Description
Technical field
The invention belongs to steelmaking technical field, particularly a kind of molten iron transports online hot-metal bottle and adds a cover heat preserving method.
Background technology
The big-and-middle-sized iron and steel enterprise of iron and steel manufacturing industry molten iron means of transportation mainly contains the torpedo tank car means of transportation and directly adopts hot-metal bottle to transport blast-melted " one jar on earth " means of transportation at present.The torpedo tank car transportation is a kind of molten iron means of transportation of comparative maturity, through years development, have advantages such as maneuverability, good heat insulating, good stability, but the transportation of molten iron from blast furnace to converter, process procedure is more, and has gap with high benefit, low energy consumption target that modern metallurgical process technology is pursued.
" one jar on earth " technology is adopted at the blast furnace-converter interface, refer to cancel traditional torpedo tank car, directly adopt hot-metal bottle transportation molten iron, accept, transport, cushion storage, molten iron preliminary treatment, converter to convert multinomial function collection such as iron and hot-metal insulating be one blast-melted.Adopt " one jar on earth " molten iron transportation technology, can cancel steelshop molten iron tank switching station, reduce the operation of a molten iron tank switching, have characteristics such as shortened process, compact total figure layout, also capable of reducing energy consumption, reduce iron loss, reduce smoke contamination, produce bigger economic benefit and social benefit.
" one jar on earth " technology is subjected to the attention of steel plant more and more now, and particularly feasibility and the reliability of molten iron transportation " a jar on earth " all can actively be investigated, be proved to newly-built steel plant project.At present, the successful Application of large-scale steel plant of domestic several families " a jar on earth " technology has greatly inspired the iron and steel manufacturing industry further to apply the confidence of this technology.
Blast furnace production is to be interrupted to supply with to steelshop supply molten iron, go out general 2～5 jars of iron flask number at every turn, the canful hot-metal bottle needs to wait for certain hour in molten iron transportation railway line that the general stand-by period is between 30～60min, and is longer sometimes after being transported into steelshop together.Because hot-metal bottle jar mouth is big, the molten iron heat radiation is very fast, 0.6～1.0 ℃ of per minute kind.Hot-metal bottle is waiting 18～60 ℃ of the meeting coolings of biding one's time like this.For the pneumatic steelmaking factory of millions of tons of annual productions, the thermal loss of molten iron is huge.In steelmaking technical field, reducing thermal losses is one of energy-saving and cost-reducing important technology economic indicator of steel mill, but steel plant transport method and the measure that hot metal temperature drop does not also have simple and feasible to molten iron at present.
Summary of the invention
The object of the present invention is to provide a kind of molten iron to transport online hot-metal bottle and add a cover heat preserving method, solved the huge problem of thermal loss in the molten iron transportation that prior art exists, realized insulation simple to operate, esy to use, safe and reliable.
The present invention arranges hot-metal bottle at steelshop hot-metal bottle transport vehicle diamond molten iron transportation railway line side to add a cover attemperator, realizes the insulation to molten iron in the hot-metal bottle, reduces hot metal temperature drop.Can add a cover attemperator and realize a plurality of hot-metal bottles that enter steelshop are added a cover insulation by many hot-metal bottles are set at many hot-metal bottle transport vehicle sides.
Facility of the present invention comprises: molten iron transportation railway line, hot-metal bottle transport vehicle, hot-metal bottle, hot-metal bottle are added a cover attemperator; Hot-metal bottle is added a cover attemperator be arranged in molten iron transportation railway line side, the hot-metal bottle on the molten iron transportation railway line is added a cover insulation; Hot-metal bottle is added a cover the attemperator basis and is transported railway line on same plane with molten iron, all is positioned on the steelshop terrace.Add a cover insulation by arrange online add a cover that attemperator realizes a plurality of hot-metal bottles online of many hot-metal bottles at molten iron transportation railway line side.Capping step is as follows:
At first, the hot-metal bottle that the molten iron transport vehicle will be filled molten iron is accommodated to corresponding hot-metal bottle capping device position, afterwards, by operating desk operation control insulation cover lift drive mechanism the hot-metal bottle insulation cover being descended by the Field Force adds a cover to hot-metal bottle, molten iron is incubated; When steelshop needs the handling molten iron, again the hot-metal bottle insulation cover is rotated up 85o and open the hot-metal bottle insulation cover, in order to hot-metal bottle is hung out; After the hot-metal bottle of turned letter is back on the molten iron transport vehicle, add a cover insulation to hot-metal bottle again.When hot-metal bottle need transport steelshop, after again the hot-metal bottle insulation cover being opened, can transport.
Described hot-metal bottle is added a cover attemperator and is made up of hot-metal bottle insulation cover, insulation cover lift drive mechanism, insulation cover lifting support, steel wire rope and assembly pulley.The insulation cover lift drive mechanism is located on the insulation cover lifting support, is positioned at its underpart; The lifting rotating shaft of hot-metal bottle insulation cover is connected with the rotation axis support at insulation cover lift drive mechanism top, and the insulation cover lift drive mechanism is realized the lifting of hot-metal bottle insulation cover by steel wire rope and assembly pulley.Described insulation cover lift drive mechanism is made up of motor, reductor, brake, reel.Motor is connected with input shaft of speed reducer, and reel is connected with the output shaft of decelerator, and brake is positioned on the input shaft of speed reducer.
By the insulation cover lift drive mechanism realize to the hot-metal bottle insulation cover add a cover and take off lid, the hot-metal bottle insulation cover lifting anglec of rotation is 0～85o.
Described hot-metal bottle tank body geometry has two kinds: a kind of is at the bottom of truncated cone tank body, the circular horizontal retort and duckbill is converted embolum; Another kind is at the bottom of circle tube tank body, the hemispherical jar and duckbill is converted embolum.
Described hot-metal bottle is added a cover the cover lifting rotary manipulation control of attemperator and is finished by the manual operation of execute-in-place platform, also can adopt the operating room centralized Control.
Described hot-metal bottle is added a cover attemperator and not only the hot-metal bottle that molten iron is housed from blast furnace is added a cover insulation, and can carry out the insulation of adding a cover of slack tank to having converted the empty hot-metal bottle that molten iron returns on the hot-metal bottle transport vehicle, to reduce the temperature drop of slack tank.
Result of use of the present invention:
By the hot-metal bottle on the molten iron transport vehicle that enters steelshop is added a cover, realize the insulation of adding a cover of hot-metal bottle canful and slack tank, can reduce hot-metal bottle because waiting as long for a large amount of thermal losses that cause, fully improve the service efficiency of molten iron physics heat, the addition of steel scrap in the pneumatic steelmaking metal charge is improved, reduces production costs.
After hot-metal bottle is added a cover insulation, the temperature drop of canful molten iron can reduce～0.3 ℃/min, if the hot-metal bottle stand-by period on the molten iron supply line on average presses 50min and calculates, add a cover insulation so and can reduce hot metal temperature drop～15 ℃, amount to converter ton steel and reduce hot metal ratio～7.5kg/t steel, calculate the ton steel by this and can eat steel scrap 6kg more, the energy-conservation 0.5kg mark of ton steel coal.In addition, the slack tank hot-metal bottle is added a cover insulation can reduce the slack tank liner and dispel the heat in a large number, reduce hot metal temperature drop, reduce the ladle lining loss, further reduce production costs.
