  • GENERAL ASPECTS OF ROLL COOLING FOR HOT COLD

    HSS rolls often installed in the earlier stands of hot strip mills provide improved wear resistance along with a better surface roughing resistance. However HSS are rolls more sensitive during operation and require a higher grade of attention with regard to roll cooling than High-Cr rolls. HSS rolls need an adequate mill operating environment

  • Patents Assigned to Tippins Machinery Company Inc

    Abstract A process of rolling steel in a reversing mill by passing the steel back and forth through the mill for a selected number of passes to achieve the desired thickness and on at least two early passes each in a different direction tapering the ends of the steel during taper passes by adjusting the roll gap the roll gap adjustment ( LTA.H) being a function (F( LTA.F b.m)) of the

  • FAG Rolling Bearings in Rolling Mills

    The work rolls in four-high strip mills and the rolls in two-high fine-section and wire mills are predominantly fitted with angular contact ball bearings as axial bearings (Figure 10). The chock arranged on the drive end is not axially located in the roll stand but is guided on the roll neck by the axial bearing. Since the guidance forces are

  • CorrosionpediaWhat is a Reversing Mill Definition

    Rolling mills can use two three or four rolls. In two-high reversing rolling mills the rolled metal may pass back and forth through the rolls several times. The disadvantage of reversing mills is that the rolls must be stopped reversed and then brought back up to rolling speed between each pass. The three-high mill was invented to resolve

  • Roughing Millan overview ScienceDirect Topics

    The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll force and roll torque were available so the friction coefficient could be evaluated in addition to the flow stress for each pass. The values were close to 0.3 so it was decided to use this for

  • SteelHot strip Britannica

    SteelSteelHot strip The rolling of hot strip begins with a slab which is inspected and if necessary surface cleaned either manually or by scarfing machines with oxyacetylene torches. The slabs are then pushed or walked on their broadside through gas-fired furnaces that have a hearth dimension of about 13 metres by 30 metres. In a pusher-type furnace the slabs slide on water-cooled
