Description
Przedmiotem wynalazku jest smar do przeróbki plastycznej na goraco, zwlaszacza do walco¬ wania rur i ksztaltowania luków gladkich krótkich metoda przepychania rur ze stali i stopów o niskiej zawartosci wegla.Dla zmniejszenia tarcia pomiedzy odksztalcanym materialem i narzedziami w przeróbce plastycznej na goraco powszechnie stosuje sie grafit w postaci suchej zasypki lub koloidalnej zawiesiny w oleju mineralnym. W przypadku stali i stopów zawierajacych malo wegla, ze wzgledu na czesciowa dyfuzje wegla do przerabianego materialu i zwiazane z tym uczulenie na korozje, zwlaszcza miedzykrystaliczna, stosowanie grafitu jest niedopuszczalne. Stad w procesach przeróbki plastycznej na goraco tych materialów próbowano stosowac jako smary rózne media, w tym stopione sole, sproszkowane metale niskotopliwe, sproszkowane szklo i inne. Stosowanie szkla przyjelo sie jedynie w procesie wyciskania rur, inne natomiast ze wzgledu na wykazywanie wlas¬ nosci smarnych w ograniczonym zakresie temperatur, czesto niskich, a takze trudnosci zwiazane z podawaniem do kotliny odksztalcania oraz z usuwaniem ich resztek z powierzchni wyrobu nie znalazly upowszechnienia jako srodki smarujace. Szerokie natomiast zastosowanie w procesach walcowania na goraco rur ze stali wysokostopowych znalazly mieszaniny fosforanów ziem alkalia- cznych znane pod handlowa nazwa „fosfatermów". Znane fosfatermy zawieraja wagowo 30 do 70% K3PO4 • 3H20, 25 do 55% (NaP03)n, do 25% A1P04. Nie spelniaja one jednak w sposób zadowalajacy swego zadania w procesach ksztaltowania luków gladkich metoda przepychania rur.Smar do przeróbki plastycznej na goraco wedlug wynalazku stanowi mieszanine zwiazków fosforu, sodu i boru ulegajacych odwodnieniu przy podwyzszonych temperaturach, charakteryzuje sie w tym, ze w suchej masie zawiera wagowo: 20 do 90% P2O5,10 do 75% Na20, maksimum 15% B2O3.Smar wedlug wynalazku w zakresie temperatur przeróbki plastycznej na goraco posiada dobre wlasnosci smarne przy braku szkodliwych efektów wtórnych obserwowanych w przypadku grafitu czy szkliw. Zaleta smaru jest równiez latwosc uzyskania go w wyniku zmieszania dostepnych na rynku zwiazków fosforu, sodu i boru takichjak fosforan jednosodowy i fosforan dwusodowy, kwas2 148 784 ortofosforowy, wodorotlenek sodu, boraks i innych. Przy podwyzszonych temperaturach zwiazki te ulegaja odwodnieniu, a przy temperaturach przeróbki plastycznej stanowia mieszanine tlenków fosforu, sodu i boru, które w obecnosci zgorzeliny w postaci plynnej spelniaja funkcje smaru wlasciwego.Smar wedlug wynalazku stosuje sie w postaci pólplynnej masy albo roztworu wodnego.Przyklad I. Smar w postaci pólplynnej masy zawiera wagowo 38% suchej masy o skladzie: 53,21% P2O5, 41,46% Na20 i 5,33% B203. Smar w postaci pólplynnej masy stanowi mieszanine zawierajaca wagowo: 69,63% Na2HP04 • 12H20, 17,41% NaH2P04 • 2H20, 5,55% Na2B407 • IOH2O i 7,41% H20. Smar stosuje sie na czolo bloczka wsadowego pod glówke przebijaka w procesie przebijania szklanek, na powierzchnie trzpienia ksztaltujacego i na powierzchnie wewnetrzna rur wsadowych w procesie ksztaltowania luków gladkich krótkich metoda przepychania i tym podobne.Przyklad II. Smar w postaci roztworu wodnego zawiera wagowo 19% suchej masy o skladzie: 52,7% P2Os, 41,3% Na20 i 6% B2C3. Roztwór smaru stanowi mieszanina zawierajaca wagowo: 24,5% H3PO4 - 60% procentowego, 9,75% NaOH, 2,75% Na2B407 • 10H2O i 63% H20. Smar w tej postaci stosuje sie na podgrzana wstepnie powierzchnie wewnetrzna odcinków rur wsadowych w procesie ksztaltowania luków gladkich krótkich metoda przepychania, na powierzchnie dragów lawy przepychowej w procesie walcowania rur i innych.Zastrzezenie patentowe Smar do przeróbki plastycznej na goraco wedlug wynalazku stanowi mieszanine zwiazków fosforu, sodu i boru ulegajacych odwodnieniu przy podwyzszonych temperaturach, znamienny tym, ze w suchej masie zawiera wagowo: 20 do 90% P205,10 do 75% Na20, maksimum 15% P203.Pracownia