Diphošo tše di hlolwago ke go ruthetša mo go sa swanelago di ka arolwa ka: 1 Diphošo tšeo di hlolwago ke phetogo ya boemo bja histochemical bja legato la ka ntle leo le hlolwago ke sedirišwa, go swana le oxidation, decarbonization, carburization, sebabole, koporo, bj.bj{{0} ② diphošo tša go se tlwaelege ka sebopego sa ka gare, bjalo ka go se šetše, go thibana ka mo go feteletšego le go se thibele, Kabo ye e sa lekalekanego ya themperetšha ka gare ga billet, kgatelelo ya ka gare (bjalo ka kgatelelo ya themperetšha, kgatelelo ya dinama) e kgolo kudu gomme go phatloga ga billet.
1. Go tloša khapone .
Decarbonization e bolela gore khapone yeo e lego godimo ga legato la godimo ya tšhipi e oxidized ka themperetšha ya godimo, gore diteng tša khapone ya legato la godimo di fokotšege kudu ge di bapetšwa le tiragalo ya ka gare. .
Botebo ba lera decarbonization bo amana le sebopeho sa tšepe, sebopeho sa khase ea sebōpi, mocheso, le nako ea ho kwahela ka mocheso ona. Oxoxixation sepakapaka futhumatsang ho bonolo ho decarbonization, tšepe e phahameng khabone e bonolo ho decarbonization, silicon tšepe e boetse e le bonolo ho decarbonization.
Decarbonization fokotsa matla le mokhathala tshebetso ya dikarolo, 'me ho fokotsa apara ho hanyetsa.
2. Koketšego ya khapone .
Diforomo tše di fišitšwego ka sebjana sa oli gantši di oketšega godimo ga bokagodimo goba karolo ya bokagodimo. ka nako ye nngwe botenya bja legato la khapone bo fihla go 1.5~1.6mm, diteng tša khapone ya legato la khapone di fihla go ka bago 1% (karolwana ya boima), gomme diteng tša khapone tša selegae di bile di feta 2% (karolwana ya boima), gomme dinama tša lystenite di a tšwelela.
Se ke kudu tabeng ya go ruthetša ga sebjana sa oli, ge billet e le kgauswi le nozzle ya sebjana sa oli goba lefelong leo di-nozzle tše pedi di tshelago makhura, ka lebaka la gore oli le moya ga di hlakane gabotse, ka fao go tuka ga se gwa felela, moya wa carburization wo o fokotšago o bopilwe godimo ga bokagodimo bja billet, ka go realo go tšweletša seabe sa khapone ya godimo{0}}
Koketšego ya khapone e dira gore tshepedišo ya go šoma ka motšhene ya Forgings e be mpe, gomme go bonolo go e sega ge o sega{0}}
3. Go fiša kudu .
Go fiša kudu go šupa themperetšha ya go ruthetša ya billet ya tšhipi e godimo kudu, goba ka gare ga tekanyo ya themperetšha ya go foroma le ya kalafo ya phišo, goba go hlatloga ga themperetšha yeo e hlolwago ke khuetšo ya phišo. .
Carbon steel (sub-or over co-analysis steel) often appears after overheating. After martensitic steel overheat, it often appears in the crystal structure, and the mold steel is often characterized by the overheating tissue. After the titanium alloy overheated, the obvious phase crystal boundary and straight slender Wei organization appeared. After overheating of alloy steel fracture will appear stone fracture or strip Fracture. dinama tse nyenyane tse superheated, ka lebaka la boholo bo boholo ba mabele, tla fokotsa thepa mechine, haholo-holo tšusumetso thata.
Ka morago ga kalafo ya phišo ye e tlwaelegilego (go tuka, go tima), mokgatlo wa tšhipi wa sebopego sa go fiša kudu ka kakaretšo o ka kaonafatšwa gomme tshepedišo e bušetšwa . go fiša mo gantši go bitšwa go fiša kudu mo go sa tsepamago; le tebileng overheating ya motsoako sebopeho tšepe ka mor'a hore kakaretso go tuka ga molelo (ho akarelletsa le phahameng mocheso go tuka ga molelo), annealing kapa tima kalafo, le overheating dinama tse nyenyane tse ke ke ka ho feletseng felisoa, ena overheating hangata bitsoa tsitsitseng overheating.
4. Go fiša kudu .
Go fiša ka mo go feteletšego go bolela gore themperetšha ya go ruthetša ya billet ya tšhipi e phagame kudu goba e dula lefelong la go ruthetša themperetšha ya godimo ka nako e telele kudu, oksitšene le kgase e nngwe ya oxidation ka sebjaneng di tsenelela ka gare ga sekgoba magareng ga mabele a tšhipi, gomme oksitšene ka tšhipi, sebabole, khapone, bj.bj., e bopa polasitiki ya mabele, e senya kgokagano ya mabele, go senya kgokagano ya mabele, Tšhipi yeo e nago le go fišwa mo go tseneletšego e tla phatloga ka go otla ka boleta ge e tloša mapetšo a matelele, gomme mapetšo a go selaganya a tla tšwelela ge go fišwa ge go thalwa.
Ga go na mollwane wa themperetšha ye e tiilego magareng ga go fiša kudu le go fiša kudu. Ka kakaretšo, dimelo tša mabele le go qhibidiga go ahlola go fišwa. bakeng sa tšhipi ya khapone, ge mollwane wa mabele le tšhipi ya hlobo ya khemikhale ya oksitšene e šoro (tšepe ya lebelo le legolo, tšhipi ya mohuta wa CR 12, bj.bj{3}) di butšwe ka go qhibidiga ka go qhibidiga, boundary ya mabele e qhibidigago quroteng ya 2} Remelting bolo hlaha ha aluminium motsoako e overburned. forgings ka mor'a ho chesoa, hangata ke ke pholosoa, lokela ho khaolwa.
5. Mapetso a mocheso .
Ha futhumatsang kgolo ingot le kgolo karolo boholo le phahameng motsoako tšepe le phahameng mocheso motsoako billet le fokolang mogote conductivity, haeba ho futhumatsa lebelo le lebelo haholo ka tlaase mocheso sethaleng, billet tla hlahisa khatello e khōlō mogote ka lebaka la phapang e khōlō pakeng tsa ka hare . Ho phaella, billet e na le polasetiki e fokolang ka lebaka la thempereichara e tlase {1} e tla feta boleng ba mogote, 2} e tla feta matsoho a mogote, lefelo le le dikologilego, go dira gore karolo ka moka e be crack.
6. Koporo e hlakileng .
Mapetso a koporo a brittle godimo ga go foroma. Ka go lebelela ga godimo, koporo ye serolane ye bofefo (goba tharollo ye e tiilego ya koporo) e phatlalatšwa go bapa le mollwane wa mabele.
When the billet is heated, such as the residual copper oxide in the furnace, the oxide steel is reduced to free copper at high temperature, and the molten steel atoms expand along the austenite grain boundary, which weakens the connection between the grains. In addition, when the copper content in the steel is higher [>2% (karolwana ya boima)], bjalo ka go ruthetša ka gare ga lefaufau la oxidation, legato leo le humilego ka koporo le bopša ka tlase ga letlalo la tšhipi ya oxide, leo gape le bakago go robega ga tšhipi.
