Description
Изобретение относитс к обработке металлов цавлением. Известен способ изготовлени железн порожных колес, состо щий из нагрева заготовки, ее формовки с образованием ступицы, обода и диска и последующей прокатки {ij. Однако в готовых издели х, изготовленных из стали с повышенным содержанием водорода по этому способу, содержатс флокены. Наиболее близким по технической сущ ности и достигаемому результату к изо ретению вл етс способ изготовлени цельнокатаных железнодорожных колес путем нагрева заготовки, ее формовки,. прокатки колеса и последующей противо- флокенной обработки 2. Противофлокен ную обработку осуществл ют путем изотермической выдержки заготовки при 60О-650 С в течение 2-4 ч после прокатки заготовки. Однако этот способ также не обеспе чивает получени изделий, не содержащих флокенов. Цель изобретени - повышение качества изделий. Цель достигаетс тем, что по предлагаемому способу противофлокенную обработку производ т в два этапа, причем первый этап осущвг:твл ют при нагреве путем изотермической выдержки заготовки в течение 3-е ч при 600-680°С. Способ осуществл етс следующим образом. Колесные заготовки, полученные, например , путем порезки слитка, нагревают до 122О-126О С. В период нагрева заго- тосок под деформацию при 650-680° осуществл ют первый этап противофлокенной обработки - изотермическую выдержку в течение 3-6 ч. Нагретые заготовки под- вергают гор чей деформации до получени полуфабриката. В этот период ведут осадку .заготовок (предварительную и окончательную ), их разгонку и формовку .сThe invention relates to the treatment of metals by pressurization. A known method of manufacturing iron empty wheels consists of heating the billet, molding it to form a hub, a rim and a disk, and then rolling {ij. However, in the finished products made of steel with a high content of hydrogen by this method, there are flocs. The closest in technical essence and the achieved result to the invention is a method of manufacturing solid-rolled railway wheels by heating the billet, its molding ,. rolling the wheel and subsequent anti-flock treatment 2. The anti-floc treatment is carried out by isothermal holding the workpiece at 60 ° C to 650 ° C for 2-4 hours after rolling the workpiece. However, this method also does not provide for the production of products that do not contain floken. The purpose of the invention is to improve the quality of products. The goal is achieved by the fact that according to the proposed method, the anti-flocation treatment is carried out in two stages, the first stage being the implementation: heating is carried out by isothermal holding of the workpiece for 3 h at 600-680 ° C. The method is carried out as follows. Wheel blanks, obtained, for example, by cutting an ingot, are heated to 122 ° –126 ° C. In the period of heating the billets for deformation at 650–680 °, the first stage of anti-flocculation is carried out — isothermal holding for 3–6 h. - cast hot deformation to obtain a semi-finished product. During this period, precipitation of preforms (preliminary and final), their distillation and molding are carried out.
