Tempered iav rwb thaiv tsev lub teeb transmittance. Cov yam ntxwv yog ruaj khov, thiab ntau hom muaj cov yam ntxwv sib txawv vim qhov sib txawv ntawm qhov chaw siv, thiab kev siv lub ntsiab yog dav heev. Nyob rau hauv kev xaiv ntawm tempered iav, ntxiv rau kev them nyiaj mloog mus rau tus nqi, tab sis kuj nrog nws cov hom thiab cov yam ntxwv muaj ib tug tej yam tuav, ua rau tsis muaj zog, thiaj li yuav nrhiav tau ntau haum rau siv raw cov ntaub ntawv. Peb sau cov ntaub ntawv raw los sau tsab xov xwm, pab koj nkag siab dab tsi raw cov ntaub ntawv ntawm iav fwj tsim abrasives, thiab yuav ua li cas kho cov abrasives rau iav fwj?
Raw khoom ntawm npua hlau rau iav fwj ua abrasives
Txoj kev ua tsis tiav tseem ceeb ntawm iav lub raj mis tsim tuag yog: huab cua oxidation (molting. poob tawm. Me me dub dot). Chamfering thiab deformation. Phosphorous caij nplooj ntoos zeeg yog ib txoj hauv kev tseem ceeb ntawm iav fwj ua tus nqi tuag. Qhov yuav tsum tau ua ua ntej rau kev puas tsuaj rau lub neej kev pab cuam ntawm cov cuab yeej abrasive yog lub tshav kub tsis kam ntawm cov ntaub ntawv raw, uas yog, oxidation tsis kam ntawm raw cov ntaub ntawv ntawm qhov kub thiab txias. Lub peev xwm los tiv thaiv kev loj hlob thiab kev loj hlob yog nyob ntawm qhov yooj yim thiab tom qab calcined roj av coke pom hauv cov ntaub so ntswg.
Ntxiv tooj liab rau npua hlau. Chromium, tin thiab lwm yam khoom tuaj yeem txhawb kev hloov pauv ntawm cov qauv metallographic, txhim kho lub zog compressive ntawm npua hlau, thiab yog li txhim kho chamfering kuj ntawm cov cuab yeej abrasive. Kev muaj peev xwm tiv taus hnav thiab tsim kua muag. Silicon. Txhuas thiab lwm yam khoom, ua rau muaj qhov ntom ntom Si02 thiab A1203 saum npoo huab cua oxide zaj duab xis, yog li txhim kho cov nplaim hluav taws xob muaj peev xwm ntawm cov cuab yeej abrasive.
Tshiab npua hlau raw cov ntaub ntawv rau iav fwj muaj xws li qis-tin npua hlau. Tooj liab chromium npua hlau. Nruab nrab silicon nyias. Nruab nrab silicon molybdenum av. Tsawg tin vermicular hlau. Tsawg aluminium creep hlau, thiab lwm yam. Kev sib piv ntawm kev pab cuam lub neej ntawm iav lub raj mis pwm cov ntaub ntawv: lub neej kev pab cuam ntawm HT200 abrasive cov cuab yeej yog qis dua, thiab qis aluminium creep hlau yog siab dua, thiab qhov kev ncua deb yog li 5 zaug.
Kev saib xyuas ntawm iav fwj abrasives yog ib qho tseem ceeb ua raws li cov kauj ruam hauv qab no
1. Tshem tawm tus neeg saib xyuas de-film hauv pwm. Kub kub cua oxide txheej thiab lwm yam txuas;
2. Qhov raug mob ntawm cov cuab yeej sib tsoo raug kuaj pom;
3. Polish thiab polish qhov teeb meem. Kho;
4. Ua tib zoo saib cov kab thaum kho. Kho ntawm qhov chaw, notches, thiab lwm yam. Kab tsis yog vim arc; Qhov saum npoo tuaj yeem yog ntsug; Lub thais yuav tsum du;
5. Rau polishing thiab polishing tom qab kho, nws raug nquahu kom siv lub tshuab polishing tag nrho. Yog tias cov cuab yeej sib tsoo tsis raug kaw, siv lub pob polishing los txhuam thiab txhuam.
