The Applied Design And Manufacture On The Shell Of Blast Furnace In Xin Steel No.8to Off-site Overhaul

Firstly,This subject introduced the ironmaking process,discusses the structure andtype of the blast furnace of NO.8for Xin Steel, analyze the advantages of the shellfactory of blast furnace about processed holes, point that the development trend of theprocessed holes made in the shell of the blast furnace.In this subject, the shell of blast furnace of NO.8for Xin Steel Off-site overhaulfrom steel material selection, thickness design calculations, furnace shell banding,segmented design, conduct preliminary design bevel technical development. Gives twocalculation methods for thickness, formulas and draw reasonable design parameters.This research primary focus of the design is the shell of Blast furnace processedholes. From the expanded view of the principle, processed holes was baked shellcalculation principles, methods, hole diameter, hole expanded graph vertical, horizontalposition for detailed analysis and calculation, specifically for bolt holes, water holesand copper plumbing stave hole location on a straight section of the cone segmentsexpand computing and computer lofting pass propose to start drawing process.This research another focus is the design of shell of Blast furnace manufactureprocess. Material from the Computer Numerical Control (CNC), the beveling,processed holes, round, pre-installation processes one by one analysis, the focusspecified process design parameters. The ability of rounding for the device to calculatethe translation and roller adjustment amount calculated decline. Solutions technologyquestion for the actual production, processing and guiding role in the successful completion of the furnace shell hole quantity, plate thickness specifications, hole sizespecifications, hole shape specifications," more than four " engineering manufacture.The following main conclusion can be drawn based on the design:1The Xin steel NO.8of blast furnace overhaul，the processed holes technologycan significantly shorten the processing period to facilitate the blast site construction;2CNC flame cutting and computer-aided design techniques used combine，effectively traditional hand radically improved materials, lofting process scheme, withremarkable results;3The shell of blast furnace processed holes technology to meet the high-temperature blast, blast pressure, high fever fatigue usage conditions required;4Compared to the traditional processed holes, The shell of blast furnaceprocessed holes, technology can improve the efficiency of cooling equipment installedmore than doubled, to shorten the duration of20days.The shell of blast furnace processed holes is successful application of technologyto enhance the company’s blast furnace equipment market competitiveness in theindustry in a more advanced level.
