Abstract
The utility model relates to an accessory for molten steel smelting, particularly a combined top type slag stopper which is composed of a steel core and refractory material which is wrapped on the outer side of the steel core, wherein the steel core is provided with a core rod, a chip base seat, a chip, a chip cover plate and a nut. The shape of the outer side of the steel core, which is formed by the refractory material, is a top shape. The diameter of the upper part of a top main body is larger than the diameter of a tap hole, and the diameter of the lower part of the top main body is smaller than the diameter of the tap hole. The length of the lower end of the core rod is longer than the length of the top main body. The specific gravity of the combined top type slag stopper can be adjusted by the chip and filling of the chip. The core rod has the action of guiding, and the phenomena of difficult positioning of the combined top type slag stopper caused by slag wrapping can be avoided. The utility model is suitable for the slag blocking process steps of various metal smelting furnaces.
Description
The utility model relates to the accessory that molten steel is smelted, a kind of knockdown top in shape floating plug of more specifically saying so.
Molten steel is smelted termination, and the slag that is produced floats over the molten steel surface.For stablizing the molten steel composition, improve yield of alloy, prolong the reasons such as service life of tapping hole and ladle, adopt skimming device at tapping hole usually.The most frequently used easy device is a kind of skimming ball before the utility model, also have on September 21st, 1993 " truncation turbination floating plug " by applications such as Wuan City, Hebei province 2672 Wang Li of plant produced portion brightness, application number 93224578, the inner steel core of this floating plug is an overall structure, proportion is difficult for adjusting, and is confined to 3.5～4g/cm
3Between; The steel core bottom of this floating plug is not wrapped up by anti-material, and anti-material and steel core easily peel off; Exposed steel core is very easily fusing in the molten steel of boiling; Slag blanket is in static relatively state in the tapping process in addition, and floating plug is wrapped up in and the difficult preposition that arrives can not play effective pushing off the slag effect by dense thick slag is sticking with fascinating easily of shaft in stove.
The purpose of this utility model provides a kind of energy flexible modulation proportion, and automatic accurate the putting in place of energy, and cost is low, the floating plug that pushing off the slag is effective.
The utility model has designed a kind of top in shape floating plug in order to achieve the above object, have steel core and be wrapped in its outer refractory material, it is characterized in that steel core is made up of core bar (1), chip pad (2), chip (3), chip cover plate (4) and nut (5), steel core refractory material outside (6) is constituted is shaped as top in shape, the upper end diameter of gyro body is greater than the tapping hole diameter, the lower end diameter of gyro body is less than the tapping hole diameter, the upper end of core bar can exceed gyro upper part of body plane, and the gyro body is longer than in the lower end.
The steel core core bar of the utility model floating plug design is longer than the gyro body, and core bar exceeds the part of gyro body upper end as the operation carrying handle, can not wrap up refractory material.The gyro body is longer than in the core bar lower end, after making floating plug drop in the stove, the stem portion of being longer than body is in relative darker position in the molten steel, make this floating plug arrive the tapping hole position automatically and exactly by the traction guide effect to the mobile molten steel of tapping hole around it, overcome that general floating plug is easily wrapped up by thick slag and because of not having the disadvantage that can be difficult to put in place, thereby guaranteed that effectively the utility model obtains desirable pushing off the slag effect by the targeting part that molten steel draws.The utility model core bar and chip pad adopt tight fit or pin to fix, and bar core epimere car has screw thread, so that with fixed by nut chip cover plate.
The chip of the utility model floating plug can be hollow or solid, is processed into laminated structure with general steel plate, and the selection of chip piece number is first approach of regulating floating plug proportion in the floating plug; Can arbitrarily adjust solid or hollow chip piece number according to the requirement of smelting process or different steel grade to the whole proportion of floating plug.The hollow space of the core body that hollow chip constitutes can be used trade waste, and as fillings such as sand, stone, slag, slags, the consumption of these fillers system is as second approach regulating floating plug proportion.Replace more valuable refractory material and steel with these cheap discarded objects, improved stock utilization, reduced production cost.
The refractory material of the utility model steel core outer wrapping is that refractory materials such as clay matter, high alumina matter, magnesia, magnalium matter all can.
Top in shape floating plug of the present utility model further specifies with accompanying drawing:
Fig. 1 is the utility model top in shape floating plug longitudinal profile schematic diagram, and (1) is that core bar, (2) are refractory material for chip cover plate, (5) for nut, (6) for chip, (4) for chip pad, (3) among the figure.Steel core system adopts 6 hollow chips among the figure, and the hollow space of hollow chip is not filled discarded object.Fig. 2 is the hollow chip structure vertical view of the utility model top in shape floating plug.Fig. 3 be the utility model top in shape floating plug at tapping hole pushing off the slag schematic diagram, (7) are that molten steel, (8) are converter for slag, (9) among the figure.
The utility model top in shape floating plug describes in detail with embodiment:
Embodiment 1: make a top in shape floating plug as shown in Figure 1, its preparation method is: with the smooth bar processing core bar of 300 * φ 30mm, chip pad is fixed on the core bar in friction tight mode, put 6 hollow chips, empty therein part is inserted an amount of slag, cover the chip cover plate, first-class nut places this steel core the top in shape mould to finish its refractory material outside parcel operation in the mode of cast or ramming again.Because the ad hoc structure of its lightness sensation in the upper and heaviness in the lower, the posture of standing with gyro all the time after making it drop in stove is erected in the molten steel upper strata below the slag, along with the directed traction of the molten steel that flows to tapping hole around it to core bar, and can be automatically and exactly to the tapping hole contraposition.
Embodiment 2: core bar and chip base plate are fixed with pin, the solid chip of chip, and its manufacturing process is for one of the smooth bar of embodiment 1, bore a hole on round steel, one section screw thread of car inserts pin, put chip pad and 3 solid chips, all the other technologies are identical.This top in shape floating plug working condition as shown in Figure 3.
By embodiment as can be seen, the utility model top in shape floating plug is rational in infrastructure, but have advantages such as flexible modulation proportion, the automatic accurate arrival of energy exit position, the manufacture craft of the utility model top in shape floating plug is simple, cost is low, the user uses easy to operate, applicable to various types of size converter pushing off the slag operations, also can be used in the pushing off the slag operation of other various Metal Meltings, play and stablize melting liquid composition, improve the quality of products and yield of alloy, and can prolong the service life of tapping hole or containers such as outlet of other smelting equipment liquation and ladle.
