  • Gauge tolerance, flatness, roughness and roll-changing requirements
Steel Strip Electrolytic Cleaning Line (ECL)

Steel Strip Electrolytic Cleaning Line (ECL)

Remove rolling oil and iron fines before annealing. Electrolytic cleaning can be a standalone line or an integrated section of a CAL, selected against surface cleanliness and the downstream product.

  • Entry handling, strip joining and tension control
  • Alkaline spray cleaning and brushing
  • Electrolytic cleaning cells
  • Rinsing, squeezing and drying
  • Bath circulation, filtration and effluent interfaces

Connect it to the product route

For batch annealing, clean the strip in the ECL before the furnace. A CAL can carry its cleaning section inline. Compatible Soft CRC and tinplate schedules can use shared ECL capacity.
