Abstract
The utility model provides a slag stopper for converter steel tapping, which belongs to the field of steel smelting technology. The utility model solves the problem of separating the slag and molten steel when the converter taps steel. The hit ratio of blocking a steel outlet is high, which ensures the purity of the molten steel. The utility model is manufactured and integrated by fire-resistant material. A convex is added and arranged on the hemispheric surface of a stopper plug, which greatly simplifies the manufacturing process and reduces the cost.
Description
Technical field
The utility model belongs to the technical field of smelting of steel.
Technical background
According to the knowledge of the applicant, the converter tapping later stage, for preventing that the buoyant slag enters in the ladle on the molten steel, pollute molten steel, must use floating plug to block slag liquid, to guarantee the pure of molten steel.All there is certain problem in the general slag-blocking ball that uses aspect hit rate and the pushing off the slag effect now.Applicant's existing patent (ZL00261785.4) solves these problems effectively, all obtains good achievement on hit rate and pushing off the slag effect.But on manufacturing process, still dislike complicated slightly, cost still can reduce.
Summary of the invention
The purpose of this utility model will provide a kind of floating plug exactly, and it can keep the excellent properties of former floating plug aspect hit rate, pushing off the slag effect, can simplify manufacture craft again, further reduces cost.
The purpose of this utility model is to realize like this, a kind of converter tapping floating plug, it is made up of hemispheric chock plug and the tail rod that passes the plug at its center and stretch out chock plug, it is characterized in that: on the hemisphere face of the semisphere chock plug of being made by the refractory materials that mixes iron and steel particle and iron and steel fiber several cross sections being arranged is the protruding stupefied of semicircle; Protruding stupefied from top, extend to the bottom of hemisphere.
Because chock plug all is to make with the refractory materials that mixes iron and steel particle and iron and steel fiber, as long as adopt suitable prescription and mould, just can once shaped, needn't add the cast iron epidermis in its outside again.But refractory materials can not melt in molten steel, must keep the speed of molten steel trickling again at this moment, for this reason, just adds on the hemisphere face of chock plug that several are protruding stupefied, allows molten steel trickle so that enough gaps to be arranged between assurance chock plug main body and the tap hole, and the slag that dams simultaneously.Protruding stupefied quantity and cross-sectional sizes will be according to the amount of capacity of converter and reasonable selection.
Like this, the utility model can obtain good pushing off the slag effect, blocks shooting straight of tap hole, and molten steel is separated with slag, when improving the molten steel recovery rate, has guaranteed the pure of molten steel, has simplified manufacturing process again greatly, has reduced cost.
Description of drawings
Fig. 1 is an organigram of the present utility model.
Fig. 2 and Fig. 3 are the organigram of chock plug.Wherein Fig. 3 is the A-A sectional view of Fig. 2.
Wherein: 1. plug 2. chock plugs 3. tail rods 4. are protruding stupefied
Embodiment
As shown in Figure 1, main part of the present utility model is hemispheric chock plug (2), and plug (1) passes from its center, stretches out chock plug (2) land portions at plug (1) and is with the tail rod (3) that refractory materials is made.
Fig. 2 and chock plug (2) shown in Figure 3 are all made by refractory materials, and uniform several protruding stupefied (4) are arranged on the hemisphere face, and protruding stupefied (4) extend to the bottom of hemisphere from top.
In the converter tapping later stage, when swimming in slag on the molten steel and might flow into ladle by tap hole, the plug (1) of floating plug by the mechanical manipulator clamping, insert in the converter taphole, under the guiding of tail rod (3), chock plug (2) is blocked tap hole, molten steel can only drop down from the gap that its protruding stupefied (4) and tap hole inwall form, flow to end, and the bigger slag liquid of toughness just is blocked, stays in the stove.The utility model is blocked shooting straight of tap hole, and pushing off the slag is respond well, obtains bigger molten steel recovery rate when guaranteeing the molten steel cleaning.
Claims (1)
1. converter tapping floating plug, it is made up of hemispheric chock plug (2) and the tail rod (3) that passes the plug (1) at its center and stretch out chock plug, it is characterized in that: on the hemisphere face of the semisphere chock plug of being made by the refractory materials that mixes iron and steel particle and iron and steel fiber (2) several cross sections being arranged is protruding stupefied (4) of semicircle; Protruding stupefied (4) extend to the bottom of hemisphere from top.
