Embodiment Construction

[0021] The ladle wall of the present invention adopts an integral casting lining, which is composed of an insulating layer, an integral casting permanent layer, an integral casting working layer and the like. The insulation layer can be insulated with refractory fiberboard, asbestos board and insulation coating. First, the insulation board can be fixed on the ladle shell by bonding or anchoring. Secondly, the permanent layer is integrally cast on the inner side of the thermal insulation layer, and then the working layer is integrally cast after curing, demolding and baking of the permanent layer. The castable can simultaneously make up for the cracks in the permanent layer during the baking process and increase The safety of ladle in use.

[0022] The permanent layer and the working layer are respectively cast with the same castable for the working layer of the ladle for integral casting. Therefore, the two can finally achieve the effect of being one.

[0023] When the working lay...

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 casting process for a lining in a steel ladle. Background technique [0002] In the prior art, the inner lining structure of the ladle is composed of two parts: the outer permanent layer and the inner working layer. Chinese patent application CN97215132 discloses a "ladle integral casting lining", which is between the permanent layer and the casting layer. The refractory brick layer is built in between, and the cast layer and the refractory brick layer must be removed after the ladle built by this method is 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 ladle at home and abroad mostly adopts integral casting structure. The integral casting structure consists of an external permanent layer and an internal working layer. It has the characteristics of high labor productivity, low ove...
