Excellent Annealing Pickling Line with good price for hot-rolled SS strip

Annealing treatment is one of the important procedures during steel strip cold rolling production procedure. The annealing is purposed to remove the inner rolling stress of steel strips, improve mechanical property and clean the surface of steel strips. Annealing equipments can be categorized into bell type annealing furnace and continuous annealing furnace. Our company usually undertakes continuous annealing furnace projects.

Furnace for annealing of stainless steel strip
Through permanent development and decades of experience, JJRS furnace technology for annealing and pickling lines (APL) has become one of the leading products in the market. We offer design, building, and erecting of new furnaces, as well as rebuild of existing systems. Furnaces for annealing and pickling lines for hot-rolled and cold-rolled stainless strip A wide range of stainless steel strip can be processed in these furnace types.

Product description
Typical JJRS design concepts have been incorporated successfully into stainless steel processing lines:

Furnace “roll stands”, each comprising a minimum of two strip support rolls to allow quick roll changeover by rotating the roll-carrying frame without stopping the line
Strip cooling by means of a flexible, freely selectable system with air cooling, water spraying, mist cooling, and combinations thereof, arranged for operator selection or the process automation system
Integrated wet air scrubbing in the cooling section to remove dust and scale from the spent cooling air
Recipe-type control for automatic adjustment of furnace settings according to material and process requirements
Horizontal catenary type of annealing furnace
Finished coils

New design concepts for furnaces include the latest developments in combustion technology, with flexibility in selecting components for optimum efficiencies, low emissions, high productivity, and reduced maintenance. All cost-saving aspects are taken into account, as are environmental regulations. We are committed to permanent new developments and trouble-free commissioning of the furnaces.
