Introduction for this products:
Steady cylinder heat therapy mother nature gas heat treatment furnace is commonly used for heat treatment of steel cylinder. The heating of the furnace is divided into two sections. 1 section is the heating area (horizontal) the 2nd area is the higher temperature part (horizontal).
 
Parameter and requirements:
one.Constant heat treatment method furnace: complete duration for this device 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 higher temperature resistant higher alumina refractory firebrick, insulation layer is manufactured of fiber and other thermal insulation components. Total, the high temperature furnace is gentle and of very good insulation overall performance.

Burner and management program:

1. Large velocity gasoline burner and ratio management program

Continuous cylinder heat remedy furnace demands the equal heat supply, equally loading the cylinder, and wants to supply large heating load modifications, so we select ratio burning control method. The sleeve tube on the burner nozzle will form a substantial speed jet steam when burning, can stir up the inside ambiance and equally supply the heat. The heating of every single burner nozzle is ratio handle.
In the ratio handle technique, the burner nozzle will automatically change the heating according to the temperature in the furnace, the electricity, combination ratio, spraying pace will be altered to a greatest problem, which will efficiently enhance the burning potential and minimize the pollution. By way of the cooperation of the numerous burner nozzles, the heat circulation will be uniformly dispersed in the furnace, which will enhance the heating good quality of the cylinder and temperature uniform. We also decide on controller of higher resolution and ideal energy burner nozzle to attain a substantial linearity of the technique. That type of control system is extensively utilized in metallurgy and device warmth therapy industry.

2. Functioning station management program

That technique has the feature of expansibility, adopts the manage method: one particular gauge- one burner nozzle or a single gauge- multi-burner nozzles. The instrument adopts Japan conductive company SRS3 sort clever temperature control instrument. Via join the signal of true temperature in the furnace and then determine by computer to handle the on/off and measurement of the every single burner nozzle, meanwhile , each and every burner nozzle operating condition can automatically go on in accordance to the pre-established curve. And it will show the temperature manage point and its temperature and the curve(also has paperless recorder), demonstrate the doing work situation of the burner nozzle, and failure warning.
The distinct basic principle: the thermocouple will detect the temperature signal of extremely area furnace, then feed again to temperature instrument to check the tolerance among the pre-established temperature and genuine temperature, then control the burner nozzle output via ratio management.

three. Alarm system and safety interlock unit

Considering that the gasoline is character gas, which is unsafe, so the protection technique is necessary. All the nozzles are outfitted with auto ignition gadget and flame detection unit, will output the warning signal when flame is out, the auto ignition device and flame detection gadget will reduce sown the solenoid valve, in the meantime there is indicator mild will tell which nozzle is down and begin and quit the interlock device. Audible and visual alarm will alarm to remind the operator to offer with the failure in time. There will is real-time keep track of and failure file in our electric technique.

four. CZPT tools: Japanese conductive meter, Chit or Delixi minimal pressure electrical equipment, the cable wire is from inland well-known manufacturer.

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