Изобретение касаетс изготовлени обработкой давлением биметаллических труб.The invention relates to the manufacture of bimetallic tubes by pressure treatment.
Известны заготовки дл изготовлени биметаллических труб, состо щие из наружного и более мелкого внутреннего слоев. Однако при более м гком внутреннем слое в начальный период прессовани или прокатки наблюдаетс значительна неравномерность послойной деформации за счет преимущественной деформации более м гкого сло , что неизбежно приводит к браку изделий.Preforms for the manufacture of bimetallic pipes are known, which consist of an outer and smaller inner layers. However, with a softer inner layer, in the initial period of pressing or rolling, there is a significant non-uniformity of the layer-by-layer deformation due to the predominant deformation of the softer layer, which inevitably leads to the rejection of the products.
Предлагаема заготовка отличаетс тем, что внутренний слой заготовки выполнен короче наружного со стороны деформации преимущественно на длину, равную 0,1-0,7 своего диаметра.The proposed preform is characterized in that the inner layer of the preform is made shorter than the outer one on the deformation side, predominantly by a length equal to 0.1-0.7 of its diameter.
На чертеже показан процесс холодной прокатки биметаллической трубы из такой заготовки на стане ХПТ.The drawing shows the process of cold rolling a bimetallic pipe from such a billet on the HPT mill.
Заготовка состоит из м гкого внутреннего 1 и твердого наружного 2 слоев, причем первыйThe preform consists of a soft inner 1 and a hard outer 2 layers, the first
короче второго на 0,1-0,7 своего диаметра. При прокатке такой заготовки (см. б) в начале происходит редуцирование наружного сло . В дальнейщем (см. в} этот радуцированный конец запирает более м гкий внутренний слой, что приводит к выравниванию послойной деформации заготовки.shorter than the second by 0.1-0.7 of its diameter. When rolling such a workpiece (see b) at the beginning, the outer layer is reduced. Subsequently (see c) this radiated end closes the softer inner layer, which leads to the alignment of the layer-by-layer deformation of the workpiece.
