Description
Technical field
The present invention relates to a kind of heat treatment pressure monitoring device and its application methods, belong to heat-treatment furnace production technology neck
Domain.
Background technique
Furnace pressure monitoring is the important link in open fire heat-treatment furnace thermal control process.Furnace pressure monitors improper not only shadow
The safety for ringing heat-treatment furnace, also will cause industrial furnace waste of fuel.
Currently, the monitoring for heat-treatment furnace pressure, mainly simply installs pressure monitor, then according to instrument
Display carries out the supply or discharge of gas manually, it is thus desirable to special personnel supervise on side always when production, one
Denier supervisor carelessness, gently then causes furnace pressure unstable, heavy then may cause production accident.In addition, open fire heat treatment now
The infeed end of the gas of furnace operates intermittently, and discharge end is continuously discharged.Since the discharge end of gas maintains a normally open, and
Furnace pressure is in micro-positive pressure, therefore the protective gas in furnace is constantly in discharge state, is bound to cause the waste of protective gas；
Simultaneously as the continuous discharge of gas, by there are protective gas in the unnecessary loss and furnace cavity that bring heat
Flow field, pressure in the burner hearth distribution is uneven always, may cause certain positions and forms negative pressure, heat loss increases, and then influences furnace
Interior temperature uniformity causes the waste of fuel.
Summary of the invention
To solve the problems in the background art, the present invention provides a kind of heat treatment pressure monitoring device and its use
Method.
Realize that above-mentioned purpose, the present invention take following technical proposals: a kind of heat treatment pressure monitoring device, including at heat
Manage furnace, pressure sensor, control system, gas handling system and outlet system, the inlet end and gas handling system of the heat-treatment furnace
Connection setting, the outlet side of heat-treatment furnace and outlet system connectivity are arranged, and are provided with pressure sensor, the control on heat-treatment furnace
System processed and pressure sensor, gas handling system and the equal signal transmission of outlet system connect.
A kind of heat treatment pressure monitoring device of the invention and its application method, described method includes following steps:
Step 1: the air pressure in pressure sensor monitoring heat-treatment furnace, and by data Real-time Feedback to control system；
Step 2: control system issues order according to the data that pressure sensor is fed back；
If the air pressure in heat-treatment furnace is relatively low, control system controls air inlet valve group to gas；
If the air pressure in heat-treatment furnace is higher, control system controls the exhaust of outlet valve group.
Compared with prior art, the beneficial effects of the present invention are: the present invention feds back through control according to pressure sensor
System controls gas handling system and outlet system, intelligent operation, that is, saves human resources, and increase the safety of operation；
Meanwhile gas handling system and outlet system are controlled by control system, avoid feed end operate intermittently and discharge end
Normally open then avoids the waste of gas, avoids the loss of heat, ensure that the uniformity of in-furnace temperature, avoids
The waste of fuel.
