Embodiment Construction

[0027] The ladle composite masonry technology includes an insulation layer 2, a permanent working layer 3, and a consumable working layer 4, which are sequentially built from the ladle steel shell 1 inward. The described consumption working layer 4 is changed from a traditional one-layer working layer to an inner layer working layer 6 and an outer layer working layer 5 by composite masonry. The inner layer brick of the inner layer working layer 6 and the outer layer working layer 5 When the outer layer of bricks is compositely built, the horizontal and vertical joints should be staggered. Its composite masonry technology includes the following steps:

[0028] Step 1. Preparation of masonry materials. Before masonry, prepare the materials required for masonry, such as joint materials, knotting materials, insulation boards, nozzle seat bricks, breathable seat bricks, bottom-covering and wall-covering consumption working layer bricks , Bottom-covering and wall-covering permanent...

Abstract

Disclosed is a steel ladle compounding building technology. An insulation layer, a permanent working layer and a consumption working layer are sequentially built from a steel ladle steel shell from the inner side. The consumption working layer is formed by compounding and building an inner working layer and an outer working layer instead of being simply formed by one working layer. When inner bricks of the inner working layer and outer bricks of the outer working layer are compounded and built, transverse and vertical joints are staggered. The steel ladle compounding building technology includes the following steps that building materials are prepared; the walls and the bottom of a steel ladle are coated with insulation boards; a refractory material is used for forming the permanent layer on the insulation boards; the bottom of the ladle is leveled; the bricks of the steel ladle are built; the permanent working layer and the working layers are bonded through high-temperature refractory clay; and the edges of the ladle are encrusted and baked after the bricks are built. By the adoption of the steel ladle compounding building technology, the risks of steel seepage and steel leakage are avoided, production safety is improved, the service life of the steel ladle is prolonged, the broken brick detaching number is greatly reduced, resource waste is avoided, energy is saved, emission is reduced, labor intensity is lowered, and the building work efficiency is improved.

Description

technical field [0001] The invention relates to steel-protected masonry technology in the field of metallurgy, in particular to ladle composite masonry technology. Background technique [0002] The steel ladle is an essential container for containing molten steel and refining outside the furnace. The refractory materials used for the ladle need to withstand harsh conditions such as high tapping temperature, long residence time of molten steel, boiling of molten steel, stirring and scouring of molten steel, slag erosion, and thermal shock spalling caused by temperature changes. environmental impact. The service life of refractory materials for ladles is an important factor affecting the efficiency and quality of steelmaking. Therefore, reducing the damage of refractory materials and improving their service life are the research focus of refractory materials for ladles. Damage to refractory materials for ladles mainly includes penetration and erosion of slag, thermal shock ca...
