Description
Известные до сих пор сорта аустенитного чугуна по существу вл отс серыми аустенитными чугунами, т. е. такими, в которых свободны углерод находитс в виде графита, причем количество углерода, марганца и кремни подбираетс таким образом, чтобы количество углерода составл ло от 3 до 4% и кремни от 2,4 до 3%.The austenitic cast iron grades so far known are essentially gray austenitic cast irons, i.e., those in which the free carbon is in the form of graphite, and the amount of carbon, manganese and silicon is adjusted so that the amount of carbon is from 3 to 4 % and silicon from 2.4 to 3%.
Предлагаемое изобретение имеет целью получение изделий из такого аустенитного чугуна, в которых углерод содержалс бы не в виде графита , а в виде углерода отжига. Дл этого чугун в отливке получатьс белым и графитизироватьс при помощи специального отжига.The present invention aims to produce products from such austenitic cast iron, in which carbon would be contained not in the form of graphite, but in the form of carbon annealing. For this, cast iron in the casting is obtained white and graphitized by special annealing.
Дл получени такого аустенитного ковкого чугуна, согласно :зобретеиию , издели отливают из .металла, содержащего 2-3% С. 1-3% Si, 7-10% Мп и 0-2% Си и подвергают однократной графитпзаини при 1000-1500 в течение 30-60 час.To obtain such austenitic ductile iron, according to: the invention, the product is cast from a metal containing 2-3% C. 1-3% Si, 7-10% Mn and 0-2% Cu and subjected to a single graphitzini at 1000-1500 V for 30-60 hours
Получающийс аустенитный ковкий чугун нар ду с немагннтиостью и антикоррозийностью обладает высокой ударной в зкостью и может быть использован дл деталей, работающих на удар. В частности, он может быть использоваи в качестве антифрикииоиного материала, так как оп сочетает в себе в зкость и износоупориость.The resulting austenitic malleable cast iron, along with non-magnetism and anti-corrosion properties, has high impact strength and can be used for impact parts. In particular, it can be used as an antifriction material as it combines viscosity and wear resistance.

Способ получени изделий из аустенитного ковкого чугуна, отл 1чающийс тем, что издели отливают, с целью получени белого излома , из металла, содержащего 2-3% С. 1-3% Si, 7-10% Мп и О-2% Си, н подвергают однократной графитизации при 1000-1050 в течение 30-60 час.The method of obtaining products from austenitic ductile iron, which is based on the fact that the products are cast, with the aim of obtaining a white fracture, from a metal containing 2-3% C. 1-3% Si, 7-10% Mn and O-2% Cu, n is subjected to a single graphitization at 1000-1050 for 30-60 hours.
