Dab tsi yog cov khoom siv feem ntau siv rau Rolling Mill Rolls

I. Cov ntaub ntawv yob.

 

1. Cam khwb cia hlau.

Cam khwb cia hlau yog ib qho ntawm cov khoom siv dav siv ntau tshaj plaws. Common cam khwb cia hlau muaj xws li grey cam khwb cia hlau, ductile hlau, thiab dawb cam khwb cia hlau.Cam khwb cia hlau yobyog dav siv nyob rau hauv me me thiab nruab nrab rolling nroj tsuag vim lawv tsis tshua muaj nqi tsim, yooj yim ua thiab kho, thiab zoo hnav tsis kam.

 

2.Bimetallic composite dov zeb yob.

Lub bimetallic composite yob yog tsim los ntawm ob yam hlau sib txawv. Cov txheej txheej sab nrauv feem ntau yog siv cov hlau alloy nrog zoo hnav tsis kam, thaum txheej sab hauv siv pheej yig carbon steel. Qhov txiaj ntsig tseem ceeb ntawm cov khoom siv no yog tsim los ntawm cov khoom sib txawv, uas tuaj yeem sib npaug ntawm qhov tawv tawv thiab sab hauv toughness, ua rau cov dov zeb tsis tshua muaj kev puas tsuaj thiab qaug zog tom qab siv mus ntev.

 

3. qhwv roj hmab yob.

Qhwv roj hmab yob yog ib txheej ntawm roj hmab nrog zoo hnav tsis kam thiab hardness uas yog them rau saum npoo ntawm yob kom hnav tsis kam thiab plam tsis kam. Cov khoom no yog tshwj xeeb tshaj yog haum rau high-speed dov ntawm lub teeb yuag hlau.

 

4.High ceev steel thiab nyuaj alloy.

Cov ntaub ntawv no feem ntau yog siv los tsim cov high-precision, high-speed, thiab high-strength yob. Lawv muaj cov hardness siab heev thiab hnav tsis kam, thiab dov nyob rau hauv huab cua txias tuaj yeem ua kom muaj txiaj ntsig thiab zoo.

 

 

II.Qhov zoo thiab qhov tsis zoo ntawm cov khoom sib txawv.

 

1. Cam khwb cia hlau.

Qhov zoo: Cov nqi tsim khoom tsawg, ua haujlwm yooj yim, thiab hnav tsis kam.

Disadvantages: Kev qaug zog tsis zoo thiab kev ua haujlwm tsis zoo ntawm cov cua sov.

 

2.Bimetallic composite dov zeb yob.

Qhov zoo: Nws tuaj yeem sib npaug ntawm qhov tawv tawv thiab sab hauv toughness, thiab tsis tshua muaj kev qaug zog thiab tawg tom qab siv mus ntev.

Disadvantage: High manufacturing nqi.

 

3. qhwv roj hmab yob.

Qhov zoo: Nws ua rau kom hnav tsis kam thiab plam tsis kam, tshwj xeeb tshaj yog tsim rau kev kub ceev hlau dov.

Disadvantage: Kev pab cuam lub neej tsawg, tsis haum rau lub zog siab thiab siab siab dov.

 

4.High ceev steel thiab nyuaj alloy.

Qhov zoo: Tsis tshua muaj siab hardness thiab hnav tsis kam, haum rau high-precision, high-speed, thiab high-strength dov.

Disadvantages: High manufacturing nqi thiab susceptibility rau thermal cracking.

 

Cov ntsiab lus:

Zuag qhia tag nrho, kev xaiv ntawm cov khoom siv yob yuav tsum sib npaug raws li cov kev xav tau tshwj xeeb dov thiab cov nqi tsim khoom. Cov khoom sib txawv muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab yuav tsum tau xaiv raws li qhov xav tau.
