Description
Technical field
The present invention relates to high temperature hot-blast furnace and heating furnace structure, particularly relate to complete resistance to equipment structure and support checker brick furnace binding and brick-building art method.
Background technology
At present in the process furnace of metallurgy industry and petrochemical industry, generally adopt cast alloy iron fire grate, crossbeam and shore supports checker brick heat storage, cast iron support mode has strict restriction to flue-gas temperature, and namely flue-gas temperature lower than 400 DEG C, thus will have limitation.
Carbon coking analysed by petrochemical industry process furnace in fire grate cold zone comparatively serious, all need to burn carbon distribution and coking with naked light every year, fire grate, crossbeam and pillar that cast alloy iron is made want strict temperature control lower than 600 DEG C when burning carbon distribution, when temperature is more than 600 DEG C, beam strength declines 40%, occurs lower flexure strain until fracture.Burn operation normally after on air terminating, directly to pass into combustion air from vault burner and carry out burnings carbon distribution and burn, along with the carrying out of burning process, fire grate subarea temperature raises gradually, stops burning when temperature is more than 600 DEG C.Now use scaling loss method can only the coking of part decarbonizing, also need manually to remove a large amount of remaining carbon distribution coking, labor intensive and man-hour, and operating environment is severe.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, provides a kind of complete resistance to equipment structure to support checker brick furnace binding and processing method.Be applicable to high temperature hot-blast furnace and the process furnace of the industries such as metallurgical and petrochemical industry, namely meet petrochemical industry process furnace naked light below fire grate and burn the particular requirement of carbon distribution, also meet the requirement that metallurgy industry improves flue-gas temperature preheated air and coal gas simultaneously.
For achieving the above object, the present invention realizes by the following technical solutions:
Complete resistance to equipment structure supports checker brick furnace binding, comprise drop-bottom, drop-bottom upper surface is the square pillar with laying fireproof bricks, it is the heat resistance concrete of cast between square pillar, heat resistance concrete and square pillar form an entirety, and square pillar upper surface is a resistance to material arch beam of building by laying bricks or stones, an arch beam be above the secondary of the resistance to material arch beam of building by laying bricks or stones along 90 ° of vertical direction, secondary arch beam is transitional brick, is checker brick above transitional brick.
A described arch beam is lateral direction penetrating, by arch brick with build arch protection tile by laying bricks or stones form on arch brick.The radial natural wedging of arch brick, adopts boss and groove fit, to ensure the monolithic stability of arch between brick and brick.
