DPM150 Flux Cored Hardfacing Vuam Hlau rau Drill Rods
Lus piav qhia luv luv:
DPM150 yog ib txoj hlua khi uas tsim los rau kev hnav zoo heev. Weld hlau qauv yog ntom, hardness yog siab, thiab nws muaj zoo heev hnav tsis kam thiab zoo tawg kuj. Nws yog tsim rau kho cladding los yog tiv thaiv kev ntxiv dag zog ntawm workpieces xws li roj laum kav, thee mine scrapers, thiab breaker hammers.
DPM150 Flux Cored Hardfacing Vuam Hlau:
DPM150 yog tus kheej-shielded flux-cored vuam hlau tsim rau hardfacing laum rods thiab cov khoom raug puas ntsoog loj thiab muaj kev cuam tshuam nyob rau hauv mining, roj av, thiab thee drilling industries. Nws tsim cov qauv martensitic tuab nrog dispersed hard carbides.DPM150 yog ib qho kev ua haujlwm siab flux-cored vuam hlau tshwj xeeb uas tsim los rau hardfacing laum rods thiab cov cuab yeej mining. Nws muaj kev puas tsuaj zoo heev nrog hardness txog HRC 60 thiab zoo dua tawg ua hauj lwm nyob rau hauv ntau txheej vuam. Self-shielded thiab yooj yim rau kev khiav lag luam, DPM150 yog zoo tagnrho rau daim ntawv thov teb yam tsis muaj shielding roj. Haum rau cov khoom siv roj av, thee mining machinery, thiab cov cuab yeej tsim kho uas yuav tsum tau muaj kev tiv thaiv hnav zoo thiab muaj kev cuam tshuam ntev.

Lub ntsiab nta DPM150 Vuam Hlau:
• Tsim nyog thiab txaus hardness (HRC 52–57), zoo heev hnav tsis kam, tsub kom lub laum pas nrig lub neej ntau tshaj 3 zaug;
• Txo kev tawg thiab txo cov nqi kho thiab hloov pauv. Txawm tias thaum hnav txheej yog thinned, lub zog sib txuas nrog lub taub hau laum tseem muaj zog, thiab tsis pom qhov cuam tshuam ntawm hardfacing thiab lub taub hau laum;
• Hlau poob vim kev puas tsuaj ntawm FRW-DPM150 yog tsawg dua 12% ntawm cov khoom hnav-resistant;
• Zoo heev weldability thiab du tsos ntawm weld hlaws;
• Crack-resistant: Tsis pom cov kab nrib pleb tom qab vuam thiab cua txias hauv ib txwm muaj;
• Zoo nkauj arc zoo, du hlaws, thiab me me spatter;
• Muaj peev xwm siv tau rau saum npoo welding ntawm laum rods, laum dab tshos, stabilizers, thiab ntau yam oilfield thiab mining tool nto;
• Tau tshaj nrog ntau yam ntaub ntawv hardfacing.
DPM150 Vuam Hlau Vuam Sau Ntawv:
1.Txhim kho qhov hnav-resistant surfacing cheeb tsam +1 "(25.4mm) dhau ntawm ntug (tshem cov roj, xeb, oxide, thiab lwm yam.) Ua kom muaj kev sib raug zoo ntawm cov txheej txheej saum npoo thiab cov cuab yeej sib koom ua ke yog qhov tseem ceeb rau kev ua haujlwm ntev.
