(54) СПОСОБ ПОЛУЧЕНИЯ КОВАНО-СВАРНЫХ ИЗДЕЛИЙ(54) METHOD FOR GETTING WOOD-WELDED PRODUCTS
Изобретение относитс к обработке .металлов давлением, а именно к способам получени ковано-сварных изделий, и может быть использовано в т желом и энергетическом мгилиностроении.The invention relates to the processing of metals by pressure, in particular to methods for producing forged-welded products, and can be used in heavy and energetic construction.
Известен способ получени кованосварных изделий, включающий ковку отдельных элементов ступенчатой формы , их сварку между собой и оконча тельную ковку сваренного блока 1.A known method for producing wrought-iron products includes forging individual elements of a stepped shape, welding them together and finally forging the welded block 1.
Недостатком известного способа вл етс невысокое качество получаемых изделий.The disadvantage of this method is the low quality of the products obtained.
Цель насто щего изобретени - повышение качества получаемых изделий за счет обеспечени возможности получени однородности свойств металла в зоне сварки.The purpose of the present invention is to improve the quality of the products obtained by ensuring that the properties of the metal in the welding zone are homogeneous.
С этой целью, при получении ковано-сварных изделий способом, включающим ковку отдельных элементов ступенчатой формы, их сварку между собой и окончательную ковку сваренного блока, при ковке отдельных элементов на боковой их поверхности со стороны свариваемого торца формуют кольцевой ус туп с соотношени ми Ъ/И 0,05...0,15 и ,03.. .0,15, где - высота уступа, Н - размер ступени максимального диаметра, Р - длина уступа, аTo this end, when producing forged-welded products by a method that includes forging individual elements of a stepped form, welding them together and final forging the welded block, forging individual elements on their lateral surface from the side of the welded end, an annular joint is formed with the ratios b / And 0.05 ... 0.15 and, 03 .. .0.15, where is the height of the ledge, H is the size of the step of maximum diameter, P is the length of the step, and
ковку сваренного блока начинают с поочередного деформировани ступеней.The forging of the welded block begins with the alternate deformation of the steps.
В св зи с тем, что после сварки пластические свойства металла перегретой околошовной зоны и металла шва на 40-70% ниже аналогичных характеристик основного металла, дл достижени после ковки одинаковых свойств соединени необходимо зону шва про10 деформировать с относительным обжатием Ё(е -) где лЪ - абсолютное сжатие)- на 10-30% меньше, чем околошовную зону. Такую разницу в обжатии шва и околошовной зоны обеспечива:ет выполнение уступа с параметрами - Due to the fact that after welding the plastic properties of the metal of the superheated heat-affected zone and the weld metal are 40-70% lower than the similar characteristics of the base metal, to achieve the same properties of the joint after forging, it is necessary to deform the weld zone 10 with relative crimping E (e) where lb - absolute compression) - 10-30% less than the heat-affected zone. This difference in the reduction of the seam and the heat-affected zone provides: em implementation of the ledge with the parameters -

Самые низкие механические свойства перегретой околошовной зоны наблюдаютс на рассто нии (О,05. . .О , 20)Н The lowest mechanical properties of the superheated heat-affected zone are observed at a distance of (O, 05... O, 20) H

In this connection, it is necessary to perform a step with a relative length of 0.03 ... 0.15. Alternately, forging steps beyond the welded joint provides for the development of the joint zone throughout the volume under the scheme of the stressed state of the axial compression, which contributes to the welding of welding defects and intensive development of the superheated
