Abstract
The invention discloses a board pickling and grinding process comprising (1) process flows: board feeding, pickling, primary circulating washing, double-sided board grinding, secondary circulating washing, tertiary circulating washing, clear water washing, sucking dry, blowing dry by virtue of strong breeze, blowing dry by virtue of hot wind and board discharging; and (2) process parameters: moving speed: 1.2-1.6M/MIN; pickling concentration: H2SO4 3-5%; pickling pressure: 0.6-0.8 BAR; primary circulating washing pressure: 0.6-0.8 BAR; secondary circulating washing pressure: 1.2-1.5 BAR; and tertiary circulating washing pressure: 1.2-1.5 BAR. The board pickling and grinding process is reasonable and coordinated in process arrangement and can be used for effectively reducing reject rate and improving the product quality.
Description
Technical field
The present invention relates to pickling mill plate technique.
Background technology
There is processing step phenomenon inharmonious, irrational in existing pickling mill plate technique, produces re-treatment or excess processes sometimes, seriously affect quality product, and scrap rate is higher, require higher to employee's operating skill, cause product cost higher.
Existing pickling mill plate technology process step is tediously long in addition, and the distribution of each operation exists many irrational places.
Summary of the invention
In order to realize the object of the present invention, the present invention provides the pickling mill plate technique that a kind of procedure arrangement is reasonable, coordinate.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of pickling mill plate technique, comprises the steps:
1), technical process: enter plate �� pickling �� circulating water wash �� two-sided mill plate �� circulating water wash 2 �� circulating water wash, 3 �� clear water wash �� blot �� high wind blows dry �� hot blast drying �� ejecting plate;
2) processing parameter: translational speed: 1.2M/MIN �� 1.6M/MIN; Pickling concentration: H2SO43-5%; Pickling pressure: 0.6 �� 0.8BAR; Circulating water wash 1 pressure: 0.6 �� 0.8BAR; Circulating water wash 2 pressure: 1.2-1.5BAR; Circulating water wash 3 pressure: 1.2-1.5BAR.
Procedure arrangement of the present invention is reasonable, coordination, it is possible to effectively reduce scrap rate and quality product height.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
A kind of pickling mill plate technique, comprises the steps:
1), technical process: enter plate �� pickling �� circulating water wash �� two-sided mill plate �� circulating water wash 2 �� circulating water wash, 3 �� clear water wash �� blot �� high wind blows dry �� hot blast drying �� ejecting plate;
2) processing parameter: translational speed: 1.2M/MIN �� 1.6M/MIN; Pickling concentration: H2SO43-5%; Pickling pressure: 0.6 �� 0.8BAR; Circulating water wash 1 pressure: 0.6 �� 0.8BAR; Circulating water wash 2 pressure: 1.2-1.5BAR; Circulating water wash 3 pressure: 1.2-1.5BAR.
