Description
Vynález sa týká prostriedku na mazanie pri válcování plechov za studená.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a lubricating agent for cold rolling of sheets.
Valcovanie je tváriniaca operácia, pri ktorej prechodom medzi dvoma valcami je materiál zoslabovaný a získává sa požadovaný prierez. Mění sa nielen tvar materiálu, ale aj jeho vnútorná štruktúra a mechanické vlastnosti. Valcovanie za studená sa uplatňuje u materiálov·, ktoré pre malú hrůbku a rýchle chladnutie nie je možné válcovat za tepla. Slúži k dosiahnutiu malých hrúbok, k zušlachteníu povrchov a zlepšeniu mechanických vlastností plechov. Mazivo pri studenom válcování má dve hlavně úlohy, a to odvod tepla vzniknutého z deformačnej práce a z trenia medzi pracovnými valcami a vývalkom a zmenšovat třecí odpor na najmenšiu hodnotu umožňujúcu však ešte válcovací pochod. Ako mazacie prostriedky sa používajú olejové emulzie, resp. ropné, alebo rastlimné oleje s mazivostnými přísadami.Rolling is a forming operation in which, by passing between the two rolls, the material is weakened and the desired cross-section is obtained. Not only does the shape of the material change, but also its internal structure and mechanical properties. Cold rolling applies to materials that cannot be hot rolled due to their low depth and rapid cooling. It serves to achieve small thicknesses, surface finishes and improve the mechanical properties of sheets. The cold rolling grease has two main tasks, namely the dissipation of the heat generated by the deformation work and the friction between the working rolls and the roll and reducing the frictional resistance to the smallest value, but still allowing the rolling process. Oil emulsions or lubricants are used as lubricants. petroleum or vegetable oils with lubricants.
Bolo nájdené, že je výhodné použit' pri válcování plechov za studená mazivo, ktorého podstata spočívá v tom, že sa skládá z 30 až 45 % hmotnostných řepkového oleja charakterizovaného číslom zmydelnenia 170 až 180 mg KOH/g, jódovým číslom 80 až 90, 36 až 67 % hmotnostných hovadzieho tuku charakterizovaného číslom zmydelnenia 190 až 200 mg KOH/g, jódovým číslom 40 až 50, 3 až 4 % hmotnostně vysokotlakej přísady na báze chlorovaných parafinických uhlovodíkov priemerného zloženia C25H45CI7O charakterizovaného číslom kyslosti do· 0,5 mg KOH/g a obsahom chlóru 40 až 45 %, 0 až 5 % hmotnostných inhibítora korózie imidazolínového typu s výhodou kondenzačného produktu kyseliny olejovej a dietyléntriamínu, 0 až 5 °/o hmotnostných antioxidantu fenolického typu s výhodou 2-6-di-terc.butyl-4-metylfenol a 0 až 5 % hmotnostných antibakterlálnej přísady p-chlorfenolového typu s výhodou etoxylovaného aduktu p-chlórfenolu, pri použití 1 až 1,5 molu etylénoxldu na etoxyláciu.It has been found to be advantageous to use a cold lubricant in the rolling of sheets, which consists of 30 to 45% by weight of rapeseed oil characterized by a saponification value of 170 to 180 mg KOH / g, an iodine number of 80 to 90,36. up to 67% by weight of bovine fat characterized by a saponification value of 190 to 200 mg KOH / g, an iodine number of 40 to 50, 3 to 4% by weight of a high pressure additive based on chlorinated paraffinic hydrocarbons of average C25H45Cl7O a chlorine content of 40 to 45%, 0 to 5% by weight of an imidazoline-type corrosion inhibitor, preferably a oleic acid-diethylenetriamine condensation product, 0 to 5% by weight of a phenolic-type antioxidant, preferably 2-6-di-tert-butyl-4-methylphenol and 0 to 5% by weight of an antibacterial additive of the p-chlorophenol type, preferably an ethoxylated adduct of p-chlorophenol, using 1 to 1.5 moles of ethylene oxide for ethoxylation.
Výhodou jeho použltia je zvýšená mazivostná schopnost, zvýšenie hodinových výkoinov pri válcování, zníženie opotrebovania valcov a zvýšené percento využitia mazadla.The advantages of its use are increased lubricity, increased rolling performance, reduced roll wear and increased lubricant utilization.
Vynález je ďalej objasněný na príkladoch, ktorými však jeho rozsah nie je obmedzený a vyčerpaný.The invention is further illustrated by the following examples, which, however, are not limited and exhaustive.
