Tam sim no ntau lub tshuab muaj cuab yeej nrogtshwj xeeb txhuam thiab txhuam cov menyuamCov. Niaj hnub no, tus kws tshaj lij kev sib tw uas tsim txhuam txhuam, txhuam cov menyuam, hlau txhuam thiab cov txhuam kev lag luam yuav qhia ib qho ntawm cov tshuab, uas yog, txhuam cov menyuam nyob rau hauv lub tshuab ua kom zoo nkauj thiab ob peb txoj kev ua kom zoo nkauj ntawmsingeing tshuab.
Cov txhuam cov txhuam yog qhov tseem ceeb ntawm cov khoom lag luam txhuam, thiab tseem yog ib qho tseem ceeb ntawm cov khoomsingeing tshuabCov. Cov nplaim hluav taws kub ntawm lub tshuab hluav taws xob qub singeing yog qhov tsawg (feem ntau 700-800 the), thiab cov txheej txheem ntawm cov tshuab raj ntau ntawm cov yeeb yaj kiab feem ntau siv los txhim kho qhov zoo ntawm kev hu nkauj. Tab sis dhau los ntawm kev ua haujlwm ntev thiab kev soj ntsuam, nplaim taws kub ntawm lub qhov cub muaj qhov cuam tshuam loj rau qhov zoo ntawm kev hu nkauj. Ua kom cov nplaim hluav taws kub ntxiv tuaj yeem tsis tsuas yog ntxuav qhov kev hu nkauj, tab sis kuj txhim kho cov tsheb nrawm. Tam sim no, muaj ntau txoj kev los txhim kho kev ntsuas ntawm lub qhov ncauj hluav taws:
1. Rho hluav taws xob hom hluav taws kub lub qhov ncauj: qhov ncauj hluav taws yog nruab nrog tshwj xeeb zoo li tusrefractory cib, yog li hais tias qhov sib tov tuaj yeem hlawv hauv chav tsev me me ntawm lub pob zeb refractory tom qab lub qhov hluav taws xob. Tusrefractory cibyog cov khoom thauj kub-txias, uas tuaj yeem sau cov cua sov, txhim kho kev sib xyaw ua kom sov, thiab ntxiv dag zog rau cov txheej txheem sib txuas (nce mus txog 1300-1400.).
2. Cov tshuab hluav taws xob ntau: piv txwv li, sps-ii ob chav dav hlau hlawv ua nyob rau hauv Suav teb, ntawm lub hauv paus ntawm cov nplaim hluav taws kub hnyiab, cov hlawv tawm tau hloov mus ua tus thawj, cov theem nrab thiab cov pabcuam hluav taws xob, uas ua rau cov roj sib tov ua cov roj khov tsis ruaj khov, thiaj li yuav hlawv ntau dua, txhim kho cov nplaim taws kub kom sov, thiab ua kom cov nplaim taws tiaj thiab ruaj khov. Muaj lwm cov qauv qauv ntawm ob chav dav hlau hlawv, tab sis nws txoj haujlwm ua haujlwm zoo ib yam. Txhim kho qhov cub tawg ntawm rojsingeing tshuabtuaj yeem tig lub kaum ntse ntse, uas yooj yim rau kev tswj hwm degree singeing.
