The preformed part is characterized in that the preformed part is constructed in the permanent layer of the wall of a steel ladle and adopts a circle cylinder structure composed of a plurality of arc-shaped preformed units, the sectional area of the upper annular cross section of the preformed part is greater than that of the lower annular cross section, the arc-shaped preformed units are connected through materials with the same texture in a padding manner. According to the utility model, the preformed part has the following advantages: the number of the gap of constructing steel ladle slag line can be reduced, and the height, thickness and quantity of the preformed part can be adjusted according to the size of the steel ladle and the aggressive strength of molten steel and steel slag; the arc-shaped preformed units are jointed to use, which is suitable for steel ladles with different sizes, and in addition, the module cost is lowered, the rapid replacement of the preformed part used for the refined steel ladle slag line can be realized, and the whole service life of the refined steel ladle can be prolonged.
Description
Technical field
The utility model relates to a kind of prefabricated component for refining ladle slag line.
Background technology
Along with continuous progress and the maturation of ladle refining technology, in order to meet the requirement of smelting process, the material of refined steel ladles refractory material is selected and building method has also obtained development and optimization.At present, domestic and international most of refining ladle adopts carbonaceous material as working lining brick, at the bottom of generally adopting magnesia carbon brick, magnesia-alumina-carbon brick etc. to build Bao Bi and bag by laying bricks or stones.Permanent ladle layer generally adopts lightening casting material, plays function of heat insulation.For refining ladle, slag line position is a weakest link, and ladle slag line position is owing to being subject to for a long time the erosion of ladle refining slag, the violent scour effect of high-temperature molten steel in refining process simultaneously, and the service condition of slag line refractory brick is very harsh.Conventionally adopting high-purity fused magnesite, high grade graphite is raw material, and compound additive, by high-pressure molding, be prepared into the magnesia carbon brick of arc and wedge shape, adopt flat block or the horizontal brick work refining ladle of laid on end mode slag line, between adjacent refractory brick, with pug, connect and fill.The advantage of this building method is to produce Eroded when ladle slag line is local, can carry out part and mend by replacing a damaged part, extends ladle slag line service life.The maximum inferior position of this building method is that the gap between slag line refractory brick is more, is easily subject to washing away and corroding of molten steel and slag, causes the frequent repairing of ladle slag line, if large area Eroded appears in ladle slag line position, will directly affect the ladle integral life-span.
