Abstract
The utility model relates to a fitting used for tapping from a tapping hole of a steel-making converter, in particular to a thin-shell slag stopping cap. The thin-shell slag stopping cap comprises a frustum cone-shaped hollow cylinder which is formed in one step from a thin steel plate; and is characterized in that a round small through hole is arranged at the front end of the cylinder, and serrated fins are uniformly arranged at the rear part of the cylinder. During usage, the slag stopping cap is plugged into the tapping hole through a front pin until the slag stopping cap is firmly plugged. The thin-shell slag stopping cap has novel structure and uniform stress, and is easy to be fabricated. The rear part of the thin-shell slag stopping cap has high tension and strong tenacity, and is tightly and firmly combined with the tapping hole and is not easy to fall off, so that the thin-shell slag stopping cap is safe and reliable in use, improves slap stopping success rate, and is favorable for purifying molten steel. The thin-shell slag stopping cap is convenient in storage and transportation.
Description
Technical field
The utility model belongs to steel-making converter, relates in particular to converter taphole tapping accessory.
Background technology
Before the converter steelmaking tapping slag retaining cap is filled in the tap hole, slag is gone out and is entered in the ladle when avoiding converter to topple over.The iron-clad slag retaining cap of current employing is conical.Before the tapping earlier with the pushing off the slag cap stopper in converter taphole, topple over converter then gradually, when slag floats on tap hole above water the time, molten steel is gone out tap hole, enters in the ladle together with slag retaining cap.Its defective is, the steel plate quality is hard, and smooth surface cooperates badly with tap hole, in conjunction with imprecision, come off easily during converter inclining, causes the pushing off the slag failure.The disclosed utility model patent of Patent Office of the People's Republic of China " slag retaining cap " (ZL88211711.4) is made of cap head, core body and the software skin that refractory materials is made, its defective is: complex structure, the trilaminate material difference, substep is made, and mould is many, and work efficiency is low, interlayer is low in conjunction with fastness, inconvenience stores and transportation, and slag retaining cap falls into ladle, also pollutes molten steel.
Summary of the invention
In order to overcome the defective that prior art exists, the purpose of this utility model provides a kind of shell slag retaining cap, and is simple in structure, and processing is safe and reliable easily.
The shell slag retaining cap is with the one-time formed truncated cone hollow cylinder of steel sheet, be characterized in that barrel front end establishes circular small through hole, the cylindrical shell rear portion evenly is provided with lanced fin, and during the connector slag retaining cap, fin is subjected to the extruding of tap hole, in particularly filling in, during the rear portion, the fin stress deformation produces outside tension force, toughness is strong, and slag retaining cap combines fastness with tap hole to be strengthened greatly, can hold the pressure of slag, prop up that slag retaining cap is unlikely to come off.
The utility model further improves, and described lanced fin is trapezoidal, and the base is straight.Processing easily, stressed even during use.
This slag retaining cap is inserted in the tap hole by front end during use, until the plug jail be as the criterion, slag retaining cap under the extruding of tap hole, stress deformation, slag retaining cap combines closely with tap hole.
Advantage is: the isosceles lanced fin is established at the cylindrical shell rear portion, and novel structure is made easily, and is stressed even; Slag retaining cap rear portion tension force is big, and toughness is strong, and slag retaining cap combines close and firm with tap hole, and difficult drop-off is safe and reliable, improves the pushing off the slag success ratio, helps pure molten steel; Storage, convenient transportation.
Description of drawings
The utility model is described in further detail for the contrast accompanying drawing below.
Fig. 1 is a shell slag retaining cap structural representation.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is embodiment 2 structural representations.
Embodiment
By Fig. 1, Fig. 2 as can be seen, the shell slag retaining cap is a truncated cone hollow cylinder 1, and the front portion is provided with aperture 8mm small through hole 2, around the rear portion lanced fin 3 is set evenly and is " trapezoidal ", and fin base 4 is straight, long 10mm.
As seen from Figure 3, the slag retaining cap superstructure is identical with embodiment 1, around the rear portion lanced fin 3 is set evenly, is down " trilateral ".
Claims (3)
1. the shell slag retaining cap is the one-time formed truncated cone hollow cylinder of steel sheet (1), it is characterized in that cylindrical shell (1) front end establishes circular small through hole (2), and the cylindrical shell rear portion evenly is provided with lanced fin (3).
2. shell slag retaining cap according to claim 1 is characterized in that described lanced fin (3) is " trapezoidal ".
