Ladle with seepage-proofing insulation layer and masonry method of ladle

Abstract

The invention discloses a ladle with a seepage-proofing insulation layer and a masonry method of the ladle. A ladle bottom seepage-proofing insulation layer is arranged between a ladle bottom and a working layer of the ladle bottom, a ladle wall seepage-proofing insulation layer is arranged between ladle wall and a working layer of the ladle wall. The ladle bottom seepage-proofing insulation layer comprises a glass fiber blanket which is laid on the ladle bottom, a mixture mixed by fire-resistant knot tieing material and water of which mass percentage is 1:0.15 to 1:0.20 is poured between the glass fiber blanket and the working layer of the ladle bottom. The ladle seepage-proofing insulation layer comprises an asbestos plate which is pasted on the inner side of the ladle wall, a glass wool cloth is pasted on the working layer opposite to the ladle wall, and the mixture mixed by fire-resistant casting material and water of which the mass percentage is 1:0.30 to 1:0.35 is poured between the asbestos plate and the glass wool cloth. The seepage-proofing insulation layer provided by the invention is formed through entirely tieing the mixtures of the fire-resistant casting material and water or a mixture of the fire-resistant knot tieing material and water through vibration in batches. The used material is ordinary, knot tieing method is simple, the seepage-proofing insulation layer is sturdy and durable, ladle leakage accidents can be completely eradicated, and production security is improved.

Description

Technical field [0001] The invention relates to a molten iron ladle and a masonry method thereof, in particular to a molten iron ladle with an anti-seepage and thermal insulation layer and a masonry method thereof. Background technique [0002] The ladle in the prior art is composed of a ladle bottom, a ladle wall, and a ladle mouth. The ladle bottom and ladle wall are provided with a working layer made of refractory bricks on the inner side. The ladle bottom and the ladle wall form a cladding shell, and the working layer is also It is commonly referred to as the inner lining. In the process of packaging and transporting molten iron, the inner lining is subject to high temperature, thermal shock, mechanical abrasion and chemical erosion of slag iron. In recent years, the temperature of molten iron has increased significantly compared with before, up to 1500 degrees, which further aggravated the erosion of the lining. Furthermore, in the process of molten iron pretreatment, the ...

Problems solved by technology

What's more serious is that due to the strong fluidity of molten iron, in this case, the ladle is prone to serious leakage and iron leakage accidents.
