Abstract
The utility model provides a reamer for a converter dismantling car. The reamer comprises a reamer rod and a drill which is sleeved on the reamer rod, wherein the reamer rod comprises a loop bar head, a rod body, and a loop bar tail; the drill is sleeved at one end of the loop bar head through a drill pin; the other end of the loop bar head is sleeved at one end of the rod body through a rod head pin; and the loop bar tail is sleeved on the other end of the rod body through a rod tail pin. Compared with the prior art, the reamer provided by the utility model has the advantages that the operation time of the converter dismantling car is reduced to 5-6 minutes from about an hour in the past in replacing a tap hole; the reamer is convenient to install and maintain; and the labor intensity of a worker is reduced.
Description
Technical field
The utility model relates to the replacing of steel tapping hole for steel making converter, is specifically related to a kind of hole enlarger of converter when tearing the stove car open and carrying out the steel tapping hole replacement operation.
Background technology
Converter is the major equipment of STEELMAKING PRODUCTION, tap hole in converter is in order to tap and to slag tap on time, it is fired and is formed by refractory materials, because tap hole often is subject to the erosion of high-temperature molten steel and slag, will be due to scaling loss after converter smelting arrives certain stove number, the reasons such as residual steel, residue obstruction need to change.The traditional way of changing is to load onto hole enlarger at the front end of tearing stove car owner arm open with bolt, relies on the rotation of principal arm and stretches to bore and expand operation, and drilling like this tap hole needs one hour, consuming time longer, has a strong impact on the rhythm of production of converter steelmaking.
Summary of the invention
The purpose of this utility model is to provide a kind of special-purpose hole enlarger required when for converter, tearing the stove car open and change the tap hole operation, can complete in the short period of time the replacing tap hole, meets the needs of steel-making fast pace safety in production.
For achieving the above object, technical scheme provided by the utility model is: the automobile-used hole enlarger of stove is torn in a kind of converter open, it includes the hole enlarger bar and is sleeved on the drill bit on the hole enlarger bar, described hole enlarger bar includes loop bar head, shaft, loop bar tail, wherein, drill bit is sleeved on the first end of loop bar by bit finger, and the loop bar head the other end is sleeved on shaft one end by gudgeon-pin, and the shaft the other end is set with the loop bar tail by the bar end pin.
Described drill bit includes drill bit shaft and is distributed on some blades on the drill bit shaft axle body along axle center, between adjacent knife blades, by dowel, connects.
Described shaft adopts thick-walled seamless steel pipes to make moulding.
Described loop bar tail adopts alloy tool steel to make moulding.
The utility model is compared with conventional art, and advantage is:
The first, change a tap hole, the activity duration of disassembling furnace machine was reduced to 5-6 minutes by original about 1 hour;
The second, hole enlarger installation and maintenance are all very convenient, have reduced labor strength.
Three, the hole enlarger activity duration shortens greatly, has saved to tear the stove turner open and make required fuel oil.
Four, hole enlarger extends work-ing life, has saved cost.
The accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is drill bit schematic diagram of the present utility model.
Fig. 3 is that A in Fig. 2 is to schematic diagram.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: referring to accompanying drawing 1 to accompanying drawing 3, the described hole enlarger of the present embodiment includes hole enlarger bar 2 and is sleeved on the drill bit 1 on hole enlarger bar 2, described hole enlarger bar 2 includes loop bar head 4, shaft 5, loop bar tail 6, wherein, the hole enlarger shaft of the present embodiment takes φ 137 * 16 thick-walled seamless steel pipes to make moulding.The bar head adopts No. 45 steel to process.The bar tail, because work will contact with hydraulic hammer internal piston bar the time, adopts 35Cr alloy tool steel making moulding.Drill bit 1 includes drill bit shaft 9 and is distributed on the some blades 11 on drill bit shaft 9 axle bodies along axle center, between adjacent knife blades 11, by dowel 10, connect, drill bit shaft 9 is sleeved on loop bar head 4 one ends by bit finger 3, loop bar head 4 the other ends are sleeved on shaft 5 one ends by gudgeon-pin 7, and shaft 5 the other ends are set with loop bar tail 6 by bar end pin 8.Hole enlarger is contained in to be torn open on stove car hydraulic hammer, relies on the surging force of hydraulic hammer and the rotation of tearing stove car owner arm open during work, and the drill bit of hole enlarger front end completes the operation to tap hole.This structure is installed, convenient disassembly, through practice, uses, and has greatly shortened the time of changing tap hole, has reduced cost, for the safety in production of converter steelmaking fast pace provides powerful guarantee.
The embodiment of the above is only the preferred embodiment of the utility model, not with this, limits practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
