Degreasing Line

Steel Strip Degreasing Line

During steel strip cold rolling procedures, usually lubricant, palm oil orsimilar artificial synthesized oil will be used as lubricants. This lubricantcould grease a layer of oil film on the surface of steel strip. When thegreased steel strip is annealed in the furnace, due to decomposability of heating,carburization and residues generation shall happen, which will affect steel stripcomposition and the surface cleanness, thus pay a bad influence on the quality ofthe subsequent processing. Our degreasing line is functioned with clean steel stripsurface with chemical and electrochemical methods to satisfy qualityrequirements of the subsequent procedures. Besides, this electrolysisdegreasing unit can release the coils after cold rolling, shear the over-thickrear part of the steel strips, adjust coil weight and recoil with certainsuitable tension force.

OverallConfigurations of the Degreasing Line

◆The degreasing line adopts horizontal arrangement, with recycling systemmounted at the side of transmission, it is convenient for threading,installation, operation and maintenance;

◆Electrolysis cleaning device adopts mediumelectric current density, which is high efficient in degreasing;

◆Recycling system isequipped with automatic control to temperature, liquid level and density;

◆Waterwashing section is comprised of 3 stages, the washing quality of the finished steelstrip is guaranteed by continuous water supply of the water washing box at thelast stage.

◆The brushing height ofthe roller can be adjusted synchronously by the air cylinder;

◆Coilouter diameter and width measuring device is equipped in the entry section torealize automatic coil load.

◆Rollerchange trolley is adopted for brushing roller and squeezing roller in thewashing section to guarantee a fast and convenient roller exchanging;

◆Toguarantee constant tension force at each section and a reliable operation, twotensioning rollers are equipped respectively at the front and rear of theprocessing section.

◆CPCautomatic deviation rectifying device is equipped at the decolier and EPCautomatic centering device to the edge is equipped on the recoiler to guaranteea high-speed stable operation of steel strip and high-quality coiling.
