Ntawm cov khoom siv hauv tsev, crushed slag sawv tawm rau nws tus nqi tsawg. Nws yog ib qho nyuaj rau nrhiav tau ib yam khoom uas yuav raug nqi tsawg dua li cov khoom siv no. Raws li qhov tshwm sim, tag nrho cov nqi ntawm tag nrho cov haujlwm yuav qis dua, uas yuav ua rau koj sib tw tau zoo dua hauv kev ua lag luam.
Slag crushed pob zeb - nws yog dab tsi
Cov khoom siv no yog cov khoom siv los ntawm kev lag luam steel. Yog tias tsis mus rau hauv cov ntsiab lus, peb tuaj yeem muab ob txoj hauv kev tseem ceeb rau "kev rho tawm" ntawm cov khoom no. Hauv thawj kis, pob zeb heaps sab laug tom qab siv cov hlau ua. Cov no tsuas yog cov pob zeb ntawm ntau qhov sib txawv, uas tau muab faib ua feem (qhov ntau thiab tsawg ntawm tus kheej qhov chaw) thiab tom qab ntawd lawv tau npaj rau kev siv tam sim. Txoj kev no yog qhov pheej yig tshaj plaws. Qhov thib ob kev xaiv muaj nyob rau hauv ib tug tshwj xeeb pouring slag ntawm ib tug tej yam nto, nws txias thiab tom qab crushing siv cov khoom tshwj xeeb. Nws hloov tawm me ntsis kim dua, tab sis cov khoom tawm los zoo dua.
Ntse thiab nta
yam ntxwv ntawm crushed slag tuaj yeem sib txawv. Lawv nyob ntawm yuav luag tag nrho ntawm qhov qubraw cov ntaub ntawv, raws li zoo raws li los ntawm cov technologies uas tau siv nyob rau hauv zus tau tej cov steel. Txawm li cas los xij, muaj ntau tus yam ntxwv uas tso cai rau peb txheeb xyuas cov khoom no kom raug ntau dua.
- Qhov ntom ntawm crushed slag yog siab dua granite (los ntawm 2950 kg / m 3 piv rau 2650 kg / m 3).
- Dej nqus kuj siab dua (rau granite - 0.2%, rau slag - ntawm 0.4 txog 7.3%).
- Frost tsis kam qis dua (15 cycles piv rau 300 rau granite).
Cais, nws yuav tsum hais txog lub zog compressive. Yog tias rau cov khoom siv granite txheem qhov ntsuas no yog 120 MPa, tom qab ntawd rau crushed slag nws tuaj yeem sib txawv ntawm ntau yam, pib ntawm 62 MPa (rau porous slag) thiab xaus ntawm 140 MPa (rau cov tooj liab-smelting analogue). Tib yam tuaj yeem hais txog qhov Performance index ntawm crushability. Rau crushed granite, tus yam ntxwv no yog 11%, thiab cov cim ntawm slag kuj txawv. Porous - 44%, tooj liab-smelting - 6%.
Daim ntawv thov
Zoo ib yam li lwm hom pob zeb crushed, cov khoom no yog siv rau ntau qhov chaw.
- Asph alt production.
- Ua pob zeb nrog kev txhim kho hluav taws.
- Tsim cov blocks thiab slabs rau cov tsev lag luam.
- paving txoj kev.
- Kev tsim cov vuas, cinder block thiab pob zeb.
- Kev tsim cov ntaub plaub.
- Cov khoom zoo nkauj tshaj plaws tuaj yeem siv rau hauv kev tsim toj roob hauv pes.
Feem ntau, nws tuaj yeem hloov pauv tau zooanalogues thiab yuav raug nqi ntau dua. Txawm li cas los xij, vim muaj cov yam ntxwv tshwj xeeb, tshwj xeeb tshaj yog vim tsis muaj Frost tsis kam, qee qhov kev siv cov tshuaj no yog tsis yooj yim sua. Tias yog vim li cas crushed slag tseem tsis tuaj yeem tshem tawm tag nrho granite, vim tias muaj ntau qhov chaw nyob rau thaj tsam ntawm Russia uas tsis tshua muaj qhov kub thiab txias tau suav tias yog qhov tseeb thiab nws yog qhov muaj cov tsev lag luam feem ntau ua. Hais txog tus nqi, koj yuav tsum xav txog ntau yam ntawm cov pob zeb no. Piv txwv li, qhov pheej yig tshaj plaws thiab, hais ncaj ncees, cov khoom siv tsis zoo uas tsis muaj qhov ntxeem tau muaj nyob rau hauv ib lub nyiaj. Thiab nws cov tooj liab-smelting analogue, uas yog tiag tiag yuav luag nyob rau hauv tsis muaj txoj kev inferior rau granite (thiab nyob rau hauv tej txoj kev txawm superior), yuav raug nqi me ntsis pheej yig dua li tej yam ntuj tso khoom.
Results
Lub ntsiab lus xaus los ntawm tag nrho cov saum toj no yog cov crushed slag yuav tsum tau xaiv raws li cov kev xav tau tam sim no, vim nws cov khoom sib txawv heev. Ntawd yog, koj yuav tsum nqa cov khoom siv uas muaj tag nrho cov yam ntxwv xav tau. Nyob rau hauv ib rooj plaub, nws yuav yog qhov yooj yim tshaj, ntxeem tau crushed slag, thiab nyob rau hauv lwm yam, tsuas yog nws cov tooj liab-smelting counterpart yuav ua.
