A method is proposed for determining the geometric parameters of the deforming region in rotary-rolling mills. In this method, the change in size of the deforming region due to roller rotation and the supply is described by relatively simple formulas. Results of calculations by the proposed and familiar methods are compared for piercing and rolling mills. The …
A possible solution is to build a special mill for rock drill steel rolling, but in most cases rock drills form a very small part of the production volume in the mill.

In the hot continuous rolling process, the main factor affecting the actual thickness of strip is the rolling force. The precision of rolling force calculation is the key to realize accurate on-line control. However, because of the complexity and nonlinearity of the rolling process, as well as many influencing factors, the theoretical analysis of the traditional rolling …
The results indicate that the formulas for calculating vertical force and rolling force presented in this paper are more accurate than the Linear Cutting model and the CSM model. Although the calculation results of the lateral rock breaking force conforms to the variation law of lateral rock breaking force with the penetration and cutter ...
The working roll diameter is 500 mm. Determine the rolling load on the rolling stand if the co-efficient of friction is 0.07. Also determine the rolling torque. Solution: Example 2: A billet of area of section 150 mm x 150 mm is rolled to 120 height in a rolling mill with 600 mm roll diameter at a temperature of 1100 °C at 3m/sec.

Force parameters of rolling solid and hollow parts were also determined. The aim of the FEM analysis was to determine initial design assumptions and parameters for the development of the skew rolling mill. Later on in the paper, a design solution of a CNC skew rolling mill for rolling parts based on their envelope profile is proposed.
