Raws li tus kws tshaj lij hauv kev lag luam steel, kuv feem ntau nug txoghnav resistant steelthiab nws ntau hom. Hauv tsab xov xwm no, kuv yuav muab cov lus qhia dav dav rau nws, tsom rau nws cov khoom, siv, thiab hom zoo tshaj plaws rau cov ntawv thov tshwj xeeb. Thaum kawg ntawm tsab xov xwm no, koj yuav muaj kev nkag siab zoo ntawm nws thiab nws cov ntawv thov.
Hnav-kev nyab xeeb steel, txwv tsis pub hu ua scraped chaw ruaj ntseg steel lossis AR steel, yog ib hom hlau tshwj xeeb tsim los tiv thaiv hnav thiab khawb qhov chaw. Tsim los ntawm alloying Cheebtsam upgrade nws hardness thiab durability, ua rau nws profoundly impervious rau nto coj los ntawm kev sib tsoo, cawv, thiab lwm yam grating powers.
Cov khoom ntawm cov hlau tsis muaj kev nyab xeeb ua rau nws tsim nyog siv rau hauv cov ntawv thov uas muaj kev sib cuag nrog cov ntaub ntawv ntxhib, xws li pob zeb, pob zeb, av, xuab zeb, pob zeb, thiab cov khoom siv niaj hnub no. Nws feem ntau yog siv rau hauv kev lag luam xws li mining, kev loj hlob, quarrying, qhob creation, reusing, thiab kho cov khoom loj.
Cov yam ntxwv tseem ceeb ntawm kev hnav-kev nyab xeeb steel muaj xws li:
Wear-safe steel yog tsim los kom muaj qib siab hardness, feem ntau ua tiav los ntawm kev nthuav dav ntawm cov khoom sib xyaw xws li chromium, manganese, npib tsib xee, thiab boron. Qhov hardness no pab cov hlau nrog kev tawm tsam qhov tsis sib haum xeeb thiab tiv thaiv kev nkag mus ntawm cov ntaub ntawv grating.
Txawm hais tias nws hardness, hnav-kev ruaj ntseg steel tuav tau zoo durability, uas tso cai rau nws tuav lub hwj chim tsis muaj cracking. Qhov kev ruaj khov no ua kom tawg thiab tawg los ntawm kev ua kom zoo, lav cov hlau ua nrog nws txoj kev ntseeg siab nyob rau hauv cov kev ntxhov siab.
Wear-resistant steel feem ntau txawv los ntawm nws qhov tshwj xeeb abrasion tsis kam. Nws hardness thiab lub koom haum muab ib tug tiv thaiv hindrance tiv thaiv kev hnav kev ua si ntawm grating hais, broaden lub neej expectancy ntawm hardware thiab hardware.
Txawm hais tias nws qhov hnyav hnyav, hnav-resistant steel tseem tuaj yeem welded thiab fabricated kom tau raws li cov kev cai tshwj xeeb. Cov txheej txheem vuam tshwj xeeb thiab cov khoom siv tau nquag siv los lav qhov tsim nyog ua ke thiab ua raws li cov khoom siv hlau.
Hlau uas tiv taus hnav yog muaj nyob rau hauv ntau qib thiab thicknesses kom tau raws li qhov yuav tsum tau ntawm ntau yam kev siv. Hnav daim hlau, liners, thoob, txiav ntug, chutes, hoppers, thiab lwm yam khoom uas raug rau abrasive hnav tag nrho yuav ua tau nrog nws.
Dab tsi yog qhov zoo tshaj plaws hlau rau hnav tsis kam?
Cov hlau zoo tshaj plaws rau kev hnav thaiv yog nyob ntawm qhov kev thov tshwj xeeb thiab kev ua haujlwm. Qhov zoo tshaj plaws hom kev hnav zoo steel muaj xws li:
1
Cov hlau uas muaj kev puas tsuaj loj heev hu ua AR400 feem ntau siv hauv kev lag luam mining, quarrying, thiab kev tsim kho. Brinell Hardness Number (BHN) yog nyob ntawm 360 txog 440.
2
Hlau nrog AR500 hardness ntsuam xyuas yog superior rau hlau nrog ib tug AR400 abrasion kuj ntsuam xyuas. Nws feem ntau yog siv rau hauv tub rog, tua mus txog, thiab lub hom phiaj kev lag luam. Nws qhov hardness range yog 470-530 BHN.
