Sovershenstvovanie Goryachey Prokatki Nizkolegirovannoy Stali 12+

📙 Vysokotemperaturnaya gazovaya korroziya, imeyushchaya mesto pri nagreve slyabov v pechnoy atmosfere, soderzhashchey kislorod, pered goryachey prokatkoy ukhudshaet pokazateli proizvodstva listov. Okalinoobrazovanie privodit k poteryam metalla, uvelichivaet razmery poverkhnostnykh defektov liteynogo proiskhozhdeniya, soprovozhdaetsya obezuglerozhivaniem i gazonasyshcheniem, ukhudshaet kachestvo poverkhnosti. Nalichie tolstogo sloya vkatannoy okaliny uvelichivaet trudozatraty pri zachistke gotovogo prokata i snizhaet ego kachestvo. Poetomu razrabotka effektivnykh metodov snizheniya poter' metalla i povysheniya kachestva poverkhnosti goryachekatanykh listov yavlyaetsya aktual'nym. V rabote dannaya problema reshaetsya putem naneseniya alyuminievogo gazotermicheskogo pokrytiya na shirokie grani slyabov pered nagrevom pod prokatku. Na primere nizkolegirovannykh staley trubnogo sortamenta pokazano, chto nanesenie alyuminievogo pokrytiya v vide polos vdol' kromok na shirokikh i uzkikh granyakh slyabov privodit k vyravnivaniyu mekhanicheskikh svoystv po dline listov i otsutstviyu treshchin na bokovykh kromkakh. Kniga prednaznachena dlya inzhenerno-tekhnicheskogo personala metallurgicheskikh predpriyatiy, a takzhe studentov VUZov mashinostroitel'nykh i metallurgicheskikh spetsial'nostey.
