Сокращение цнкла отжига белого ч гуна, перерабатываемого Fia -ковKHii , может быт достигнуто путем увелм1ер(и ко.гпгчества кремни , в )езультате чего сильно уменьшаетс период распада цементита в чугуне II соответствен} о этому может быть ускорен отжиг отливок. Однако содержание кремни в белом чугуне не удавл.чось повысить более до 1,3% без того, чтобы не вызвать в отливке образовани лекачественггой структуры серого чугуна (что обусловлено выделением пластинчатого графита).The reduction of the annealing tscl of the white h of the guna processed by Fia -kovKHii can be achieved by increasing (and co-silicon, c) the result of which the decomposition of cementite in cast iron II is greatly reduced, annealing of the castings can be accelerated. However, the content of silicon in white iron did not hesitate to increase to more than 1.3% without causing the formation of gray iron in the quality of the cast iron structure (due to the release of lamellar graphite) in the casting.
Согласно предлагаемому способу возможность увеличени количества кремни до 1,6-2,2% в чугуне достигаетс путем введени 0,01-According to the proposed method, the possibility of increasing the amount of silicon to 1.6-2.2% in cast iron is achieved by introducing 0.01-
0,04% магни . При этих соотиои1енн х мапип) св зывает кремнии и не дает ему при затвердеванин отлнвки действовать как грас|1нтиз;п-ору, чем и обеспечиваетс получение в литье структуры белого чугуна.0.04% magnesium. With these correspondingly x-type, it binds silicon and prevents it from hardening to act as a granule; as an example, this provides for the production of white iron in the casting.
Ввод магни в чугун может быть осуществлен путем присадки в жидкии чугун до 1 % лигатуры, состо щей из магнн и ферросилици , или присадки до 0,4% лигатуры, состо щей из магж( и никел или медн.Magnesium can be added to cast iron by adding to liquid iron up to 1% of a ligature consisting of magnesia and ferrosilicon, or an additive up to 0.4% of a ligature consisting of magi (and nickel or copper.
Перва присадка рекомендуетс дл жидкого чугугта с температурой, не превышающей , вторую целесообразно примен ть дл чугуна более высокой температуры. Дл улучгнени литейных свойств и более надежного усвоени магни содержание углерода следует иметь около 3%. The first additive is recommended for liquid iron with a temperature not exceeding, the second is advisable to use for a higher temperature iron. In order to improve the casting properties and more reliable assimilation of magnesium, the carbon content should be about 3%.
Преимуществом кремнистого ковкого чугуна, полученного предлагаемым способом, вл етс сокращение продолжительности выдержки при отжиге (960°) до 5 часов. Кремнистый ковкий чугун допускает , кроме того, возможность проводить отжиг при более высоких температурах (1050 и выиге).The advantage of the silicon ductile iron obtained by the proposed method is a reduction in the duration of annealing (960 °) to 5 hours. Silicon malleable cast iron also permits annealing at higher temperatures (1050 and win).
