Description
Technical field
The utility model relates to large-scale smelting stove field, and a kind of high-strength climbing prolongs formula double plate shell hasp furnace lining structure specifically.
Background technology
Along with the raising of environmental consciousness and the contradiction of shortage of resources, and the energy-conserving and environment-protective of smelting building material industry, compression manufacturing cost requirement, these industries are generally to intensive, development of maximizing, wherein as the smelting kiln of one of production line nucleus equipment, also more and more maximize, need to bear more complicated hot smeltingization reaction strongly.After stove shape is determined, stove furnace lining carries all high temperature smelting functions and heat energy guiding function, is the core component of stove.Furnace lining self also consumes heat energy in thermal process process, and the smelting kiln body of heater of maximization, does not have spare unit in production line, blowing out must repair, lose huge once damage.Therefore, large-scale stove, in the urgent need to more stablizing solid stove furnace lining, can adapt to long period health and run.
Chinese large-sized smelting stove is mostly together introduce from the external production line introduced successively nearly two more than ten years, and furnace lining configuration is in company with introducing.The furnace lining introduced is brick furnace lining, what be close to outer steel shell is light-weight brick heat-insulation layer furnace lining, nexine is that the working lining of heavy laying fireproof bricks meets fiery furnace lining, two floor kiln lining gross thickness, between 550mm to 750mm, meets fiery working lining bricking thickness through body of heater furnace roof between 340mm to 500mm.A major comonomer furnace lining weight can reach 1000 to thousands of tons of.Therefore, the skeleton structure and the foundation of civil work that support large-scale body of heater are very large, and this body of heater furnace lining becomes the main flow furnace lining of present Large Furnace kiln lining.
But this furnace lining has a lot of shortcoming.For example: the mechanical structure of this furnace lining is separation property dual-gripper system, namely the continuous support system of outer steel shell metal and internal refractory brick working lining pile up formula support system, both mechanical support system is because belong to the outer steel shell of metallic bond material and the refractory brick of covalent bonded material, increase with temperature and present different expansions and deviate from and show different Strength Changes and pattern of body form change, between each layer furnace lining, the special disease of different calorific intensitys and expansion characteristics is had between furnace lining and outer steel shell, along with the raising of temperature, cause layering between furnace lining, furnace lining is separated with outer steel shell, two mechanical structures are caused to be separated, furnace lining stability declines, the body of heater shape of stove and volume are expanded again be restricted.And for example, high level refractory raw material is day by day rare, and in order to maintain the stable of furnace lining self, existing furnace lining adopts the structure of same furnace lining and thickness to be configured regardless of body of heater position and corresponding smelting condition, is the waste to high level refractory raw material resource; And for example: a large amount of building mortar layer of brick furnace lining meeting fire defines bricking meeting fire and can produce " sticky heat " phenomenon during thermal field on bricking work furnace lining surface in contacting, the intensity difference that brick body and puzzle joint are formed causes interior thermal field heat to pass through puzzle joint back and forth and produces hot harmonic wave at interior thermal field edge and hot spiral-flow produces interference to heating center, causes thermal source to waste; And for example: very thick furnace lining makes body of heater heavy, cause converter body support skeleton and foundation of civil work to strengthen, construction investment increases.
