XLY customizable high precision steel sheet acid pickling line with reasonable structure
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 like Edge-Trimming, Skin-Passing, Coating, Cut-To-Length etc. can be incorporated as per the requirements of the customer.
