IMPROVED METHOD FOR PRODUCING A COLD REDUCED LOW CARBON STEEL BELT AND LAMINAR MATERIAL. ',' The present invention relates to an improved method for producing a low carbon steel strip and sheet material, cold reduced; Said method comprises the steps that consist of: providing a piece of low carbon steel, totally deoxidized and vacuum degassed; hot rolling until an intermediate thickness is obtained; remove the scab by hot rolling; reduce in cold until the final thickness is achieved and recognize; This method is characterized in that the steel essentially contains,in percentage by weight: from 0.02 to 0.10 of carbon; 0.1 to 0.9 manganese; 0.02 to 0.18 for columbium, residual phosphorous, sulfur, silicon, oxygen, and nitrogen; 0.01 to 0.08 aluminum, the rest consisting essentially of iron, except for incidental impurities; the columbium is completely materially combined; the hot rolled material is cooled to a temperature not higher than 705ºc .;the hot-rolled material is cold-reduced to

1. The invention refers to an improved method for producing cold-rolled low-carbon steel strip and laminated material, which includes the following stages: providing a piece of low-carbon, completely oxidized and stripped steel; Hot rolling to intermediate thickness; hot rolling to remove ribs; cold reducing to final thickness and identification; the characteristic of this method is that steel basically contains carbon 0.02-0.10; manganese 0.1-0.9; Columbus 0.02-0.18, Residual phosphorus, sulfur,Silicon, oxygen and nitrogen; 0.01-0.08 of aluminum, which is essentially iron except impurities; coltan is completely mixed in substance; hot rolled materials are cooled at a temperature not exceeding 705 ℃;The hot rolled material is reduced in cold until its final thickness is reduced from 40% to 70%; the low temperature material is fixed at a temperature and for a period of time sufficient to recover production but not to remelt, so that the elongation exceeds 10, but with a limit. The surface elasticity is at least 63 kggmm2; or lie down at temperature and sufficient rest time to extend more than 25, and the surface elasticity limit is 31.5 kg / mm 2 to 42 kg / mm 2.
