Ladle neck bush pouring technique

Abstract

The invention discloses a ladle lining casting technology, which comprises the following steps: 1) detaching ladle slag brick, cleaning slag on the ladle wall working layer, reacting layer and deteriorated layer, 2) placing the mould to locate, 3) casting between mould and ladle wall with the same material as working layer, 4) stripping after health preserving, 5) toasting.

Description

technical field

[0001] The invention relates to a ladle inner liner pouring process. Background technique

[0002] In the existing technology, the inner lining structure of the ladle is composed of two parts: the outer permanent layer and the inner working layer. The refractory brick layer is built in between, and the pouring layer and the refractory brick layer must be removed after the ladle built by this method has been used for the rated number of times, which increases the labor intensity of the workers, and the construction period is long and the cost is high. In recent years, the lining of large and medium-sized ladles at home and abroad mostly adopts an integral casting structure. The integral casting structure is composed of an external permanent layer and an internal working layer. It has the characteristics of high labor productivity, low comprehensive cost, and little pollution to molten steel. . However, from the aspects of baking, use and repair of the ladle,...
