Abstract
The utility model relates to blast furnace equipment, in particular to a novel blast furnace lining structure which is characterized in that the furnace bottom and the furnace hearth portion of a blast furnace are provided with baking char coal block and ceramic composite furnace lining structures. The novel blast furnace lining structure comprises three layers of the baking char coal blocks sequentially laid from bottom to top, two layers of 345-millimeter plastic combined corundum composite brick lining laid vertically, a plastic combined corundum composite brick layer arranged on the contacting hot face between the furnace hearth portion and residue and iron water, a carbon brick layer arranged on the contacting cold face between the furnace hearth portion and the residue and iron water, a corundum silicon nitride combined brick lining layer arranged at a wind opening area, high alumina coating lining layers arranged on copper cooling walls of a furnace waist, a furnace bosh and the lower portion of a furnace body, a silicon nitride combined silicon carbon brick lining layer arranged in the cast iron cooling wall in the middle of the furnace body, and a vacuum soaking phosphorus clay brick lining layer arranged in the cast iron cooling wall on the upper portion of the furnace body. The novel blast furnace lining structure is novel and stable in structure, and can greatly improve service life of the whole blast furnace.
Description
Technical field
The utility model relates to blast-furnace equipment, is specifically related to a kind of novel blast furnace lining structure.
Background technology
Blast furnace is smelting equipment.Blast furnace lining is the very important structure of high furnace interior, and it is related to all many-sides such as work-ing life, the quality of production of blast furnace.Traditional blast furnace lining is limited to the effect that prolongs blast furnace campaign, can not satisfy the requirement of modern blast furnace longevity.
The utility model content
The purpose of this utility model just is to provide a kind of lining structure of blast furnace, its novel structure, stable, the work-ing life that can greatly improve blast furnace integral body.
Of the present utility model
Technical schemeFor: a kind of lining structure of blast furnace of the utility model, it is characterized in that, be provided with the furnace lining structure that roasting charcoal piece adds Ceramic Composite at Blast Furnace Bottom and cupola well position, it comprises from bottom to top three layers of roasting charcoal piece layer laying successively and the two-layer 345mm composite plasticity corundum brick air retaining wall of laid on end, and the composite plasticity corundum brick layer that is provided with of the hot side place that contacts with slag, molten iron at the cupola well position and the carbon brick layer that is provided with at the huyashi-chuuka (cold chinese-style noodles) place; Be provided with corundum silicon nitride modular tile air retaining wall in the zone, air port; Copper cooling wall at furnace bosh, bosh and restoration of lower stack is provided with High-Alumina sprayed coating air retaining wall; In the cast-iron cooling wall of shaft middle part, be provided with the air retaining wall of silicon nitride combined silicon carbide brick, in the upper shaft cast-iron cooling wall, be provided with Vaccum Permeating phosphorus clay brick air retaining wall.
The beneficial effects of the utility model are: the utility model adopts roasting charcoal piece to add the ceramic cup compound Lining at furnace bottom, cupola well position, its structure formation can satisfy the requirement of medium and small blast furnace strengthening smelting, can keep higher lining life, have high temperature resistant, thermal conductivity is good, the internal layer insulation effect is good, the advantage such as anti-slag, iron erosion action are strong.
Adopt his silicon nitride modular tile structure of bulk corundum at the air port region division; it possesses high anti-erosion, erosion resistibility, also has simultaneously certain thermal shock resistance, also with advantages such as easy dross; can effectively protect the bottom bricking, can effectively support the top bricking again.Only establishing the High-Alumina sprayed coating in bosh, furnace bosh and shaft middle and lower part outside copper cooling wall gets final product.
At the shaft middle part silicon nitride combined silicon carbide modular tile layer is set, it has preferably chemical resistance of concrete and anti-mechanical erosion ability, and thermal conductivity and shock resistance cooperate in cooling stave simultaneously, can greatly improve cooling performance, prolong blast furnace campaign; Top arranges Vaccum Permeating phosphorus undercloak, and the ability of its anti-potassium, sodium metal attack is strengthened greatly, and heat resistanceheat resistant shock resistance and erosion resistibility also improve simultaneously.
The utility model novel structure, design is unique, when improving blast furnace campaign, has also greatly improved the over-all properties of blast furnace.
