In a four high rolling mill the diameter of backing up

A precision rolling mill, built in , with 140 mm roll diameter of the Prymetall company was used for the experiments. During the rolling of the OF-Cu bars the rolling force was measured. There were no forward and backward tensions applied on the copper bars and rolling speed was reduced to a minimum of about 0.75 m/min.rolling mill with a small work roll of 100mm diameter (R50 in the following figures) to evaluate the effect of work roll size. After the experiments of skin-pass roll-ing and simple compression, the surface roughness on the workpiece was measured, and thefer ratio ...In a four high rolling mill, the diameter of backing up rolls is _____ the diameter of working rolls. a) Equal to b) Smaller than c) Larger than d) None of these.

Mill rolls. Rolls for rolling mills

Flat Rolling • Initial thickness ho • Final thickness hf • Roll gap L• Surface speed of rolls Vr • Entry velocity of strip Vo • Final velocity of the strip Vf • Neutral point, no-slip point -point along contact length where velocity of the strip equals velocity of the roll · The typical grammage classes in our paper mill are 48 gsm, 50 gsm, 58 gsm, 60 gsm, 68 gsm, 70 gsm. The Winder station takes a paper spool that is about 6 m width as it's input and transfers is to customized paper rolls with particular diameter and width. And, the Wrapping station is used for packaging purposes where the white paper roll is ...For different rolling mills there are the following ratio of body length to diameter (L/D): Cogging mill 2,2-2,7; Section rolling mills 1,6-2,5; Plate mills 2,0-2,8; 4-hi mills a) 3-5 (for work rolls); b) 0,9-2,5 (for back up rolls). Roll neck length usually equals to roll diameter.

POWER IN ROLLING Power is applied to the rolling mill by applying Torque to the rolls and by using roll strip tension.The total rolling load is distributed over the arc of contact. However, the total rolling load can be assumed to be concentrated at point along the arc · A wire rod rolling mill, for example, gradually reduces the cross-sectional area of a starting billet (e.g., 150 mm square, 10-12 meters long) down to a finished rod (as small as 5.0 mm in diameter, 1.93 km long) at high finishing speeds (up to 120 m/sec). Tab 1 Typical parameters at rolling stages.Setting a mill includes the calculation of the openings between the various mill rolls and well as the shape and position of the trashplate. The work openings are calculated first. The work openings are the gaps between the top roll and the feed roll on the one hand and the opening between the top roll and the discharge roll on the other, when the mill is in operation.
