Description
Technical field
The invention belongs to technical field of refractory materials, be specifically related to a kind of State of Blast Furnace at the bottom of cupola well with brick fuel and preparation method thereof.
Background technology
Along with the fast development of Iron And Steel Industry and the continuous progress of ironmaking technology, blast furnace develops to maximization, longevityization direction.Restriction blast furnace long-lived key link generally believes it is cupola well furnace bottom position; This is because behind the modernized large blast furnace strengthening smelting; Molten iron circulation causes huge erosion damage effect to the cupola well furnace bottom; Molten iron very easily is penetrated in the bricking along brickwork joint and hole, bricking is caused serious erosion and repairs unusual difficulty, thereby had a strong impact on blast furnace campaign.Therefore as far as the cupola well furnace bottom, it is particularly important that the brick fuel quality seems, life-span that we can say brick fuel has determined the life-span of blast furnace.
" a kind of high corrosion resistant porous baked carbon brick that is used for blast furnace lining " (ZL00116085.0) with " the micropore self-baked charcoal brick that is used for ironmaking blast furnace lining " (ZL00116084.2) patented technology; In traditional brick fuel, introduce metallic titanium powder; Not only raw materials used metallic titanium powder costs an arm and a leg; Cause the production cost of brick fuel to increase, and the resistance to fouling of brick fuel improve very little; " a kind of ironmaking blast furnace lining carbon brick and preparation method thereof " be patented technology (ZL200410061026.3), in brick fuel, introduces titanium dioxide powder, has improved the solidity to corrosion of brick fuel to a certain extent, but can not satisfy the requirement of modern large blast furnace; " furnace lining is with ultramicropore brick fuel and method of manufacture thereof " be patented technology (ZL200410026087.6), though＜1 μ m pore volume arrives more than 80%, and its molten iron corrosion rate is higher, is 20%; " blast furnace carbon brick of a kind of molten iron erosion-resisting and preparation method thereof " be patented technology (CN200910063095.0); The molten iron corrosion rate of prepared brick fuel is about 15%; " a kind of Carboneous fire-resistant material for furnace brick lining and preparation method thereof " be patented technology (CN200910060989.4); Substitute the main raw material of electro-forge hard coal with amorphous graphite, only improved the micropore rate and the erosion-resisting characteristics (its anti-corrosion index is greater than 9%) of brick fuel to a certain extent as the preparation brick fuel; Other has employing that brick fuel impregnated in to contain in the zirconic solution (Materials and Corrosion, 2005,56:475-480); Though improved its resistance to fouling to a certain extent; But its complicated process of preparation, production cost is higher, is unfavorable for the reduction of blast furnace ironmaking cost.
