I mean of the question is, we have two difference conditions parameters for the question:
1) We have a scrap for melting that there are in their chemical composition some alloying elements such as Sn, Cu, Ni. So we don't need to add this alloys elements in the melt.
Now, and the other hand,
2) we have an other type of scrap for melting that there aren't alloying elements such as Sn, Cu, Ni, in the chemical composition. So we need to add this alloys elements into the melt as a pure element.
So, this is a main question:
Are there any differences between two conditions (1, 2) from the point of view final mechanical properties such as hardness and strength in the production casting parts? please explain about that.

Предлагаю Вам ознакомиться с работами В.А. Чайкина:" Повышение механических свойств серых чугунов" в журнале "Литейное производство", 2002, №7, стр.9-11 ,а также с его диссертацией по специальности 05.16.04, 2011 г.
Предпочтительнее стальной лом высокой степени чистоты без цинка, меди и других примесей. Легированный лом не пригоден для производства чугуна. Смотрите статью G. Dybowski и другие "Влияние различных видов лома на процесс плавления при производстве чугуна в индукционных печах", Литейщик России,2004, №11, стр.4-12.
Sorry Dear,
I couldn't understand this language. Could you writ in English? And you can tell me, what is this language.
Best Regards
Translation of Mr Валерий Конкордиевич Чуркин:
I suggest you familiarize yourself with the works of V.А. Chaykina: "Improving the Mechanical Properties of Gray Cast Iron" in the journal "Foundry Production", 2002, No. 7, pp. 9-11, and also with his thesis on the specialty 05.16.04, 2011.
Preferably steel scrap of high purity without zinc, copper and other impurities. The alloyed scrap is not suitable for the production of cast iron. See article G. Dybowski and others "Influence of different types of scrap on the melting process in the production of cast iron in induction furnaces", Foundryman of Russia, 2004, N11, p.4-12.
