Description

Сталь разливали в слитки весом 8,8 т. Слитки прокатывали по стандартной технологии , включающей в себ  гор чую прокатку , травление, двукратную холодную прокатку до толщины 0,15 мм с промежуточной термообработкой.Steel was cast into ingots with a weight of 8.8 tons. The ingots were rolled according to standard technology, including hot rolling, pickling, double cold rolling to a thickness of 0.15 mm with intermediate heat treatment.

Свойства холоднокатаной ленты из предлагаемой стали полиостью соответствуют требовани м, предъ вл емым к ленте дл  изготовлени  теневых масок, и значительно превыщает свойства ленты из известной стали.The properties of the cold-rolled tape of the proposed steel completely meet the requirements of the tape for the manufacture of shadow masks, and significantly exceeds the properties of the tape made of known steel.

Технико-экономический эффект от внедрени  низкоуглеродистой стали при производстве из нее холоднокатаной ленты составит 200 тыс. рублей в год.The technical and economic effect of the introduction of low carbon steel in the production of cold-rolled tape from it will be 200 thousand rubles a year.
