PROCESS FOR THE PRODUCTION OF THIN SHEET METALS INTENDED FOR DEEP DRAWING

摘要

Steel with improved deep-drawing properties, a method for producing thin sheets to be deep-drawn and obtained thin sheets.;Steels with improved deep-drawing properties are characterized by containing, by weight, carbon in an amount of 0.015% or less, manganese in an amount of 0.15 to 0.25%, sulfur in an amount of 0.012% or less and aluminum in an amount of 0.04% or less. do.;This steel is especially the work of the next stage:;In the conversion furnace, production of steel having the above component ratio;;-Fully hot rolled in the austenite region;;Winding at a temperature of -650 ° C. or higher;;It is used in the manufacture of thin steel sheets to be drawn-drawn by a method consisting of continuous annealing at a temperature of not more than 700 ° C after incineration rolling.
