Description
Уменьшение остаточных напр жений в металлических отливках достигаетс обычно отжигом (при стальном литье) или высоки1М отпуском (при сером чугупе). Эти операции вл ютс дорогими и длительными и дл их выполнени требуетс специальное оборудование.The reduction of residual stresses in metal castings is usually achieved by annealing (with steel casting) or high tempering (with gray cast iron). These operations are expensive and time consuming and require special equipment to perform them.
В отличие от упом нутых способов сн ти внутренних напр жений в металлических отливках, предлагаетс небольшой участок одного из элементов литой конструкции подвергать быстрому и кратковременному нагреву до пластического состо ни (т. е. до красного калени 750-800°). In contrast to the aforementioned methods of relieving internal stresses in metal castings, it is proposed to subject a small portion of one of the cast construction elements to rapid and short-term heating to a plastic state (i.e., 750-800 ° red face).
Под воздействием имеющихс в отливке внутренних напр жений происходит пластическа деформаци раст жени , сжати или изгиба отливки в нагретом месте, благодар чему напр жени в системе резко уменьшаютс .Under the influence of internal stresses in the casting, plastic deformation of the casting, compression or bending of the casting takes place in a heated place, due to which the stresses in the system decrease sharply.
Местный нагрев отдельных участков отливки можно осуществл ть при помош,и одной или двух сварочных горелок.Local heating of individual sections of the casting can be carried out with a help, and one or two welding torches.
Предмет изобретени Subject invention
Способ сн ти внутренних напр жений в металлических отливках путем местного их подогрева, отличающийс тем, что нагрев ведут до доведени металла до пластического состо ни .The method of removing internal stresses in metal castings by local heating them, characterized in that the heating is carried out to bring the metal to a plastic state.
