Position, two standby positions, such layout standby position only play vacuum tank and hang out/hang in use, and the preheating of vacuum tank is offline arrangement, by two
A standby position is combined into one, and the layout for handling station equipment becomes two vehicles, three station, two processing positions and a standby position, and two
The vacuum tank for handling position, which is replaced, shares a standby position.
The vacuum tank that the dried offline preheating device can complete renovation carries out low temperature drying dehydration, after drying is up to standard
Can direct pre-heating temperature elevation, until the operating temperature (800 ~ 1200 DEG C) of vacuum tank, then the online processing position that enters carries out steel treatment.
With technological progress, the raising of control precision, the drying and preheating rifle after optimized design can be by heat gas, such as:
Combustion gas (COG/NG), oxygen etc. are precisely controlled under small flow and steadily export, make temperature in vacuum tank control≤
600 DEG C, achieve the purpose that vacuum tank is dry, after dry target reaches, the flow for increasing combustion gas implements the preheating liter of vacuum tank
Temperature moves up and down rifle position until reaching the online temperature of vacuum tank, and preheating lance is during heating, and adjustable point periodically adds
The different position of thermal vacuum slot, keeps the temperature of vacuum tank more uniform.
Due to the limitation of production technology, vacuum tank is essentially not allow to replace simultaneously, and therefore, 2 standby positions are closed
And for 1 be it is reasonable and scientific, two vehicles, three station substitution two vehicles, four station save a station space and corresponding steel construction
Investment cost, both saved space, and adapted to the arrangement in small place and save one-time investment.
Working principle of the present invention is as follows:
The equipment that the present invention handles position provides online equipment for vacuum processing of liquid steel, usually reach 80 when vacuum tank handles molten steel ~
Offline maintenance is needed after 100 heats, it, will in steel treatment gap when 4/ second vacuum tank 10 of the first vacuum tank needs offline maintenance
First multifunctional top-gun, 6/ second multifunctional top-gun 12 and 5/ second hot-bending pipe 11 of the first hot-bending pipe are detached from the first vacuum tank 4/ the
Two vacuum tanks 10,3/ second vacuum tank trolley 9 of the first vacuum tank trolley by 4/ second vacuum tank 10 of the first vacuum tank be transferred to
Seat in the plane, 4/ second vacuum tank 10 of the first vacuum tank of driving hanging out repair, by 4/ second vacuum of the first vacuum tank after maintenance
Slot 10 hangs in dried offline preheating device, and the tumble screening cover 21 of shielding cover device of vacuum notch is fastened on the first vacuum tank 4/
At the notch of second vacuum tank 10, rotary drying and preheating device is then returned back into 4/ second vacuum tank 10 of the first vacuum tank
The notch of 4/ second vacuum tank 10 of the first vacuum tank is inserted at notch and by drying and preheating rifle 23 by the through-hole on screening cover 21,
Igniting heating is carried out, is then again hung in 4/ second vacuum tank 10 of the first vacuum tank of preheating temperature (~ 1000 DEG C) up to standard standby
Position 2, then 4/ second vacuum tank 10 of the first vacuum tank is transferred at first by 3/ second vacuum tank trolley 9 of the first vacuum tank trolley
Position/second processing position is managed, then by 5/ second hot bending of 6/ second multifunctional top-gun 12 of the first multifunctional top-gun and the first hot-bending pipe
Pipe 11 is connect with 4/ second vacuum tank 10 of the first vacuum tank again, and first vacuum tank 4 and the second vacuum tank 10 are replaced in turn,
It is mutually non-interference.
Present invention saves place and corresponding steel construction, the layout pattern of two vehicles, three station purifier will handle position cloth
Set in two sides, middle position is standby position, totally two vacuum tank trolleys, two vacuum tanks, three vacuum tank card slots, it is intermediate to
Slot position is hung when seat in the plane is replaced for vacuum tank, the replacement of two sets of vacuum tanks carries out in turn, and interference problem is not present, saves in this way
A standby position can reduce the plane length of 8 ~ 12m, corresponding steel construction amount is saved more, and the auxiliary investment of work greatlys save.
Preheating device and heating device are integrated by dried offline preheating device of the present invention, save space and invest, and adjust
The heat gas of whole preheating lance and oxygen, air proportion, it can be achieved that vacuum tank is dry, the integrated function of pre-heating temperature elevation, two
Covering device is combined into one, and has not only been saved place but also has been saved investment, has saved the operation energy.
Present invention optimizes production technologies, and offline vacuum tank is placed on dried offline preheating device and is carried out, instead of true
3 ~ 5 hours time of the occupied processing position of the online slugging of empty slot, 10% or more processing capacity can be promoted, production is greatly optimized
Technique improves production efficiency.
The preferred embodiment for the present invention is explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Mode within the knowledge of a person skilled in the art can also be without departing from the purpose of the present invention
It makes a variety of changes.
Many other changes and remodeling can be made by not departing from the spirit and scope of the present invention.It should be appreciated that the present invention is not
