Raws li cov khoom siv kho dua tshiab rau crushing siab - cov ntaub ntawv hardness, Super Wear-Resistant Steel series crusher rauj tshaj li cov tsoos siab -manganese steel thiab alloy pas nrig series hauv kev ua tau zoo los ntawm kev ua tiav hauv ob qho tib si tsim thiab txheej txheem thev naus laus zis. Lawv cov txiaj ntsig tseem ceeb tuaj yeem suav nrog hauv tsib qhov hauv qab no:
I. Wear Resistance thiab Service Life: Ib kauj ruam-Los ntawm-Txoj Kev Txhim Kho
Super hnav-cov hlau tsis muaj zog siv cov qauv sib xyaw ntawm "qis-carbon, siab-chromium alloy + nano-carbide dispersion ntxiv zog" kom ua tiav microhardness ntawm HRC 60-65 (piv rau HRC 45-1} rodese steel). The surface forms a dense, wear-resistant hard phase, effectively resisting material impact and cutting wear. Raws li tib yam kev khiav hauj lwm (xws li crushing granite, basalt, thiab lwm yam ntaub ntawv nrog ib tug Mohs hardness ntawm 7 los yog siab dua), nws hnav tsis kam yog txhim kho los ntawm 50% -80% piv rau high-manganese hlau ntxiv rau alloy pas nrig series. Qhov no tseem txuas ntxiv kev pab cuam lub neej, txo qhov zaus ntawm kev hloov rauj taub hau. Piv txwv li, ntawm cov kab ntau lawm crushing 500 tons ntawm ore ib hnub twg, tsoos rauj taub hau yuav tsum tau hloov txhua txhua 1-2 lub hlis, thaum super-coj-resistant steel rauj taub hau tuaj yeem ncua qhov no mus rau 3-4 lub hlis, ncaj qha txo qis sijhawm thiab cov nqi hloov khoom.
II. Impact Toughness: Hnav- tiv taus yam tsis muaj kev tawg, haum rau kev ua haujlwm nyuaj
Thaum ib txwm muaj siab -manganese steel muaj qee qhov kev sib tw, qhov sib ntxiv ntawm cov pas nrig hlau tuaj yeem ua rau kev lag luam - tawm ntawm qhov tawv tawv thiab txo qis, ua rau nws yooj yim tawg thaum crushing cov ntaub ntawv loj. Super- hnav- cov hlau tsis muaj zog, ntawm qhov tod tes, siv "kub- tswj kev forging + austempering" txheej txheem kom muaj kev nyuaj siab thaum tib lub sijhawm ua rau muaj kev cuam tshuam hnyav rau ntau dua lossis sib npaug li 25 J / cm², muaj peev xwm tiv taus qhov cuam tshuam tam sim ntawd ntau tshaj 1500 k. Txawm tias thaum crushing cov ntaub ntawv uas muaj cov khoom txawv teb chaws xws li hlau blocks thiab rebar, lub rauj lub taub hau yuav tiv thaiv kom txhob tawg los yog chipping. Qhov no ua rau nws tsim nyog rau kev siv crushing nyuaj xws li mining thiab kev tsim kho aggregates, txo cov kev cuam tshuam ntau lawm los ntawm kev puas tsuaj.
III. Crushing Efficiency: Txo kev siv hluav taws xob, nce kev tsim khoom
Lub super- hnav- tiv taus steel rauj taub hau muaj qhov smoother nto thiab siab dua cov qauv. Lub taub hau rauj lub taub hau ua haujlwm tau txais qhov "kho cov qauv tsim," uas txo cov khoom slippage thiab blockage thaum lub sij hawm crushing txheej txheem, txhim kho cov khoom siv efficiency los ntawm 10% -15%. Tsis tas li ntawd, lawv cov khoom siv ntau dua (7.85-7.90 g / cm³, piv rau 7.70-7.75 g / cm³ ntawm siab-manganese steel thiab alloy rods) kom ntseeg tau tias qhov hnyav tshaj qhov sib faib thiab ruaj khov centrifugal quab yuam thaum lub sijhawm ua haujlwm, txo qis kev siv zog ntawm 1% shaft-8%. Piv txwv li, siv 200 TPH lub khob hliav qab crusher nrog super-hnav-resistant steel rauj taub hau tuaj yeem txo qhov kev siv hluav taws xob txhua hnub los ntawm kwv yees li 50-80 degrees Celsius, uas ua rau muaj kev txuag hluav taws xob tseem ceeb hauv kev ua haujlwm ntev.
Txawm hais tias tus nqi yuav khoom ib leeg ntawm tus hnav super-cov hlau rauj lub taub hau yog siab dua me ntsis siab dua li cov hlau manganese siab ntxiv rau cov pas nrig, nws qhov zoo yog qhov tseem ceeb thaum xam los ntawm tus nqi ntawm tag nrho lub neej voj voog.
