Kev sib tsoo slag ua hmoov yog ib qho uas pom ntau heev hauv kev lag luam cement thiab cov khoom siv hauv tsev. Yog li cov txheej txheem ntawm cov kab ntau lawm ntawm kev sib tsoo slag yog dab tsi? Cov kev sib txuas ntau lawm twg suav nrog hauvslag sib tsoo zebthiab cov khoom siv uas feem ntau siv hauvslag sib tsoo zeb kab ntau lawm.

Lub npe tag nrho ntawm slag yog granulated blast furnace slag, uas yog cov slag kub uas tawm ntawm lub cub tawg tom qab cov hlau thiab hlau cog smelt npua hlau. Tom qab cov slag tawm los, nws ncaj qha muab tso rau hauv dej kom txias, yog li nws tseem hu ua dej slag. Hauv peb cov cement thiab cov ntaub ntawv tsim kho, cov khoom siv cementitious feem ntau yog cov hmoov av tsim los ntawm kev siv slag, uas yog, hmoov slag. Yog li ntawd, cov chaw sib tsoo loj feem ntau raug tsim ze ntawm cov hlau cog kom sib tsoo cement clinker thiab cov hmoov av. Slag tuaj yeem sib xyaw nrog cement clinker rau kev sib tsoo los tsim slag cement, lossis nws tuaj yeem sib cais thiab tom qab ntawd sib xyaw.

Cov kab ntau lawm ntawm slag sib tsoo zeb nyob ntawm lub tshuab sib tsoo thiab cov txheej txheem tsim siv. Muaj ntau hom khoom siv rau kev sib tsoo slag, xws lislag ntsug roller zeb, lub tshuab zeb pob, lub tshuab zeb rau menyuam, lub tshuab zeb pas nrig, thiab lwm yam. Los ntawm qhov pom ntawm kev siv hluav taws xob thiab kev tiv thaiv ib puag ncig. Lub tshuab zeb slag ntsug muaj qhov zoo pom tseeb, yog li nws kuj tau txais tos los ntawm feem ntau ntawm cov neeg siv khoom downstream. Cov txheej txheem ntawmslag ntsug roller zebcov kab ntau lawm feem ntau suav nrog cov kev sib txuas hauv qab no:

1. Kev tsoo: cov slag loj yuav tsum tau tawg ua ntej, thiab qhov loj me me rau hauv kev sib tsoo yuav tsum tsawg dua 3 cm;

2. Kev ziab + kev sib tsoo: cov khoom siv uas raug tsoo raug pub rau hauv lub tshuab zeb thiab raug tsoo raws li lub zog ntawm lub tshuab sib tsoo. Cov pa roj sib tsoo ntws los ntawm lub cub cua kub kom sov, thiab tom qab ntawd tuaj yeem ziab cov khoom siv;

3. Kev ntsuas qib: cov khoom tawg raug cua tshuab mus rau hauv lub tshuab cais tawm, thiab cov khoom tsim nyog hla mus zoo, thiab cov khoom tsis tsim nyog txuas ntxiv poob rov qab thiab sib tsoo.

4. Kev Sau: cov khoom siv uas tau xaiv lawm yuav nkag mus rau hauv lub tshuab sau hmoov av kom paub txog kev sib cais ntawm cov khoom siv thiab roj. Cov khoom siv uas tau sau yuav raug xa mus rau cov txheej txheem tom ntej los ntawm lub qhov tso pa tawm. Feem ntau ntawm cov cua ntws koom nrog hauv lub voj voog tom ntej, thiab cov cua ntws ntau dhau yuav raug tso tawm mus rau huab cua;

5. Kev xa khoom: lub qhov tso tawm hauv qab lub tshuab nqus plua plav tuaj yeem thauj khoom ncaj qha thiab thauj mus rau qhov chaw los ntawm lub tshuab loj, lossis xa mus rau lub tsev rau khoom tiav lawm rau kev khaws cia los ntawm lub tshuab xa khoom.

Cov saum toj no tsuas yog ib qho kev qhia yooj yim rau cov txheej txheem ntawmslag ntsug roller zebkab ntau lawm. Yog tias koj xav paub ntxiv txog nws, thov hu rau peb.
