FIELD: metallurgy, namely descaling apparatuses. ^ SUBSTANCE: apparatus includes housing in which holder with nozzles is mounted; nozzle raising and rotating mechanisms joined with housing and with holder; additional mechanism for linear motion of nozzles in the form of driven shaft having at least five sections and mounted in housing in such a way that its lengthwise axis is in the same plane as lengthwise axis of holder in the form of tie rod. There is through slit opening in central section of shaft, bracket is mounted in said central section. All other sections of shaft have stem at one side and outer-thread portion with slit opening at other side; stems of said sections are mounted in slit openings of previous sections. Brackets are mounted in portions with outer thread with possibility of motion on holder along its lengthwise axis. Nozzles are mounted in brackets. Apparatus provides flexible regulation of nozzle position over surface of rolled piece at supplying liquid in real time mode. ^ EFFECT: possibility of optimal positioning nozzles of apparatus. ^ 3 dwg |
