Txawm li cas los xij, thaum koj cov cuab yeej siv cov khoom siv abrasive zoo li crushed iav, clinker, los yog silica xuab zeb nyob rau hauv qhov hnyav zawv zawg, txawm tias 500 HBW steel yuav hnav sai heev.
Rau cov cheeb tsam huab cua no, GNEE Steel muabChromium Carbide Overlay (CCO) Hnav Daim Hlau (tseem hu ua Bimetallic Wear Phaj).
CCO Phaj yog dab tsi?
Hloov ntawm homogenous steel phaj, CCO phaj muaj ob txheej txheej:
Base Phaj:Ib qho me me carbon steel thaub qab (piv txwv li, Q235B lossis ASTM A36) uas nqus cov neeg kho tshuab poob siab thiab tso cai rau kev vuam yooj yim, bolting, thiab tsim.
Hardfaced Overlay:Ib qho kev sib txuam heev ntawm chromium carbides (Cr7C3) welded rau hauv lub phaj phaj. Qhov no overlay ua tau ib tug staggering nto hardness ntawm58-62 HRC (kwv yees . 600-700 HBW).
Kev sib piv ceev: Standard AR Steel vs. CCO Wear Plate
| Feature | Q&T AR Steel (piv txwv li, NM500) | CCO Hnav Plate (Hardfaced) |
| Hom Hnav Zoo Tshaj Plaws | Heavy Impact + Sliding Abrasion | Sliding Abrasion heev (Tsawg / Nruab Nrab cuam tshuam) |
| Nto Hardness | 450 - 550 HWB | 58 - 62 HRC (sib npaug rau 600+ HBW) |
| Hnav Lub Neej | 3x - 5x ntev dua li cov hlau me me | Txog li 5x ntev dua AR500 steel |
| Weldability & Installation | Yuav tsum tau qis -hydrogen ua ntej- cua sov | Yooj yim heev (weld ncaj qha mus rau lub hauv paus me me steel) |
| Tej kev siv | Excavator thoob, pob tseg tsheb txaj | Cement chutes, thee hoppers, tso kiv cua tuaj |
Lus Cim: Qhov pom pom kev tawg ntawm qhov chaw ntawm CCO daim hlau yog qhov tshwm sim ntawm cov txheej txheem hardfacing thiab tsis cuam tshuam rau lub phaj ntawm cov qauv kev ncaj ncees. Qhov tseeb, lawv txo cov kev ntxhov siab hauv vuam.
