FIELD: machine building.
SUBSTANCE: invention relates to rolling of long products (bi). System comprises at least one braking module (6) comprising a plurality of electromagnets (60) arranged in series along braking line (1b), each of which is configured to excite magnetic field (B), and comprises open magnetic core (61) and winding (62) around said magnetic core (61), wherein open magnetic core (61) comprises a gap formed by two opposite poles, between which said magnetic field (B) flows, and gap of each open magnetic core (61) is able to place and pass with contactless sliding through it each long product (bi) coming out of rolling mill (100), such that braking magnetic force (Fd) is applied to said long product (bi) by said electromagnets (60), when said long product (bi) slides through said gap without contact, wherein said braking magnetic force (Fd) is opposite to direction of movement of said long product (bi) coming out of said rolling mill (100). Preservation of shape and functional characteristics of rods, as well as reduction of process space is provided due to, that electromagnets (60) are staggered along said braking line (1b) in accordance with first row and second row so as to form alternating arrangement with each other along said braking line (1b), wherein first and second row electromagnets (60) are offset relative to each other in a direction transverse to said braking line (1b), such that all of the gaps formed by the two opposite poles of each magnetic core (61) are aligned to allow long-length product (bi) to pass through them free of contact.
EFFECT: disclosed are a braking system for slowing down long products, exempli gratia rods coming out of a rolling mill, intended for making said long products, and a method of controlling said long products.
