FIELD: process engineering.
SUBSTANCE: invention relates to hot rolling of magnesium alloy. Device arranged on roll mill feed and discharge sides is provided with winding devices to allow heating sheet S from magnesium alloy and keeping obtained temperature for reeled sheet. Said sheet thickness is sequentially reduced in multiple reversing rolling jobs. Note here that said roll mill is equipped with working and support rolls. Temperature on surface of said rolls may be increased to preset level and maintained thereat.
EFFECT: stable properties, higher yield and efficiency.
