Hom ntawm cov khoom siv refractory rau lub tshuab nqus tsev kho cua sov:

Hom ntawm cov khoom siv refractory rau lub tshuab nqus tsev kho cua sov:

 

1. Acidic refractory feem ntau yog hais txog refractory nrog SiO2 cov ntsiab lus ntau dua 93 feem pua. Nws lub ntsiab feature yog hais tias nws muaj peev xwm tiv taus qhov yaig ntawm cov kua qaub slag ntawm qhov kub thiab txias, tab sis nws yog ib qho yooj yim rau react nrog alkaline slag.

 

2. Basic refractories feem ntau xa mus rau refractories nrog magnesium oxide los yog magnesium oxide thiab calcium oxide ua lub ntsiab Cheebtsam. Cov refractories no muaj siab refractoriness thiab muaj zog tiv thaiv alkaline slag.

 

3. Aluminosilicate refractories xa mus rau refractories nrog SiO2-Al2O3 ua cov khoom tseem ceeb. Raws li lawv cov ntsiab lus Al2O3, lawv tuaj yeem muab faib ua semi-siliceous (Al2O3 15-30%), av nplaum (Al2O3 30-48%), siab alumina (Al2O3 ntau dua 48 feem pua) peb pawg.

 

4. Fusion-cam khwb cia refractory yog hais txog cov khoom siv refractory uas muaj qee yam zoo li cam khwb cia tom qab cov batch yog melted ntawm qhov kub thiab txias los ntawm ib txoj kev.

 

5. Neutral refractories hais txog cov refractories uas tsis yooj yim rau reacts nrog acidic los yog yooj yim slag nyob rau hauv high kub, xws li carbon refractories thiab chrome refractories. Qee tus kuj faib cov khoom siv high-alumina refractory rau hauv pawg no.

 

6. Tshwj xeeb refractories yog cov tshiab inorganic non-metallic cov ntaub ntawv tsim los ntawm cov tsoos ceramics thiab dav refractories.

 

7. Cov khoom siv tsis zoo refractory yog cov khoom sib xyaw ua ke ntawm refractory aggregate thiab hmoov, binder los yog lwm yam additives nyob rau hauv ib qho kev faib ua feem, uas yuav siv tau ncaj qha los yog tom qab ntxiv cov kua tsim nyog. Unshaped refractory khoom yog ib yam tshiab ntawm cov khoom siv refractory yam tsis muaj calcination, thiab nws cov refractoriness tsis qis dua 1580 degree.

Lub tshuab nqus tsev kub kho cov cuab yeej nqus tsev vacuum

 

1. Rau kev tsim cov khoom siv hlau tshwj xeeb;

 

2. Raws li kev kuaj mob, kev tshawb fawb thiab kev tsim cov qib steel tshiab tuaj yeem ua tiav, thiab tib lub sijhawm, qee qhov kev pabcuam tshawb fawb thiab thev naus laus zis tuaj yeem muab rau cov nroj tsuag steel.

Inorganic non-metallic cov ntaub ntawv nrog refractoriness saum 1580oC rau lub tshuab nqus tsev kho cua sov khoom

 

Cov ntaub ntawv refractory feem ntau xa mus rau cov khoom siv tsis muaj hlau tsis muaj hlau nrog cov refractoriness saum 1580oC. Nws suav nrog ntuj ores thiab ntau yam khoom tsim los ntawm qee cov txheej txheem raws li qee lub hom phiaj. Nws muaj qee yam khoom siv hluav taws xob kub thiab qhov ntim zoo, thiab yog cov khoom tsim nyog rau ntau yam khoom siv kub.
