Push Pickling Line Characteristics of pickling process


     Push Pickling Line Starting from the stepping beam, including uncoiler, flash welding machine, inlet movable sleeve, etc., until the front of the breaker (excluding the breaker) is the entrance section.The steel coil is loaded on the stepping beam at the entrance of the production line. 

     The entry operator verifies the incoming coil. The last position of the stepping beam is a saddle roller where the operator removes the strapping of the coil. Two measuring stations behind the saddle roll measure the width and outside diameter of the coil to automatically mount the coil to the uncoiler· on and on the uncoiler and the saddle roller to the middle coil.The entrance section provided by d 'arry is configured with 2 uncoiling machines.

     Push Pickling Line In contrast to the conventional scheme with processor, this scheme has the following advantages:

      a) steel coil head preparation and a superthick tail section are performed according to prediction. This approach has shorter entry cycle time, less loop length, less space required, and lower investment costs (related to the length of the production line).Instead of a processor that requires a prep station to handle the coil head, the tail shear before welding must be done online, with the result that the inlet cycle time is prolonged.

     B) is equipped with 2 uncoiling machines to ensure the high efficiency of the production line. In fact, when the equipment on one uncoiling line appears, the production can be continued even if the speed of the other uncoiling line is slowed down. Instead of a processor configuration, if the entry segment fails, the production line must stop, and can only begin production after the fault is cleared.

     C )is equipped with two uncoiling machines on a production line for uncoiling, with the head perforating to the cutting, according to the indication of cutting the extra thick part: if there is a fault during these operations, the operator has time to repair it, without stopping the production line or reducing the speed of the pickling section. 

The processor configuration is less flexible, and any failure in the stripper and shear phases indicates an increase in entry cycle time.

   Push Pickling Line The number of devices required for the entry segment of the d-processor configuration is less than that required for the two-coiler configuration. However, the mechanical complexity of the first scheme makes the investment costs of the two schemes comparable. During the operation of the production line, the potential is obviously located on one side of the two coiler schemes.When a steel coil is opened and processed by the first uncoiler, the next coil is loaded onto the second uncoiler. The strip passes through the leveller to the shears for head preparation. The strip goes up to the steering roller, where the two uncoiling lines meet.

      When the current coil is finished, cut off the extra thick strip at the shear and start welding the joint coil. The tail of the just-completed coil is excised at the shear section during the welding cycle.A welding machine is connected to the end to ensure continuous pickling. 

     The welder is capable of welding the welds that can be rolled in a reversible cold rolling mill (if the pickling line is produced by merging two inlet coils) and in a future continuous rolling mill.In order to reduce the total investment, we provide flexible steel sleeves with low profile design to minimize plant height. It was first developed by danieli and has been proven by practice and has been used for more than a decade.Feed the strip steel into the pickling section at the entry loop at the welding stage.

     Push Pickling Line In the leveling machine during the replacement of the work roller storage, from pickling section of the strip. The outlet looper stores the strip steel from the pickling section during the trimming shearing width adjustment, the steel coil tail off and the reel uncoiling. The speed of the tandem mill is independent of the speed of the pickling line.
