Rollcon Engg. Co. offers 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, Rollcon Engg. Co. offers 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 important features of Rollcon Engg. Co. Pickling Lines are: Turbulent Acidic Bath: The pickling tanks are shallow tanks made of granite specially contoured to permit fast and trouble free threading. The specially arranged flow of acid in the tanks increases the rate of pickling by causing high turbulence of acid in the tank & thus enabling high speeds with low residence time & hence less length of the pickling tanks. Spray Rinsing: The special washing systems after the acid treatment are provided to ensure that the strips carry very low chlorides which helps in prolonging the life of the rolling mill coolant in the subsequent cold rolling operation, apart from ensuring longer shelf-life of pickled coils.. Acidic Recirculation System: Rollcon Engg. Co. fully engineers the acid recirculation system to ensure good pickling quality and trouble free performance. All acid recirculation tanks are made from FRVE. All piping carrying acid at temperatures above 80° C. are also made from FRVE/Special grades of P.P. Instrumentation, meters and MMIs are provided 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: Rollcon Engg. Co. process sections feature properl sealings of 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 very rich in iron contents and therefore low in volume. The acidic water effluent is also extremely low. Low Consumptions: Rollcon Engg. Co. 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.
