Description
Изобретение относитс к области металлургии , в частности к разливке металлов.The invention relates to the field of metallurgy, in particular to the casting of metals.
Известны способы получени биметаллических заготовок последовательной заливкой двух металлов в специальную двухсекционную изложницу (кокиль). Недостатком указанных способов вл етс высока трудоемкость процесса , низкие производительность и выход годной продукции из-за обрези головной и хвостовой частей заготовок.Known methods for producing bimetallic billets by successive pouring of two metals into a special two-section mold (chill mold). The disadvantage of these methods is the high labor intensity of the process, low productivity and yield of products due to trimming of the head and tail parts of the blanks.
Цель изобретени - обеспечение стабильности процесса, получение заготовок высокого качества и высокого выхода годной продукции . Дл этого предлагаетс способ получени термобиметаллических заготовок, при котором металл с меньшей темнературой плавлени заливают при температуре поверхности заготовки из металла с более высокой температурой плавлени на 10-100°С ниже температуры ликвидуса металла с меньшей температурой плавлени .The purpose of the invention is to ensure the stability of the process, obtaining high quality blanks and high yield of useful products. For this, a method is proposed for producing thermo-bimetallic billets, in which a metal with a lower melting temperature is poured at a surface temperature of a billet of metal with a higher melting temperature 10-100 ° C below the liquidus temperature of a metal with a lower melting temperature.
Экспериментальна проверка данного способа была проведена в лабораторных услови х , дл чего была собрана установка, состо ща из двух плавильных печей емкостью по 50 кг. Заливка металла осуществл лась в медный водоохлаждаемый совмещенный кристаллизатор , у которого одна стенка, после заливки нервой составл ющей, отодвигалась рычажным механизмом, чем создавалась полость дл An experimental test of this method was carried out under laboratory conditions, for which an installation consisting of two 50 kg melting furnaces was assembled. The metal was poured into a copper water-cooled combined mold, in which one wall, after the nerve component was cast, was moved away by a lever mechanism, thus creating a cavity for
второй составл ющей. Измерение температуры металла производили с помощью термопар, заливаемых металлом и оптическим пирометром . Эксперименты проводили на термобиметалле марки ТБ-2013, состо щего из сплава Н36 - пассивна составл юща и 75ГНД - активна составл юща . Средн температура ликвидуса соответственно: дл Н36 - 1450°С, дл 75ГНД - 1075°С.the second component. The temperature of the metal was measured using thermocouples filled with metal and an optical pyrometer. The experiments were carried out on a thermo-bimetal of the TB-2013 brand, consisting of an alloy of H36 — the passive component and 75GND — the active component. The average liquidus temperature, respectively: for H36 - 1450 ° C; for 75 GND - 1075 ° C.
Первой составл ющей заливали сплав П36, после чего, по достижении поверхности отлитой заготовки температуры 1020-1050°С, заливали в осБободивш уюс полость сплав 75ГНД. Проведенные эксперименты показалиThe first component was cast alloy P36, after which, when the surface of the cast billet reached the temperature of 1020–1050 ° C, the alloy 75GND was poured into the free-standing cavity. Experiments have shown
достаточную прочность сварного соединени и отсутствие его заметного размыти . Заливка второй составл ющей (75ГНД) при температуре более 1070°С приводила к смешиванию металла, при температуре ниже 975°С - кsufficient strength of the welded joint and the absence of its noticeable blurring. Filling the second component (75GND) at a temperature of more than 1070 ° C led to mixing of the metal, at a temperature below 975 ° C - to
расслоени м (отсутствие сваривани ).delamination m (lack of welding).
