Muaj Metallographic Microscope rau Cov Yam Ntxim Saib Ntxim Ua ntawm Workpiece thiab Casting Materials!
Cov khoom ntawm cov khoom siv casting, xws li lub zog, toughness, magnetism, corrosiveness, thiab lwm yam khoom siv, lub cev, thiab tshuaj lom neeg, feem ntau yog txiav txim los ntawm lawv cov qauv sab hauv (xws li cov atoms thiab lawv cov kev sib txuas nrog cov atoms nyob sib ze hauv cov lattice, molecules, microstructure, grain shape thiab size, etc.), thiab cov khoom no tau tshwm sim los ntawm kev siv lub luag hauj lwm ntawm lub luag hauj lwm ntawm castings thaum lub sij hawm castings. siab- zog castings, ceev txiav castings, corrosion-resistant castings, tshav kub-resistant castings, hnav-resistant castings, thiab lwm yam). Txhawm rau tsim thiab siv cov castings, nws yog ib qho tsim nyog yuav tsum nkag siab txog lawv cov qauv, thiab cov khoom siv casting yuav tsum tau ua tiav rau lub hom phiaj tshwj xeeb kom ua tau raws li cov qauv tsim ntawm castings. Txhawm rau txhim kho kev ua tau zoo, kev hloov tsim nyog yuav tsum tau ua rau nws lub koom haum sab hauv. Yog tias txoj kev ua haujlwm hloov lub koom haum, cov khoom ntawm cov khoom tseem yuav hloov raws li. Thaum lub sij hawm tsim cov txheej txheem, hloov cov txheej txheem sab hauv ntawm cov casting kuj tseem cuam tshuam rau cov khoom ntawm cov khoom thiab nws cov kev npaj siv. Kev kho cua sov yog ib daim ntawv thov ntawm qhov no.
Raws li cov lus piav qhia saum toj no, lub ntsiab lus ntawm kev kho cua sov rau castings tuaj yeem ua raws li hauv qab no:
Castings tau tswj cov cua sov, tuav, thiab txias cov txheej txheem los hloov cov qauv sab hauv ntawm lawv cov khoom, txhawm rau txhim kho lawv cov khoom siv kho tshuab lossis ua tiav cov hom phiaj tshwj xeeb. Kev sib raug zoo ntawm tus nqi cua sov, tuav qhov kub, tuav lub sij hawm, thiab txias tus nqi ntawm castings tuaj yeem tau los ntawm kev kho cua sov kom ua tiav cov khoom xav tau ntawm castings. Txhua lub sijhawm kho cua sov lub hauv paus muaj xws li plaub qhov kev txiav txim siab hauv qab no:
1, Cua sov tus nqi
2, Xaiv qhov kev kho kub kom tsim nyog
3, Lub sijhawm tuav tswj qhov kub thiab txias
4, Txias tus nqi
