Vim li cas hnav-resistant steel offectricion kev xaiv rau cov mining steel hoppers thiab chetts?

Tsis zoo siv

Hlau qauv hauv kev txiav

 

Nrog rau kev pom zoo thoob ntiaj teb nyob rau ib puag ncig thiab kev cog qoob loo rau kev coj ua mining kom ruaj khov thiab mining kev lag luam thiab mining kev lag luam tau raug teeb tsa txoj kev hloov pauv.

 

Cov qauv hlau, nto moo rau lawv cov khoom siv siab tshaj, muaj kev cuam tshuam tseem ceeb, muaj kev hloov pauv ntawm cov khoom siv ntawm lub pob zeb. Los ntawm Headframes thiab conveyor tshuab rau hoppers thiab chutes hnyav ua lub ntsej muag rau lub luag haujlwm IRREplacing lub luag haujlwm rau kev txhim kho kev ua haujlwm thiab kev nyab xeeb.

Hnav-resistant steel nyob rau hauv tsuas

 

Raws li SSAB, kev siv ntawm kev hnav-resistant steel plates zoo li Hardox 450 nyob rau hauv Mining Hoppers tuaj yeem txuas ntxiv cov phiaj hlau, nrog cov nqi txij nkawm txo los ntawm 40%.

 

Hauv kev tsim cov khoom siv ntawm cov khoom siv tseem ceeb xws li cov plos thiab chetting, kev siv lub zog loj (hsla) cov nqi txuas ntxiv. Yog li, dab tsi tshwj xeeb lub luag hauj lwm cov hnav-resistant steel daim hlau ua si hauv cov khoom siv tsuas yog? Kab lus no aims los muab cov lus qhia ntxaws ntxaws.

1. Cov kev coj zoo dua

Puas Txhob Ua Ntej Tawm Tsam Cov Ntaub Ntawv

 

Lub luag haujlwm tseem ceeb ntawm lub mine howper thiab chute yog kom thauj khoom thiab thauj cov khoom nyuaj, xws li hlau}. 5), thiab granite ({4 4}}). Cov ntaub ntawv no yuav tsim kev sib tw thiab kev cuam tshuam thaum lub sijhawm thauj mus los, ua rau muaj kev hnav hnyav rau sab hauv phab ntsa ntawm phab ntsa mining. Hnav cov hlau tiv thaiv steel plates tau zoo nrog cov teeb meem no nrog lawv cov yam ntxwv nyuaj. Piv txwv li, Hardox 450 muaj lub hardness ntawm 450 HBW (brinell hardness), uas txhim kho nws cov phiaj loj (hardness of {} hbw). HARDOX 450 Hlau tuaj yeem txo tus nqi sab hauv rau 1/3 ntawm cov hlau hlau hauv cov phiaj xwm hluav taws xob ib puag ncig.

Kev Cuam Tshuam thiab Yaig Kuj

 

Dawb-poob chaw thau khoom ntawm {{1} tox ore batches tsim cov txiaj ntsig ntau dua 15 m / s, ua rau cov neeg tsav tsheb uas tab tom ua rau Eposive hnav cov nqi ntawm cov hlau. Yog li, siab tawv thiab loj cov khoom siv xws li ore thiab thee yuav muaj kev cuam tshuam vim qhov siab txawv thaum poob, uas ua rau yaig hnav. Tus Australian Mine saws coj tus neeg tiv taus steel phaj, uas txo cov zaus ntawm kev yaig kev puas tsuaj rau sab hauv phab ntsa ntawm lub chute los ntawm 60%.

2. Kev Cuam Tshuam Launchance

Puas-tiv taus cov pob zeb hluav taws xob ua ke nrog hardness nrog kev nruj me ntsis, ua kom lawv nqus tau thiab dissipate poob siab los yog thee chunks.

Cov yam ntxwv no yog qhov tshwj xeeb tshaj yog hauv kev xyaum. Piv txwv li, hauv Qhib-Pit cov xaim hluav taws xob, kev thauj khoom ntawm cov hlau loj tuaj yeem ua rau muaj kev cuam tshuam nrog cov hlau loj tuaj yeem ua rau muaj zog thiab tswj hwm cov cuab yeej siv.

3. Txuas ntxiv kev pabcuam lub neej rau cov khoom siv mining.​​​​​​​​​​​​​​​​​​​​​​​​​​​​ 

(1) txo qis qis

Los ntawm kev pheej hmoo ntawm kev pheej hmoo ntawm Chute thiab Hopper kev puas tsuaj, hnav-resistant steel daim hlau ua kom muaj kev ua haujlwm txuas ntxiv, txo tus nqi ua kom muaj peev xwm ua kom muaj txiaj ntsig zoo rau kev saib xyuas.

(2) Cov nqi kho qis dua

Thaum kev tshuaj xyuas ib ntus, hnav cov hnab hluav taws xob tsis kam ua kom zoo dua qub-zog hlau los ntawm kev tu cov kev tu. Qhov no txo ​​kev ua haujlwm, kev hloov cov khoom siv, thiab cov nqi ua haujlwm thiab cov nqi ua haujlwm dhau ntawm cov cuab yeej ua haujlwm.

Kev sib piv ntawm cov khoom ntawm cov ris-resistant steel thiab high-zog steel phaj

4.enhanced khoom zoo thiab txaus sib xws

Thaum cov phab ntsa sab hauv ntawm cov hoppers thiab chutes kev coj ua, hlau immer yog tsim, paug cov ntaub ntawv thiab cuam tshuam lawv txoj kev coj dawb huv thiab kev ua kom zoo. Hnav-resistant steel daim phiaj chaw ua haujlwm no los ntawm kev tswj hwm cov qauv txheej txheem ntawm sab hauv phab ntsa thiab ua kom muaj cov khoom siv zoo nkauj heev. Piv txwv li, hauv kev lag luam metallurgical, txoj kev huv huv ntawm cov hlau ore yog qhov tseem ceeb rau qhov zoo ntawm downstream steel lawm. Kev siv ntawm kev hnav cov phiaj hlau tiv thaiv tau zoo tswj cov qib impurity rau hauv qab {2}, lub rooj sib tham txoj hlua tswj kev lag luam.

Tsis tas li ntawd, hnav cov hlau tiv thaiv-resistant pab khaws tseg qhov ruaj khov ntawm cov khoom siv, uas yog qhov tseem ceeb rau kev tswj cov khoom zoo sib xws. Hauv cov ntawv thov xws li cov kev thauj cov thee, kev khiav tawm ncaj qha cuam tshuam nrog kev ua kom dav dav thiab kev tswj hwm kev ua haujlwm dav dav ntawm cov khoom siv no.
