冷轧带钢生产技术手册
冷轧带钢生产技术手册第一章：冷轧带钢生产概述1．什么叫冷轧，冷轧带钢有哪些优点金属在再结晶温度以下进行轧制变形叫做冷轧，一般指带钢不经加热而在室温直接进行轧制加工。
冷轧后的带钢可能烫手，但还是叫冷轧。
冷轧生产可提供大量高精确度和性能优良的钢板和带材，其最主要的特点是加工温度低，同热轧生产相比，它有以下优点：(1)冷轧带钢产品尺寸精确，厚度均匀，带钢厚度差一般不超过O.01-0.03mm或更小，完全可以符合高精度公差的要求。
(2)可获得热轧无法生产的极薄带材(最薄可达0.001mm以下)。
(3)冷轧产品表面质量优越，不存在热轧带钢常常出现的麻点、压入氧化铁皮等缺陷，并且可根据用户的要求，生产出不同表面粗糙度的带钢(光泽面或麻糙面等)，以利于下道工序的加工。
(4)冷轧带钢具有很好的力学性能和工艺性能(如较高的强度、较低的屈服极限、良好的深冲性能等)。
(5)可实现高速轧制和全连续轧制，具有很高的生产率。
2．冷轧生产方法有哪几种冷轧板带钢生产方法分为单片轧制和成卷轧制两种方法。
(1)单片轧制。
单片轧制最早采用二辊式轧机，目前多用四辊式冷轧机。
四辊冷轧机按其轧辊运转方向可分为可逆式和不可逆式。
采用不可逆式四辊轧机进行单片生产时，轧制操作是由人工逐张将钢板喂入轧机，全垛钢板轧完一道次后，用吊车将板垛吊送到轧机前，进行下一道次的轧制，如此循环进行，直到轧成规定的成品尺寸时为止。
采用可逆式轧机时，则轧制操作有两种，一种是每一张钢板在轧机上往返轧制，直到轧制成最终的成品尺寸，然后再进行第二张钢板的轧制。
这种操作方法虽然压下调整操作频繁，但产品表面不易划伤，故实际生产中应用较多，特别是轧制单重和尺寸较大的钢板，均采用此法。
另一种是每张钢板逐张送入轧机，待全垛钢板轧完一道次后，再逐张返回轧制第二道次。
此种操作方法使轧制产品尺寸较均一，而且省去了轧辊反转和压下的调整时间，从而冷轧机产量较高，但板面之间有时可能造成划伤。

A pragmatic approach to your needs allows us to develop high performance products. Our objectives: extend the service life of your equipment, make maintenance intervals longer, avoid unscheduled downtimes and as a result reduce production costs. This allows you to reduce the environmental footprint of your equipment.Raw materialsSintering Coking plantFrom raw materials to sintering equipmentContinuous casting equipmentConverterBlast furnaceCoalLimestoneCokeSlab Bloom BilletRolling millContinuous hot or cold rolling of flat products or long productsPressed steel plate Electromagnetic steel platePipe Welded pipeThick pressed steel plateProfiles Special profiles Bar and wireSealing to extend service life• Efficient solution against pollution.• Pressed steel or machined brass cage.• Seals suitable for temperatures up to 200°C.• Cylindrical or taper bore.Very high resistance to vibration,impact and load• M achined brass cage.• Special reduced bore tolerance.• Special reduced outer diameter tolerance.• Special clearance tolerance (C4+).• Optional surface treatment against fretting corrosion on theinner ringNTN-SNR offers a wide range of open or sealed spherical roller bearings (EE).EF800 series RAW MATERIALSPreparing raw materials for manufacturing steel requires a number of conveying and screening equipment.

To do so, there should be a transition from liquid phase to solid phase. Continuous casting rollers are therefore subject to high stress (load, temperature, etc.). NTN-SNR’s specific products for fixed, free and intermediate bearing units help to meet these severe requirements.FREE SIDE BEARING OF GUIDE ROLLFIXED SIDEROLLING MILLSteel rolling requires high precision products and complete reliability. Designed for heavy loads, high speeds and/or requiring reinforced sealing, NTN-SNR products provide a tailed solution for each type of rolling mill (cold or hot). A specific processing of the steel along with the heat treatment of these bearings ensures optimal service life.Sealed four-row tapered roller bearings “Large size, long service life EA bearings”• T hree times longer life than standard case hardened steel bearings (continuous hot rolling mill).• S ealed bearing does not require greasing during operation and effectively reduces the environmental impact (no grease leakage).Four-row cylindrical roller bearings• EA bearings for longer life (optional).• C an be equipped with pin type cage to maximise rated load capacity and further extend life.Double-row tapered roller bearings•E quipped with pin type cage to maximise rated load capacity and further extend life.• S teep contact angle to maximise performance underaxial loads.Tapered roller thrust bearings• G eneral bearing shape maximises load capacity.• Inner ring surface is spherical to fit pressure screw shape.WORK ROLLBACKup ROLLPRESSURE SCREWBACKup ROLL THRuST BEARiNgSealed four-row tapered roller bearings for rolling mill• High load capacity.• Extremely compact seal.• Specific grease as standard.`Specially designed for applications:• With high loads.• In highly polluted environments.Anti-corrosion treatment (Rust guard™)• N TN-SNR has developed Rust guard™ coating, which is a special phosphate coating that does not affect the roughness of the base material during the coating formation process, in order to avoid the premature failure of bearings and down times due to rust.• Moreover, Rust guard™ also has good anti-seizure properties thanks to its good grease retention capacity.• Rust guard™ coating can be used in addition to version EA.ConventionalbearingsRust Guard™ SeriesbearingsReplacement cycle (month)102030The use of proven sealed or Rust guard™ surface-treated bearings extends the service life of the bearings and of the rolling mills.Large-sized four-row tapered roller bearings “pin type cages”• Equipped with pin type cages to increase the number of rollers, load capacity is maximised.• EA bearings ensure longer life.Split cylindrical roller bearings for pilger mill • B y its design, the crankshaft allows only split bearings to be mounted.• The bearing has a highly resistant cage and a load capacity to withstand operating stress.Metal industrial constant velocity joints for rolling millIndustrial constant velocity joint with mechanical metal seal for demanding environments such as high temperature, water and scale.industrial constant velocity joint (large-sized) for reversible rolling mills (Skin pass)• Sealed with rubber boots with superior performance, does not require re-lubrication.• The constant velocity of the joint eliminates shattering marks on rolled surface. (Sizes #250 – 725).Split cylindrical roller bearings foROLLING MILLAs essential addition to the range, NTN-SNR has developed high load capacity bearings as well as specific split bearings. The range of NTN industrial constant velocity joints allows the transmission of rotation movement without vibration to your equipment.Backing roll bearings for Sendzimir cold strip mill• Because it is directly used for backup roll, the bearing is stronger and has a thicker outer ring.• Mutual difference of assembly thickness for bearings mounted on same shaft is controlled to be extremely small.• This bearing is manufactured for high load capacity and high precision.Roller tableindustrial constant velocity joint (BC coupling type, long shaft series)• Sealed with rubber boots with superior sealing performance, does not require re-lubrication,• Uses a corrosion-resistant steel for shafts.Sealed type backing roll bearings for Sendzimir cold strip mill• S eals allow the use of special lubricating oil to maximise service life.• Enables recovery of waste oil; does not affect rolled materials.•Enables use of low viscosity rolling oil.COLD ROLLING SPECIALNTN-SNR has developed bearings suitable for “Sendzimir” cold rolling mills.
