Bututun ƙarfe mara nauyi

Saboda tsarin masana'anta ya bambanta, an raba shi zuwa bututun ƙarfe mai zafi (extruded) bututun ƙarfe mara ƙarfi da bututun ƙarfe mai sanyi (birgima) bututu iri biyu.

A.Bayanin kwararar tsari

Hot rolling (extruded sumul karfe tube): zagaye tube billet → dumama → perforation → uku-roll giciye mirgina, ci gaba da mirgina ko extrusion → tube tube → size (ko rage) → sanyaya → blank tube → mikewa → ruwa matsa lamba gwajin (ko gano lahani) → marking → ajiya.

Zane mai sanyi (birgima) bututun ƙarfe mara ƙarfi: zagaye bututu billet → dumama → perforation → kan gaba → annealing → pickling → oiling (copper plating) → zane mai sanyi da yawa (juyawa mai sanyi) → bututu mara kyau → maganin zafi → daidaitawa → gwajin matsa lamba na ruwa (gano kuskure) → alama → ajiya.
