A. Uhlolojikelele lokugeleza kwenqubo
I-hot rolling (extrusion steel seamless tube) : ishubhu eliyindilinga billet → ukushisa → ukubhobozwa → ukugoqeka okuphakeme okuthathu, ukugoqa okuqhubekayo noma ukukhishwa → ukukhishwa kweshubhu → ukusika (noma ukunciphisa) → ukupholisa → i-billet → ukuqondisa → ukuhlolwa kwe-hydrostatic (noma ukutholwa kwamaphutha) → ukumaka → isitoreji.
Ishubhu lensimbi elibandayo (eligoqiwe) elingenamthungo: ishubhu eliyindilinga billet → ukushisisa → ukubhoboza → isihloko → annealing → pickling → uwoyela onamathela (ithusi elicwebezelayo) → umdwebo obandayo odlula izinto eziningi (ukugoqeka okubandayo) → billet → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa kwe-hydrostatic (ukutholwa kwamaphutha) → ukumaka → isitoreji.
