Lower row's burner heating control apparatus is set to lower part in burner hearth；
Wherein, lower row's burner heating control apparatus includes: lower row's burner, lower part thermocouple, bottom temp PID control
Device and safe PID controller, lower row's burner is successively horizontally arranged, and the lower part thermocouple is set to lower row's burner every two
Centre, the bottom temp PID controller and safe PID controller are connect with furnace body following side.
Further, upper row's burner heating control apparatus include: upper row's burner, upper temp PID computing controller and
Upper thermocouple, upper row's burner is successively horizontally arranged, is corresponding in turn to and connect on the upside of the upper thermocouple and upper row's burner,
The upper temp PID computing controller is connect with furnace body upper lateral part.
The utility model has the beneficial effects that
Compared with traditional technology, new construction can be not allowed the utility model to avoid because of side burner thermometric, cause under burner
Portion's burning or few burning make the upper and lower surface uneven heating of heated product in heating furnace.Add bottom temp PID controller and peace
The new control program of full PID controller to arrange the linkage variation of burner heating amount up and down, ensure that blank upper and lower surface is heated equal
Even property.
Detailed description of the invention:
Fig. 1 is the structure chart of the utility model.
Appended drawing reference:

Specific embodiment
Below in conjunction with specific embodiment, progress explanation is made to the utility model.It should be understood that following embodiment is merely to illustrate
The utility model is not for restriction the scope of the utility model.
Embodiment 1
Fig. 1 is the structure chart of the utility model.
As shown in Figure 1, a kind of walking beam furnace for hot rolling includes: furnace body 100, burner hearth 200, the heating of upper row's burner
Control device 300 and lower row's burner heating control apparatus 400, burner hearth 200 are set in furnace body 100, upper row's burner computer heating control dress
It sets 300 and is set to 200 inner top of burner hearth, lower row's burner heating control apparatus 400 is set to lower part in burner hearth 200；
Wherein, lower row's burner heating control apparatus 400 includes: lower row's burner 410, lower part thermocouple 420, bottom temp
PID controller 430 and safe PID controller 440, lower row's burner 410 is successively horizontally arranged, and lower part thermocouple 420 is set to lower row
The centre of 410 every two of burner, bottom temp PID controller 430 and safe PID controller 440 and 100 following side of furnace body connect
It connects.
Upper row's burner heating control apparatus 300 include: upper row's burner 310, upper temp PID computing controller 320 and on
Portion's thermocouple 330, upper row's burner 310 is successively horizontally arranged, the company of being corresponding in turn on the upside of upper thermocouple 330 and upper row's burner 310
