Cold Drawing Tubes rolling processing txoj cai

Siv cov yam ntxwv ntawm cov yas txias ntawm cov hlau hauv chav tsev kub, qee qhov siab yog siv rau saum npoo ntawm lub workpiece los ntawm dov cov cuab yeej, kom cov hlau ntawm qhov chaw ntawm lub workpiece tsim cov yas ntws, sau cov seem seem, thiab txo qhov chaw. roughness ntawm lub workpiece.
Vim tias cov yas deformation ntawm cov hlau nteg ntho hlau, cov txheej txheem saum npoo yog txias, thiab cov qauv sib luag yog tsim, tsim kev ntxhov siab txheej.
Ntxiv hardness thiab lub zog, yog li txhim kho cov hnav tsis kam, corrosion kuj thiab compatibility ntawm workpiece nto. Rolling yog ib txoj kev uas tsis yog txiav cov yas ua haujlwm.
