Pickling Lines
Esmech Equipment offers Push-Pull, semi-continuous and continuous pickling lines.
Push-Pull pickling lines can process strips between 1.0mm to 12.0mm thick and 300mm to 2000mm wide.
For higher rate of production, Esmech Equipment 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 weld/stiching 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 (normally, free-fall loops) 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.
Apart from Low Carbon Steel, Esmech Equipment offers Pickling Lines for copper and copper-based alloys and commercial grades of Stainless Steel.
With over 50 pickling lines in operation, Esmech Equipment is the leading supplier of pickling lines in South Asia.
The important features of Esmech Equipment Pickling Lines are
-
01Turbo-TunnelThe pickling tanks are shallow tanks made of granite specially contoured to permit fast and trouble free threading. These tanks feature patented "Turbulent Acid System" which increases the rate of pickling by causing high turbulence in the tank and thus enabling high speeds with low treatment lengths.
-
02Lo-ChlorThe 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..
-
03Environment FriendlyEsmech Equipment process sections feature special sealings of the tanks and an efficient fume exhaust and scrubbing system to ensure no release of acid fumes within the plant and exhaust stack release of less than 10 mg/m3 of free HCl. HB Esmech lines can therefore conform to the most stringent air pollution control norms.
-
04Acid Recirculation SystemEsmech Equipment 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 60° are also made from FRVE. Other piping is made from FRVE/PP. Instrumentation, meters and MMIs are provided in the system for continuous monitoring of the process parameters.
-
05Low ConsumptionsEsmech Equipment 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.
-
06Low EffluentsThe waste Pickling Liquor is very rich in iron contents and therefore low in volume. The acidic water effluent is also extremely low.
-
07Additional Inline FeaturesAdditional features like Edge-Trimming, Skin-Passing, Coating,Cut-To-Length etc. can be incorporated as per the requirements of the customer.
