Steel qhov rooj hluav taws yog qhov cuam tshuam tiv taus, nrog lub zog muaj zog uas tuaj yeem tiv taus kev sib tsoo ntev yam tsis muaj kev tiv thaiv hluav taws, thiab tuaj yeem tiv taus qhov cuam tshuam ntawm hluav taws kub. Lub thermal deformation tus nqi ntawm steel hluav taws qhov rooj yog qhov tsawg, thiab qhov khoov curvature ntawm lub deformation tom qab cua sov yog tsawg.
