XLY customizable high precision steel sheet acid pickling line with
reasonable structure
Pickling Line
We offer Push-Pull, semi-continuous and continuous pickling lines.
Push-Pull lines process one coil at a time, thus removing the need
for joining strips. This allows tremendous flexibility of operation
and ensures ease of operation and maintenance. As there is no need
for accumulators in such lines, these lines have very low cost of
investment and are very much cost-effective for medium volume of
production.
Push-Pull Pickling Lines can process strips between 1.0mm to 6.0mm
thick and 200mm to 2000mm wide.
For higher rate of production, we offer Semi-Continuous and
Continuous Pickling Lines.
In both these, continuous operation is achieved by
welding/stiching. Accumulators are provided at entry and exit to
allow continuous operation during the joining at the uncoiler end
and removal of coils at the recoiler end. In continuous lines, the
process section runs at a constant speed, while in semi-continuous
lines, where the accumulators are small in capacity, the speed of
the process section reduces during the coil jointing at the
uncoiler and changeover at the recoiler. Such installations are
cost-effective due to simplicity of the accumulator designs
The material from the Hot Rolling Mills is generally descaled and
chemically treated by passing it through a bath of hydrochloric or
sulphuric acid and rewound into coils to be sent to the reducing
mills.
Our engineering ensures maximum utilisation of the acid for
pickling and least wastage through effluents, thus resulting into
low consumption of acid per ton of production. Efficient recycling
of acidic water in the system reduces drastically the consumption
of water per ton.
Additional Features:
Additional features like Edge-Trimming, Skin-Passing, Coating,
Cut-To-Length etc. can be incorporated as per the requirements of
the customer.