Poligraficzna UP PRL. Naklad 100 egz.Cena 400 zl PLThe subject of the invention is a hot-form lubricant, especially for rolling pipes and shaping short smooth hatches, a method of pushing steel pipes and low-carbon alloys. Graphite is commonly used to reduce the friction between the deformed material and hot-work tools. in the form of a dry powder or a colloidal suspension in mineral oil. In the case of steels and alloys containing little carbon, due to partial diffusion of carbon into the processed material and the associated corrosion allergy, especially intercrystalline, the use of graphite is unacceptable. Hence, in the processes of hot plastic processing of these materials, attempts were made to use various media as lubricants, including molten salts, powdered low-melting metals, powdered glass and others. The use of glass was adopted only in the process of extruding pipes, while others, due to showing lubricating properties in a limited temperature range, often low, as well as difficulties associated with feeding into the deformation basin and with removing their residues from the surface of the product, were not popularized as measures. lubricating. On the other hand, mixtures of alkaline earth phosphates known under the trade name "phosphatemes" have found widespread use in the hot rolling of high-alloy steel pipes. Known phosphatemes contain 30 to 70% by weight of K3PO4 • 3H20, 25 to 55% (NaPO3) n, up to 25 % A1PO4, however, they do not fulfill their task in smooth hatch shaping processes by the method of pushing pipes. Hot plastic working grease according to the invention is a mixture of phosphorus, sodium and boron compounds that are dehydrated at elevated temperatures, characterized by the fact that in Contains by weight of dry matter: 20 to 90% P2O5, 10 to 75% Na20, maximum 15% B2O3. The lubricant according to the invention has good lubricating properties in the range of hot forming temperatures, with no harmful secondary effects observed with graphite or glazes. it is also easy to obtain by blending commercially available phosphorus, sodium and boron compounds such as mo monosodium phosphate and disodium phosphate, orthophosphoric acid, sodium hydroxide, borax and others. At elevated temperatures, these compounds are dehydrated, and at plastic working temperatures, they constitute a mixture of phosphorus, sodium and boron oxides, which in the presence of liquid scale perform the function of a proper lubricant. According to the invention, the lubricant is used in the form of a semi-solid mass or an aqueous solution. The semi-liquid grease contains 38% by weight of dry matter with the following composition: 53.21% P2O5, 41.46% Na20 and 5.33% B203. The semi-solid lubricant is a mixture containing by weight: 69.63% Na2HPO4 • 12H2O, 17.41% NaH2PO4 • 2H2O, 5.55% Na2B407 • IOH2O and 7.41% H2O. The grease is applied to the face of the charge block under the punch head in the process of piercing the glasses, on the surface of the shaper pin and on the inner surface of the charging tubes in the process of shaping short smooth hatch by pushing method and the like. Example II. The lubricant in the form of an aqueous solution contains 19% by weight of dry matter with the following composition: 52.7% P2Os, 41.3% Na2O and 6% B2C3. The lubricant solution is a mixture containing by weight: 24.5% H3PO4 - 60% by weight, 9.75% NaOH, 2.75% Na2B407 • 10H2O and 63% H2O. The lubricant in this form is used on the preheated internal surface of the charging pipe sections in the process of shaping the short smooth hatch by the pushing method, on the surfaces of push lava drags in the process of rolling pipes and others. Patent claim Grease for hot plastic working according to the invention is a mixture of phosphorus compounds, sodium and boron, which are subject to dehydration at elevated temperatures, characterized by the fact that in dry matter it contains: 20 to 90% P205, 10 to 75% Na20, maximum 15% P203.