3
Chromium Carbide Overlay Steel - Cov hlau no yog tsim los ntawm overlaying txheej ntawm chromium carbide rau saum lub hauv paus hlau zoo li cov hlau maj mam. Nws muaj qhov chaw siab tshaj plaws thiab cuam tshuam kev cuam tshuam thiab yog siv tsis tu ncua hauv cov mining, pob zeb, thiab fais fab ventures.
4
Apparatus Steel - Cov hlau no yog lub npe hu rau nws cov hardness siab thiab hnav thaiv. Nws yog siv tsis tu ncua hauv cov cuab yeej txiav, hla mus, thiab pwm. Nws qhov hardness range yog 60-63 HRC (Rockwell Hardness Scale).
Dab tsi yog qhov hnav tsis kam ntawm cov hlau?
Qhov hnav thaiv ntawm cov hlau yog lub peev xwm ntawm cov hlau los tiv thaiv cov mais uas coj los ntawm lub zog ntxhib lossis xeb. Qhov hnav thaiv ntawm tseem nyob hauv huab cua los ntawm ob peb yam xws li hardness, lub zog, pliability, thiab systesis. Cov hlau uas muaj qib siab ntawm cov khoom siv alloying xws li chromium, npib tsib xee, thiab molybdenum feem ntau yuav muaj kev cuam tshuam ntau dua li cov hlau tsis huv.
Dab tsi Hlau yog Qhov Zoo Tshaj Plaws rau Hnav Tawm Tsam?
Nyob ntawm daim ntawv thov, ntau yam hlau muaj kev hnav tsis kam. Tej zaum cov hlau uas tau pom zoo tshaj plaws siv rau kev hnav thaiv muaj xws li:
Hlau Stainless
Khoom noj khoom haus, chaw kho mob, thiab aviation ventures tag nrho cov txiaj ntsig los ntawm tempered steel qhov kev cuam tshuam zoo dua li hnav thiab yaig.
Titanium
Titanium yog cov hlau nrog ci ntsa iab hnav thiab siv kev thaiv, tsis tshua muaj tuab, thiab lub zog siab. Nws feem ntau siv hauv aerospace, tsheb, thiab kev kho mob kev lag luam.
tungsten carbide
Cov hlau uas paub zoo rau nws qhov siab tawv thiab hnav tsis kam yog tungsten carbide. Nws feem ntau yog siv rau hauv cov cuab yeej txiav, mining, thiab nkag mus rau kev lag luam.
Aluminium Bronze
Cov hlau no muaj kev hnav zoo heev, kev siv khoom zoo heev, thiab lub zog siab. Nws feem ntau yog siv hauv marine, aviation, thiab roj thiab roj ventures.

Hlau uas yog tsim los tiv thaiv hnav thiab puas los ntawm kev sib txhuam thiab lwm yam abrasive rog yog hu uaHnav Resistant Steel Sheet. Daim ntawv thov, kev ua haujlwm, thiab kev siv zog thiab zaus ntawm lub zog abrasive nws yuav ntsib kev txiav txim siab txog yam hnav-resistant steel uas yuav tsum tau.
Lwm cov hlau zoo li stainless hlau, titanium, tungsten carbide, thiab txhuas bronze tuaj yeem muab kev hnav zoo heev, ntxiv rau cov pa roj carbon monoxide. Cov ntaub ntawv no tej zaum yuav raug xaiv rau lawv cov khoom zoo kawg li, xws li kev tiv thaiv kev yaig, lub zog siab, lossis qhov hnyav, txawm tias lawv cov khoom hnav zoo.
Piv txwv li, hardened steel yog nyob rau hauv ntau rooj plaub siv nyob rau hauv daim ntawv thov qhov twg noj tawm tsam yog yooj yim, raws li nws muaj unrivaled kev ruaj ntseg tiv thaiv xeb thiab ntau hom kev yaig. Titanium yog lub teeb yuag hlau uas qhia tau hais tias muaj zog thiab zoo heev tiv thaiv los ntawm hnav thiab noj, mus nrog nws qhov kev txiav txim siab zoo rau kev siv dav hlau thiab tub rog. Tungsten carbide yog cov khoom siv uas tsis tshua muaj zog thiab tsis tshua muaj zog. Nws nquag siv hauv cov cuab yeej txiav thiab cov txheej txheem uas tiv taus hnav. Aluminium bronze muaj kev hnav zoo heev thiab kev tawm tsam, mus nrog nws qhov kev txiav txim siab tsim nyog rau kev siv dej hiav txwv thiab niaj hnub.
