Przedmiotem wynalazku jest sposób wytwarzania stopu wstepnego miedz-tellur.Dotychczas znany sposób wytwarzania stopów miedzi z tellurem polega na stopieniu miedzi w piecu opalanym gazem i wprowadzeniu do kapieli pokrytej zuzlem telluru w postaci kawalków meta¬ licznych lub proszku.Stosowane sa tez metody wtapiania telluru do kapieli w rurkach miedzianych dla unikniecia utle¬ niania sie tego metalu.Sposoby te prowadza do utleniania sie telluru, co obniza jakosc stopu wstepnego i prowadzi do du¬ zych strat bezpowrotnych tego metalu oraz nie zabezpieczaja one przed choroba wodorowa tego stopu.Celem wynalazku* jest wyeliminowanie wad i nie¬ dogodnosci technicznych znanych i stosowanych sposobów sporzadzania stopów miedzi z tellurem.Cel ten zostal osiagniety w ten sposób, ze na dno pieca indukcyjnego elektrycznego posiadajacego ty¬ giel grafitowy laduje sie proszek telluru zasypujac go otoczka miedziana. Tak przygotowany wsad topi sie pod pokryciem wegla drzewnego uwazajac aby temperatura stopu nie przekraczala 1040°C, a czas wytopu nie przekraczal 60 minut.Po stopieniu do kapieli wprowadza sie fosfor w postaci zaprawy miedz-fosfor dla odtlenienia stopu oraz celowego wprowadzenia do stopu wstepnego od 0,4 do 1% fosforu, co poprawia wlasnosci uzyt¬ kowe stopu. Taik przygotowany stop wstepny za- 10 15 20 30 wiera 0,4 do 1,0% fosforu, 45 do 55% telluru i resz¬ te miedzi. Stop odlewa sie z pieca do form zeliw¬ nych.Zasadnicze korzysci techniczne wynikajace ze sto¬ sowania wynalazku polegaja na zmniejszeniu o 50% strat bezpowrotnych, niedopuszczeniu do tworzenia sie potrójnej eutektyki obnizajacej jakosc stopu oraz poprzez wprowadzenie fosforu i zabezpieczenie przed choroba wodorowa (pekanie w srodowisku wodoru) stopu.Przedmiot wynalazku zostal przedstawiony w przykladzie wykonania. Na dno tygla grafitowego umieszczonego w indukcyjnym piecu elektrycznym laduje sie 25 kg proszku telluru przysypujac go 25 kg otoczki miedzianej poprzednio wysuszonej i odmagnesowanej. Po stopieniu i przykryciu warstwa wegla drzewnego do kapieli metalowej wprowadza sie fosfor w ilosci 0,4 kg w postaci zaprawy CuP8.Czas topienia lacznie z wtapianiem CuP8 wynosi 50 minut. Po stopieniu i sciagnieciu zuzla metal odlewa sie do form zeliwnych w tak zwane kostki.Zastrzezenia patentowe 1. Sposób wytwarzania stopu wstepnego miedz- -tellur zawierajacego od 45 do 55% telluru, zna¬ mienny tym, ze na dno tygla grafitowego umiesz¬ czonego w indukcyjnym piecu elektrycznym laduje sie proszek telluru i przykrywa warstwa otoczki 106908106 908 3 4 miedzianej, a po stopieniu stopu wprowadza sie mienny tym, ze czas wytopu stopu pod pokryciem fosfor w postaci zaprawy miedz-fosfor w ilosci wegla drzewnego nie moze przekraczac 60 minut, 0,4 do 1% w stosunku do masy wsadu. a temperatura kapieli metalowej nie moze byc 2. Sposób wytwarzania wedlug zastrz. 1, zna- 5 wieksza od 1040°C.Drukarnia Narodowa, Zaklad Nr 6, zam. 1092/79 Cena 45 zl PLThe subject of the invention is a process for the production of copper-tellurium alloys. The so far known method of producing copper and tellurium alloys consists in melting copper in a gas-fired furnace and introducing it into a bath coated with tellurium in the form of metal pieces or powder. Methods of fusing tellurium into bathing in copper tubes to avoid oxidation of this metal. These methods lead to the oxidation of tellurium, which reduces the quality of the pre-alloy and leads to large irreversible losses of this metal and does not protect against hydrogen disease of this alloy. elimination of technical disadvantages and inconveniences of known and used methods for the preparation of copper-tellurium alloys. This goal was achieved in such a way that tellurium powder is charged to the bottom of an electric induction furnace with a graphite crucible, and it is covered with a copper shell. The charge prepared in this way is melted under the charcoal cover, taking care that the melt temperature does not exceed 1040 ° C, and the melting time does not exceed 60 minutes. After melting, phosphorus is introduced into the bath in the form of a copper-phosphorus mortar to deoxidize the alloy and deliberately introduce it into the pre-alloy from 0.4 to 1% phosphorus, which improves the performance of the alloy. The taik prepared pre-alloy contains 0.4 to 1.0% phosphorus, 45 to 55% tellurium and a residual copper. The alloy is poured from the furnace into cast iron molds. The main technical advantages of the invention consist in reducing irreversible losses by 50%, preventing the formation of a triple eutectic reducing the quality of the alloy, and by introducing phosphorus and preventing hydrogen disease (cracking in environment of hydrogen) of the alloy. The subject of the invention is presented in the embodiment example. On the bottom of the graphite crucible placed in an induction electric furnace, 25 kg of tellurium powder are charged over it with 25 kg of previously dried and demagnetized copper shell. After melting and covering, a layer of charcoal is introduced into the metal bath in the amount of 0.4 kg phosphorus in the form of CuP8 mortar. The melting time, including CuP8 fusion, is 50 minutes. After melting and stripping down the metal, the metal is poured into cast iron molds into so-called cubes. Claims 1. The method of producing a copper -tellur pre-alloy containing 45 to 55% tellurium, characterized by the fact that at the bottom of a graphite crucible placed in In an electric induction furnace, tellurium powder is charged and covered with a layer of copper coating 106908106 908 3 4, and after melting the alloy, a variable is introduced that the time of melting the alloy under the cover of phosphorus in the form of a copper-phosphorus mortar in the amount of charcoal cannot exceed 60 minutes, 0 , 4 to 1% in relation to the weight of the input. and the temperature of the metal bath cannot be 2. 1, greater than 1040 ° C.
