Abstract

The utility model discloses an embedded swing nozzle prefabricated part, which comprises a prefabricated part main body, wherein the shape of the end surface of the prefabricated part main body is of an arc shape corresponding to a swing nozzle. One end surface of the prefabricated part main body protrudes outwards from the bottom of the arc to form a step. The height of the step is one second of the bottom height of the prefabricated part main body. Two grooves which penetrate through the two side end surfaces are arranged on the bottom surface of the prefabricated part main body. The shape of the grooves is triangular. In the utility model, the swing nozzle prefabricated part which is high-temperature sintered is embedded into the swing nozzle part, then castables is poured at the periphery thereof to make the swing nozzle to form a composite structure, while the step at one end surface of the prefabricated part main body, which is formed at the bottom of the arc, is poured and covered by the castables, so the prefabricated part and the swing nozzle are integrated into a whole body. The utility model has the advantages of energy conservation, durability and convenient maintenance.
本实用新型公开了一种嵌入式摆动嘴口预制件,包括预制件本体,所述预制件本体端面形状为与摆动嘴口对应的圆弧状。所述预制件本体的一端端面在圆弧底部向外突出形成一个台阶。所述台阶的高度为预制件本体底面高度的二分之一。所述预制件本体底面上设有两条贯穿两侧端面的凹槽。所述凹槽的形状为三角形。本实用新型将高温烧结好的摆动嘴口预制件嵌入到摆动嘴口部位,然后在其周围浇注上浇注料使摆动流嘴形成复合结构,而预制件本体的一端端面在圆弧底部的台阶由浇注料浇注覆盖,使预制件与摆动嘴口的结合为一个整体。具有节能、耐用和维修方便的优点。
