Ha ho tluoa tabeng ea li-castings tsa tšepe tse sa keneleng mocheso, re tlameha ho bua ka indasteri ea phekolo ea mocheso; ha ho tluoa tabeng ea ho phekola mocheso, re tlameha ho bua ka mello e meraro ea indasteri, ho tima, ho tima, le ho futhumatsa. Joale phapang pakeng tsa tse tharo ke efe?
(E 'ngoe). Mefuta ea ho ruruha
1. Annealing ka ho feletseng le isothermal annealing
Annealing e felletseng e boetse e bitsoa recrystallization annealing, eo ka kakaretso e bitsoang annealing. Annealing ena e sebelisoa haholo bakeng sa castings, forgings le profil-rolled profiles of different carbon steels le alloy steels tse nang le compements hypoeutectoid, mme ka linako tse ling e sebelisoa bakeng sa meaho e cheselitsoeng. Hangata e sebelisoa e le phekolo ea ho qetela ea mocheso oa lisebelisoa tse ling tse sa hlokahaleng, kapa e le phekolo ea pele ho mocheso ea lisebelisoa tse ling.
2. spheroidizing annealing
Spheroidizing annealing e sebelisoa haholo-holo bakeng sa tšepe ea hypereutectoid ea carbon le alloy tool tool (joalo ka mefuta ea tšepe e sebelisoang ho etsa lisebelisoa tsa ho seha, lisebelisoa tsa ho lekanya, le hlobo). Morero oa eona o ka sehloohong ke ho fokotsa boima, ho ntlafatsa machinability, le ho itokisetsa ho tima ho latelang.
3. Ho fokotsa khatello ea maikutlo
Ho fokotsa khatello ea maikutlo ho boetse ho bitsoa ho fokotsa mocheso o tlase (kapa mocheso o phahameng oa mocheso). Mofuta ona oa annealing o sebelisoa haholo-holo ho felisa khatello ea kelello e setseng ka li-castings, forgings, welding parts, likarolo tse chesang tse chesang, likarolo tse huloang ka serame, joalo-joalo Haeba likhatello tsena li sa felisoe, li tla etsa hore likarolo tsa tšepe li senyehe kapa li phatlohe ka mor'a nako e itseng kapa nakong ya dithulaganyo tse latelang tsa ho seha.
(Tse peli). Ho tima
Mekhoa e meholo e sebelisoang ho ntlafatsa ho thatafala ke ho futhumatsa, ho boloka mocheso, le ho pholisa ka potlako. Mecha ea ho futhumatsa e sebelisoang haholo ke brine, metsi le oli. The workpiece tima ka metsi a letsoai ho bonolo ho fumana boima bo phahameng le boreleli holim'a metsi, 'me ha e na tšekamelo ea ho matheba a bonolo a sa tingoeng, empa ho bonolo ho baka deformation e tebileng ea workpiece esita le ho phunyeha. Tšebeliso ea oli e le mokhoa oa ho tima e loketse feela ho tima litšepe tse ling tsa alloy kapa lisebelisoa tse nyenyane tsa carbon steel moo botsitso ba supercooled austenite bo batlang bo le boholo.
(Tse tharo). Ho halefisa
1. Fokotsa brittleness le ho felisa kapa ho fokotsa khatello ea kelello ka hare. Ka mor'a ho tima, likarolo tsa tšepe li tla ba le khatello e kholo ea ka hare le brittleness. Haeba li sa halefa ka nako, likarolo tsa tšepe hangata li tla holofala kapa li petsole.
2. Fumana thepa e hlokahalang ea mochine oa workpiece. Ka mor'a ho tima, workpiece e na le boima bo phahameng le brittleness e phahameng. E le ho fihlela litlhoko tse fapaneng tsa ts'ebetso ea li-workpieces tse fapa-fapaneng, ho thatafala ho ka fetoloa ka ho futhumatsa ho loketseng, ho fokotsa brittleness le ho fumana boima bo hlokahalang. Plastiki.
3. Boholo bo tsitsitseng ba workpiece
4. Bakeng sa litšepe tse ling tsa alloy tseo ho leng thata ho li nolofatsa ka annealing, mocheso o phahameng oa mocheso o atisa ho sebelisoa ka mor'a ho tima (kapa ho tloaelehile) ho bokella hantle li-carbides ka tšepe le ho fokotsa boima ba ho nolofatsa ho itšeha.
