摘要

steel fe - al for nieorientowane sheet goes, containing by weight: max. 0,06% coal, max. 0,4% silicon, 0,05 - 1,0% manganese, max. 0025% phosphorus, max.0035% sulphur iron and inevitable impurities is the rest of it, contains 0.5 - 10,0% aluminium.in one variety way to produce nieorientowanych sheets of is, with steel zawierajacej weight: max. 0,06% coal, max. 0,4% silicon, 0,05 - 1,0% manganese, max.0025% phosphorus, max.0035% sulphur, 0.5 - 10,0% aluminium, iron and inevitable impurities, the rest of the leak out kesisko flat, which walcuje on hot on grubosc 1,4 - 3.5 mm,and then after wytrawieniu walcuje on cold blache about zalozonej grubosci. then blache subjected first wyzarzaniu odweglajacemu processes przelotowych at max.900u00b0c in moist atmosphere nitrogen - hydrogen, and then wyzarzaniu koncowemu at 850 - 100u00b0c in hydrogen atmosphere.
