Description
Przedmiotem wynalazku jest zeliwo stopowe aluminiowo-miedziowe na formy szklarskie, zwla¬ szcza na formy do prasowania wyrobów na auto¬ matach, pólautomatach i prasach recznych. Doty¬ chczas na formy szklarskie do wyrobów ze szkla krysztalowego, sodowo-wapniowego, borokrzemo- wego i zaroodpornego uzywano glównie zeliwa sza¬ rego, zeliwa z dodatkiem niklu i chromu, zeliwa sferoidalnego, staliwa stopowego, zaroodpornych stali stopowych oraz stopowe zeliwo miedziowe.Znane zeliwa miedziowe stosowane na formy to zeliwa niskomiedziowe, które zawieraja 0,4 — 2,0 % Cu wagowych, 2,8%-3,6°/o C wagowych, 0,2- 0,7% Cr wagowych, 0,1-0,8% Ni wagowych oraz zelazo, krzem, mangan, fosfor i siarke.Wada dotychczas stosowanych stopów na for¬ my do wyrobów ze szkla jest powstawanie mikro- spekniec powierzchni roboczych podczas formowa¬ nia szkla, a nastepnie pekniec, które odciskaja sie na powierzchni wyrobów szklanych. Mikrospek- niecia i pekniecia powierzchni form powstaja na skutek niskiej odpornosci na szoki temperaturowe.Na powierzchniach roboczych form z wyzej opisa¬ nych stopów powstaje gruba i nietrwala warstwa tlenków, która w temperaturze prasowania reaguje ze skladnikami szkla tworzac miejscowe zabarwie¬ nie wyrobów oraz chropowate powierzchnie wyro¬ bów. Dla uzyskania gladkiej i jednorodnej powie¬ rzchni wyroby te poddaje sie glebokiemu szlifowa¬ lo niu a formy musza byc poddawane czestemu czy¬ szczeniu i regeneracji powierzchni roboczych form.Celem wynalazku jest wprowadzenie do prze¬ myslu szklarskiego form ze stopu na bazie zelaza odpornego na szoki temperaturowe, zmiany obje¬ tosciowe o niskiej rozszerzalnosci cieplnej i wy¬ sokiej przewodnosci cieplnej, odpornego na utle¬ nianie i korozje wynikajacej z wysokich tempera¬ tur dzialania szkla i smarów.Cel ten osiagnieto wytapiajac w piecach elek¬ trycznych i indukcyjnych lub prózniowych stop zeliwa aluminiowo-miedziowego o nastepujacym skladzie w % wagowych: Al Cu Ce Cr C Si Mn P S Fe 0,1—3,0% 1,0—1,5% 0,1—3,0% 0,1—3,0% 2,6—3,0% 0,5—3,0% max—1% max—0,5% max—0,12% reszta PLThe subject of the invention is an aluminum-copper alloy cast iron for glass molds, in particular for molds for pressing products on automatic machines, semi-automatic machines and hand presses. Until now, glass molds for crystal, soda-lime, borosilicate and refractory glass products were mainly made of gray cast iron, cast iron with the addition of nickel and chromium, nodular cast iron, alloy cast steel, heat-resistant alloy steels and alloyed copper cast iron. copper cast iron used for molds are low-copper cast irons, which contain 0.4 - 2.0% Cu by weight, 2.8% -3.6% by weight, 0.2- 0.7% Cr by weight, 0.1 -0.8% Ni by weight and iron, silicon, manganese, phosphorus and sulfur. The disadvantage of the so far used alloys in molds for glass products is the formation of micro-cracks on the working surfaces during glass forming, and then cracks that imprint on the surface of glassware. Micro-cracks and cracks in the surface of the molds are caused by low resistance to temperature shocks. On the working surfaces of the molds made of the alloys described above, a thick and unstable layer of oxides forms, which at the pressing temperature reacts with the glass components, creating a local color of the products and rough surfaces. articles. In order to obtain a smooth and homogeneous surface, these products are subject to deep grinding and the molds must be frequently cleaned and regenerated of the working surfaces of the molds. The aim of the invention is to introduce shock-resistant iron-based molds into the glass industry. temperature, volumetric changes with low thermal expansion and high thermal conductivity, resistant to oxidation and corrosion resulting from the high temperature of glass and lubricants. This goal was achieved by smelting cast iron in electric and induction or vacuum furnaces aluminum-copper with the following composition in% by weight: Al Cu Ce Cr C Si Mn PS Fe 0.1-3.0% 1.0-1.5% 0.1-3.0% 0.1-3.0 % 2.6-3.0% 0.5-3.0% max — 1% max — 0.5% max — 0.12% the rest of PL
