Experimental Research on Durability in Exploitation of Rolling Mill Rolls
Having in view the statistical data calculated for 10 years, the total consumption of rolling mill rolls represents 0 785...0 8 kg/tone of rolled steel. Nationwide, the 5 million tones steel being rolled every year represents a consumption of 4000 tones rolls, worth 6 million euro/year, which imposes large research with an important economic and scientific impact [1-6] It is noticeable that app...
متن کاملRing Rolling FE Analysis in The Presence of the Guide Rolls
A new method (thermal spokes) is proposed to simulate the guide rolls in FE analysis of the ring rolling process. So far this method is the only one, capable of calculating guide rolls reaction contact forces related to the stiffness of their adjustment mechanism. The method is simple to use, does not introduce further nonlinearities and could be used in any kind of FE formulations. The method ...

متن کاملProbability Analysys for Rolling Rolls Calculation as per Probabilistic Method
Two calculation methods are mainly implemented during the construction as well as modeling of the rolling rolls. These are: deterministic (classical) and probabilistic – calculation based on reliability. When using deterministic method, starting point considers that the workloads as well as material specifications are invariable values. However, in reality, rolling rolls are burdened with varia...
متن کاملNumerical Simulation of the Effect of Elastic Deformation of work rolls on the rolling force and Comparison with the Results obtained by the Slab Method during the reciprocating cold rolling
Cold rolling process of a major transformation in the form of sheet metal and a wide range of steel products are produced in this way. Elastic deformation during cold rolling working rollers and the inevitable increase in the rolling force. In this study, the effect of elastic deformation during cold rolling mill rollers working on the reciprocating back and forth in tandem with the presence of...
