SA516 Gr60 Gr70 SA387Gr22CL2 Thawv Phaj
Kev xa khoom raws li txoj cai
quenching: tom qab cua sov mus rau theem hloov qhov kub thiab txias saum toj no, cov txheej txheem txias txias.Ua kom lub hardness ntawm cov khoom, tab sis txo cov toughness.
Cov cua sov li qub: tom qab cua sov mus rau saum cov theem hloov kub, txias ib txwm (hauv huab cua).
Annealing: tom qab cua sov mus rau saum toj ntawm theem hloov pauv kub, ces maj mam txias.Tshem tawm cov nyhuv quenching, tshem tawm cov kev ntxhov siab, thiab tshem tawm cov kev sib xyaw ua ke.
Refire: tom qab quenching, ces kub rau ib tug tej yam kub thiab txias (hauv qab lub quenching kub), txuag tshav kub, thiab ces txias.Uniform muaj pes tsawg leeg, me ntsis txo cov hardness, zoo heev txhim kho lub toughness.
Nws yog dav siv nyob rau hauv roj av, tshuaj lom neeg kev lag luam, chaw nres tsheb fais fab, boiler thiab lwm yam lag luam, rau zus tau tej cov reactor, tshav kub exchanger, separator, spherical tank, roj thiab roj tank, liquefied gas tank, nuclear reactor siab plhaub, boiler nruas, liquefied roj thiab roj lub tog raj kheej, hydropower chaw nres tsheb siab siab dej yeeb nkab, turbine volute thiab lwm yam khoom siv thiab cov khoom siv.
Control dov kuj yog tswj dov
Los ntawm kev kho cov tshuaj muaj pes tsawg leeg ntawm cov hlau, los ntawm kev tswj cov cua kub kub, dov kub, deformation system thiab lwm yam txheej txheem tsis, los ntawm kev tswj cov kev hloov txoj cai ntawm austenite lub koom haum thiab cov ntaub so ntswg daim ntawv ntawm theem hloov khoom, thiaj li mus cuag lub hom phiaj. ntawm refining lub koom haum thiab txhim kho lub zog thiab toughness.
Tswj dov tsis tu ncua ignition yog tswj dov, dov kub, siab ntim, txias ceev, raws li zoo raws li qhov kawg dov kub thiab lwm yam kev ntsuas, thiaj li hais tias cov kev ua tau zoo ntawm cov hlau phaj mus cuag ib tug zoo piv ntawm lub zog thiab toughness.
Qhov hluav taws kub zoo, tseem hu ua normalization, yog txheej txheem kev kho cua sov hlau kom sov cov khoom ua haujlwm rau Ac 3 lossis Accm saum toj 30 ~ 50 ℃, txuag hluav taws xob rau ib lub sijhawm, tshem tawm ntawm qhov cub hauv huab cua lossis dej tsuag, tshuaj tsuag lossis cua txias.Qhov txawv ntawm qhov hluav taws kub ib txwm thiab annealing yog tias qhov hluav taws kub ib txwm txias ceev yog me ntsis sai dua qhov annealing txias ceev, yog li cov ntaub ntawv hluav taws kub ib txwm yog nyias dua li cov ntaub so ntswg annealing, thiab nws cov khoom siv kho mob kuj tseem txhim kho.Tsis tas li ntawd, qhov cua txias sab nraum lub qhov cub tsis nyob hauv cov khoom siv, cov khoom tsim tau siab, yog li cov khoom siv los hloov annealing kom deb li deb tau.
Daim ntawv thov tseem ceeb ntawm qhov hluav taws kub yog: ① rau cov pa roj carbon tsawg, qhov hluav taws kub tom qab lub hardness yog me ntsis siab dua annealing, toughness kuj zoo, yuav siv tau raws li kev txiav ua pretreatment.② Siv nyob rau hauv nruab nrab carbon steel, yuav hloov tau los ntawm Kev kho kom zoo raws li kev kho cua sov zaum kawg, kuj tuaj yeem siv los ua kev npaj ua ntej quenching los ntawm induction cua sov txoj kev. Raws li kom tau txais lub koom haum zoo uas xav tau rau kev sib tw ua kom zoo nkauj. quenching.⑥ Rau cov hlau cam khwb cia hlau, kom lub hardness, lub zog, hnav tsis kam, xws li kev tsim cov tsheb, tsheb laij teb, diesel cav crankshaft, txuas pas nrig thiab lwm yam tseem ceeb.⑦ Tag nrho cov kev ntsuam xyuas steel qhov muag teev ua ntej qhov zoo ignition, tuaj yeem tshem tawm lub network thib ob carburization, kom ntseeg tau tias tag nrho cov carburization annealing.
