B. The kpo oku okpomọkụ bụ edo, na-agbalịsi ike ime ka okpomọkụ okpomọkụ dị iche n'etiti longitudinal na transverse ntụziaka nke tube oghere adịghị ukwuu karịa ± 10 ° C;
C. Enwere obere mfu ọkụ na-ere ọkụ, na tube billet kwesịrị igbochi oke-oxidation, mgbawa elu, njikọta, wdg n'oge usoro kpo oku.
D. The kpo oku usoro bụ ihe ezi uche dị na ya, na ezi uche nhazi nke okpomọkụ okpomọkụ, kpo oku ọsọ na okpomọkụ oge (jide oge) kwesịrị ime nke ọma iji gbochie tube billet si ekpo oke ọkụ ma ọ bụ ọbụna overburning.
