Description
Technical Field
The utility model belongs to the technical field of the steelmaking auxiliary assembly, a child mould is related to, specifically is a ladle is pour and is used child mould.
Background
The steel ladle is equipment for molten steel turnover in steel smelting and is divided into a shaped refractory material and an unshaped refractory material. When the unshaped castable is used for manufacturing the ladle, the castable is poured between the moulding bed and the ladle shell, and the ladle is obtained after the castable is cured and formed. The forming die is a circular truncated cone with a large upper end and a small lower end, and common ladle pouring methods in the prior art are one-step forming and one-step demoulding. And because the properties of the casting material can change along with the instability of raw materials, the difference of seasonal temperature and humidity and the uncertainty of production, the demolding mode is not easy to master the demolding time: the demolding is early, so that the castable is easy to form shear cracks and even collapse; the drawing of patterns is late, even the outer wall brush oil of giving the child mould also hardly extracts, and the drawing of patterns of forcing causes the inside damage of ladle easily, and this damage outward appearance is difficult for finding out, causes the steel accident of wearing easily in the online use, and not only the potential safety hazard is very big, still can influence the normal turnover of molten steel.
There are two conventional solutions to mold release: one method is to brush oil outside the tire mold, but the method has not ideal effect after field application; the other method is to increase the size difference between the upper part and the lower part of the forming die, but the method can reduce the gap of the whole upper part of the forming die, the construction condition of the lower part is not easy to observe, a honeycomb hole is easily formed in the casting material due to the fact that vibration is not in place, and in addition, the problems of insufficient thickness of the upper slag line of the ladle and too large safety redundancy of the lower slag line can be caused, so that the steel ladle is not paid. Therefore, it is necessary to provide a mold for pouring a steel ladle, which is convenient for demolding and can ensure the quality of the steel ladle pouring.
