Push Pull Pickling Line with Shot Blasting

Push pull Pickling line with shot blasting   Push-pull Pickling is a semi-continuous production. This pickling line is characterized with less cost, less consumption, easier operation and fewer accidents. Moreover, it can acidwashing many kinds of incoming material. The pickling line capacity we supplied is among 100000~600000 tons annually.   Push-pull pickling lineTechnology Parameter: process method: push-pull shallow slot turbulence hydrochloric acid pickling medium: hydrochloric acid(≥31%) pickling density: 8~18% pickling time: minimum:25-30s pickling temperature: 65~85°C acid density: Max  200 g/L HCl   120g/LFe2   driven way: adopt SIEMENS AC frequency control system in main driving   Following is the data for push-pull pickling hot rolled strip with the annual output of 400000 tons.  

Acid	Output	Strip Thickness	Strip Width	Coil Weight	Max. line speed
HCl	400000 t/y	1.2~1.8~4.5 mm	500~1300 mm	Max 25 t	Max 120 m/min
