Description
При производстве труб на трубонрокатн1)1х устаповка.х с редук11,11онным станом известными способами отмечаетс повышенный расходный коэффициент металла в результате необходимости обрезки значительной длины передних и задних конпов труб с утолщенной стенкой, по вл ющихс в процессе редуцнровани .In the manufacture of pipes for pipe-lines1) 1x installation x with a 11.11on mill, an increased expenditure ratio of the metal is noted by known methods as a result of the need to trim a considerable length of the front and rear tips of the pipes with a thickened wall that appear during the reduction process.
По предложенному способу, с целью повышени выхода годного и снижен11 расходного коэффициента металла, утолщенные концы раскатывают с последующей калибровкой труб по диаметру.According to the proposed method, in order to increase the yield of a suitable and reduced 11 expenditure ratio of the metal, the thick ends are rolled out with subsequent calibration of the pipes in diameter.
Предложенный способ заключаетс в том, что трубы после редукционного стаиа подогревают (или без подогрева) и направл ют вThe proposed method consists in the fact that the pipes after the reduction stack are heated (or without heating) and sent to
Двух- илн трехвалковый раскатный стан (типа рпллинг-машин или другого типа), где осуществл етс раскатка утолщенных концов н G случае необходимости утонен 1е стенки по всей длние трубы. Затем трубы калибруют по диаметру на калнбровочном стане.Two or three roll mills (of the type of rolling machines or of another type), where the rolling of thickened ends and G are carried out, if necessary, the 1st walls along the entire length of the pipe are thinned. Then the pipes are calibrated in diameter at the calibration mill.
