1. Cov khoom siv txheej tuab tsim nyog

Lub tshuab zeb ntsug ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev sib tsoo cov khoom siv txaj. Lub txaj khoom ruaj khov yog qhov yuav tsum tau ua rau kev ua haujlwm tas mus li thiab ruaj khov ntawm lub tshuab zeb ntsug. Yog tias cov txheej khoom tuab dhau, qhov ua tau zoo ntawm kev sib tsoo yuav qis; yog tias cov txheej khoom nyias dhau, nws yuav yooj yim ua rau lub tshuab zeb co. Thaum ntxov siv lub tes tsho dov thiab daim ntaub sib tsoo disc, qhov tuab ntawm cov txheej khoom siv raug tswj ntawm kwv yees li 130 hli, uas tuaj yeem tsim cov txheej khoom ruaj khov thiab tswj qhov hnyav ntawm lub tshuab zeb ntsug kom hloov pauv hauv qhov ntau thiab tsawg tsim nyog;

Thaum siv cov tes tsho dov ntsug thiab cov phaj sab hauv tau dhau lub sijhawm khiav, qhov tuab ntawm cov txheej khoom yuav tsum tau nce ntxiv kom tsim nyog li 10 hli, kom cov txheej khoom ruaj khov dua, tuaj yeem ua rau muaj kev sib tsoo zoo tshaj plaws, thiab ua rau cov zis txhua teev nce ntxiv; cov tes tsho dov thiab cov phaj sab hauv hnav rau theem tom qab, qhov tuab ntawm cov txheej khoom yuav tsum tau tswj ntawm 150 ~ 160 hli, vim tias cov txheej khoom tsis sib npaug rau theem tom qab ntawm kev hnav, qhov cuam tshuam sib tsoo tsis zoo, qhov ruaj khov ntawm cov txheej khoom tsis zoo, thiab qhov tshwm sim ntawm kev ntaus lub pin tso kho tshuab yuav tshwm sim. Yog li ntawd, qhov siab ntawm lub nplhaib khaws cia yuav tsum tau kho raws sijhawm raws li kev hnav ntawm cov tes tsho dov ntsug thiab phaj sab hauv kom tswj tau qhov tuab ntawm cov txheej khoom tsim nyog.

Thaum lub sijhawm tswj hwm hauv nruab nrab, qhov tuab ntawm cov txheej khoom siv tuaj yeem txiav txim siab los ntawm kev soj ntsuam cov kev hloov pauv ntawm cov kev ntsuas xws li qhov sib txawv ntawm lub siab, tus tswv tsev tam sim no, kev co ntawm lub zeb, qhov kub ntawm qhov hluav taws xob sib tsoo, thiab qhov tam sim no ntawm lub thoob slag, thiab lub txaj khoom ruaj khov tuaj yeem tswj tau los ntawm kev kho qhov pub mis, qhov siab sib tsoo, qhov ceev ntawm cua, thiab lwm yam, thiab ua qhov kev hloov kho sib xws: nce qhov siab sib tsoo, nce cov khoom siv hmoov zoo, thiab cov txheej khoom siv ua nyias dua; txo qhov siab sib tsoo, thiab cov khoom siv disc sib tsoo ua coarser, thiab raws li cov khoom siv slagging ua ntau dua, thiab cov txheej khoom siv ua tuab dua; qhov ceev ntawm cua hauv lub zeb nce ntxiv, thiab cov txheej khoom siv ua tuab dua. Kev ncig ua rau cov txheej khoom siv tuab dua; txo cov cua txo cov kev ncig sab hauv thiab cov txheej khoom siv ua nyias dua. Tsis tas li ntawd, cov dej noo ntawm cov khoom siv sib tsoo yuav tsum tau tswj hwm ntawm 2% txog 5%. Cov khoom siv qhuav dhau thiab zoo dhau los muaj cov kua dej zoo thiab nyuaj rau tsim cov txheej khoom ruaj khov. Lub sijhawm no, qhov siab ntawm lub nplhaib khaws cia yuav tsum tau nce ntxiv, qhov siab sib tsoo yuav tsum tau txo qis, lossis qhov siab sib tsoo yuav tsum tau txo qis. Cov dej raug txau rau sab hauv (2% ~ 3%) kom txo cov khoom siv tsis yooj yim thiab ua kom cov txheej khoom ruaj khov.

Yog tias cov khoom ntub dhau lawm, qhov chaw ua batching, qhov ntsuas siv, lub qhov cua kaw, thiab lwm yam yuav khoob, daig, thaiv, thiab lwm yam, uas yuav cuam tshuam rau kev ua haujlwm ruaj khov ntawm lub zeb, yog li cuam tshuam rau lub sijhawm ntawm qhov chaw ua haujlwm. Kev sib xyaw ua ke ntawm cov yam saum toj no, kev tswj hwm cov txheej khoom ruaj khov thiab tsim nyog, tswj kom qhov kub thiab txias ntawm lub zeb tawm thiab qhov sib txawv ntawm lub siab me ntsis siab dua, thiab ua kom cov khoom ncig zoo yog cov txheej txheem ua haujlwm zoo los ua kom muaj ntau lawm thiab txuag hluav taws xob. Qhov kub thiab txias ntawm lub zeb thawj theem feem ntau tswj tau ntawm 95-100 ℃, uas ruaj khov heev, thiab qhov sib txawv ntawm lub siab feem ntau yog nyob ib puag ncig 6000-6200Pa, uas ruaj khov thiab muaj txiaj ntsig zoo; qhov kub thiab txias ntawm lub zeb theem thib ob feem ntau tswj tau ntawm ib puag ncig 78-86 ℃, uas ruaj khov heev, thiab qhov sib txawv ntawm lub siab feem ntau yog nyob nruab nrab ntawm 6800-7200Pa. Ruaj khov thiab muaj txiaj ntsig zoo.

2. Tswj qhov cua ceev tsim nyog

Lub tshuab zeb ntsug yog lub tshuab zeb uas siv cua los, uas feem ntau yog siv cua los ncig thiab thauj cov khoom siv, thiab qhov cua yuav tsum tsim nyog. Yog tias qhov ntim cua tsis txaus, cov khoom siv raw tsim nyog tsis tuaj yeem coj tawm raws sijhawm, cov txheej khoom siv yuav tuab, qhov ntim slag yuav nce ntxiv, cov khoom siv thauj khoom yuav siab, thiab cov zis yuav txo qis; yog tias qhov ntim cua loj dhau, cov txheej khoom siv yuav nyias dhau, uas yuav cuam tshuam rau kev ua haujlwm ruaj khov ntawm lub tshuab zeb thiab ua rau lub zog siv ntawm lub kiv cua ntau ntxiv. , yog li ntawd, qhov ntim cua ntawm lub tshuab zeb yuav tsum phim qhov tso zis. Qhov ntim cua ntawm lub tshuab zeb ntsug tuaj yeem hloov kho los ntawm qhov ceev ntawm lub kiv cua, qhov qhib ntawm lub kiv cua, thiab lwm yam.
