Description
Technical field
Stainless steel converter described in the utility model relates to stainless smelting equipment in a kind of metallurgy industry.
Background technology
At present in converter smelting stainless steel field, oxygen gun blowing by the converter top is smelted, the oxygen consumption is big, and energy consumption is big, the factory building height, investment is big, the oxygen rifle promotes and running gear is on the converter upper stage, and working conditions is abominable, the inconvenience of workman's repair and maintenance, oxygen rifle and rifle head are consumable accessory, strengthen running cost.The stainless steel converter smelting cycle is long, and oxygen blast intensity is big, and lining life is lower, is generally about 100 stoves, for guaranteeing the production operational availability of stainless steel converter, just must change fast furnace shell.The replacing technology of furnace shell mainly contains two kinds at present, a kind of is to adopt U type backing ring, furnace shell connects with adopting 4 pairs 8 swing bolts being connected of backing ring, when changing furnace shell, utilize under the stove jacking car to hold up furnace shell and open joint bolt, the jacking car is transported to furnace shell and is changed the position under the stove, utilize overhead traveling crane to realize the replacing of furnace shell, though simple in structure, in light weight, apparatus processing, making are relatively easily, facility investment is less, but obligatory point is many during the furnace shell expanded by heating, and thermal stresses is higher relatively, shell deformation is bigger, and the life-span is relatively low.U type backing ring, an end opening, under equal section, poor rigidity, the backing ring internal stress is higher, and opening end forms local cantilever beam structures, and stress deformation is bigger.Need like this to increase the backing ring section, influence the body of heater heat radiation, the furnace shell surface temperature raises, and has strengthened shell deformation.Another kind is to adopt integral ring, and furnace shell adopts the fluid pressure type fast assembling-disassembling to connect with being connected of backing ring, and all on transport trolley, transport trolley transports the smelting station with converter integral body to whole revolving furnace body part, utilizes the overhead traveling crane furnace shell that hangs out, packs into.Because of the employing integral ring, good rigidly, the backing ring internal stress is less, can correspondingly reduce the backing ring end face, increases the body of heater surface radiating, and the furnace shell surface temperature is reduced, and has reduced shell deformation, improves the furnace shell life-span.Complex structure, weight is big, and equipment making processing relative difficulty is big, and cost of investment is higher.At existing problem in the above-mentioned prior art, a kind of novel stainless steel converter of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel stainless steel converter of research and design, thereby solves the whole inconvenient maintenance of body of heater, the smelting of furnace roof oxygen gun blowing, and the oxygen consumption is big, energy consumption is big, the factory building height, investment is big, and the oxygen rifle promotes and running gear is on the converter upper stage, working conditions is abominable, the inconvenience of workman's repair and maintenance, oxygen rifle and rifle head are consumable accessory, strengthen problems such as running cost.Stainless steel converter described in the utility model is made up of body of heater, backing ring, tiling arrangement and piping system.Its structure is that body of heater is made up of furnace crown, furnace shell middle part and furnace bottom three parts.Furnace crown and furnace shell middle part is connected by flange, and the furnace shell middle part leans on the furnace bottom coupling device integrator with furnace bottom, and body of heater links together by furnace shell backing ring coupling device and backing ring, backing ring by inboard bearing and non-drive side bearing fixing on the basis.The furnace bottom bottom is provided with bottom blowing system, and is connected with the driving side swivel joint with the non-drive side swivel joint respectively by pipeline.Backing ring described in the utility model is made of integral body, and tiling arrangement is suspended on the driving side gudgeon of backing ring, and backing ring drives furnace shell can do positive and negative 360 ° of revolutions.Bottom blowing system described in the utility model is connected with the driving side swivel joint with the non-drive side swivel joint respectively by pipeline, respectively has a pipeline to be connected with outside switched system.
Stainless steel converter described in the utility model, tiling arrangement drives furnace crown, furnace shell middle part and the furnace bottom revolution of body of heater by backing ring, finish converter tapping, deslagging, thermometric sampled functions, be blown into Sweet natural gas and oxygen steelmaking by driving side swivel joint, non-drive side swivel joint and bottom blowing system at furnace bottom, blowing argon gas and nitrogen stir.This converter is blown Sweet natural gas and is smelted, and comburant oxygen has reduced the running cost of converter, energy efficient, general energy efficient about 50%.Top oxygen gun is not established in this converter, adopts bottom blowing steel-making fully, has reduced factory building height, reduces construction investment, has avoided the repair and maintenance inconvenience to the oxygen gun system.Bottom blowing system adopts outside the switching, all only is furnished with a vent line in the gudgeon of both sides, has reduced the manufacturing and the maintenance difficulties of equipment.Body of heater is made up of furnace crown, furnace shell middle part and furnace bottom three parts, when body of heater is changed, utilize the furnace bottom lift cart that body of heater is changed, but integral replacing also can be changed respectively to furnace crown and furnace bottom.The utlity model has novel structure, improved the utilization ratio of furnace lining, reduced furnace shell and changed the time, improve operating rate, reduce advantages such as running cost, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
