Abstract
The present invention relates to a movable dustproof hood at a furrow gate of an iron branch furrow of a light-body blast furnace, which comprises a rectangular lattice body moved by one-person operation and used as a structural piece of a main body, wherein the rectangular lattice body as the structural piece of a main body comprises an outer edge frame 1 made of a carbon steel pipe or a stainless steel pipe, a frame 2 made of a thin-wall carbon steel square pipe or/and a thin-wall stainless steel square pipe in the frame 1, a stainless steel sheet 3 coated outside the frame 2, a light heat-insulation material 4 filled in the gap of the frame 2, and a high-temperature bonding agent 5 for bonding the heat-insulation material. The movable dustproof hood has the manufacturing steps: firstly, the frame is made, a lattice frame is made in the frame, and the stainless steel sheet is coated on the surface layer of the frame; the refractory light heat-insulation material is filled in the gap of the frame and is bonded by the high-temperature bonding agent. The shape of the dustproof hood and the sizes of the structural unit of the rectangular lattice body can be flexibly designed according to different field situations so that the dustproof hood can be moved by one-person operation without the influence on the gate building and pulling operation of an iron branch furrow of a blast furnace.
Description
Technical field
The present invention relates to the light height stove of a kind of packaged type iron branck-groove ditch lock place's dw and making method.
Background technology
In the blast furnace ironmaking process, the molten iron in the blast furnace is discharged into earlier in the molten iron tap drain, flows into different Zhigou again, by the ditch lock at different Zhigou place is dialled lock or built lock molten iron is discharged in the iron ladle transport trolley.The ditch lock is made with amorphous refractory materials usually, and middle filling coal dust is so that burning keeps molten iron temperature.Bigger flue dust can be produced when ditch lock and molten iron flow putting through, thereby environmental pollution can be caused.Because the blast furnace blowing that need frequently tap a blast furnace, in order not influence dialling lock, building lock of blast furnace casting, therefore the blast furnace iron branck-groove ditch lock place dust hood of generally not setting up defences causes site environment seriously polluted.
In order to improve the environment at blast furnace iron branck-groove ditch lock place, decontamination alleviates labor intensity of operating staff, thus need design and produce a kind of in light weight, intensity is high, can the be single mobile iron branck-groove that do not influence is built lock, dialled the dw of lock operation.
Summary of the invention
The objective of the invention is to propose the light height stove of a kind of packaged type iron branck-groove ditch lock place's dw and making method in order effectively to solve the existing serious problem of iron work blast furnace iron branck-groove ditch lock place's smoke contamination.
Purpose of the present invention realizes by following proposal: the light height stove of a kind of packaged type iron branck-groove ditch lock place dw, to be these dw operated mobile rectangular grid daughter and formed for the body junction member by single characteristics, the outward flange framework that its rectangular grid phosphor bodies structural part is done by carbon steel pipe or stainless steel tube, the thin-walled carbon square tube of framework inside is or/and the grid skeleton that the thin-wall stainless steel square tube is made, be coated on the stainless steel sheet of this grid skeleton outside, be filled in the interstitial heat-resistant light heat preserving and insulating material of grid skeleton, and the high-temperature agglomerant of this heat preserving and insulating material of bonding constitutes.
The present invention is 1～2mm as the carbon steel pipe of outward flange framework or the wall thickness of stainless steel tube, and diameter is 30～50mm, or 50mm * 25mm * 2mm carbon steel pipe.The thin-walled carbon square tube that is used as the grid skeleton is or/and the thin-wall stainless steel square tube is square carbon steel square tube or the stainless steel tube of 20mm * 20mm * 0.9mm or 30mm * 30mm * 1.0mm.The thickness of described stainless steel sheet is 0.5～1.2mm.Described heat-resistant light heat preserving and insulating material is selected aluminum silicate fiber for use.Described high-temperature agglomerant is selected aluminum phosphate binder for use.
The maximum span of dw of the present invention is greater than the ditch width 30～200mm of iron branck-groove ditch lock place, and the overhead height of dw is 300～650mm, and width is 500～800mm, and thickness is 30～60mm.The shape of dw can be the arch or the shape of a saddle.
The making method step of the light height stove of packaged type of the present invention iron branck-groove ditch lock place dw is:
1st, make the single mobile rectangular grid body structure unit outward flange framework of operating with carbon steel pipe or stainless steel tube, framework inner with the thin-walled carbon square tube or/and the thin-wall stainless steel square tube is made the grid skeleton, and with framework welding formation rectangular grid body structure;
2nd, weld coating at rectangular grid daughter skeleton surface layer with stainless steel sheet;
3rd, toward filling resistant to elevated temperatures light heat insulating material between checker skeleton space, and with the high-temperature agglomerant formation internal layer that bonds, make the single mobile rectangular grid phosphor bodies structural part of operating, the light height stove of recomposition packaged type iron branck-groove ditch lock place dw.
This dw can be according to different its shapes of field condition flexible design and the size dimension of basic structural unit, but so that the one man operation moves, does not influence building lock and dialling lock of blast furnace iron branck-groove ditch lock.
The light height stove of packaged type of the present invention iron branck-groove ditch lock place dw advantage is: 1, because adopted carbon steel pipe or/and stainless steel tube and thin-walled carbon square tube or/and the checker of thin-wall stainless steel square tube structure as agent structure, thereby has reduced the weight of dw effectively; 2, fill resistant to elevated temperatures light heat insulating material in the dw, shielded the thermal radiation effect of molten iron effectively, have energy-conservation, as to reduce site environment temperature effect; 3, this dw can be according to different its shapes of field condition flexible design, the dw good airproof performance, and dustproof effect is good; 4, this dw low price, long service life, can reach more than 1 year duration of service.
