    Simon Wright SJW Mill Consulting Ltd. Simon has spent 25 years ing in the field of hot rolling of sections, rails and sheet piles. In 2006 he was central to the Scunthorpe long rail rolling project with the development of the new Roll Pass Design for a seven stand continuous finishing mill.

  • Effect of pass schedule and groove design on the metal

    using an FEM model during the initial passes in a blooming mill, as a function of three different pass schedules, roll groove depth, collar taper angle and er radius. The simulations predicted the effective strain penetration, load, torque, fish tail billet end shapes, and metal flow behaviour at a chosen temperature, mill rpm and draft.

  • Computer-aided roll pass design for continuous billet mill

    Newton’s substitution method has been used to solve the equation. With known reduction between consecutive passes, geometrical dimension of square and passes are computed. A model has been used to calculate pass design of a finishing train of a continuous billet mill producing 60 mm square billet from 120 mm square bloom.

    The 10-pass example should be fine if you're running non-notched, postcut mild steel. If the section is notched, precut, or high-strength material, you'll need more passes to achieve desired results. Additional passes allow the material to flow through the mill with less strain.

    mill is required. Pass Design The leader sections for the multiple slit rolling pro-cess, e.g. square, rectangular or round have to be of very close tolerance. This requires: * Correct pass profile in the rolls * Correct roll gap to ensure no overfill * Correct pass alignment between top and bottom rolls * Sound roll neck bearings and positive roll

  • Design and Fabrication of Rolling Mill

    Hence there is a need for compact rolling mills with a low cost which can roll very small thickness plates. In this a rolling mill is designed to roll a maximum width of 100mm and the maximum draft value is 0.25mm per pass. Key Words: Roll force, Draft, Flow stress, Belt drive, Adjustment screw, Sleeve. 1.

  • A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING

    As regards “abnormal” rolling conditions which are more or less very “normal” for rolling mills roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined (or v versa) to reduce the risk of repeated roll
