Abstract
The present invention provides the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel, the object of this kind of structure mode is adopted to be make drill steel not bending or few bending when towing, to improve feasibility when mechanize operates, and increase the multiplicity that drill steel uses, reduce the consumption of drill steel, the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel of the present invention, it mainly comprises clamping head, stopping composition in the steel pipe of hollow and hollow steel tube, described clamping head is the holding handle of a power operation, the steel pipe of described hollow is connected with clamping head, described stopping composition is full of and solidifies in the steel duct of whole hollow, stopping composition in hollow steel tube is insulation heat-stable material, can solidify inner in hollow steel tube and there is the characteristic that stronger rigidity is not easily out of shape, according to the not easily deformation characteristic of stopping composition, though there is fusing loss the outside making drill steel, but drill steel can be kept not bend or bend on a small quantity.
Description
Technical field
The present invention relates to metallurgical submerged-arc furnace to come out of the stove equipment, particularly relate to the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel.
Background technology
Mineral hot furnace equipment technology has entered maximization at present, closure, highly automatedization, the epoch of environmental protection and energy saving, the development of new texture and novel process has been strengthened both at home and abroad in mineral hot furnace equipment, and constantly have new Technical investment to use, but furnace of calcium carbide is as traditional highly energy-consuming, heavy polluted industry, its technology is still one of the most backward domestic industry, at present, at home some newly-built and transformation closed calcium carbide furnace on, although being equipped with many modern techniquies, but coming out of the stove in link also almost completely by manual operation, for conventional small-sized non-airtight production, it is abnormal that Influence of production is little that manual operation makes fire door occur, production for large-scale closed type calcium carbide furnace is then different, difficulty is often there will be during manual operation, even accident occurs and affect production, owing to blast-furnace man is being burnt, disclose eye, stifled eye, the operation such as stove eye maintenance is lack of standardization, stove eye can be caused constantly to appear on the stage, furnace bottom is caused to continue to raise, electricity consumption is increased, also can there is fire door, furnace wall, burn-back phenomenon and race eye accident occur, in calcium carbide production process, coming out of the stove is the heaviest operation, also it is most warm work, particularly widen the view, stifled eye is compare dangerous link during calcium carbide is produced when operating, therefore mechanize operation is adopted to be a kind of trend, and drill steel is as disclosing eye and the instrument towed to be born the high temperature of about 2000 DEG C, often therefore bend, thus bring difficulty to mechanize operation, so needing to research and develop a kind of Rod structure mode bending or bending less when towing, to improve the feasibility of mechanize operation.
Summary of the invention
The present invention proposes the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel, the object of this kind of structure mode is adopted to be make drill steel not bending or few bending when towing, to improve feasibility when mechanize operates, and increase the multiplicity that drill steel uses, reduce the consumption of drill steel.
The structure of the present invention forms like this: the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel, it mainly comprises the stopping composition in clamping head, the steel pipe of hollow and hollow steel tube, described clamping head is the holding handle of a power operation, the steel pipe of described hollow is connected with clamping head, and described stopping composition is full of and solidifies in the steel duct of whole hollow.
The object of the present invention is achieved like this: the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel, stopping composition in its hollow steel tube is insulation heat-stable material, can solidify inner in hollow steel tube and there is the characteristic that stronger rigidity is not easily out of shape, when drill steel is towed, drill steel enters the high temperature that furnace chamber bears about 2000 DEG C, drill steel appearance starts to be melted phenomenon, and heat is to drill steel internal delivery, but owing to hollow steel tube inside is insulation heat-stable material, so it is slower to the speed of drill steel internal delivery heat, and drill steel to tow be compare fast, time drill steel inside does not also reach enough hot, drill steel has pulled out outside stove, though therefore drill steel outside place high temperature, but internal temperature is relatively not high, according to the not easily deformation characteristic of stopping composition, though there is fusing loss the outside making drill steel, but drill steel can be kept not bend or bend on a small quantity.
Further, the structure formation of the present invention also can comprise a core bar, core bar is through the inside of whole hollow steel tube and is connected with clamping head, in the space of hollow steel tube tube wall and core bar, it is full of stopping composition and solidifies between hollow steel tube and core bar, a described core bar, it is round steel or Deformed Steel Bars, and the object setting up core bar is the brittle behavior making up stopping composition, stopping composition is not fractureed, so that drill steel is not bent or is bent less.
Accompanying drawing explanation
Fig. 1 is the structural representation of the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel of the present invention.
Fig. 2 is the structural representation containing core bar of the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel of the present invention.
Embodiment
Embodiment one

Embodiment two
See Fig. 2, the structure mode of a kind of Calcium-carbide furnace discharge conveyer drill steel of the present invention, it comprises clamping head 3, the steel pipe 1 of hollow, core bar 4 and the stopping composition between hollow steel tube 1 and core bar 45 with the composition of the drill steel of core bar structure.
Claims (2)
1. the structure mode of a Calcium-carbide furnace discharge conveyer drill steel, it is characterized in that: it mainly comprises clamping head, stopping composition in the steel pipe of hollow and hollow steel tube, described clamping head is the holding handle of a power operation, the steel pipe of described hollow is connected with clamping head, described stopping composition is full of and solidifies in the steel duct of whole hollow, stopping composition is insulation heat-stable material, can solidify inner in hollow steel tube and there is the characteristic that stronger rigidity is not easily out of shape, when drill steel is towed, drill steel enters the high temperature that furnace chamber bears about 2000 DEG C, drill steel appearance starts to be melted phenomenon, and heat is to drill steel internal delivery, but owing to hollow steel tube inside is insulation heat-stable material, so it is slower to the speed of drill steel internal delivery heat, and drill steel to tow be compare fast, time drill steel inside does not also reach enough hot, drill steel has pulled out outside stove, though therefore drill steel outside place high temperature, but internal temperature is relatively not high, according to the not easily deformation characteristic of stopping composition, though there is fusing loss the outside making drill steel, but drill steel can be kept not bend or bend on a small quantity.
