mechanical engineering: Types of rolling mills. Rolling mills may be classified according to the number and arrangement of the rolls (a): Two high rolling mills (b): Three high rolling mills, It has a roll stand with four parallel rolls one above the other The top and the bottom rolls rotate in opposite direction as do the two middle rolls The two middle are smaller in size than the,
Most primary rolling is done in either a two high reversing mill or a three-high continuous rolling mill. Final products from hot rolling include plates, strips and a wide variety of bars and sections. Plates and strips are normally rolled between two plain cylindrical rolls, or on four-high mills. a. …
ADVERTISEMENTS: For obtaining extremely narrow thickness tolerances and good strip flatness, six-high roll mill is preferred because of the facility of positioning the intermediate rolls and also the facility for positive/negative bending of both the work and intermediate rolls. For automation of such a mill, the electrical and hydraulic screw down equipment has to be […]

One or more spray bars having a plurality of spray nozzles for cooling a rolling mill roll are provided with an apparatus to cause at least one spray bar to undergo a translational, rotational, and/or pivotal movement sufficient to change the spray-angle and/or spray-distance affected by nozzles thereon to thereby control the cooling rate effected by the nozzles so moved.
The Q & T Process. The quenching & tempering process as per Thermex ® makes use of the heat energy of the rolled bar after the finishing stand of the rolling mill. Normally, this energy is wasted as the rolled bars at 950-1000 0 C are allowed to cool to ambient temperature on the cooling bed.
