Description
Босредотвом предлагаемого способа имеетс в виду достигнуть получени чугуна с малым содер:1:анием серы, иследствие чего, как известно, значительно понижаетс брак, вызванный трещ нам , раковинами и т. п.By the medium of the proposed method, it is intended to achieve the production of low-grade cast iron: 1: sulfur, and as a result, as it is known, rejects caused by cracks, shells, etc., are significantly reduced.
ииакое содержание серы . благоири т (твуот созданию услови получени от;гнвок бе усадочных раковнн, которые легко образуютс при высоком содержа ) н ее в отливках. Результаты многочисле )нык исследовательских работ сход тс в том, что сера, особенно в форме сернистого желеаа, благопри тствует отбеливанию лить , вызывает образование в нем твердых мест и сильно понижает его :к 1дкоилавкость, что дл некоторых тлпвок может быть роковым. Таким о6ра;зом, сера значительно ионижает литейные качества чугуна.and sulfur content. blessed (creating conditions for obtaining from; shrink-free shanks, which are easily formed at high contents) and in its castings. The results of many research papers agree that sulfur, especially in the form of sulphurous gel, favors bleaching casting, causes the formation of hard spots in it and greatly reduces it: to 1 degree of viscosity, which may be fatal for some tlpvvok. Thus, sulfur, sulfur significantly ionizes the casting qualities of cast iron.
По предлагаемому обессерипани чугуна копильник, в котором иро11 ,водитс обессеривание, должен иметь та1со( устроГ ство, чтобы кислые шлаки, получающиес в вагранке, удал лись ,- о, чем они иопадут в копильник. утеровку коиильника следует сделать -л основных материалов. Копильник должен иметь патрубок дл введени чог1т i-rr обессеривающих реагентов.According to the proposed desulfurization of cast iron, the digger, in which iro11, the desulfurization is carried out, must have such an arrangement (that the acidic slags produced in the cupola are removed, oh, what they do into the accumulator. The cleaning of the fixture should be done in basic materials. should have a nozzle for the introduction of chowl i-rr desulfurizing agents.

For this purpose, the hoods and an iodine umbrella with a chimney are removed, the slag is removed, then the system is introduced: 1) aeOHTH in the following proportion, as is the niiH desulfurization process.
