The surface of a whole-roll flatness roll is in long-term contact with the steel strip, leading to slipping and wear placing higher demands on performance surface. This study establishes finite element model for moving induction quenching phase transformation hardness numerical by generating multi-field simulations predictions during quenching. First, thermal–physical properties material, MC3, are calculated using JMatPro V13.0. dynamic domain mesh techniques applied COMSOL Multiphysics...
Seamless flatness rollers are the core equipment for cold-rolled strip detection. The change in wear resistance of roller surface-strengthened layer has important guiding significance prediction surface life. experimental results five rounds friction and testing show that volume–wear rate original is only 1.85 × 10−6 mm3 (N·M)−1. After first grinding, decreased was approximately 2.76 second morphology, samples each round showed little difference. average last three test 3.56 (N·M)−1...
Contact-type flatness meters are the key detection equipment in production of high-end cold-rolled thin strips. The surface performance a meter roller is very important to improve its service life and ensure quality strip products. To wear resistance prolong seamless roller, it was subjected strengthening treatment by laser cladding an Fe-based wear-resistant alloy. strengthened quenching determined tests. results show that cladding-strengthened layer forms solid metallurgical bond with...
Under certain conditions, the whole roll flatness meter outputs a bimodal waveform signal, which is clearly different from conventional unimodal signal. Since detection relies on extraction of crest values and two waveforms do not have same linearity, presence channels will give rise to errors in calculated distribution. To develop an effective method, it necessary accurately analyze evolution waveforms. In this paper, finite element method used calculate load sensor, stress distribution...
