Abstract
The invention provides a structure of a drill rod for a calcium carbide furnace discharge conveyer. By the adoption of the structure, the drill rod can not be bent or is bent slightly during pulling, so that the feasibility of mechanical operation is improved, the service life of the drill rod is prolonged, and drill rod consumption is reduced. The structure mainly comprises a clamping head, a hollow steel tube and filler arranged in the hollow steel tube, wherein the clamping head is a clamping handle for mechanical operation, the hollow steel tube is connected with the clamping head, the whole hollow steel tube is filled with the filler which is in a solidified state, and the filler is a heat-insulating and heat-resisting material, can be solidified in the hollow steel tube and is high in rigidity and not prone to deformation. Due to the fact that the filler is not prone to deformation, the drill rod can not be bent or is bent slightly even if fusion loss occurs outside the drill rod.
Description
Technical field
The present invention relates to metallurgical submerged-arc furnace to come out of the stove equipment, particularly relate to a kind of frame mode of Calcium-carbide furnace discharge conveyer drill steel.
Background technology
Mineral hot furnace equipment technology enters maximization at present, closure, increasingly automated, the epoch of environmental protection and energy saving, the development of new construction and new technology 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 be equipped with many advanced technologies, but come out of the stove also almost complete in manual operation in link, for small-sized unsealed production in the past, it is abnormal little to Influence of production that manual operation makes fire door occur, production for large-scale closed type calcium carbide furnace is then different, often difficulty is there will be during manual operation, even there is accident and affect production, because 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, power consumption is increased, also fire door can be there is, furnace wall, burn-back phenomenon and race eye accident occur, in calcium carbide production process, coming out of the stove is operation the heaviest, also be most warm work, particularly widen the view, it is link more dangerous during calcium carbide is produced during stifled eye operation, therefore mechanized operation is adopted to be a kind of trend, and drill steel is as the high temperature disclosing eye and the instrument of towing and will bear about 2000C °, often therefore bend, thus bring difficulty to mechanized operation, so need to research and develop a kind of Rod structure mode bending or bending less when towing, to improve the feasibility of mechanized operation.
Summary of the invention
The present invention proposes a kind of frame mode of Calcium-carbide furnace discharge conveyer drill steel, the object of this frame mode is adopted to be make drill steel not bending or few bending when towing, to improve feasibility during mechanized operation, and increase the number of repetition of drill steel use, reduce the consumption of drill steel.
Structure of the present invention forms like this: a kind of frame mode of Calcium-carbide furnace discharge conveyer drill steel, it mainly comprises the inserts in clamping head, the steel pipe of hollow and hollow steel tube, described clamping head is a mechanically operated holding handle, the steel pipe of described hollow is connected with clamping head, and described inserts is full of and solidifies the steel duct in whole hollow.
The object of the present invention is achieved like this: a kind of frame mode of Calcium-carbide furnace discharge conveyer drill steel, inserts in its hollow steel tube is thermal-insulation heat-resistant material, can solidify in hollow steel tube inside and there is the on-deformable characteristic of stronger rigidity, when drill steel is towed, drill steel enters the high temperature that furnace chamber bears about 2000 C °, drill steel appearance starts to be melted phenomenon, and heat is to drill steel internal delivery, but because hollow steel tube inside is thermal-insulation heat-resistant material, so slower to the speed of drill steel internal delivery heat, and drill steel to tow be more 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 inserts, though make the outside of drill steel have fusing loss, but drill steel can be kept not bend or bend on a small quantity.
Further, version of the present invention also can comprise a core bar, core bar through whole hollow steel tube inside and be connected with clamping head, in the space of hollow steel tube tube wall and core bar, be full of inserts and solidify between hollow steel tube and core bar, a described core bar, it is round steel or screw-thread steel, and the object of setting up core bar is the brittle behavior making up inserts, inserts is not fractureed, thus makes drill steel not be bent or be bent less.
Accompanying drawing explanation
Fig. 1 is the structural representation of the frame 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 frame mode of a kind of Calcium-carbide furnace discharge conveyer drill steel of the present invention.
