Solve Problem, only assume a cluster mill with working rolls of radius = 50 mm. Compare the results with the previous two problems, and note the important effect of roll radius on force, torque and power. A slab that is 9 in wide and 24 in long is to be reduced in a single pass in a twohigh rolling mill to a thickness ...
Roll Pass design for steel The cross sectional area is reduced in each pass and the form and size of the stock gradually approach the desired profile. Here the thickness of the metal being rolled is reduced in each pass by decreasing the distance between the rolls. The subsequent passes in rolling section steel are called roughing passes.
Feb 13, 2017 · CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.
I have tried to give an idea that what pass designing actually is. How sophistied is this apparently crude looking art of steel rolling.
Also known in the art is a method of Isection rolling in a completely continuous mill consisting only of horizontalroll stands (refer to Bakhtinov B. P., Shternov M. M. "Roll Pass Design" published in 1953 by Metallurgizdat, pages 586592) or of horizontalroll and combination (horizontal and verticalroll) stands in a roughing train and ...

The hotstrip mill squeezes slabs, which can range in thickness from two to ten inches, depending on the type of continuous caster, between horizontal rolls with a progressively smaller space between them (while vertical rolls govern the width) to produce a coil of flatrolled steel about a quarterinch in thickness and a quarter mile in length.
Feb 25, 2016 · Rolls and roll pass design. ... In a continuous mill, speed matching the stand to achieve a constant mass flow through the mill assures a low cobble rate and fewer defects. High tension can ...
steel steel Continuous casting: About 55 percent of the world's liquid steel production is solidified in continuous casting processes, the most widely used of which feeds liquid steel continuously into a short, watercooled vertical copper mold and, at the same time, continuously withdraws the frozen shell, including the liquid steel it contains.
Nov 21, 2015 · Cluster mill or Sendzimir mill stand – In this rolling mill stand, each of the work rolls is supported by two backing rolls. Cluster mill and Sendzimir mill are used for rolling thin strips of high strength materials and foils [ mm thick]. The work roll in these mills can be as small as 6 mm diameter – made of tungsten carbide.
Oct 11, 2001 · Production process in these plants in continuous from coiled steel by means of roll forming . When roll forming several process limitations for instance value of stesses in sheets edges when the sheet is bent crosswise, diameter to wall ratio have impact on selection of stand number, roll pass design, installation of roller guide between the ...

A new technique is developed to analyze the roll pass design of a section rolling mill. Metal forming nonuniformity and efficiency coefficients, which determine the degree of working of a metal microstructure in rolling of section bars, are used as performance criteria. The system of roll passes intended for the production of a round bar 28 mm in diameter is used as an example to analyze ...
The steering roll assembly shown in the drawings comprises a pair of laterally spaced and parallel steering rolls 2 over which strip S, moving through a continuous strip mill or processing line, is looped and travels in the direction indied by the arrows, the strip moving to and from the rolls 2 respectively along passlines indied ...
