Description
Vynález sa týká médi pre chladiarenské rúrky a sposobu jej výroby.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to refrigerant tube media and to a process for the manufacture thereof.
Súčasne vyrábaná meď obsahujúci kyslík nie je použitelná v procese technologického spracovania, tj. oxidačno-redukčného žíhania, ktoré chladiarenský priemysel používá. Nevhodnost tejto médi pre oxidačno-redukčné žíhanie (ohřev) spočívá v tom, že pri žíhaní (ohřeve) v redukčnej atmosféře obsahujúcej vodík, dochádza k difúzii atomárneho vodíka do médi, vzniká vodná para, ktorá v médi nie je rozpustná ani schopná difúzie, a spĎsobuje interkryštalické porušenie a jej netesnosť, ktorá pre výrobu chladiarenského priemyslu je vyžadovaná. Ako dezoxidačný prvok sa využíval fosfor.The currently produced oxygen-containing copper is not usable in the process of processing; oxidative-reduction annealing used by the refrigeration industry. The suitability of this medium for oxidation-reduction annealing (heating) lies in the fact that annealing (heating) in a hydrogen-containing reducing atmosphere results in atomic hydrogen diffusion into the medium, producing water vapor which is neither soluble nor capable of diffusion in the medium, and causes intercrystalline failure and leakage required for the refrigeration industry. Phosphorus was used as a deoxidizing element.
Uvedené nedostatky odstraňuje meď pre chladiarenské rúrky, ktorá pozostáva v % hmotnosti minimálně z 99,9 °/o médi a z fosforu, pričom obsah primiešaním je stopový až do 0,001 % bizmutu, 0,001 % síry, 0,002 % niklu, 0,002 % antimonu, 0,002 % arzenu, 0,002 % cínu, 0,005 % olova, 0,005 % železa a 0,008 % zinku podfa vynálezu, ktorého podstata spočívá v tom, že je legovaná fosforom na množstvo 0,015 až 0,040 % hmotnosti. Ďalej podstata vynálezu spočívá v tom, že legovanie taveniny médi fosforom sa vykonává až po jej dezoxidácii dřeveným chlím.These drawbacks are remedied by copper for refrigeration tubes, which consists in% by weight of at least 99.9% by weight of the medium and phosphorus, with a trace content of up to 0.001% bismuth, 0.001% sulfur, 0.002% nickel, 0.002% antimony, 0.002% arsenic, 0.002% tin, 0.005% lead, 0.005% iron and 0.008% zinc according to the invention, characterized in that it is alloyed with phosphorus to an amount of 0.015 to 0.040% by weight. A further object of the invention is that the alloying of the melt with the phosphorous medium is carried out only after its deoxidation with wood-based hair.
Výhody médi podfa vynálezu sú v tom, že neobsahuje kyslík, čo sposobuje jej legovanie fosforom a tým pri jej ohřeve v redukčnej atmosféře nedochádza k interkryštalickému porušeniu v dosledku vzniku vodnej páry. Zároveň pri žíhaní v oxidačnej atmosféře zaručený obsah fosforu v medl zabezpečuje antioxidačnú odolnost takejto médi.Advantages of the medium according to the invention are that it does not contain oxygen, which causes it to be alloyed with phosphorus and thus, when heated in a reducing atmosphere, there is no intercrystalline failure due to the formation of water vapor. At the same time, during annealing in an oxidizing atmosphere, the guaranteed phosphorus content in the medl ensures the antioxidant resistance of such a medium.
Příklad chemického zloženia médi podfa vynálezu v % hmotnosti: je 99,2 % médi, 0,037 % fosforu, stopy až 0,0001 % bizmutu, 0,0001 % olova, 0,0001 % mangánu, 0,001 °/o cínu, 0,002 % niklu, 0,003 % železa, 0,008 % zinku, 0,001 % arzénu a 0,002 % antimonu. Dezoxidácia taveniny médi sa uskutočnila suchým dřeveným uhlím v taviacej peci po dobu 25 minút. Legovanie fosforom sa uskutočnilo formou predzliatiny CuPlO v liacej jednotke.Example of chemical composition of media according to the invention in% by weight: is 99.2% media, 0.037% phosphorus, traces up to 0.0001% bismuth, 0.0001% lead, 0.0001% manganese, 0.001% tin, 0.002% nickel , 0.003% iron, 0.008% zinc, 0.001% arsenic and 0.002% antimony. The melt deoxidation with the medium was performed with dry charcoal in a melting furnace for 25 minutes. Phosphorus alloying was carried out in the form of a CuP10 alloy in the casting unit.
