Description
Изобретение от1НооИтс к способу электроко-нтактной обработки наплавленных твердых сплавов типа сормайт, р-элит, сталинит и других.The invention of ot1OoIt to the method of electro-contact processing of deposited hard alloys such as smorite, r-elite, stalinite and others.
Известен электроконтактный способ обработки наплавленных твердых сплавов на стальную основу. Однако лр,и таком способе возникает повышенный нагрев поверхностного сло . Это лриводит к трещинообразо-ваийю в твердом сплавэ вследствие высокой скорости нагрева, ра зличных коэффициентов линейного расширени основного и наплавочного металлов.Known electrocontact method of processing the deposited hard alloys on a steel base. However, lr, and in this way there is an increased heating of the surface layer. This leads to a crack in the hard alloy due to the high heating rate, different coefficients of linear expansion of the base and surfacing metals.
Предложенный способ отличаетс от известного тем, что обрабатываемую деталь или часть ее подогревают до температуры, при которой коэффициенты линейного расширени основного и наплавленного материалов близки по своему значению.The proposed method differs from that known in that the workpiece or part thereof is heated to a temperature at which the linear expansion coefficients of the base and weld materials are close in value.
Это уменьшает количество трещин в наплавленном слое при электроконтактной обработке .This reduces the number of cracks in the weld layer during electrocontact processing.
После Наплавки сормайта иа ст. 30, ст. 35, ст. 35Л деталь подогревают до температуры 130-270°С, так как коэффициенты лиеейного расширени ст. 30, ст. 35, ст. 35Л и твердого сплава сормайт-1 одинаковы пр,и этой температуре.After surfacing of sormait art. 30, art. 35, art. 35L detail is heated to a temperature of 130-270 ° C, since the coefficients of the linear expansion of st. 30, art. 35, art. 35L and smortite-1 hard metal are the same, and this temperature.
ли Ё процессе наплавки с электроконтакпгой обработкой в зоне вышеуказанных темпгратур .Is it a process of surfacing with electric contact processing in the area of the above temperature patterns.
В результате применени предложен}1ого способа электроконтактной обработки наплавленных твердых сплавов с подогревом уменьшаетс количество трещин, что увеличивает долговечность и улучшает качество обрабатываемой детали, так как на конусах засыпных аппаратов доменного оборудовани трещина в износостойком конактном слое сормайт-1 вл етс очагом продува и прогара конуса.As a result of the application, the first method of electrocontact treatment of the deposited hard alloys with heating reduces the number of cracks, which increases durability and improves the quality of the workpiece, since the cones of the charging equipment of the blast furnace equipment crack in the wear-resistant contact layer of Sormite-1 is a center of blowing and heating of the cone .
