Description
W przeciwienstwie do znanych sposo¬ bów, wedlug których odtlenia sie stopy metalowe, zawierajace tlen, dowolnego pochodzenia, przez dodanie srodka latwo odtleniajacego sie jak miedz fosforowa, zelazo manganowe, zelazo nakrzemione, magnez, weglik, zwykle w odlewnicy; we¬ dlug wynalazku zas osiaga sie odtlenienie, podczas wyrobu stopu lub podczas stapia¬ nia, stale pr^ez zuzle silnie odtleniajace, których zdolnosc odtleniajaca odswieza sie dodatkami.Sposób nadaje sie przedewszystkiem dla odtlenienia stopów miedzi, i bardzo jest korzystny przy pracy w piecach elek¬ trycznych.Jako srodek odtleniajacy nadaja sie, np. zuzle skladajace sie z krzemianów alka¬ licznych manganowych, których zawar¬ tosc manganu moze wynosic do 40$, w za¬ leznosci od stopnia dzialania. Zdolnosc re¬ dukcyjna utrzymuje sie na pozadanej wy¬ sokosci, podczas stapiania lub w przer¬ wach, przez dodanie wiórów metalowych, wegla, sinku potasowego, szkla wodnego, boraksu i t. p.Sposób daje nastepujace korzysci: 1. Stopy nie moga byc zanieczyszczone szkodliwym nadmiarem srodka odtlenia¬ jacego; 2. Latwo odlaczalne stopy, np.. wysoko¬ procentowy stop miedzi, i olowiu, moga byc zupelnie odtlenione i zupelnie równo¬ miernie wylane bezposrednio z pieca elektrycznego. 3. W elektrycznym piecu indukcyjnym, moga byc fazy redukcyjne przelozone wy¬ lacznie w strefe najcieplejsza i najwiecejruchliwa, oraz mozna wykorzystac wiek¬ sze dzialanie reakcji posrednich in statu nascendi. 4. Opór w piecu indukcyjnym powieksza sie a ugar zmniejsza do minimum. PL PLContrary to the known methods, whereby oxygen-containing metal alloys of any origin are deoxidized by adding a readily deoxidizing agent such as phosphorus copper, manganese iron, silica iron, magnesium, carbon, usually in a foundry; According to the invention, deoxidation is achieved, during the production of the alloy or during melting, with badly strong deoxidizing steels, the deoxidizing ability of which is refreshed by additives. The method is suitable primarily for deoxidizing copper alloys, and is very advantageous for working in furnaces As a deoxidizer, for example, badly composed of manganese alkali silicates, the manganese content of which can be up to 40 $, depending on the degree of action. The reduction capacity is maintained at the desired height, during melting or in gaps, by the addition of metal shavings, carbon, potassium blue, water glass, borax, etc. The method gives the following advantages: 1. The alloys must not be contaminated with harmful excess a deoxidizer; 2. Easily detachable alloys, eg a high percentage of copper and lead, can be completely deoxidized and completely evenly poured directly from the electric furnace. 3. In an electric induction furnace, reduction phases may be transferred only to the warmest and most agitated zone, and the greater effect of indirect reactions in statu nascendi may be used. 4. The resistance in the induction furnace increases and the yield is reduced to a minimum. PL PL
