Blast furnace hla yog cov cuab yeej tseem ceeb siv los thauj cov pa roj, coke, hlau ore thiab lwm yam khoom siv. Ntawm lawv, cov hlau ore yog cov khoom siv tseem ceeb tshaj plaws ntawm qhov cub tawg, uas muaj kev cuam tshuam tseem ceeb ntawm cov khoom tsim tawm thiab qhov zoo ntawm qhov cub rauv slag thiab molten hlau. Yog li ntawd, kev siv cov khoom siv-resistant ceramic linings ntawm blast furnace skips plays lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov cuab yeej, txhim kho kev tsim khoom thiab txhim kho cov khoom zoo.
Ua ntej ntawm tag nrho cov, cov hlau ore cov ntaub ntawv thauj los ntawm blast furnace hla lub tsheb yog corrosive thiab abrasive rau ib yam twg. Cov hlau ore muaj qee qhov nyiaj ntawm silicon, calcium, magnesium thiab lwm yam khoom, uas ua rau muaj tshuaj lom neeg nrog cov qauv hlau thiab ua rau corrosion. Nyob rau tib lub sij hawm, hlau ore kuj muaj ib tug tej yam abrasiveness ntawm abrasiveness, uas yuav ua rau hnav thiab abrasion nyob rau saum npoo ntawm cov khoom thiab cuam tshuam lub neej ntawm cov khoom. Kev siv cov khoom siv-resistant ceramic liners tuaj yeem daws cov teeb meem no zoo dua, vim tias cov ntaub ntawv ceramic muaj hardness siab, zoo heev hnav tsis kam thiab corrosion kuj.
Qhov thib ob, cov khoom siv hlau hlau yuav ua rau muaj kev vibration thiab cuam tshuam thaum lub sij hawm kev thauj mus los ntawm lub tshuab hluav taws xob tawg hla tsheb. Vim tias lub tshuab hluav taws xob tawg hla yuav tsum muaj kev ruaj ntseg los ntawm kev sib txhuam ntawm cov log lossis txoj kab thiab hauv av thaum tsav tsheb. Cov khoom siv hlau ore yuav ua rau muaj kev vibration thiab cuam tshuam rau hauv lub tshuab hluav taws xob blasting tshuab, uas yuav ua rau qhov hnyav ntawm cov khoom siv. Xaiv qhov raug hnav-resistant cov khoom siv ceramic tuaj yeem txo qhov tshwm sim ntawm cov teeb meem no, yog li txo cov khoom siv tsis ua haujlwm thiab cov nqi kho.
Thaum kawg, kev siv cov hnav-resistant ceramic linings ntawm blast furnace skips tuaj yeem txhim kho kev tsim khoom thiab cov khoom zoo. Txij li thaum cov khoom siv ceramic muaj qhov coefficient ntawm kev sib txhuam, nws tuaj yeem txo qhov adhesion thaum thauj khoom thiab txhim kho kev thauj khoom. Nyob rau tib lub sijhawm, thaum lub sijhawm thauj mus los, vim hnav thiab corrosion, thiab lwm yam, cov pob me me yuav raug tso rau ntawm qhov chaw ntawm cov khoom siv. Cov pob no yuav cuam tshuam rau cov khoom siv fluidity, cuam tshuam rau kev khiav thiab kev faib tawm ntawm cov hlau ore, thiab txo cov kev ua haujlwm ntawm lub qhov cub tawg. thiab cov khoom zoo. Qhov saum npoo ntawm hnav-resistant ceramic liner yog du, nrog ob peb protrusions, uas yuav tsis cuam tshuam cov ndlwg ntawm cov ntaub ntawv, thiab tuaj yeem txhim kho kev tsim khoom thiab cov khoom zoo.
