Pickling Lines

Our range of Pickling lines are characterized by high pickling rates, low-cost pickling operations and flexible production capability. The different pickling technologies include Push-Pull, Semi-Continuous and Continuous Pickling Lines.

Push-Pull Pickling Line are used for individual processing, thus removing the need for joining strip. These push pull pickling line provides excellent operational flexibility with the ease for frequently changing strip dimensions and steel grades. As there is no accumulator in the line, this technology is the most cost-effective method for medium volume of production. Push-Pull Pickling Line can process strips between 1.0mm to 6.0mm thick and 200mm to 2000mm wide.

Semi-Continuous & Continuous Pickling Line is used for high volume production with continuous operation by welding/stitching. The accumulators provided at the entry and exit that ensures a consistent flow in process during the joining and removal of coils at the recoiler end. In the continuous pickling line the process runs at constant speed, while in the noncontinuous line the speed of the process is reduced during the changeover or coil jointing due to small capacity accumulators. The installation Semi-Continuous & Continuous Pickling Line are highly cost-effective because of its simple accumulator design.

Turbulent Acidic Bath:
The shallow pickling tanks made of granite are specially contoured to permit fast and trouble free threading.

The continuous flow in the tank increases the rate of pickling by causing high turbulence of acid in the tank. This enables high speeds with low residence.
Spray Rinsing:
The pickling lines are provided with integrated washing system to ensure that strips carry very low amount after the pickling process is completed. This ensures long life of the rolling mill coolant in the subsequent cold rolling operation. It also contributes to longer shelf-life of pickled coils.

Acidic Recirculation System:
The Acidic Recirculation System is engineered to ensure good pickling quality and hassle free performance. All acid recirculation tanks and pipes are made form FRVE. The -pipes can withstand high temperature above 80° C. P.P. Instrumentation, meters and MMIs are integrated in the system for continuous monitoring of the process parameters.

Additional Inline Features:
Additional features like Edge-Trimming, Skin-Passing, Coating,Cut-To-Length etc. can be incorporated as per the requirements of the customer.

Environment Friendly:
Our process section have a properl sealing for the tanks and an efficient fume exhaust and scrubbing system to ensure low release of acid fumes within the plant.

Low Effluents:
The waste pickling liquor is low in volume due to high amount of iron content. The acidic water effluent is also extremely low.

Cost-effective:
The design of the line ensures maximum utilisation of the acid for pickling and least wastage through effluents, thus resulting in lower consumption of acid per ton production.

The recycling of acidic water in the system reduces the consumption of water.
