1. As tingting bilong kol droing:
Kol droing em i wanpela wok bilong stretim samting long rum tempereja. Long taim bilong stretim, ol samting i save go insait long 'die'. Long rot bilong presim samting long dai, ol i ken senisim 'cross-sectional area bilong samting bihainim ol narapela narapela seip bilong dai.
Taim ol i droim dispela samting long kol, dispela i nidim olsem ol i ken pulim dispela samting, olsem na strong bilong pulim long kol i mas antap long strong bilong dispela samting. Long wankain taim, kol droing i mas mekim tu olsem samting i no bruk, olsem na strong bilong droim kol i mas liklik long strong bilong samting.
2. Influens bilong kol droing long ol aloi
Sais
Bikpela wok bilong 'cold drawing' em long bosim sais bilong samting. Long taim bilong droim piksa long kol, 'mold' bai pulim na senisim samting. Ol kampani i ken bosim sais bilong samting bihain long ol i droim long kol taim ol i yusim ol narapela narapela 'mold'. Yumi mas luksave olsem sapos sais bilong pinis prodak i narakain tru long sais bilong samting pastaim long ol i droim long kol, bai hat long pulim long kol. Long dispela taim, ol i mas kisim planti 'cold drawing' long dispela samting. Long wankain taim, bikos 'cross-sectional area bilong samting i go daun long taim bilong kol droing, longpela bilong materiel bihain long kol droing bai go antap.
Seip
Narapela wok bilong 'cold drawing' em long senisim seip bilong 'cross-section' bilong 'alloy material'. Difrens long seip i kamap long difrens long mol. Olsem, sapos mol i skwe, orait kros-seksen bilong samting bihain long ol i droim long kol bai i skwe. Sapos ol i droim wanpela raunpela 'bar' long dispela rot, bai ol i kisim wanpela 'square bar' bihain long ol i 'cold roll'. Yumi mas luksave olsem sapos ol i laik senisim dispela samting na droim long kol, ol sais bilong samting pastaim na bihain long droim long kol i mas wankain.
Antap
Namba tri samting we kol i save mekim long 'alloy' em i pes bilong en. Taim samting i go insait long 'mold', bikos long 'friction' namel long 'mold' na samting, ol pipia i stap antap long samting i save raus. Dispela bai givim wankain 'polish' ifek long dispela samting. Long ol blakpela 'bar', bihain long ol i droim long kol, ol i kamap ol 'bright bar'. Tasol, planti taim bihain long droim long kol, mipela bai wok yet long polisim o grindim ol samting.
Ol samting bilong masin
Kol droing i gat impak tu long ol mekanik samting bilong aloi. Long taim bilong senis bilong metal, wanpela samting i save kamap strong, na kol droing tu em i wanpela kol senis proses, we tu i save kamapim wanpela samting i kamap strong. Long sampela taim, ol i ken yusim 'cold drawing' long bosim strong bilong 'alloy'. Tru tumas, dispela samting we i save kamap strong taim ol i droim long kol taim ol i ken pinisim long rot bilong hat tritmen.
