Abstract
The utility model discloses a kind of blast furnace banking air port sealed structure, relate to metallurgical ironmaking technology field, comprise the water cannon mud layer being embedded in tuyere medium sleeve inner chamber, described water cannon mud layer peripheral hardware plugging plate, described plugging plate and middle cover inner hole and be arranged on middle cover aperture, described plugging plate peripheral hardware yellow mud layer, described yellow mud layer peripheral hardware butter layer.First the little cover in blast-furnace tuyere is disassembled, with the sealing of water cannon mud layer in tuyere medium sleeve, then outside water cannon mud layer, middle cover aperture arranges resistant to elevated temperatures asbestos plate, seal with yellow mud layer outside asbestos plate again, finally at the outer coating butter layer of yellow mud layer, install the intensity that asbestos plate increases sealed structure additional, utilize butter to ftracture to avoid yellow mud, this kind of sealed structure significantly reduces the labour intensity of operator, improves working efficiency.The utility model has that structure is simple, the advantage of good sealing effect, simplifying sealing step, without the need to sending special messenger to patrol and examine again, decreasing the workload of operator.
Description
Technical field
The utility model relates to metallurgical ironmaking technology field.
Background technology
Blast furnace ironmaking is the important step in Iron and Steel Production, and this method is formed by shaft furnace ironmaking development in ancient times, improvement, and blast furnace ironmaking possesses skills, and economic target is good, technique is simple, turnout is large, labor productivity is high, low power consumption and other advantages.Iron Works is in dead banking process, and in order to the calorific loss of multiple wind smoothly and during minimizing banking, the minimizing air output of minimum degree, needs measure bottom house blast inlet being taked to sealing, reduce the burning of coke in blast furnace, preserve heat.Conventional sealing technology is: the little cover in large for wind cinder notch cover, middle cover are unloaded down (Fig. 2) after banking, first with hydrous taphole loam, the wind cinder notch overlapped greatly is sealed tight, thickness is probably at 150 ~ 300mm, use laying fireproof bricks one deck (thickness 345mm) afterwards, finally use yellow mud (stir in yellow mud and have the hemp cut preventing yellow mud from ftractureing) that air port is floating, and per tour sends special messenger to check, and whether yellow mud have crack, as there is crack, mend mud more in time crack is floating, add workman's workload.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the blast furnace banking air port sealed structure of good sealing effect, simplifies sealing step, can greatly reduce workload.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of blast furnace banking air port sealed structure, comprise the water cannon mud layer being embedded in tuyere medium sleeve inner chamber, described water cannon mud layer peripheral hardware plugging plate, described plugging plate and middle cover inner hole and be arranged on middle cover aperture, described plugging plate peripheral hardware yellow mud layer, described yellow mud layer peripheral hardware butter layer.
Preferably, the thickness of described water cannon mud layer in tuyere medium sleeve inner chamber is 200 ~ 300mm.
Preferably, described plugging plate is resistant to elevated temperatures asbestos plate.
Preferably, the thickness of the outer yellow mud layer of described plugging plate is 100 ~ 200mm.
Preferably, the thickness of described butter layer is 5 ~ 10mm.
The beneficial effect adopting technique scheme to produce is: disassembled by the little cover in blast-furnace tuyere, be the water cannon mud layer sealing of 200 ~ 300mm with thickness in tuyere medium sleeve, then outside water cannon mud layer, middle cover aperture arranges resistant to elevated temperatures asbestos plate, be the yellow mud layer of 100 ~ 200mm again at asbestos plate arranged outside thickness, finally outside yellow mud layer, smear the thick butter layer of 5 ~ 10mm, install the intensity that asbestos plate increases sealed structure additional, butter is utilized to ftracture to avoid yellow mud, this kind of sealed structure need not unload middle cover, only unload the sealing that tuyere small sleeve can realize blast-furnace tuyere, significantly reduce the labour intensity of operator, improve working efficiency.The utility model has that structure is simple, the advantage of good sealing effect, simplifying sealing step, without the need to sending special messenger to patrol and examine again, decreasing the workload of operator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of blast-furnace tuyere;
In figure: overlap in 1-, 2-water cannon mud layer, 3-plugging plate, 4-yellow mud layer, 5-butter layer, the little cover of 6-, the large cover of 7-.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of blast furnace banking air port sealed structure as shown in Figure 1, comprise the water cannon mud layer 2 being embedded in tuyere medium sleeve 1 inner chamber, described water cannon mud layer 2 peripheral hardware plugging plate 3, described plugging plate 3 is with middle cover 1 inner hole and be arranged on middle cover 1 aperture, described plugging plate 3 peripheral hardware yellow mud layer 4, described yellow mud layer 4 peripheral hardware butter layer 5.
As a kind of preferred structure, the thickness of described water cannon mud layer 2 in tuyere medium sleeve 1 inner chamber is 200 ~ 300mm, described plugging plate 3 is resistant to elevated temperatures asbestos plate, and the thickness of the outer yellow mud layer 4 of described plugging plate 3 is 100 ~ 200mm, and the thickness of described butter layer 5 is 5 ~ 10mm.
During enforcement, first the little cover 6 in large for blast-furnace tuyere cover 7 is disassembled, seal with the water cannon mud layer 2 that thickness is 200 ~ 300mm in tuyere medium sleeve 1, then outside water cannon mud layer 2, middle cover 1 aperture arranges resistant to elevated temperatures asbestos plate as plugging plate 3, asbestos plate cylindrical and middle cover 1 orifice diameter match, be the yellow mud layer 4 of 100 ~ 200mm again at asbestos plate arranged outside thickness, finally outside yellow mud layer 4, smear the thick butter layer 5 of 5 ~ 10mm, install the intensity that asbestos plate increases sealed structure additional, butter is utilized to ftracture to avoid yellow mud, this kind of sealed structure need not unload middle cover, only unload the sealing that tuyere small sleeve can realize blast-furnace tuyere, significantly reduce the labour intensity of operator, improve working efficiency.
In sum, the utility model has simple, the maneuverable advantage of structure, simplifies sealing step, there will not be yellow mud ftracture and cause air port air intake, sealing effectiveness is good, patrols and examines without the need to sending special messenger again, decrease the workload of operator, there is very strong practicality.
