Procedure for obtaining hot strip free from breakage of the coils and strip galvanized and cold resistant to aging.

摘要

METHOD FOR PRODUCING STEEL BAND NO unbowed, FREE OF COIL-BREAK WITH STRETCH IN TIME BOUND IN THE CITY OF STRETCH AND LOW STRETCH limit. TO REMOVE THE COIL-BREAK IN THE BANDS ARE HOT prevented the emergence of a STRETCH STRETCH IN THE LIMIT BY MEANS OF A SUFFICIENT OR AN ALLOY STRAIGHTENING. The steel strip according to the invention is obtained with minimal TITANIUM ADDITION AND WINDING LOW TEMPERATURES 550 to 400 C. AGGREGATE AMOUNT OF TITANIUM is chosen such that it is below the stoichiometric AMOUNT NEEDED AT LEAST ON THE ONE HAND, to bind nitrogen and the other, below that required to bind the nitrogen and carbon. In addition, it PROPOSES THE USE OF STEEL COIL-BREAK FREE AND RESISTANT TO AGING FOR BANDS CONTAINING THIS FIRE galvanized STEEL 0.02 to 0.04% titanium, WHEN IS A STEEL VACUUM, AND A 0.03 A 0.08% titanium, IF is a steel LD.
