Lub thermal expansion coefficient ntawm magnesium bricks yog loj, thiab yuav tsum tau them nyiaj mloog mus rau thermal shock teeb meem.

 

Silicon carbide cib

Nta: siab thermal conductivity, hnav tsis kam, thiab zoo heev thermal shock kuj.

Daim ntawv thov: siv nyob rau hauv lub qhov cub rauv taws, lub qhov cub npog, burner thiab lwm qhov chaw ntawm lub qhov cub coke uas yuav tsum tau ceev cua sov dissipation.

Nco tseg:

Silicon carbide bricks yog kim thiab yuav tsum tau xaiv kom tsim nyog.

Tsis txhob sib cuag nrog cov roj oxidizing muaj zog tiv thaiv oxidation.

 

Refractory castables

Nta: kev tsim kho yooj yim, kev ncaj ncees zoo, thiab zoo heev thermal shock kuj.

Daim ntawv thov: Siv rau kev kho coke qhov cub, qhov chaw zoo nkauj thiab cov khoom siv casting.

Nco tseg:

Tus nqi ntawm cov dej ntxiv thaum lub sij hawm tsim kho yuav tsum tau tswj nruj me ntsis kom tsis txhob cuam tshuam lub zog.

Qhov kub yuav tsum tau nce qeeb thaum lub sij hawm ci kom tsis txhob tawg.

Refractory fiber ntau

Nta: lub teeb yuag, zoo thermal rwb thaiv tsev, thiab zoo heev thermal shock kuj.

Daim ntawv thov: Siv rau txheej rwb thaiv tsev ntawm coke ncu kom txo cov cua sov.

Nco tseg:

Refractory fibers tsis resistant rau txhua yam cuam tshuam thiab yuav tsum tau zam los ntawm kev puas tsuaj rau sab nraud.

Shrinkage tej zaum yuav tshwm sim nyob rau hauv lub sij hawm ntev kub thiab yuav tsum tau mus xyuas tsis tu ncua.

Corundum cib

Nta: tsis tshua muaj siab refractoriness (tshaj 1800 ° C) thiab muaj zog corrosion kuj.

Daim ntawv thov: Siv nyob rau hauv high-temperature thiab high-erosion qhov chaw ntawm coke ncu, xws li ib ncig ntawm burners.

Cov kev ceev faj:

Corundum bricks yog kim thiab yuav tsum tau xaiv kom tsim nyog.

Them mloog mus rau lub compactness ntawm cib pob qij txha thaum lub sij hawm tsim kho.

2. Kev ceev faj rau kev siv cov khoom siv coke cub refractory
Kev xaiv khoom

Xaiv cov ntaub ntawv refractory tsim nyog raws li qhov kub ntawm qhov sib txawv ntawm qhov cub coke, corrosive media (acidic lossis alkaline) thiab cov khoom siv thauj khoom.

Tsis txhob siv cov khoom siv hluav taws xob qis hauv qhov kub thiab txias los tiv thaiv cov khoom tsis ua haujlwm.

Kev tsim kho zoo

nruj me ntsis tswj qhov loj ntawm cov pob qij txha cib thiab siv cov av nkos refractory tsim nyog los xyuas kom meej qhov ntom ntawm masonry.

Rau refractory castables, kev tsim kho yuav tsum tau ua raws li qhov sib piv kom tsis txhob muaj dej ntau ntxiv cuam tshuam rau lub zog.

Qhov cub ci ua haujlwm

Tshiab tsim los yog kho coke qhov cub yuav tsum tau ci. Qhov kub thiab txias yuav tsum tau maj mam nce thaum lub sij hawm ci kom tsis txhob tawg los yog tev ntawm cov ntaub ntawv refractory vim qhov kub hloov pauv sai.

Kev tu txhua hnub

Tsis tu ncua xyuas qhov hnav, yaig thiab tawg ntawm coke cub refractory cov ntaub ntawv thiab kho lawv raws sijhawm.

Tsis txhob ua haujlwm kub dhau ntawm coke qhov cub kom tiv thaiv kev puas tsuaj ntxov rau cov khoom siv refractory.

Cia thiab khaws cia

Cov ntaub ntawv refractory yuav tsum tau muab cia rau hauv qhov chaw qhuav kom tsis txhob ya raws (tshwj xeeb tshaj yog magnesia bricks thiab refractory castables).

Cov ntaub ntawv refractory ntawm cov khoom sib txawv yuav tsum tau muab cais kom tsis txhob muaj kev ntxhov siab.

Cov ntsiab lus
Cov khoom siv refractory feem ntau siv hauv coke ncu muaj xws li silica cib, siab alumina cib, av nplaum cib, magnesia cib, silicon carbide cib, refractory castables, refractory fibers thiab corundum cib. Thaum siv, cov ntaub ntawv yuav tsum raug xaiv raws li kev ua haujlwm tshwj xeeb, thiab yuav tsum tau them nyiaj rau kev tsim kho kom zoo, kev ua haujlwm ntawm qhov cub thiab kev saib xyuas txhua hnub kom ntev lub neej kev pab cuam ntawm lub qhov cub coke.
