Abstract
The utility model relates to a slag stopper for a converter. The utility model is a hemisphere (3), wherein, a plane part arranged on the hemisphere (3) is the upper part of the hemisphere (3), and a spherical surface part is the lower part of the hemisphere (3). The upper part of the hemisphere (3) is provided with reinforced bars (2), the lower part of the hemisphere (3) is provided with a guide rod (4), and an up and down directional groove (1) is arranged on the hemisphere (3). The utility model has the advantages that because the gravity center of a floating plug is moved downwards, the floating plug can not be floated in molten steel; because of the guiding function of the guide rod, the floating plug can be easily and accurately fallen to a steel tapping hole of a rotary furnace, and the operation is convenient.
Description
Technical field
The utility model relates to the articles for use that are used for steel-making converter, particularly steel-making converter when falling the molten steel, is used for keeping off the floating plug that slag is used.
Technical background
In converter steelmaking process, steel-making converter when falling the molten steel, need floating plug is dropped in the stove, floating plug can slowly sink in the molten steel in stove, and the tap hole place that falls converter clogs tap hole, molten steel in the stove goes out by the concentrated flow on the floating plug, slag in the stove in stove, is entered next process, influence steel-making quality to avoid slag to flow out with molten steel by the floating plug retaining.
Existing steel-making converter floating plug is a spheroid, and spheroid has groove; There is following defective in it: 1, because the center of gravity of spheroid is placed in the middle, floating plug is easily floating in molten steel; 2, the very difficult tap hole place that falls converter exactly of floating plug.When above-mentioned situation occurring, often need drop into a plurality of floating plugs and just can clog tap hole, make troubles to work, improved steel-making cost.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of converter floating plug is provided, and it can be not floating in molten steel, can be easy to, fall exactly the tap hole place of converter.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: it is a hemisphere, and the planar section on the hemisphere is hemispheroidal top, and land portions is hemispheroidal bottom; Hemispheroidal top is provided with reinforcing bar, and hemispheroidal bottom is provided with tail rod; Have the groove of above-below direction on the hemisphere.
When the utility model floating plug uses, use the reinforcing bar on clamp clamps hemisphere top earlier, the tail rod of hemisphere bottom is downward, send into steel-making converter, tail rod is aimed at tap hole, unclamps anchor clamps, floating plug can be fallen the tap hole place of converter exactly, clog tap hole, molten steel goes out by the concentrated flow on the hemisphere, and slag is kept off in stove by hemisphere.
The hemispheroidal bottom of the utility model floating plug is provided with tail rod, have the following advantages for: 1, because the center of gravity of floating plug moves down, floating plug can be not floating in molten steel; 2, owing to the guide effect of tail rod, floating plug can be fallen the tap hole place of converter easily, exactly, and is easy to operate.Therefore, the utility model floating plug can overcome the problem that the defective because of existing spheroid floating plug causes.

Specific embodiments
The utility model embodiment 1 as shown in Figure 1, 2, 3, it is a hemisphere 3, hemisphere 3 is the semiellipse spheroid; Planar section on the hemisphere 3 is the top of hemisphere 3, and land portions is the bottom of hemisphere 3; The top of hemisphere 3 is provided with reinforcing bar 2, and reinforcing bar 2 is a Deformed Steel Bars; The bottom of hemisphere 3 is provided with tail rod 4; Have the groove 1 of 3 above-below directions on the hemisphere 3.
The utility model embodiment 2 as shown in Figure 4 has the groove 1 of 2 above-below directions on its hemisphere 3.
The utility model embodiment 3 shown in Fig. 5,6 has the groove 1 of 4 above-below directions on its hemisphere 3.The center of its hemisphere 3 is provided with the hole of passing for reinforcing bar 2; Be cast with the high alumina corundum on reinforcing bar 2 bottoms and form tail rod 4; Reinforcing bar 2 passes the hole at the center of hemisphere 3, fastens reinforcing bar 2 by square iron piece 5 on the plane of hemisphere 3, and the pour mass of tail rod 4 and square iron piece 5 are fixed into an integral body with hemisphere 3, tail rod 4, reinforcing bar 2.
By experiment, the utility model embodiment 1 (3 groove), embodiment 2 (2 groove), embodiment 3 (4 groove) are compared, the result is: the utility model embodiment 1 (3 groove) and embodiment 3 (4 groove) have that stream steel speed is fast, the stream steel time is short, retaining slag effect obviously, molten steel advantage such as can go out to the greatest extent, therefore, the utility model embodiment 1 (3 groove) and embodiment 3 (4 groove) are optimum implementation.
