Airtight acid cleaning process section, strip material are by acidproof roller-way drive transfer, and all acidproof roller transmissions are speed control by frequency variation, and are reversible.The nitration mixture acid cleaning process selects for use nitric acid and hydrofluoric acid to mix as pickle solution, the nitration mixture acid cleaning process is when implementing the pickling operation, the strip material moves under the linear velocity of setting, be distributed in the outer acid solution recycle system of nitration mixture pickling enclosed hood and carry out corresponding acid solution circulation support, the strip material that is traveling in the pickling enclosed hood is carried out the continuous spray pickling in upper and lower surface, the strip material sent under can effect the water cleaning section and clean then and roll off the production line the end acid cleaning process after the oven dry when pickling finishes back strip material at its pinch roll.The nitration mixture acid cleaning process can satisfy the acid cleaning process requirement of different-alloy kind by suitably adjusting mixed acid liquid concentration, temperature, travel line speed.
Airtight final clear (brush) washes process section, is furnished with independently water circulation system, is provided with acidproof brush roll in the washing enclosed hood, and final clear (brush) section of washing is divided into one, two, three.The first step adopts spray to add and scrubs technology, and second and third level adopts high-pressure spraying formula to clean, and the upper and lower surface of strip material after can guaranteeing like this to clean is in the height clean conditions and enters baking zone and dry.
Drying system is made up of warm air drying clearance type drying unit, and hot air source adopts Electric heating, when the strip material after being cleaned is walked on the stoving process section, enters pickling blanking section with the clearance type drying unit after with the upper and lower surperficial moisture content flash baking of strip material.
Pickling blanking section is arranged on the rear portion of pickling unit oven dry section, the strip material after the oven dry will enter that the blanking section is sheared, segmentation, batch, blanking.This section is made up of pinch roll, spiral-plate cutting agency, shearing machine, pinch roll, reeling machine etc.
Pickling unit off-set facility comprises: acid circulation system, final water clear (brush) are washed the recycle system, soda acid supply station etc.
Technical scheme is the semicontinuous compound pickling unit of alloy plate strip, mainly comprise the pre-washing process section, airtight acid cleaning process section, airtight washing section, purge the stoving process section, the pickling unit recycle system, finish acid cleaning process, it is characterized in that: this unit one line arranges, strip material acid cleaning process linear running, pickling material loading section is by the hydraulic lifting feeding cart, Abrollhaspel, flexible guide plate, heading machine, levelling arm, pinch roll, the sheet material feed mechanism, entry loop, the sheet material charging roller connects composition successively, airtight pre-washing process section, arrange Pickled track in the airtight acid cleaning process section, acidproof carrying roller, arrange acidproof brush roll in the airtight washing section, have sprinkling system on each section, each sprinkling system connects the recycle system, connect the oven dry section behind the airtight washing section, pickling blanking unit, by plate cutting mechanism, hydraulic pressure is cut, reeling machine, trolley under the hydraulic lifting, the plate cutting roller-way arranges composition successively, the recycle system and airtight pre-washing process section, airtight acid cleaning process section, airtight washing section connects, and is used to supply service water and acid solution.
