Product Overview
Lub Cr26 High Chromium Cast Iron Boiler Grate Bar yog ib qho hnav-cov khoom tiv thaiv kev tiv thaiv tshwj xeeb tsim los rau kev xav tau kev ua haujlwm thermal ua ib puag ncig uas cov pa grate bar yuav ua tsis tiav ntxov. Nrog rau cov ntsiab lus chromium tswj tau meej ntawm 23% thiab 28%, qhov siab chromium dawb cam khwb cia hlau muab tshwj xeeb tsis kam rau siab -kub oxidation, abrasive hnav, thiab thermal qaug zog.
Cr26 siab chromium cam khwb cia hlau belongs rau lub siab chromium dawb hlau tsev neeg, dav lees paub tias yog cov khoom siv zoo tshaj plaws rau kev hnav tsis kam ntawm qhov kub siab. Tsis zoo li cov tsoos Ni-Hard lossis Ni- tawm tsam cov alloys uas vam khom ntau ntawm npib tsib xee, Cr26 ua tiav nws qhov kev ua tau zoo los ntawm kev sib faib ntom ntom ntawm M7C3- hom chromium carbides, muab piv rau - lossis txawm tias zoo dua hnav tsis kam ntawm tus nqi qis dua.
Cov grate bar no yog tsim los siv rau hauv cov saw grate boilers, reciprocating grate incinerators, sintering pallet tsheb, thiab industrial furnaces -cov ntaub ntawv uas grate tuav yuav tsum tiv taus kub kub thiab corrosive flue gases. Kev sib xyaw ua ke ntawm martensitic matrix thiab hard chromium carbides kom ntseeg tau tias Cr26 grate tuav tuav qhov ruaj khov thiab thauj khoom -cov kabmob muaj peev xwm txawm tias nyob rau hauv cov haujlwm hnyav tshaj plaws.
- Chain grate boiler grate tuav
- Sintering rauv grate tuav rau pallet tsheb
- Mechanical grate incinerators (kab rov tav & inclined reciprocating systems)

Kev kho cua sov kom zoo yog qhov tseem ceeb rau kev qhib lub peev xwm ntawm Cr26 siab chromium cam khwb cia hlau. Cov kev tshawb fawb tau pom tias qhov kev kho cua sov zoo tshaj plaws yog 2 teev ntawm quenching kev kho mob ntawm 1000 degree, tom qab ntawd tempering tom qab ntawm 400 degree. Lub hardness ntawm Cr26 HCCI yog ncaj qha cuam tshuam rau nag lossis daus thiab redissolution ntawm theem nrab carbides thaum lub sij hawm kho cua sov txheej txheem.
Peb cov txheej txheem tsim khoom ua raws li ob -theem kev kho cua sov raws tu qauv:
- Softening kho ntawm 950℃rau 10 teev
- Hardening kev kho mob ntawm huab cua quenching ntawm 1000 degree, nrog tempering ntawm 460℃rau kev pom kev ua tau zoo
Tempering nyob rau hauv qis kub ntau yam (200-300 degree) tempers lub martensite tau thaum lub sij hawm quenching, li no txo rhiab heev rhiab heev thiab txhim kho kev poob siab.
Kev Ua Haujlwm Zoo
Siab -Tub kub Oxidation Resistance
Grate bar nyob rau hauv boilers thiab incinerators ua hauj lwm rau ncua sij hawm nyob rau hauv hnyav ib puag ncig yam ntxwv ntawm kub kub, oxidizing atmospheres, thiab corrosive flue gases. Cov ntsiab lus chromium siab ntawm Cr26 grate tuav txhawb kev tsim cov txheej txheem chromium oxide ruaj khov rau ntawm qhov chaw, uas ua raws li kev tiv thaiv kev tiv thaiv oxidation. Qhov no tus kheej -kho oxide txheej ua rau Cr26 grate tuav kom ua tiav lub neej ua haujlwm ntev dua piv rau cov tsoos cam khwb cia hlau lossis qis- alloy steel grate tuav.
01
Superior Abrasion Wear Resistance
Kev sib xyaw ua ke ntawm ib qho nyuaj martensitic matrix thiab M7C3 chromium carbides muab qhov tshwj xeeb tiv thaiv rau kev hnav los ntawm cov tshauv, slag, thiab cov khoom siv roj hla dhau qhov grate nto. Hnav tsis kam nyob ntawm ob qho tib si hardness thiab toughness ntawm matrix - ob lub zog uas peb cov txheej txheem kho cua sov ua kom zoo tshaj plaws.
02
Zoo heev Thermal Fatigue Resistance
Thaum lub sij hawm boiler pib- nce, kaw, lossis thauj khoom hloov pauv, grate tuav tau rov ua dua thermal cycling. Cov thermal stresses tsim los ntawm cov voj voog no tuaj yeem ua rau tawg hauv cov khoom tsis zoo. Piv nrog rau lwm cov ntaub ntawv, Cr26 siab chromium cam khwb cia hlau nthuav tawm qis dua rau siab - kub embrittlement thiab zoo thermal qaug zog tiv thaiv, txo qhov kev pheej hmoo ntawm kev ua tsis tiav.
03
Corrosion Resistance nyob rau hauv Aggressive Environments
Muaj boilers thiab incinerators feem ntau hlawv roj uas tsim acidic combustion gases. Chromium imparts corrosion kuj rau cam khwb cia hlau, ua Cr26 tshwj xeeb resistant rau oxidizing ib puag ncig thiab tsis muaj zog acids. Qhov kev tiv thaiv corrosion no pab tiv thaiv qhov txo qis hauv kev pabcuam lub neej uas tshwm sim thaum oxidation thiab abrasion ua synergistically.
04
Tus nqi -Txoj kev xaiv zoo rau Nickel-Raws li Alloys
Cr26 siab chromium cam khwb cia hlau ua tiav kev ua tau zoo piv rau - lossis txawm tias zoo dua li - tsoos Ni-Hard thiab Ni- tawm tsam alloys ntawm tus nqi qis dua. Los ntawm kev siv chromium ntau dua li cov npib tsib xee uas kim tshaj li qhov tseem ceeb alloying, Cr26 grate bars xa cov nqi zoo tshaj -kev ua tau zoo yam tsis muaj kev cuam tshuam kev hnav tsis kam lossis siab - kev ua haujlwm kub.
