CAD Simulation of Roll Pass Design of Angle Steel

By analyzing the teachnological process and roll pass design program of angle steel, a software system applied to simulte angle steel roll pass design by computer is established, which can directly simulate and design the roll pass of angle steel and the present roll pass figure can be generat by using AutoCAD R14 under this system. This software can simulate roll pass to check light so that

(PDF) Roll Pass design for hot flat rolling of plain

A good roll pass design must ensure a profile with a smooth surface and correct dimensions within the limits specified in the concerned standard .It must ensure minimum specific consumption of energy, power and roll and give deformation to the rolling stock in such a way and at stages so as to have minimum internal stresses in the finished product.

2014-1-8  Contact Angle The enclosed angle between a line from the point where the stock first contacts the roll to the center of the roll and the vertical centerline of the rolls is the angle of contact(sometimes referred to as the bite angle). For a given roll diameter and gap setting, the contact angle will increase as the incoming stock height increases until a point is reached where the rolls


ROLL PASS SEQUENCES The process under consideration is rolling of a 20 mm diameter round bar from 55 mm diameter input stock. In terms of materials, this roll pass design must

Computer-aided roll pass design for continuous billet

A mathematical model has been developed for computing the geometrical dimensions of square-diamond square pass sequence for a continuous billet mill. The model is based on derivation of shape and size factor from the geometry of the pass taking into account pass filling, pass rounding etc. Using these factors and a basic equation of spread for flat rolling, a governing equation incorporating

Computer Aided Roll Design for Open Sections for Roll

2013-12-19  keeping the design rules in an integrated expert system, a CAD code named COARD (Computer Aided Roll Design) was developed for roll design of open section in roll forming process. the COARD code can compute the strip width (L) for the cross section, number of forming passes (n) and bend angle increment (??) between each pass and other.

Prediction of roll separating force in a roll pass design

2014-5-17  Roll force is considered as an important segment in the process of design dog bone and slit pass grooves. Actual readings from the industrial rolling field were fed to the model to verify the precision of calculation by model. During the rolling process, the steel section changes from pass to pass, i.e. round-oval-round. The contact angle

Fin Pass Rolls JMC Rollmasters

These factors are controlled by the angle and condition of the fin blade as the metal passes through each pass. A good roll design considers the dynamics of girth growth vs reduction and the subsequent edge distortion when determining the correct roll contour and fin angles. Reduction and Girth Control:

Roll Tooling Design Fin Designs

2021-5-6  The angle is altered by approximately 5 degrees in just the last pass. However, if the angle on the last pass is only 1 or 2 degrees, it would be beneficial to just remove the angle completely, and make it flat. A flat oval design is most often used in the last pass and only in certain cases.

The basics of roll form tooling design

2003-3-27  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. Design the Layout and Roll

Analysis of TON pass problem in a roll-pitch optics

2011-7-31  With the mentioned requirement, roll-pitch seeker with its advantages smart size and large gimbal angle is studied widely and deeply. The pitch angle of roll-pitch is up to ±90° while its roll angle up to n × 360°. But there are also some disadvantages for the roll-pitch seeker, the most troublesome one is the TON pass problem.

Roll Forming Machine Design How Does Roll

Roll forming machine work continues by special roll design on amount of stand. All stand drives together and will roll material with the same speed. roll forming technology came for easier and faster processing on sheet metal to precise demanded profile. each stand of tooling will make small forming on material and pass it to the next stand. as
