Abstract
The utility model discloses a steelmaking converter tapping hole reaming instrument, including boring the body, the ditch back of the body, slot, blade holder, blade and drill bit and drill bushing, it is the big cone of the little rear end of point diameter diameter to bore the body, be equipped with the spiral ditch back of the body and slot in the cone, the cross section of the spiral ditch back of the body and slot is arc, blade holder equipartition that the top surface was equipped with the blade in spiral ditch back. The spiral ditch back of the body, slot that the toper was bored on the body are 2 or 3. The utility model has the advantages of it is effectual high with remediation efficiency to arrange the sediment.
Description
Technical field:
The utility model relates to a kind of instrument, in particular for the reaming tool repaired steel tapping hole for steel making converter.
Background technology:
Steel tapping hole for steel making converter affects molten steel because the slag in molten steel condenses upon tap hole wall, need often to repair tap hole, conventional method blows burning with coal gas oxygen population to tap hole wall, remove the slag that mouth wall condenses, make steel mouth return to the hole normally going out molten steel, because in situ temperature is high, severe operational environment, time are long, occur blowing burning area by workman's level excessive, even furnace wall is burnt out, affect the life-span of converter.In order to overcome the defect that this method exists, adopt mechanical hole reaming instrument, but at reaming procedure, this reaming tool occurs that deslagging is not smooth, reaming efficiency is low, and the hole enlarger activity duration extends, and causes hole enlarger to lose efficacy, have impact on work-ing life, considerably increase maintenance cost.
Summary of the invention:
The utility model object is to provide the steel tapping hole for steel making converter reaming tool that a kind of deslagging is smooth and easy, remediation efficiency is high.
The technical scheme realizing the utility model object is, a kind of steel tapping hole for steel making converter reaming tool, comprise drill body, the ditch back of the body, groove, tool rest, blade and drill bit and drill bushing, it is characterized in that: described drill body is the cone that point diameter little rear end diameter is large, described cone is provided with the volution ditch back of the body and groove, the cross section of the described volution ditch back of the body and groove is circular arc, and the tool rest that end face is provided with blade is distributed in described volution ditch back.The volution ditch back of the body on described taper drill body, groove are 2 or 3.
The utility model has the advantage that deslagging is effective and remediation efficiency is high compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is perspective view of the present utility model.
Embodiment:
The structure of existing machinery reaming tool is, cross section is three ribs, groove is formed between rib, the described rib back of the body and groove are being axially the straightedge back of the body and straight flute, rib back is evenly equipped with tool rest, and blade is located on the end face of tool rest, is provided with drill bit at the front end of reaming tool, establish drill bushing in the rear end of reaming tool, this drill bushing is provided with connecting hole and driver slot.To the analysis and research of above-mentioned existing reaming tool, the not smooth reason of its deslagging is the rib back of the body and groove is that axial straightedge is carried on the back and straight flute causes, for the defect of said structure, the utility model adopts following technical proposals, reaming tool is made the little and cone that rear end diameter is large of point diameter, this cone is established volution ditch carry on the back 2, groove 3, tool rest 4 with blade 5 is distributed on the end face of the described ditch back of the body, the described ditch back of the body, the cross section of groove is circular arc, this arc-shaped structure can strengthen the strength and stiffness of the ditch back of the body, deslagging can be made again more smooth and easy, because groove is spirrillum, the slag cut down is in the trench with the end thrust effect that the hand of spiral produces, slag just ejects smoothly, overcome the defect that deslagging has some setbacks.The front end drill bit 1 that the utility model adopts, tool rest and blade and rear end drill bushing 6 are same as the prior art.
Claims (2)
