Pierwszenstwo: 10.12,1971 i(P. 152068) Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 03.02.1975 74394 KI. 40b,l/06 MKP C22c 1/06 CZYTELNIA U- edu P^*<*n*":r Twórcy wynalazku: Wladyslaw Augustyn, Stanislaw Jura, Markos Botton, Nikolow Nikola Uprawniony z patentu tymczasowego: Politechnika Slaska im. Wincente¬ go Pstrowskiego, Gliwice (Polska) Sposób wytapiania stopów miedzi Przedmiotem wynalazku jest sposób wytapiania stopów miedzi z zastosowaniem topników.Dotychczas dla otrzymania stopu miedzi dodaje sie topniki skladajace sie z boraksoi, fluorkówi krze¬ mionki. Udzial poszczególnych skladników jest róz¬ ny i tak dobrany, aby uzyskac najnizsza tempera¬ ture topnienia przygotowanej mieszanki. Topnik po roztopieniu ochrania ciekly metal przed utlenieniem, oraz oczyszcza kapiel metalowa rozpuszczajac tlen¬ ki. Zawartosc tlenków w topniku moze dochodzic do 50%. Przed zalaniem form, topniki wraz z tlen¬ kami metali, sciaga sie z tygla w postaci tak zwa¬ nego zgaru.Wada znanego sposobu sa duze straty miedzi i in¬ nych metali. <2elem wynalazku jest otrzymanie stopów miedzi o Jak najnundejsziej ilosci zgarju ii zawartosci gazów.Cel ten zostal Gsiagniety przez zastosowanie do wytapiania stopów miedzi topników z dodatkiem reduktora tlenków metali w postaci weglika wapnia w ilosci 5^10%.Sklad topników powinien byc tak dobrany, aby uzyskac niska temperature topnienia oraz lepkosc wynoszaca okolo 1 puasa. Weglik wapnia wchodzac w reakcje z tlenkami metali daje gazowy tlenek wegla, tlenek wapnia pozostajacy w topniku oraz metal, który wraca do kapieli metalowej.Korzystnie jest stosowac topniki o nastepujacym skladzie: 48% NaaB^O,, 20% CaF* 32% Na3AF6, lub 60% Na2B407, 40% Na3AlF6, lub 54% Na2B407, 10% CaF2, 36% NajAlF6.Po zastosowaniu topników z dodatkiem 5—10% CaC2 uzyskiuje sie topniki bez tlenków miedzi. Za¬ wartosc tlenków miedzi w tego rodzaju topnikach wynosi ponizej 0,2%.Dzieki zastosowaniu do wytapiania miedzi topni¬ ków redukcyjnych znacznie zmniejsza sie zgar me¬ talu, a równoczesnie uzyskuje sie stopy o mniejszej zawartosci gazów i o wyzszej jakosci. PLPriority: 12/10/1971 and (P. 152068) Application announced: 05/30/1973 Patent description: 02/03/1975 74394 KI 40b, l / 06 MKP C22c 1/06 READING ROOM P ^ * <* n * ": r Inventors: Wladyslaw Augustyn, Stanislaw Jura, Markos Botton, Nikolow Nikola Authorized by a provisional patent: Wincenty Silesian University of Technology Pstrowskiego, Gliwice (Poland) The method of smelting copper alloys The subject of the invention is a method of smelting copper alloys with the use of fluxes. Until now, to obtain a copper alloy, fluxes consisting of boraxoi, fluoride and silica have been added. to obtain the lowest melting point of the prepared mixture. After melting, the flux protects the liquid metal from oxidation, and cleans the metal bath by dissolving the oxides. The content of oxides in the flux may be up to 50%. Before pouring the molds, fluxes with metal oxides, it is removed from the crucible in the form of the so-called skimmage. The disadvantage of the known method is the large losses of copper and other metals. The aim of the invention is to obtain copper alloys with as many The purpose of scraping and gas content. This objective was compressed by the use of fluxes with the addition of a metal oxide reducer in the form of calcium carbon in the amount of 5 ^ 10% for smelting copper alloys. The composition of fluxes should be selected so as to obtain a low melting point and a viscosity of about 1 puasa. Calcium carbon, reacting with metal oxides, gives carbon monoxide gas, calcium oxide remaining in the flux and metal that returns to the metal bath. It is preferable to use fluxes with the following composition: 48% NaaB ^ O, 20% CaF * 32% Na3AF6, or 60% Na2B407, 40% Na3AlF6, or 54% Na2B407, 10% CaF2, 36% NajAlF6. After using fluxes with the addition of 5-10% CaC2, fluxes without copper oxides are obtained. The content of copper oxides in these types of fluxes is below 0.2%. By using reducing fluxes for copper smelting, the scratch of the metal is significantly reduced and, at the same time, alloys with lower gas content and of higher quality are obtained. PL
