Tundish Well Block Thermal Shock Resistance

Tundish zoo blocks raug thermal shock thaum nruam casting hauv kev lag luam steel. Thermal shock tshwm sim thaum muaj qhov kub thiab txias hloov sai, ua rau cov khoom siv refractory nthuav dav lossis cog lus sai, ua rau tawg, tawg lossis tawg.

Lub thermal poob siab tsis kam ntawm tundish zoo blocks yog cov cuab yeej tseem ceeb uas txiav txim siab lawv lub peev xwm los tiv thaiv qhov kub thiab txias thaum lub sij hawm casting txheej txheem. Lub siab thermal poob siab ua haujlwm kom ntseeg tau tias cov pob zeb tundish yuav tsis tawg lossis tawg vim thermal cycling.

Lub thermal shock kuj ntawm tundish zoo blocks nyob ntawm ntau yam, xws li:

Cov khoom muaj pes tsawg leeg: Hom thiab tus nqi ntawm cov ntaub ntawv refractory siv nyob rau hauv tundish zoo thaiv cuam tshuam nws thermal shock resistance. Piv txwv li, magnesia-carbon tundish zoo blocks muaj thermal shock kuj zoo heev vim muaj thermal conductivity ntawm carbon.

Porosity: Lub porosity ntawm tundish zoo thaiv cuam tshuam nws cov thermal shock tsis kam. Cov porosity siab tuaj yeem ua rau qis dua thermal poob siab vim tias muaj kev pheej hmoo ntau dua ntawm cov dej noo nkag thiab tawg tom qab.

Cov txheej txheem tsim khoom: Cov txheej txheem tsim khoom siv los ua cov pob zeb tundish tuaj yeem cuam tshuam lawv cov thermal shock. Tundish zoo blocks uas yog tsim los ntawm kev vibration casting txheej txheem, piv txwv li, muaj ntau dua thermal shock tsis kam vim lawv cov tuab thiab cov qauv zoo ib yam.

Kev khiav hauj lwm tej yam kev mob: Cov kev khiav hauj lwm tej yam kev mob ntawm lub tundish, xws li tus nqi casting thiab kub gradient, kuj yuav cuam tshuam lub thermal shock tsis kam ntawm tundish zoo blocks.
