Изобретение относитс к сталеилавильноМУ производству.The invention relates to steel-making industry.
Нзвестен снособ производства литой марганцевой стали нри основном металлургическом процессе. В жидкий сплав химического состава, определенного стандартами, ввод т алюминий дл раскислени ванны и размельчени структуры, а также титан дл св зывани азота в устойчивые межметалличеокие соединени . Така сталь в необработанном состо нии носле отливки имеет аустенитную структуру с многочисленными включени ми карбидов. Дл иолучени однородной аустенитной структуры без карбидов производ т термообработку, состо щую в продолжительной выдержке при 1323-1353°К с последующим охлаждением в воде.Known is the method of production of cast manganese steel at the main metallurgical process. Aluminum is introduced into the liquid alloy of the chemical composition defined by the standards for the deacidification of the bath and the grinding of the structure, as well as titanium for the binding of nitrogen into stable inter-metal compounds. This raw steel, in its unprocessed state, has austenitic structure with numerous inclusions of carbides. In order to obtain a homogeneous austenitic structure without carbides, heat treatment is carried out, which consists in prolonged aging at 1323-1353 ° K, followed by cooling in water.
С целью иовышени ударной в зкости литой стали предлагаетс вводить в нее присадку жидкой сурьмы в .количестве 0,01-0,5 вес.In order to raise the impact strength of cast steel, it is proposed to add an additive of liquid antimony in the amount of 0.01-0.5 weight.
%. Сурьма может быть введена в жидкий .металл в печи или в сталеразливочном ковше. Введепие сурьмы в жидкий металл обуславливает получение аустенитной структуры с% Antimony can be introduced into the liquid metal in a furnace or in a casting ladle. The introduction of antimony in the liquid metal causes the formation of austenitic structure with
небольшим количество.м выделенных карбидов .a small amount. m of isolated carbides.
Термообработку отливок из такой ста.ти производ т при тех же температурах, но при значительно укороченной выдержке или жеHeat treatment of castings of this type is carried out at the same temperatures, but with a significantly shortened exposure or
при заниженных температурах (1223-1273°К) и нри неизменной выдержке.at low temperatures (1223-1273 ° K) and at constant shutter speed.
Предмет изобретени Subject invention
Способ модифицировани литой марганцевой стали, заключающийс в вводе модификатора в расплав, отличающийс тем, что, с целью увеличени ударной в зкости стали, в качестве модификатора ввод т сурьму в количестве 0,01-0,5 вес. %.The method of modifying cast manganese steel, which consists in introducing a modifier into the melt, characterized in that, in order to increase the toughness of the steel, antimony is added as an modifier in an amount of 0.01-0.5 wt. %
