Ntawm tag nrho cov ntaub ntawv uas tau siv dav thiab feem ntau siv, ob qho tib si hauv kev tsim kho kev lag luam thiab hauv lub neej txhua hnub, cov nplais zom zaws tsim nyog tau txais kev saib xyuas tshwj xeeb. Yog tsis muaj nws, nws ua tsis tau lub tsev lossis txoj kev.

Cov lus teb rau tag nrho koj cov lus nug txog slag tsoo tuaj yeem pom hauv kab lus no. Ntawm no peb yuav txiav txim siab cov txheej txheem tseem ceeb ntawm cov khoom, nws ntau yam thiab qhia koj qhov twg thiab yuav siv nws li cas.

Nws yog dab tsi?

Crushed slag yog ib qho ntawm cov khoom siv tseem ceeb hauv tsev uas feem ntau siv hauv kev tsim kho ntau yam qauv thiab cov qauv. Qhov no yog nws tus kheej. Nws yog los ntawm kev tsim khoom theem ob, vim nws tau txais los ntawm kev ua ntau yam khoom siv ntuj tsim hauv cov khoom lag luam.

Thaum cov hlau, tshuaj lom neeg, thiab cov khoom siv hluav taws xob tau ua tiav hauv lub qhov cub tawg, slag tau tsim los ntawm lawv, uas muaj cov ntxeem tau zoo dua thiab cov qauv ruaj khov.

Nws yog qhov pov tseg ntawm cov tshuab ua kom tawg tawg, uas tom qab ntawd tsoo cov tshuab mus rau ntau hom kev faib ua feem, thiab hu ua crushed slag, uas yog nrov heev niaj hnub no. Nws muaj tus lej zoo, uas suav nrog:

• dej tsis kam;
• mechanical tsis kam;
• tus nqi (tus nqi ntawm cov pob zeb tawg yog qhov siv tau, nws yog kwv yees li 30% qis dua tus nqi ntawm cov pob zeb sib tsoo ib txwm);
• kev ntseeg tau;
• zoo heev lub cev thiab kev tsis.

Tab sis slag kuj muaj qhov tsis zoo, uas txhua tus neeg siv khoom tseem yuav tsum paub txog . Ntawm lawv, nws yuav tsum tau sau tseg qhov sib txawv ntawm lub zog ntawm cov khoom siv hauv ib feem. Nws tuaj yeem suav nrog pov tseg los ntawm kev ua hlau thiab roj, thiab cov khoom sib txawv hauv qhov muaj zog. Tias yog vim li cas nws nyuaj rau nkag siab thiab kwv yees tias cov khoom yuav coj li cas, yog ib feem ntawm cov qauv tshwj xeeb. Vim li no, slag kev tsim kho tsis siv rau hauv kev tsim cov qauv loj thiab siab.

Cov yam ntxwv tseem ceeb

Zoo ib yam li lwm cov khoom siv hauv tsev, pob zeb tawg yog cov yam ntxwv thiab lub cev thiab cov yam ntxwv zoo, uas tau tswj hwm los ntawm cov ntaub ntawv tswj hwm GOST 5578-94 thiab 3344-83.

Raws li lawv, cov slag tsoo, uas tsim nyog rau kev siv ntxiv, yuav tsum muaj cov yam ntxwv hauv qab no:

• qhov sib zog ua kom muaj zog - M300 -M1200;
• feem pua ntawm impurities (hmoov av thiab av nplaum) - tsis ntau dua 3%;
• dej nqus coefficient - los ntawm 1.5% mus rau 4% ntawm tag nrho qhov hnyav ntawm cov khoom;
• te tiv taus coefficient - los ntawm 15 txog 300;
• chav kawm hluav taws xob - 1;
• lub zog - los ntawm 2.5 MPa txog 40 MPa;
• tej ceev ntawm cov khoom - los ntawm 400 kg / m³ rau 1600 kg / m³;
• yas - los ntawm 15% mus rau 35%;
• qhov hnyav ib m3 yog 1000 kg.

