Kev sib koom ua ke ntawm cov graphite electrode yuav tsum zoo dua rau lub cev electrode, yog li ntawd, qhov sib koom ua ke muaj qis dua Coefficient ntawm thermal expansion thiab ntau dua Coefficient ntawm thermal expansion dua li cov electrode.
Qhov nruj los yog xoob kev sib txuas ntawm lub connector thiab lub qhov electrode ntsia hlau yog cuam tshuam los ntawm qhov sib txawv ntawm thermal expansion ntawm lub connector thiab electrode. Yog tias qhov sib koom axial Coefficient ntawm thermal expansion tshaj qhov electrode Coefficient ntawm thermal expansion, qhov kev sib txuas yuav raug loosened los yog loosened. Yog tias qhov sib koom ua ke Meridional Coefficient ntawm thermal expansion zoo heev tshaj qhov Coefficient ntawm thermal expansion ntawm electrode ntsia hlau qhov, electrode ntsia hlau qhov yuav raug rau expansion stress. Qhov sib txawv thermal expansion ntawm qhov sib koom ua ke thiab cov electrode qhov yog cuam tshuam los ntawm qhov kub thiab txias ntawm qhov khoom siv (CTE) thiab ntu ntu ntawm ob cov khoom siv graphite, thiab qhov ntsuas kub ntawm qhov ntsuas kub yog qhov ua haujlwm ntawm qhov ntsuas qhov nruj. Yog hais tias lub interface tiv thaiv kev tiv thaiv yog siab thaum pib, qhov no yog vim qhov chaw sib cuag nrog cov hmoov av (plua plav), kawg kev puas tsuaj, kev sib txuas tsis zoo, los yog vim kev ua haujlwm tsis zoo, uas yuav ua rau kev sib koom ua ke los ntawm ntau qhov tam sim no, ua rau overheating. qhov sib koom ua ke, qhov sib txuas siab ntawm qhov sib koom ua ke yog nyob ntawm qhov kev sib txhuam siab ntawm ob lub ntsiab lus, tab sis cov coefficient ntawm thermal expansion kuj yog ib qho tseem ceeb uas yuav tsum tsis txhob underestimated.
Hauv kev siv tswv yim, qhov kub ntawm qhov sib koom ua ke yog ib txwm siab dua li ntawm cov electrode ntawm tib txoj hauj lwm kab rov tav. Nrog rau qhov kub thiab txias, ob qho tib si electrode thiab sib koom ua ke tsim tawm kev nthuav dav. Seb cov electrode thiab qhov sib koom ua ke los yog tsis feem ntau nyob ntawm seb qhov thermal expansion coefficient ntawm electrode sib koom ua ke los yog tsis.
Txawm hais tias tsis muaj qhov zoo tshaj plaws nyob rau hauv lub ntiaj teb no, Hexi carbon tuam txhab sim nws qhov zoo tshaj plaws los txiav txim siab ntau yam thaum tsim cov graphite electrode pob qij txha, kom ua tiav qhov zoo tshaj plaws kom deb li deb tau thiab txhim kho cov khoom zoo kom deb li deb tau.
