Abstract
The invention discloses a converter spherical rounded-corner elbow furnace-lining structure. The converter spherical rounded-corner elbow furnace-lining structure comprises a converter outer housing, a magnesite brick permanent layer arranged in the converter outer housing, and a magnesia carbon brick working layer arranged in the magnesite brick permanent layer; the magnesia carbon brick working layer is composed of spherical cylindrical furnace bottom bricks, spherical rounded-corner bricks, and furnace wall bricks; the spherical cylindrical furnace bottom bricks are obtained via tight combination construction of furnace bottom wedge shaped magnesia carbon bricks, the spherical rounded-corner bricks are obtained via tight combination construction of spherical rounded-corner elbow shaped magnesia carbon bricks; the spherical rounded-corner bricks are connected with the spherical cylindrical furnace bottom bricks and the furnace wall bricks via spherical rounded-corner transition so as to form an integral whole and form the converter spherical rounded-corner elbow furnace-lining structure. Construction of the converter spherical rounded-corner elbow furnace-lining structure is tight, and converter steelmaking safety is ensured; construction of the converter spherical rounded-corner elbow furnace-lining structure is capable of prolonging service life of converter refractory materials, reducing refractory consumption of each ton of bricks of the converter refractory material, reducing consumption cost, and reducing refractory material pollution amount in the atmosphere.
Description
Technical field
The present invention relates to technical field of ferrous metallurgy, particularly relate to converter ball-type fillet ancon furnace lining structure.
Background technology
The furnace lining structure of converter is all generally that the working lining that the permanent layer selecting the burned-magnesia brick possessing good heat-blocking action to build by laying bricks or stones and the magnesia carbon brick possessing good resistance to slag chemistry erosion and the mechanical shock of opposing molten steel are built by laying bricks or stones builds formation by laying bricks or stones.The structure design of different type of furnace converter lining and masonry quality are the furnace life that quality directly affects converter, and wherein converter ball-type fillet ancon furnace lining structure stable is the key of core.At present, China's most converter bottom ancon masonry construction is all adopt at the bottom of cross masonry heater, and peripheral brick rib interlocks, and indention, is shown in Fig. 2 (7 point).Between negative layer brick and bottom brick, gap must rely on ramming mass and lock furnace bottom, and furnace wall brick pressure is built by laying bricks or stones thereon.Existing furnace bottom ancon masonry construction also has to adopt and relies on negative layer brick to block at the bottom of round kiln, there are three angle seams between at the bottom of negative layer brick and round kiln, and the gap between negative layer brick and furnace shell permanent layer needs to tamp ramming mass and completes and build by laying bricks or stones, sees Fig. 2 (8 point).Above-mentioned converter ball-type fillet ancon furnace lining structure, its ancon thermal stresses high concentration and make the abnormal melting loss of magnesia carbon brick, can cause negative section place to ooze the rubescent accident potential of steel, bleed-out and furnace shell, dangerous; The work-ing life of converter refractory materials is low, affects converter lining life, and brickwork cost is high, uneconomical.When the situation is tense in present steel industry, the requirement of Iron and Steel Enterprises in China cost declining less energy-consumption can not be met.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of structure is provided to build by laying bricks or stones tightly, ensure the converter ball-type fillet ancon furnace lining structure of converter steelmaking use safety, this masonry construction substantially increases the work-ing life of converter refractory materials, reduce the ton brick refractory consumption of refractory materials, reduce consuming cost, decrease the contamination level of resistance to material in air simultaneously.
The technical scheme adopted is:
Converter ball-type fillet ancon furnace lining structure, comprises converter shell, the magnesia brick permanent layer of building by laying bricks or stones in converter shell, the magnesia carbon brick working lining of building by laying bricks or stones in magnesia brick permanent layer.Described magnesia carbon brick working lining tightly combines sphere circle bottom brick, the shaping magnesia carbon brick of ball-type fillet ancon of building by laying bricks or stones by the shaping magnesia carbon brick of furnace bottom wedge shape and tightly combines the spherical fillet brick of building by laying bricks or stones and furnace wall brick forms, described spherical fillet brick connects sphere circle bottom brick and furnace wall brick by spherical round-corner transition, and form an entirety, form converter ball-type fillet ancon furnace lining structure.
Structure of the present invention is built by laying bricks or stones tightly, ensures converter steelmaking use safety; This structure builds the work-ing life substantially increasing converter refractory materials by laying bricks or stones, reduces the ton brick refractory consumption of refractory materials, reduces consuming cost, decrease the contamination level of resistance to material in air simultaneously.

Embodiment
Converter ball-type fillet ancon furnace lining structure, comprises converter shell 1, the magnesia brick permanent layer 2 of building by laying bricks or stones in converter shell, the magnesia carbon brick working lining 3 of building by laying bricks or stones in magnesia brick permanent layer.Magnesia brick permanent layer 2 wherein furnace bottom magnesium carbon ramming mass ramming is smooth, and keep circular arc degree, described magnesia carbon brick working lining 3 tightly combines sphere circle bottom brick 4, the shaping magnesia carbon brick of ball-type fillet ancon of building by laying bricks or stones by the shaping magnesia carbon brick of furnace bottom wedge shape and tightly combines the spherical fillet brick 5 of building by laying bricks or stones and furnace wall brick 6 forms, described spherical fillet brick 5 connects sphere circle bottom brick 4 and furnace wall brick 6 by spherical round-corner transition, and form an entirety, form converter ball-type fillet ancon furnace lining structure.This structure is built by laying bricks or stones tightly, there are not three angle seams; Ancon thermal stresses obtains dispersion and decomposes, and only occur less fluctuation at ancon and furnace bottom, ancon and junction, furnace wall, ancon center, then in wave trough position, eliminates thermal stresses peak value; Smooth spherical ancon coordinates with at the bottom of sphere circular furnace, minimum to the resistance of molten steel stream, and ancon magnesia carbon brick melting loss is slow.
