Embodiment Construction

[0008] The method for repairing the inner lining of the ladle bricklaying work of the present invention comprises the following steps:

[0009] 1. When the lining of the brick ladle reaches 70 times of replacement or needs to be replaced, the lining will not be removed, but the residual steel and residue on the working lining of the ladle should be cleaned up.

[0010] 2. Prepare the tire mold according to the method of integrally pouring the inner liner.

[0011] 3. Put the tire mold into the ladle, inject the aluminum-magnesium spinel castable between the tire mold and the brick lining, and tamp it.

[0012] 4. After pouring, let it dry naturally for 24-30 hours to demould.

[0013] 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 material construction, and particularly relates to a method for lining the inner lining of ladle brickwork. Background technique [0002] The inner lining of the ladle is mainly composed of a permanent layer and a working layer. When the ladle age reaches a certain number of times and the working layer is melted and lost to 1 / 3 of the original thickness, the working lining needs to be removed and a new work will be built. lining. Due to the high cost, high cost and labor intensity of the working lining refractory materials used in the masonry ladle, improving the repairing method of the working lining has become a common problem faced by steel-making enterprises. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a method for repairing the inner lining of a ladle bricklaying work, which can increase the ladle age, reduce the consumption of refractory mat...
