the numerous burner nozzles, the heat stream will be uniformly distributed in the furnace, which will improve the heating good quality of the cylinder and temperature uniform. We also decide on controller of substantial resolution and suited electricity burner nozzle to achieve a high linearity of the system. That variety of manage method is commonly utilised in metallurgy and device warmth remedy industry.

two. Operating station manage system

That technique has the feature of expansibility, adopts the handle method: 1 gauge- a single burner nozzle or a single gauge- multi-burner nozzles. The instrument adopts Japan conductive business SRS3 type clever temperature management instrument. Via hook up the signal of actual temperature in the furnace and then estimate by laptop to management the on/off and dimensions of the every burner nozzle, in the meantime , every single burner nozzle working situation can routinely go on in accordance to the pre-set curve. And it will show the temperature handle level and its temperature and the curve(also has paperless recorder), display the doing work problem of the burner nozzle, and failure warning.
The certain theory: the thermocouple will detect the temperature sign of really area furnace, then feed again to temperature instrument to check out the tolerance among the pre-established temperature and real temperature, then management the burner nozzle output by way of ratio management.

3. Alarm method and protection interlock system

Considering that the gas is character gasoline, which is harmful, so the safety technique is required. All the nozzles are equipped with automobile ignition gadget and flame detection unit, will output the warning sign when flame is out, the car ignition unit and flame detection gadget will minimize sown the solenoid valve, meanwhile there is indicator mild will tell which nozzle is down and begin and stop the interlock system. Audible and visible alarm will alarm to remind the operator to deal with the failure in time. There will is genuine-time keep an eye on and failure report in our electrical method.

four. CZPT tools: Japanese conductive meter, Chit or Delixi low strain electrical appliance, the cable wire is from inland well-known brand.

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

Primary content details:
one. The shell is welded by section steel and steel plate(large high quality metal)
two. Insulation fiber: ZheJiang
three. Large temperature refractory clay: HangCZPT
four. High temperature refractory brick: HangCZPT
