Description
Technical field
The utility model relates to stainless smelting equipment in a kind of metallurgy industry, relates in particular to a kind of stainless steel grate.
Background technology
In grate smelting stainless steel field, lean on the oxygen gun blowing of grate top to smelt at present, the oxygen consumption is big; Energy consumption is big, and factory building is high, and investment is big; The oxygen rifle promotes and running gear is on the grate 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.Stainless steel grate 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 grate, just must change fast furnace shell.The replacing technology of furnace shell mainly contains two kinds at present, and a kind of is to adopt U type backing ring, and furnace shell connects with adopting 4 pairs 8 swing bolts being connected of backing ring; When changing furnace shell, utilize that the jacking car holds up furnace shell and opens joint bolt under the stove, 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, make relatively easily, facility investment is less, but obligatory point is many during the furnace shell expanded by heating; Thermal stresses is higher relatively, and 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 grate integral body to whole grate 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.Simultaneously in smelting process, often body of heater takes place with backing ring moves, bolt is formed impact, the inefficacy of bolt fasteners fatiguability causes the generation of security incident.
Summary of the invention
The purpose of the utility model provides a kind of stainless steel grate, thereby solves the inconvenience of body of heater overall maintenance, improves the mode of connection of stainless steel grate and backing ring, in the work-ing life of improving bolt fasteners, eliminates safe hidden trouble.
The utility model is realized through following technical scheme:
The stainless steel grate is made up of body of heater, backing ring, tiling arrangement and piping system, and described body of heater is made up of furnace roof, furnace bosh and furnace bottom; Described furnace roof, furnace bosh and furnace bottom are connected in aggregates; Described furnace bosh is connected with backing ring, and described backing ring is connected with tiling arrangement, and described furnace bottom bottom is provided with bottom blowing system; Described bottom blowing system is connected through the outside switched system of pipeline; Described furnace bosh and backing ring are correspondingly provided with the bolt bearing respectively, and furnace bosh is connected through bolt with backing ring, also are provided with preset pieces between described furnace bosh and the backing ring.
Described tiling arrangement is fixedly connected with backing ring through turning axle, and backing ring drives body of heater can do positive and negative 360 ° of revolutions.
The utility model stainless steel grate, tiling arrangement turns round through the body of heater that backing ring drives body of heater, accomplishes grate tapping, deslagging, thermometric sampled functions; Bottom blowing system is arranged on furnace bottom; Reduced the running cost of grate, energy efficient, general energy efficient about 50%.This grate is not established top oxygen gun, 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, has reduced the manufacturing and the maintenance difficulties of equipment.Body of heater is made up of furnace roof, furnace bosh 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 roof 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.Be provided with preset pieces between body of heater of the utility model and the backing ring, solved the problem that body of heater and backing ring are moved in smelting process, alleviated impact, improved the work-ing life of bolt fasteners, eliminated the potential safety hazard in the production process bolt.