Hom kev txheeb xyuas

Slag crushed pob zeb, zoo li lwm yam khoom siv hauv tsev uas tau txais hauv cov txheej txheem crushing, tau muab cais ua cov feem me me

Loj-feem . Qhov loj me me ntawm cov khoom ntxhib yog 40-70, 70-120 hli. Cov pob zeb tsoo, cov khoom uas yog 40-70 mm loj, tau txiav txim siab ua tus qauv thiab tau siv hauv kev npaj ua cov pob zeb sib xyaw rau kev teeb tsa cov qauv loj, hauv kev tsim kho. Tab sis slag tsoo pob zeb 70-120 hli hais txog qhov tsis yog-tus qauv. Nws yog siv feem ntau rau kev kho kom zoo nkauj raws li kev kho kom zoo nkauj rau kab txaij, hauv qab ntawm lub pas dej lossis pas dej.

Fractional nruab nrab . Qhov loj me me ntawm cov khoom siv hauv nruab nrab ntawm qhov nruab nrab ntawm 20 mm txog 40 mm. Cov khoom siv no tsim nyog rau kev tsim cov qhob thiab cov pob zeb ua haujlwm ntxiv. Cov pob zeb tsoo ntawm qhov nruab nrab feem siv rau kev sib tov, uas yog siv hauv kev tsim kho txoj kev, kev tsheb nqaj hlau thiab kev tsim tsev.

Cov feem zoo . Cov feem no suav nrog cov pob zeb tawg, qhov loj me me uas yog los ntawm 5 hli txog 20 hli. Qhov no yog cov khoom siv feem ntau siv. Nws tau siv hauv cov txheej txheem ntawm kev ua cov pob zeb thiab cov pob zeb ua ke, ntxiv rau txhawm rau txhim kho cov choj thiab cov chaw hauv txoj kev.

Tshem tawm . Cov feem no suav nrog cov pob zeb tawg, qhov loj me me uas tsis ntau tshaj 5 hli. Lub peev xwm ntawm hom pob zeb tawg no yog kho kom zoo nkauj.

Lub xub ntiag ntawm cov feem sib txawv, qhov ntau thiab tsawg ntawm cov slag ua rau nws muaj peev xwm siv nws hauv ntau thaj chaw ntawm kev tsim kho.

Cov ntawv thov

Crushed slag yog cov khoom siv uas tau siv dav vim nws cov txheej txheem tsis zoo thiab cov yam ntxwv, ob qho tib si hauv kev ua haujlwm ntxhib thiab ua kom zoo nkauj tiav.

Nws yog siv hauv cov xwm txheej hauv qab no

• Hauv cov txheej txheem tsim cov cinder-qhob sib xyaw rau kev ua haujlwm kho thiab tsim kho.
• Raws li yog ib qho tseem ceeb hauv kev tsim cov cinder block. Crushed slag yog tus yam ntxwv ua kom muaj cua sov tsawg, yog li ntawd, lub cinder block ua los ntawm nws feem ntau yog siv rau kev tsim cov tsev nyob hauv thaj chaw uas muaj huab cua hnyav. Kev tiv thaiv te ntawm qhov thaiv no yog tsawg kawg f75.
• Raws li cov khoom siv rau kev txhaws thiab kev sib cog hauv cov txheej txheem ntawm kev kho dua qub thiab tsim txoj hauv kev tshiab.
• Hauv cov chaw tsim khoom tsim cov asphalt qhob. Crushed slag yog tiv taus cov neeg ua haujlwm nyuaj, hnav-tiv taus, yog li nws feem ntau siv los ua kev sib xyaw hauv cov txheej txheem ntawm kev kho lossis kho dua ntawm txoj kev.
• Hauv cov tuam txhab uas koom nrog kev tsim cov pob zeb wool rau rwb thaiv tsev ntawm thaj chaw. Nws yog pob zeb wool, uas muaj cov nplais slag, uas tau lees paub qhov ua tau zoo tshaj plaws ntawm cov cua sov rwb thaiv tsev thiab suab rwb thaiv tsev hauv chav.

Nws tuaj yeem txiav txim siab tias slag, uas yog qhov tseem ceeb ntawm cov khoom pov tseg, yog cov khoom siv tsis hloov pauv, tshwj xeeb tshaj yog rau kev tsim kho txoj kev . Tsis muaj ib lub tsev twg - tshiab lossis rov ua dua qub, hauv cov txheej txheem uas muaj cov nplais tawg, tau lees tias yuav ua haujlwm tau ntev.

Kev siv cov slag tsoo hauv kev tsim kho ua rau nws muaj peev xwm txo qis qis, nkag mus ntawm kev daws teeb meem . Yog li, cov khoom siv pab txhawm rau ntxiv dag zog, ntom ntom ntom ntom ntom ntom ntom ntom thiab dej tsis kam ntawm cov qauv.
