Description
Technical field
The utility model relates to a kind of blast furnace refrigerating unit, belongs to the smelting industry mechanical equipment technical field.
Background technology
Metallurgy industry, blast furnace cooling apparatus are the important component parts of blast furnace structure, mainly are made up of cooling plate and cooling stave.Cooling stave leans on the furnace shell side to be cast into weldless steel tube, and the ironcasting that leans on the stove inboard to be cast into or to be bumped into refractory body claims to inlay the brick cooling stave, does not inlay the title light face cooling stave of brick.The material of cooling stave, the cooling stave of furnace bottom, cupola well and shaft middle and upper part generally adopts regular gray iron, and bosh, furnace bosh and restoration of lower stack adopt ferrite ductile cast iron or heat-resistant low-chromium cast iron etc.The cooling plate material is cast copper, cast iron or cast steel, and interior type is cavity, is with dividing plate or is cast into weldless steel tube.Effect mainly contains following several respects to cooling apparatus to body of heater: (1) is taken away the heat of high temperature that spreads out of in the stove through cooling apparatus, thereby reaches the effect of protection furnace shell; (2) surface Working Temperature of the refractory materials in blast furnace reaches about 1500 ℃, if there is not cooling apparatus, refractory materials will be etched or wear and tear at short notice.Under the protection of cooling apparatus, can improve the anti-erosion and the antiwear property of refractory materials.(3) when the refractory materials major part or after all being etched, lean on the slag crust on the cooling apparatus to continue to keep blast furnace production.Along with improving constantly of combustion intensity, the erosion of refractory materials is than very fast, less than a generation during furnace life cooling stave will come out.In case erosion damage appears in cooling stave, cooling stave will stop to supply water here, and casing temperature will sharply rise, and occurs furnace shell rimose potential safety hazard easily.Blast furnace production will receive serious threat, occurs security incident easily.
The utility model content
The utility model purpose provides a kind of blast furnace refrigerating unit, replaces cooling stave work, solves the problems referred to above that exist in the background technology.
The technical scheme of the utility model is: the blast furnace refrigerating unit; Comprise gland, water jacket, seat ring, water inlet pipe, rising pipe, the water jacket two ends are installed between gland and the seat ring, and water inlet pipe and rising pipe pass from gland respectively; Water inlet pipe to water jacket bottom, rising pipe is to water jacket top.
Water jacket outer rim both sides are connected fixing with seat ring, gland through bolt, be provided with packing ring between water jacket and gland, the seat ring.
The beneficial effect of the utility model is: can prolong blast furnace cooling apparatus work-ing life, improve cooling performance, prolong the blast furnace overhaul cycle.Help stablizing blast furnace production and operation, for the high and stable yields of blast furnace provide powerful guarantee.Have characteristics simple in structure, easy for installation, safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1. gland, 2. packing ring, 3. seat ring, 4. water jacket, 5. water inlet pipe, 6. nut, 7. bolt, 8. rising pipe.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
With reference to accompanying drawing 1, the blast furnace refrigerating unit comprises gland 1, packing ring 2, seat ring 3, water jacket 4, water inlet pipe 5, nut 6, bolt 7, rising pipe 8.Its middle washer adopts the copper sheet processing and fabricating, and red copper has plasticity preferably, can guarantee sealing; Water jacket adopts the casting red copper material, and red copper has good thermal conductivity, can realize abundant cooling.Two in the hole of two 1 writing brushes of processing size is respectively applied for and is installed into water pipe and rising pipe on gland.Water inlet pipe reaches the water jacket bottom, and rising pipe is on water jacket top.On gland and seat ring flange face, all be processed with groove, not only help washer sealing but also play the fixedly effect of water jacket.Seat ring need be opened a hole with cooling stave when mounted, the seat ring bottom is welded to the last furnace shell outside fixes.Elder generation on water jacket, advanced gasket sleeve in the cooling stave with water jacket then after seat ring fixed, and water jacket outer rim back cushion circle and seat ring seal.Gland needs to install after welding fixes with rising pipe with water inlet pipe earlier, between gland and water jacket outer rim, needs fill up upper gasket and seals.At last, gland, packing ring, water jacket, seat ring are compressed each other with bolt 7, nut 6, so as not to occur leaking, gas leak phenomenon.In addition, the water jacket front end is thickeied processing when making, and mainly is in order to prolong water jacket work-ing life, and the water jacket end is exposed in the stove, directly contacts high temperature and is etched easily, and the front end thickening can increase corrosion resistance.Water inlet pipe and rising pipe upper end all are processed with pipe-thread, and rapid-acting coupling is installed respectively, connect the body of heater water-cooled tube.Water coolant arrives the water jacket bottom, springs back over water jacket top then, is flowed out by rising pipe.Circulation reaches the refrigerative effect so repeatedly.Thereby play the effect of protection cooling stave and furnace shell.Help prolonging cooling apparatus work-ing life, help stablizing blast furnace production and operation, for the high and stable yields of blast furnace provide powerful guarantee.
Claims (2)
1. blast furnace refrigerating unit; It is characterized in that comprising gland (1), seat ring (3), water jacket (4), water inlet pipe (5), rising pipe (8); The water jacket two ends are installed between gland and the seat ring; Water inlet pipe and rising pipe pass from gland respectively, water inlet pipe to water jacket bottom, and rising pipe is to water jacket top.
2. the blast furnace refrigerating unit according to claim 1, it is fixing to it is characterized in that water jacket outer rim both sides are connected with seat ring (3), gland (1) through bolt (7), is provided with packing ring (2) between water jacket and gland, the seat ring.
