Product Name: Hot Rolled Coils Stock: Not Stock Technique: Hot Rolled Certification: ISO, RoHS, IBR Standard: ASTM, JIS, GB, AISI, DIN, BS Trademark: CNBM Transport Package: Standard Export Packaging Specification: Thickness: 1-12mm Origin: China Product Description Product Description:One,introductionHot rolled coilisused for continuous castingslab or slabas raw material,after reheating furnace heating,scalesentered the roughing millinthe high pressure water,roughing cut is expected by the head,tail,and then enter the finishing mill,the implementation of the computer controlled rolling,finally after rolling through the laminar cooling(computer controlled coolingrate)and coilingmachine coiling,become straight hair volume.Hair straightener roll head,tail often forms a tongue shape andfishtail,thickness,width ofpoor accuracy,edge has wavy,folding,tower and other defects.The volume weight heavier,steel coil diameter is 760mm.(generalpipeindustrylikeuse.)2two,characteristicsBecause there is noafter annealing treatment,thehardness is veryhigh(HRB greater than 90),mechanical processingperformance is poor,only a simplebending processhasless than90 degreedirectional(directionperpendicular to therolled).3,usethreeHot rolled productswith high strength and good toughness,easy processing and good formingcan beexcellent performanceofwelding,which is widely used inships,cars,bridges,buildings,machinery,boiler,pressure vesselmanufacturingindustry.The scope of application:(1)after annealingprocessing into thecommon cold;(2)processinggalvanizedgalvanizedunitbefore theannealing treatment;(3)the basicdo not need to process thepanel.4four,classificationCarbon steel plate,carbon plate,low alloy plate,ship plate,bridge plate,boiler plate,container plateetc..Rolling hardvolumes:under normal temperature,the hot pickling volumes of continuous rolling.Hot rolled steel stripproducts includesteel(roll)andtheshearof steel plate.Andsteel(coils)can be divided intostraightandfinishesvolume(the volume,smoothrollingandslittingroll).
