Qhov sib txawv ntawm kev xaiv cov ntaub ntawv yob rau cov yob yob thiab cov kab kub dov

Hauv kev lag luam steel dov, cov yob siv rau hauv cov dov txias thiab kub dov kab yog qhov tseem ceeb ntawm cov khoom tseem ceeb. Vim muaj cov txheej txheem sib txawv thiab kev siv ib puag ncig ntawm ob, kuj tseem muaj qhov sib txawv tseem ceeb hauv kev xaiv cov khoom ntawm cov yob. Peb yuav tshawb xyuas kom meej qhov sib txawv ntawm cov khoom xaiv ntawm cov yob siv hauv cov yob yob thiab cov kab kub dov.

Ua ntej, muaj qhov sib txawv tseem ceeb hauv kev ua haujlwm kub ntawm cov kab txias dov yob thiab cov kub dov kab yob. Kub dov kab yog nqa tawm ntawm qhov kub thiab txias thiab feem ntau yuav tsum tau tiv taus qhov kub thiab txias li 1200 ℃. Yog li ntawd, cov ntaub ntawv yob ntawm cov kab kub dov yuav tsum muaj kev ua tau zoo ntawm qhov kub thiab txias thiab thermal qaug zog. Cov ntaub ntawv muaj xws li high chromium cam khwb cia hlau, high-speed steel, thiab cov hlau tsis muaj cua sov. Cov ntaub ntawv no tsis tsuas yog tuav lub zog thiab hardness ntawm qhov kub thiab txias, tab sis kuj tiv thaiv oxidation thiab kub corrosion, yog li txuas ntxiv lub neej kev pab cuam ntawm yob.

Ntawm qhov tsis sib xws, cov kab txias dov yog nqa tawm ntawm lossis ze ntawm chav tsev kub, yog li cov yob tsis tas yuav tiv taus qhov kub thiab txias. Txawm li cas los xij, thaum lub sij hawm txias dov txheej txheem, vim yog qhov kev xav tau siab rau qhov zoo ntawm cov ntawv hlau, qhov tawv tawv thiab hnav tsis kam ntawm cov yob yog qhov tseem ceeb tshwj xeeb. Cov kab txias dov yob feem ntau yog ua los ntawm cov khoom siv xws li cov cuab yeej hlau, cov cuab yeej carbon steel, lossis chrome plated steel. Cov ntaub ntawv no muaj cov hardness siab thiab hnav tsis kam, uas tuaj yeem ua kom ntseeg tau tias lub ntsej muag ntawm cov yob tsis yooj yim hnav thaum lub sijhawm siv lub zog ntev, yog li ua kom cov khoom zoo ntawm cov khoom.

Qhov thib ob, qhov kev thauj khoom thiab siab ntawm cov yob ntawm cov dov txias thiab kub dov kab kuj txawv. Cov kab kub dov yuav tsum tau ua kom kub kub steel billets rau hauv ntau yam tshwj xeeb ntawm cov hlau phaj, thiab cov yob yuav tsum tau tiv taus siab thiab cuam tshuam, yog li cov khoom yuav tsum muaj lub zog siab thiab zoo toughness. Cov kab txias dov, vim yog nqa tawm ntawm qhov kub qis, feem ntau dais siab dua shear thiab kev sib txhuam quab yuam ntawm cov yob. Yog li ntawd, kev xaiv cov khoom ntawm txias dov yob tsom ntau rau lawv cov hnav tsis kam thiab qaug zog.

Tsis tas li ntawd, cov txheej txheem ntawm cov txheej txheem txias dov kab yob feem ntau muaj cov txheej txheem kho saum npoo, xws li chrome plating, quenching, thiab lwm yam, txhawm rau txhim kho lawv cov tawv tawv thiab hnav tsis kam. Txawm li cas los xij, vim kev ua haujlwm nyob rau hauv qhov kub thiab txias, cov txheej txheem kev kho saum npoo no tsis haum rau cov kab kub dov. Hloov chaw, lawv cov kev ua tau zoo yog txhim kho los ntawm cov hlau alloy thiab cov txheej txheem kho cua sov ntawm cov khoom nws tus kheej.

In summary, there are significant differences in the material selection of rolls for cold rolling and hot rolling lines, mainly reflected in the different requirements for working temperature, load, pressure, and surface quality. Hot rolling line roll materials need to have excellent high-temperature performance and thermal fatigue resistance, while cold rolling line roll materials emphasize high hardness and high wear resistance. Understanding and correctly selecting suitable roll materials is of great significance for ensuring the stability of the rolling process and product quality.
