245024 8 PŘEDMĚT VYNÁLEZU Způsob patentování ocelového drátu, při nimž se svitek drátu podrobuje austenitizaciv ohřívací peci, ponořuje se do solné lázné a potom do vodní lázně, vyznačující se tím,že svitek drátu z oceli o hmotnostním obsahu uhlíku od 0,30 do 1,00 % v rozsahu průměrůod 3,0 do 30 mm se umístí do pece, vyhřáté na teplotu převyěující nejméně o 100 K teplo»tu austenitizace a jakmile drát dosáhne teploty o 40 až 100 K vyěSlznež je teplota přemě»ny oceli, ohřev pece se přeruší nebo prudce sníží a udržuje se maximálně po dobu šestiminut, načež se drát ponoří do solné lázně, o teplotě 430 až 460 °C s výdrží v solnélázni maximálně 3 minuty, a nejdéle za 1,5 minuty se ponoří na nejméně 2 minuty do vodnílázně. Uznáno vynálezem na základě výsledků expertizy, provedené Úřadem pro vynálezectví apatentnictví, Berlín, DO. Severografia, n. p., MOST Cena 2,40 KčaOBJECT OF THE INVENTION The method of patenting a steel wire in which a wire coil is subjected to an austenitizing heating furnace is immersed in a salt bath and then into a water bath, characterized in that a wire coil of steel having a carbon content of from 0.30 to 1, 00% in the range of diameters from 3.0 to 30 mm are placed in a furnace heated to a temperature of at least 100 K of heat and austenitization, and as soon as the wire reaches a temperature of 40 to 100 K, the temperature of the steel is discontinued or steeply lowered and held for a maximum of six minutes, whereupon the wire is immersed in a salt bath, at a temperature of 430 to 460 ° C, with a sunshine duration of no more than 3 minutes, and immersed in a water slide for at least 2 minutes within 1.5 minutes. Recognized by the invention on the basis of the results of the expert review by the Office for Inventory Apatent, Berlin, DO. Severografia, n. P., MOST Price 2.40 CZK
