Castable rau Qab Qab

Castable rau ladle hauv qab yog corundum spinel cov khoom, tseem hu ua corundum spinel castable, uas yog cov khoom siv hluav taws xob zoo uas tsis hloov pauv cov khoom tiv taus spalling thiab slag corrosion. Corundum spinel castable siv rau hauv qab yog qhov zoo tshaj rau lwm cov ntaub ntawv pov tseg, nrog lub neej ua haujlwm ntev. Cov khoom tseem ceeb ntawm cov khoom yog Al2O3 thiab MgO, thiab cov qauv tseem ceeb yog theem periclase, qib corundum thiab theem spinel, Cov khoom lag luam yog cov khoom tsim nyog.

1, Nqe lus piav qhia ntawm Castable rau Qab Qab:
Cov txheej txheem tseem ceeb ntawm Castable rau Qab Qab yog spinel ntxhia theem, ib puag ncig los ntawm corundum theem thiab theem periclase. Nyob rau hauv lub chav kawm ntawm kev siv, cov khoom qhia tau hais tias superior tuab qauv, zoo heev xeb kuj thiab anti-spalling kuj. Cov ntaub ntawv tseem ceeb siv yog fused magnesia zoo, sintered spinel xuab zeb thiab fused dawb corundum xuab zeb.

3, Ua rau Castable rau Ladle Qab puas:

1) Castable rau Cov Qab Hauv Qab ua rau muaj cov ntsiab lus melting tsawg hauv cov txheej txheem ntawm kev siv kub, uas txo cov permeability thiab yaig tsis kam ntawm cov khoom thiab ua rau puas.

2) Kev sib txhuam slag ntawm cov khoom rhuav tshem qhov kev cog lus ntawm cov khoom, nce kev nkag mus ntawm slag, thiab ua rau kev puas tsuaj ntawm cov qauv khoom.

3) Qhov kub siab ntim khoom ruaj khov ntawm cov khoom raug rhuav tshem, thiab cov khoom raug puas los ntawm tev.

4, Cov yam ntxwv zoo ntawm cov khoom muaj raws li hauv qab no:

1) Txo lossis txo qis cov khoom lag luam qis, txhim kho qhov kub thiab txias qhov ua haujlwm tau zoo ntawm cov khoom, thiab ua kom qeeb lossis txo qis qhov ua rau corrosiveness ntawm slag.

2) Cov khoom lag luam matrix muaj kev nyab xeeb siab, ua haujlwm ruaj khov thiab tsim qauv, uas ua rau muaj peev xwm tiv thaiv kev nkag mus tau hauv kev siv.

3) Cov khoom xyaw ntawm cov khoom yog txhua qhov siab melting point raw cov ntaub ntawv, thiab ntim ruaj khov yog qhov zoo thaum ua haujlwm kub, uas txhim kho cov thermal poob siab ruaj khov thiab tiv thaiv kev ua kom tsis zoo.

5, Khoom Ntim:

Waterproof thiab noo-pov thawj kraft ntawv hnab. Lub sijhawm khaws cia hauv ib puag ncig qhuav ntau dua 6 lub hlis.

6.Qhov zoo tswv yim ntawm kev siv cov khoom lag luam, cov khoom tau raug xa tawm mus rau Russia, Australia, Oman

7.Peb yog tus muab khoom tshaj lij, leej twg tuaj yeem muab cov neeg siv khoom siv thev naus laus zis dawb, siv thiab lwm yam teeb meem.

Koj puas xav nrhiav tus kws tshaj lij ntawm cov khoom lag luam miv?

Koj puas xav nrhiav tus neeg muag khoom ruaj khov thiab ntseeg tau?
