Tsawg - Kev Siv Dej Thauj: Yam Li Hauv Tsev Neeg Siv Tau Yooj Yim- Lubricating roj kab (tsis muaj kev tawm tswv yim roj);
Tsawg - Siv cov khoom ua si
2.Qhov dab tsi yog cov yam ntxwv tseem ceeb thiab muaj cov xwm txheej ntawm high- cov tshuaj hlau zoo?
Cov yam ntxwv tseem ceeb: Cov ntsiab lus carbon tseem ceeb (10 #: 0.07%-} Cov hlau roj carbon steel (10 #, 20 #) muaj cov roj hmab zoo heev thiab yooj yim ntawm vuam; Nruab Nrab-Carbon Steel (35 #) Muaj lub zog siab dua (45 # Tensile lub zog ntau dua los yog sib npaug nrog kev txiav txim siab thiab kub dua (quenching thiab tempering).
Cov Kev Siv Raug:
Tsawg -} cov roj carbon hlau (10 #, hais txog "kev ua lag luam roj (xav tau khoom siv tsawg dua (thiab tsis yog {5} Tes tsho thiab bushings hauv cov neeg kho tshuab (xav tau kev sib koom tes nrog lwm cov khoom, xav tau qhov ntsuas qhov siab tab sis qis qis). Nruab Nrab Cov Hlau (35 #, 45 #): tsom rau cov khoom siv hluav taws xob (yooj yim.
3.Qhov dab tsi yog cov khoom tseem ceeb thiab cov ntawv teev cov kev siv tsis raug ntawm cov khoom siab siab qis dua hlau?
Cov yam ntxwv tseem ceeb: MN ntxiv (1.2%- 1.}} (tswj hwm kom zoo dua li ntawm 4,66), muaj txiaj ntsig zoo tshaj plaws weldability, thiab siab ntev-ua hauj lwm zoo.
Cov Kev Siv Raug:
Cov qauv tsim vaj tse: xws li cov tshuab crane loj, cov tsev crane, thiab cov khaub ncaws hlau ua kom muaj zog ntxiv kom txo qis zog);
Nruab Nrab - thiab high - cov roj kub uas yuav tsum tau ua rau cov khoom siv hluav taws xob tsawg dua (rau cov tshuab hluav taws xob), thiab lwm yam kev siv hluav taws xob zoo li cov tshuab hluav taws xob (rau lwm yam kev siv hluav taws xob), thiab lwm yam kev siv hluav taws xob), thiab lwm yam kev siv hluav taws xob), thiab lwm yam kev siv tshuab xws li thiab cov khoom siv hluav taws xob loj thiab cov khoom siv hluav taws xob.
4.Qhov dab tsi yog cov ntsiab lus tseem ceeb thiab cov ntawv thov raug ntawm alloy txheej txheem hlau?
Cov khoom tseem ceeb: kev sib ntxiv ntawm CR (nce hardness thiab hnav tsis kam ua kom zoo dua los ntawm kev kho mob tseem ceeb los ntawm kev kho cua sov (carburizing thiab tempering).
20CR: Cov pa roj carbon tsawg, ua rau muaj kev hardness hights (HRC 58-62) thiab cov tseem ceeb ntawm kev carburizing;
40CR: Nruab Nrab Carbon, ua rau muaj lub zog siab (tensile lub zog ntau dua los yog sib npaug ntawm 980 MPa sib npaug tom qab quenching;
42CRMO: Muaj mo, muab cov kev pom kub ua kom zoo thiab nkees ua kom tsis taus, haum rau kev kub thiab cov nra hnyav.
Cov Kev Siv Raug:
20CR: Automotive kis cov khoom kis tau zoo thiab cov kabmob sib tw (yuav tsum tau ua kom pom cov npoo av tsis kam thiab tseem ceeb cuam tshuam);
40CR: Neeg kho tshuab ntxaiv, txhuas cov ntsia hlau, thiab siab}}} kub ua rau lub zog ua kom tsis txhob muaj kev tswj hwm nruj);
20CrMo/42CrMo: High-end equipment components, such as aerospace piping (high-temperature resistance), generator rotor shafts (fatigue resistance), and oil drill pipe (for deep-well high-temperature and high-pressure environments).
5.Qhov twg yog cov khoom tseem ceeb thiab cov ntawv teev cov kev siv ntawm cua sov- tiv taus hlau?
Cov Cuab Yeej Qaum: Ntxiv Cr (1.0%-}}}}}}) thiab mo (0.6%
Cov Kev Siv Cov Kev Siv Hluav Taws Kub Kub, Boiler SuperHeater Leeg, thiab siv tshuaj lom neeg ntev ntev hauv 300℃thiab 500 degree).
