Technical field
The utility model belongs to the gas-fired of steel mill vacuum treatment device, technical field of heating, specifically is a kind of in the burner of existing RH (application of vacuum) stove apparatus for baking and the architecture advances of gas distribution station.
Background technology
In the prior art, RH (application of vacuum) stove apparatus for baking is a pith of the complete vacuum treatment device introduced from German DEMAG company, its apparatus for baking is because of the problems in the design, subject matter is that baking temperature is low, the highest position can only reach 830 ℃, and inhomogeneous, 800 ℃ of upper and lower part potential differences; Stoving time is oversize, far can not satisfy the requirement of production technology, and complete set of equipments can't normally be moved, and has caused serious loss.
Summary of the invention
The utility model has solved the technical problem that exists in existing complete set of equipments RH (application of vacuum) the stove apparatus for baking, provides a kind of baking temperature can reach more than 1200 ℃, and end opening insertion pipe can reach RH (application of vacuum) the stove apparatus for baking more than 800 ℃.
The utility model is to realize like this, RH stove apparatus for baking, include burner and gas distribution station, burner contains gas passage and combustion chamber, the bottom of burner is connected with the RH bell, top links to each other with gas distribution station, the top that it is characterized in that burner is provided with inert gas channel, gas passage and oxygen channel, three kinds of gas passages of burner link to each other with nozzle, the top of nozzle is provided with the water cooling chamber, the below is provided with the combustion chamber, and the both sides of combustion chamber are respectively equipped with fire hole and detect the hole, is furnished with electric control valve with the gas distribution station that burner matches, the fast pneumatic stop valve, spark arrester, the pressure transformer.In burner, increase inert gas channel, make burner import high rapid-result high pressure inert gas, increased the motive force of fuel gas, delayed the burning time of oxygen and coal gas, elongated burner flame, satisfied the required heating curve of production technology.
Nozzle of the present utility model is provided with guide vane, makes oxygen be subjected to revolving force and can not mix with coal gas immediately
Three kinds of gas passages of nozzle described in the utility model are concentric, are respectively inert gas, coal gas, oxygen channel from inside to outside.
The main body of the utility model nozzle is welded with heat-resistance stainless steel, long service life, safe and reliable.
It is strong and powerful that the utility model compared with prior art has flame, sprayed the bottom and inserted pipe more than 1 meter, and furnace temperature can reach more than 1200 ℃, and the bottom is inserted pipe and reached more than 800 ℃, and stoving time, heating curve meet production technology and requirement fully.

a, oxygen should be 4000～5000P
a, nitrogen should be 0.3～0.6MP
a, 3, the selector switch of switch board is forwarded to " new bag " or " old bag " or " insulation " position, gauge tap is forwarded to " automatically " position, promptly follow procedure starts operational system automatically: blower fan starting operation → lift bell → open fast pneumatic stop valve (12
1) gas stop valve → open lighting valve, excite light a fire → open oxygen cutting valve (11) and fast pneumatic stop valve (12 simultaneously
2) gas stop valve → open oxygen regulating valve (9) → control valve that turns on the gas-fire (10) → close accent lighting valve → put down bell begins baking.Furnace temperature reaches 1200 ℃ and promptly adjusts two control valves automatically to " insulation " position.
Baking finishes, and closes gas regulator → close oxygen valve → gauge tap is gone to " O " position, and PLC is the halt system operation, closes oxygen and gas stop valve automatically, finishes once baking.
