Rolling (metalworking) Wikipedia
Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material After the grains deform during processing, they recrystallize, which maintains an equiaxed microstructure and prevents the metal from work hardening The starting material is usually large pieces of metal, like semifinished casting products, such as slabs, blooms, and billetsCOUPLED PICKLING LINE TANDEM COLD MILL Highcapacity production of highquality products For a wide range of products, the required strip thickness, flatness and surface quality can be achieved more economically by linking the pickling and coldrolling processesCoupled Pickling Line Tandem Cold MillMETHOD FOR COLD ROLLED TUBES USING A PELOTE ROLLING MILL AND DEVICE FOR CARRYING OUT THE METHOD EPA1 (en) * : : Vallourec: Method of coldrolling tubes by way of a pilper mill and device for carrying out the method USA (en) * : : Sumitomo Metal Industries, LtdUSA Pilger rolling mills Google Patentswith short mandrels, Pilger mills, and threehigh threadrolling mills Coldrolling mills for steel and nonferrous metals include (1) sheet mills for piece work rolling, (2) wideband sheet mills for reel rolling, (3) striprolling mills for rolling strips 1 mm to 4 mm thick and 20 to 600 mm wide, the strips then being coiled or reeled, (4) foilrolling mills for rolling bands less than 01 Rolling mill Article about rolling mill by The Free Coyote Steel Co 2030 Cross Street Eugene, Oregon 97402 USA No 1 Handbook of STEEL SIZES WEIGHTS For Industry Phone: 5414612060 Tollfree: 18005530240Handbook of STEEL SIZES WEIGHTS
