IRON BASED METAL PLATE AND METHOD OF ITS MANUFACTURING |
摘要 |
FIELD: metallurgy.SUBSTANCE: cast flat billet containing C below 0.02 wt % is subjected to hot rolling at temperature equal to A3 temperature or above. Then rolling in ?-area is performed at temperature 300°C or above and below A3 temperature with manufacturing of the base metal plate with structure {100} in part of the surface layer. Then by heat treatment under specified conditions the metal plate is manufactured, in which for intensities ratio of the appropriate stresses {001}<4 7 0>, {116}<6 12 1> and {223}<6 9 2> in the plate plane as per X-ray diffractogram designated as A, B and C, respectively the condition Z=(A+0.97B)/0.98C is met, where Z is at least 2.0 and 200 maximum.EFFECT: energy losses decreasing upon decreasing of the magnetic cores dimension.15 cl, 5 dwg, 11 tbl, 4 ex |
