Kev sib raug zoo ntawm qhov kub thiab txias sib tsoo Media Balls

1. Lub ntsiab lus tseem ceeb ntawm forging thiab dov steel pob yog qhov kub ntawm cov khoom steel

Nyob rau hauv cov txheej txheem ntawm cov khoom steel, qhov kub thiab txias yog qhov tseem ceeb tshaj plaws ntawm kev tswj xyuas qhov zoo. Txawm hais tias nyob rau hauv forging cua sov, isothermal tos, kev kho cua sov, tempering thiab warehouseing tom qab tempering, kub tswj plays lub luag hauj lwm tseem ceeb heev, thiab txawm muaj feem xyuam rau cov metallographic qauv ntawm steel pob. 2. Kev soj ntsuam hauv cov cua sov 1. Cov teeb meem tshwm sim los ntawm kev kub siab heev: oxidation-over-firing, uas ua rau cov txheej txheem sab hauv ntawm lub pob steel yog ntxhib, thiab cov hardness kev ua tau zoo tsis ruaj khov, asymmetrical, thiab tsis sib xws, thiab tseem muaj Lub cev toughness cuam tshuam tus nqi Yog tias nws qis dhau, nws tuaj yeem ncav cuag li 3J / cm2. Siv cov cua sov ntawm cov hlau puag ncig ua piv txwv, cov lus piav qhia hauv qab no tau ua: oxidation tus nqi ntawm cov hlau puag ncig yog qeeb ua ntej 550 ° -600 ° tom qab cua sov, thiab oxidation ceev nce sai thaum nws nce mus txog 700 ° lossis siab dua; Piv txwv tias oxidation ceev ua ntej 900 ° yog 1, 1000 ° yog 2, 1100 degrees yog 3, 1300 degrees yog 7 (raws li qhia hauv qab no) Qhov zoo tshaj plaws kub rau forging: 980 degrees -1080 degrees; Qhov zoo tshaj plaws kub rau dov: 950 degrees -1050 degrees; oxide nplai-hlau tetroxide, trioxide Peb txoj kev tsheb ciav hlau thiab lwm yam. Lus Cim: No. 45 steel yog carbon structural steel, thiab saum B2 yog cov hlau sib xyaw (alloy structural steel). ⑴. Oxide nplai tsis yog tsuas yog tsim nyob rau hauv cov txheej txheem cua sov, tab sis kuj nyob rau hauv cov txheej txheem forging; ⑵. Lub sijhawm cua sov ntev dua, qhov ntsuas oxide ntau dua; ⑶. Kev daws: ceev cua sov thiab txo lub sij hawm cua sov. 2. Qhov teeb meem tshwm sim los ntawm qhov kub thiab txias: Hauv layman' cov ntsiab lus, quenching yog impermeable. Txawm hais tias qhov nyuaj ntawm qhov saum npoo los yog lub hauv paus hardness, HRC tsis tuaj yeem ncav cuag tus nqi ntau yam, uas ua rau lub pob steel tsis hnav tom qab kev ua haujlwm tiag tiag hauv pob zeb (ib feem sib tsoo), txawm tias tawg. 3. Kev cuam tshuam ntawm lub qhov cub cua sov: lub zog hluav taws xob hloov hluav taws xob sib txawv, qhov nruab nrab zaus induction cua sov ceev ceev, tab sis qhov kub tsis zoo, feem ntau hu ua" hard fire". Piv txwv li, cov cua sov ntawm cov hlau sib xyaw zoo li yog nyob ntawm 1000 degrees, tab sis nyob rau hauv qhov tseeb forging, yuav muaj ntau qhov yooj, uas tsis haum rau forging; thiab cov khoom qub zoo li yooj yim tom qab cua sov hauv cov qhov cub hluav taws xob, cov qhov cub hluav taws xob, thiab cov qhov cub roj. Qhov no feem ntau hu ua" mos hluav taws". Cov txheej txheem cua sov ntawm" mos hluav taws" suav nrog cov txheej txheem qeeb xws li preheating thiab kub siab. Thib peb, kev sib raug zoo ntawm qhov kub thiab txias ntawm lub pob zeb 1. Kev khiav hauj lwm ntawm lub zeb yog muab faib ua kev sib tsoo qhuav thiab ntub kev sib tsoo, uas kuj yog ib qho tseem ceeb feature uas distinguishes cam khwb cia steel pob los ntawm forged steel pob. 2. Thaum lub zeb khiav, overhauling los yog hloov lub liner, nws yog tsim nyog los ncuav tawm tag nrho cov steel pob nyob rau hauv lub zeb. Qhov no yuav tsum tau saib xyuas qhov kev hloov pauv ntawm qhov kub ntawm cov khoom steel thaum rov qab sib tsoo, tshwj xeeb tshaj yog cov khoom sib xyaw steel. Yog tias qhov kub ntawm lub pob steel tom qab ua haujlwm tau txo qis (lossis siv ntau txoj kev txhaj tshuaj dej), qhov tev tawm, tev tawm, lossis txawm tias qhov tshwm sim tawg ncaj qha yuav tshwm sim.
