Detailed introduction
  Steel strip annealing is to uniform steel chemical composition and structure, refine grains, adjust hardness, eliminate internal stress and work hardening, and improve the forming properties of steel.
  Continuous annealing is a process in which a strip is heated to a suitable temperature under a protective atmosphere for a certain period of time, followed by cooling and overaging. In order to improve the surface quality of the strip, an in-line tempering machine is generally designed.
 
  Main features of the unit:
  Material: Strip: Width: 600-1550mm, thickness: 0.2-1.2 (1.5) mm
  Material: cold rolled steel coil SPCC, SPCD, SPCE, in line with JISG3141
  Product quality: CQ, DQ and DDQ, in line with JISG3141
  Unit speed: inlet 0-240mpm, process section, 0-180mpm, exit section 0-240mpm
  Annual production: 100,000-300,000tpy
  Energy-saving mode: waste heat recovery, SUNNY patent
  Continuous annealing furnace: full radiant tube heating (RTF), vertical
  Fuel type: natural gas, liquefied petroleum gas, mixed gas, coke oven gas and electricity
  Welding equipment: narrow lap seam welder
  Degreased form: chemical degreasing + electrolytic degreasing + tertiary water rinsing, vertical or horizontal
  Leveling machine: four-roll wet leveling, maximum rolling force 6,000KN
  Straightening machine: two bends and two corrections (Optional)
  Oiling method: electrostatic oiling
  Electrical control system: SIEMENS or ABB AC variable frequency control system
  Automation instrumentation: SIEMENS or ABB automation control system
 
  The main process flow of the unit:
 
unit
 
  Unwinding → welding → degreasing (alkaline washing + alkali scrubbing + electrolysis + water scrubbing + water washing) → annealing reduction (heating → soaking → rapid cooling → overaging → secondary cooling → water quenching → drying) → leveling → pulling correction → Trimming → inspection → oiling → slitting → coiling.
