Изобретение относитс  к области черной металлургии, в частности к отливке полых заготовок на установках непрерывной разливки металлов.The invention relates to the field of ferrous metallurgy, in particular to the casting of hollow billets in continuous casting of metals.

Известен способ непрерывной отливки полых заготовок на установке непрерывной разливки металла путем заливки металла з кольцевой зазор между кристаллизатором и дорном с подачей охлаждени  не только в дорн, но и на слиток.There is a known method for continuous casting hollow billets in a continuous metal casting plant by pouring metal into an annular gap between the mold and the mandrel with cooling applied not only to the mandrel, but also to the ingot.

Недостатком произвольного охлаждени  внутренней поверхности полого слитка  вл етс  образование дефектов: наплывов и проплавлений при малом расходе воды, трещин - при чрезмерно большом..The disadvantage of an arbitrary cooling of the inner surface of a hollow ingot is the formation of defects: sagging and penetration with low water consumption, cracks - with an excessively large ..

С целью получени  качественной внутренней поверхности слитка и стабильности процесса разливки по предложенному способу воду дл  вторичного охлаждени  внутренией поверхности слитка подают на нее из форсунок или спреера с коэффициентом расхода воды в пределах I-3 и определ ют удельный расход в из услови , что он должен быть пр мо пропорциональным этому коэффициенту расхода воды и обратно пропорционален корню квадратному из значени  времени затвердевани  на участке вторичного охлаждени  полостп, прот женностью от конца дорна до уровн  полного затвердевани  слитка в следующем соотношении;In order to obtain a high-quality inner surface of the ingot and stability of the casting process according to the proposed method, water for the secondary cooling of the inner surface of the ingot is fed to it from nozzles or sprayer with a coefficient of water consumption within I-3 and the specific flow rate is determined from directly proportional to this coefficient of water flow and inversely proportional to the square root of the value of the solidification time in the section of the secondary cooling of the polost, extending from the end of the mandrel to the level vn full hardening of the ingot in the following ratio;

Тггде: В - удельный расход воды, - коэффициент расхода воды; т - врем  затвердевани  слитка.  Тггде: B - specific water consumption, - water consumption coefficient; t is the ingot solidification time.

Предмет изобретени Subject invention

Способ непрерывной отливки полых заготовок путем заливки металла в кольцевой зазор между кристаллизатором и дорном с подачей воды дл  охлаждени  не только в дорн, но и на слиток, отличающийс  тем, что, с целью получени  качественной внутренней поверхности слитка, воду подают на длине от конца дорна до уровн  полного затвердевани  слитка, а расход воды пр мо пропорционален коэффициенту расхода воды и обратно пропорционален корню квадратному из времени затвердевани  слитка на участок охлаждени , причем коэффициент расхода воды равен 1-3.A method of continuously casting hollow blanks by pouring metal into the annular gap between the mold and the mandrel with water supply for cooling not only into the mandrel, but also onto the ingot, characterized in that, in order to obtain a high-quality inner surface of the ingot to the level of complete solidification of the ingot, and the water consumption is directly proportional to the coefficient of water consumption and inversely proportional to the square root of the ingot solidification time per cooling section, with the coefficient of water consumption being 1-3.
