Avertissement: Heavy Rolling Mill Vibration Harms Equipment & Creates Defects – Field-Ready Fixes Many steel mills face one tough trouble on site. Their rolling mill bodies shake heavily during operation. Loud strange noises come out at startup. Most operators take this lightly. They think vibration is normal as long as
Au cours des dernières années, multiple technical improvements including rolling mill process optimization and roll device performance upgrading have effectively boosted roll hardness, thermal crack resistance and impact resistance. These measures cut roll consumption and significantly prolong roll service life. This paper mainly analyzes typical roll failures in hot narrow strip production:
Le laminage à chaud et le laminage à froid sont deux procédés de formage essentiels pour les tôles et profilés en acier., qui modifient considérablement la microstructure interne et les propriétés mécaniques de l’acier. Quelles sont leurs différences essentielles? La production d'acier repose principalement sur le laminage à chaud. Cold rolling is only adopted to manufacture precise-sized products including small-sized section steel and
Question 1: Problems & Countermeasures of Grooveless Rolling (1) Instability of rolled pieces Without constraint from groove side walls in grooveless rolling, rolled stock is prone to square distortion and offset. Larger reduction leads to worse stability and interruptions to rolling. Solutions: Install double-row rolling guides at mill entry; equip
