Abstract
The utility model relates to a drill tool, in particular to a tapping drill tool of the blast furnace for the metal melting, which is a hard alloy cross brazing sheet for the tapping drill tool of the blast furnace. The hard alloy cross brazing sheet comprises a drill bit body and the hard alloy cross brazing sheet welded and fixed on the drill bit body, wherein a mounting groove is arranged on the drill bit body; a crimping groove with a large inner part and a small outer part is arranged on the drill bit body; the shape of the head part of the hard alloy cross brazing sheet is same as and matched with shape of the section of the mounting groove; and the head part of the hard alloy cross brazing sheet is inserted, welded and fixed in the mounting groove of the drill bit body. The utility model improves the work efficiency of the drill bit and prolongs the service life of the drill bit.
Description
Technical field
The utility model relates to a kind of drilling tool, and particularly a kind of Metal smelting blast furnace opening drilling tool relates in particular to Wimet cross pricker sheet blast furnace opening drilling tool.
Background technology
At present in metallurgical industry blast furnace ironmaking process, the molten iron mouth stops up with no bubble mud, its hardening of high temperature sintering through several hrs, need adopt the tapping outlet rig to incite somebody to action, and sintering mud bubble drills, flow out molten iron, usually adopt the tapping outlet rig to drill the shutoff blast furnace iron notch, its boring bar tool should adapt under the hot environment and uses, and the hole depth of the stream iron mouth of blast furnace is generally 2.5 meters to 4 meters, when fire door drills soon, drill bit is near burner hearth 0.2-0.5M place, the fast temperature of opening place, iron hole when boring saturating blast furnace is up to 800～1100 ℃, is about to when drilled at the iron oral pore, and temperature is up to more than 1200 ℃, when brill blocked up the mud hole thoroughly, drill bit may dissolve in molten steel.Tapping outlet rig drill bit commonly used is a steel head hard-face bit, is made up of bit matrix and the brazing sheet of hard alloy that is fixed on the bit matrix, and the bit matrix material is difficult to tolerate above-mentioned high temperature, and brazing sheet of hard alloy easily comes off.The major cause that causes brazing sheet of hard alloy to come off is that the shape of the cross pricker sheet of Wimet is too simple, as the structure of the cross pricker sheet of employed Wimet in the prior art usually as shown in Figure 1, its bottom surface and side are the plane, mode by welding is fixed on the drilling tool matrix, have following problem: the blast furnace opening bores the body of work regional centralized in the brazing sheet of hard alloy position, the pricker sheet is only fixing by the mode and the matrix welding of brazing, spelter solder fusing point used when itself and matrix weld has only 930 degrees centigrade usually, the blast furnace opening bores and at high temperature works for a long time, after the spelter solder fusion, the pricker sheet directly comes off from matrix, can't adapt to the open-work needs.In use a drill bit can't independently be finished drilling of a hole, needs several drill bits just can drill the oral pore that taps a blast furnace sometimes, and drilling life of bit is too short, and drill bit consumption is too high.
Summary of the invention
The purpose of this utility model is the deficiency at prior art, provide a kind of Wimet cross pricker sheet blast furnace opening to bore, its brazing sheet of hard alloy can be good with matrix bond, prevents that brazing sheet of hard alloy from coming off from matrix, improve drilling life of bit, reduce the drill bit consumption of blast furnace opening.
The technical solution of the utility model is:
A kind of Wimet cross pricker sheet is used for the blast furnace opening and bores, comprise drill body and the cross pricker sheet of Wimet that is fixedly welded on the drill body, described drill body is provided with mounting groove, it is characterized in that: described mounting groove be in big outer tight mouthful of little groove, the cross pricker sheet of described Wimet head shape and mutual coupling identical with the mounting groove cross-sectional shape, the intercalation of the cross pricker sheet of described Wimet head is fixedly welded on mounting groove on the drill body.
As to further improvement of the utility model, the cross section of described mounting groove is the T type, and the head cross section of the cross pricker sheet of described Wimet is the T type.
As to further improvement of the utility model, the boss width B that described Wimet cross pricker sheet head stretches out Wimet cross pricker lamellar body is 0.1mm≤B≤4mm, height A is 0.5mm≤A≤10mm, and the size conforms Wimet cross pricker sheet head intercalation of described mounting groove is installed to be needed.
As to further improvement of the utility model, the corner that described Wimet cross pricker sheet head stretches out Wimet cross pricker lamellar body boss is the arc transition angle.
The beneficial effects of the utility model are:
Because the utility model is big outer little tight mouth groove in mounting groove is set on drill body, the intercalation of the cross pricker sheet of Wimet can be fixedly welded on the drill body, increase the contact area of Wimet and drill body, increased bonding area simultaneously, there is more scolder to be welded between matrix and the cross pricker sheet of Wimet during welding, increase its snap-in force greatly, increase its work-ing life.When the blast furnace opening had work with drilling tool, the cross pricker sheet of Wimet can not come off, and has improved the working efficiency of drill bit, has prolonged the work-ing life of drill bit.
