Ncaj ncaj

Tom qab annealing, cov khoom tau dhau los ntawm xya tus menyuam ncaj tshuab kom ua tiav txoj kev ncaj ntawm cov hlab.

Eddy tam sim no

Tom qab straightening, txhua lub raj yog dhau los ntawm eddy lub tshuab tam sim no los kuaj xyuas qhov tawg thiab lwm yam tsis xws luag.Tsuas yog cov raj uas dhau eddy tam sim no haum rau kev xa mus rau cov neeg siv khoom.

Ua tiav

Txhua lub raj yog oiled nrog corrosion resistant roj los yog varnished rau nto tiv thaiv thiab corrosion resistant raws li ib tug neeg yuav tsum tau, txhua lub raj kawg yog them los ntawm yas kawg lub kaus mom kom tsis txhob muaj kev puas tsuaj nyob rau hauv kev thauj mus los, cov cim thiab specs muab tso thiab cov khoom yog npaj txhij rau xa. .

Daim ntawv thov

Q355 Kub Rolled Carbon steel seamless kav yog feem ntau siv nyob rau hauv cov khoom siv nuclear, roj conveyance, petrochemical, shipbuilding thiab boiler industries, nrog cov yam ntxwv ntawm siab corrosion kuj ua ke nrog cov khoom tsim nyog.
