Description

Изобретение относитс к прокатному производству , конкретно к получению бесшовных труб из циркониевых сплавов.The invention relates to rolling production, specifically to the production of seamless pipes from zirconium alloys.
Известен способ гор чей прошивки, включающий деформацию нагретой заготовки валками на оправке 1.There is a method of hot firmware, including the deformation of the heated billet rolls on the mandrel 1.
Однако в процессе прошивки не достигаетс требуема гомогенность структуры издели по продольному и поперечному сечени м.However, during the firmware process, the required homogeneity of the product structure along the longitudinal and cross sections is not achieved.
Известен также способ прошивки слитков иа трехвалковом стане, включающий деформацию иагретой заготовки трем валками перед оправкой и деформацию на оправке 2.There is also known a method of flashing ingots of a three-roll mill, including the deformation of the heated billet with three rollers in front of the mandrel and the deformation on the mandrel 2.
Недостаток способа заключаетс в том, что осуществл емое при прошивке незначительное обжатие слитка перед носком оправки, необходимое дл захвата заготовки, не обеспечивает гомогенность структуры и увеличивает врем прошивки.The disadvantage of the method lies in the fact that the slight compression of the ingot before the toe of the mandrel necessary for gripping the workpiece carried out during the piercing does not ensure the homogeneity of the structure and increases the flashing time.
Цель изобретени - повышение производительности и качества получаемых изделий.The purpose of the invention is to increase the productivity and quality of the products obtained.
Указанна цель достигаетс тем, что при прошивке в трехвалковом стане деформацию перед носком оправки осуществл ют с обжатием 35-80%.This goal is achieved by the fact that when flashing in a three-roll mill, the deformation in front of the toe of the mandrel is performed with a compression of 35-80%.
Способ реализуетс следующим образом.The method is implemented as follows.
Нагретый до температуры прокатки слиток или непрерывно лита заготовка задаетс в валки трехвалкового стана, где осуществл етс предварительна деформаци металла. Дл прошивки по предлагаемому способу используют трехвалковый стан, у которого валки устанавливают на угол подачи 8-25°. При этом до An ingot or continuously cast billet heated to the rolling temperature is set into rolls of a three-roll mill where the metal is pre-deformed. For the firmware of the proposed method, a three-roll mill is used, in which the rolls are set at a feed angle of 8-25 °. With this up to
10 того, как слиток доходит до оправки, его обжимают , уменьша площадь поперечного сечени на 35-80%. Дальнейша деформаци осуществл етс валками на оправке.10, as the ingot reaches the mandrel, it is crimped, reducing the cross-sectional area by 35-80%. Further deformation is carried out by rolls on the mandrel.
После обжати и прошивки всего слитка After crimping and flashing the entire ingot
15 получают изделие с гомогенной структурой по продольному и поперечному сечени м при минимальном времени обработки.15, a product with a homogeneous structure along the longitudinal and transverse sections with the minimum processing time is obtained.
Конкретна величина обжати при деформации перед носком оправки зависит от угла The specific amount of compression during deformation in front of the toe of the mandrel depends on the angle
Ю подачи, калибровки валков и размеров заготовки . Деформаци перед носком оправки с обжатием менее 35% не обеспечивает улучшение качества структуры издели . Обжатие болееYu feed, calibration rolls and workpiece sizes. Deformation in front of the toe of the mandrel with a compression of less than 35% does not provide an improvement in the quality of the structure of the product. Compressing more
80% приводит к значительному повышению усилий и поломкам оборудовани .80% leads to a significant increase in effort and equipment breakdowns.
