Embodiment Construction

[0010] The method for covering and repairing the inner lining of ladle bricklaying work of the present invention comprises the following steps:

[0011] 1. When the lining of the brick ladle reaches 70 times or needs to be replaced, the lining is not removed, but the residual steel and residue on the working lining of the ladle are cleaned.

[0012] 2. Prepare the tire mold according to the method of pouring the inner lining as a whole.

[0013] 3. Put the tire mold into the ladle, inject the aluminum-magnesium spinel castable between the tire mold and the brick lining, and compact it.

[0014] 4. Let it dry naturally for 24-30 hours after pouring.

[0015] 5. Bake on low heat for 24 hours, then bake on medium heat for 16 hours, and then bake on high heat for 8 hours.

Abstract

The invention discloses a case repairing method of steel brick laying working lining, which comprises the following steps: 1) cleaning residual steel and slag on the lining, 2) assembling fetal mould, 3) casting material between fetal mould and bricking lining, tamping, 4) drying naturally for 24-30h, stripping, 5) toasting at little flare for 24h and middle flare for 16h and large flare for 8h.

Description

technical field [0001] The invention belongs to the field of metallurgical refractory construction, and in particular relates to a method for repairing the brick lining of a ladle. Background technique [0002] The ladle lining is mainly composed of a permanent layer and a working layer. When the age of the ladle reaches a certain number of times of use and the working layer is melted and lost to 1 / 3 of its original thickness, the working lining needs to be removed and a new one should be rebuilt. lining. Due to the high cost and high cost of working lining refractory materials used in masonry ladles, and the high labor intensity of workers, improving the repair method of working lining has become a common problem faced by steelmaking enterprises. Contents of the invention [0003] The purpose of the present invention is to provide a method for repairing the inner lining of ladle brickwork, which can increase the service life of the ladle, reduce the consumption of refrac...
