Ukuhlolwa Kwekhwalithi Kokwelashwa Kokushisa Kwamapuleti Omhlathi Wokuhlikihla
Ukuze kuhlolwe ikhwalithi yokwelashwa kokushisa kwamapuleti emihlathi ye-crusher enziwe ngensimbi ephezulu ye-manganese, kufanele kufakwe ukuhlolwa kobulukhuni, imifantu, ukuchezuka kwe-carbide, ukuchezuka kwe-carburization, njll., futhi kumele kwenziwe ngokuhambisana nezidingo zobuchwepheshe. Uma kuneziphambeko ezifana nobunzima obungafaneleki noma ukuchezuka kwe-carbide, ukuchezuka kwesisombululo kanye nokucinywa kwamanzi kumele kwenziwe kabusha, futhi kufanele kuqashelwe ukuqinisekisa ukuthi izinga lokushisa lapho kungena emanzini lihambisana nemithethonqubo.
Kufanele kuqashelwe lapha ukuthi ukuhlukaniswa kwe-carburization kwe-castings kuyingozi: ngemva kokupholisa emanzini, ungqimba olususwe i-carburization luphenduka lube yisakhiwo se-martensite, kodwa ungqimba olungaphezulu lubuthakathaka kakhulu futhi lune-plasticity ephansi kakhulu, futhi amandla alo okubopha nesakhiwo sangaphakathi se-austenite aphansi kakhulu. Ngaphansi kwezimo zokuguguleka okunamandla, ungqimba olungaphezulu luyaxebuka ngokushesha. Ngemva kokupholisa ngamanzi, ungqimba olususwe i-carburization ludlula ekuguqulweni kwe-martensitic, okuholela ekukhuleni komthamo, kuyilapho ungqimba lwangaphakathi lwensimbi luhlala luyisakhiwo se-austenite. Ukucindezeleka kwenzeka phakathi kongqimba olungaphezulu nongqimba olungaphakathi, futhi amazinga okuncipha okuqondile kwezakhiwo ezimbili nawo ahlukile ngesikhathi sokupholisa okulandelayo, okuholela ekuqhekekeni kobuso.
