Main features of annealing furnace:
A) to take the three level of waste heat recovery technology, reduce energy consumption.
A heat recovery: each radiation tube with high efficiency heat exchanger, air preheater, the preheating temperature is high.
Two times of waste heat recovery: the use of waste gas by heating the waste heat after the flame retardant air, through the heat exchanger, heating preheating section of the gas preheating strip. In order to achieve the two recovery of waste heat.
Three waste heat recovery: used for washing liquid heating and hot air drying system;
The combustion system of energy-saving pumping drum is popular in today's world.
B) the deviation control, to ensure the stable operation of strip annealing furnace.
Optimization of furnace roll crown has self centering function.
Using the control roller CPC.
C) using tension monitoring system.
Furnace roll tensiometer continuous monitoring, can reduce the annealing furnace with high temperature and high tension caused by thermal buckling phenomenon and low temperature, low tension strip deviation. The system can ensure the normal operation of the unit.
Field instrumentation and process control for d:
All equipment design is considered to be the best control of the process, safe and reliable.
The heating temperature of the steel strip is monitored by the high temperature radiometer. The high temperature radiation meter with water cooling tube and nitrogen purge can reduce the interference of the furnace wall and the measuring head of the cleaning radiometer.
The strip is heated in the furnace, annealing furnace installed analysis instrument, can be real-time monitoring of each furnace, to ensure the stability of product quality and safety equipment.
E) safe operating conditions:
- Electrical or automatic control of the monitoring instrument, air, power supply failure, all the implementation of the restoration to the location of the location.
- top provided with explosion-proof holes
The annealing furnace is provided with a glow heater, which can burn out the residual oxygen in the furnace.

Design basis:
Reference strip 0.62 mm * 1600 mm * 180 MPM = 84.1t/h based on CQ
The heating capacity of the furnace is 0.62 mm * 1600 mm * 180 MPM based on CQ (20 ~ C to 720 C)
The slow cooling capacity of the furnace is 0.62 mm * 1600 mm * 180mpm based on CQ (720 ~ C to 675 C)
The quick cooling capacity of the furnace is 0.62 mm * 1600 mm * 180mpm based on CQ (675 ~ C to 400 C)
The aging treatment capacity of the furnace is 0.62 mm * 1600 mm * 180 MPM based on CQ (400 to 300 degrees C to degrees C).
The final cooling capacity of the furnace is 0.62 mm * 1600 mm * 180 MPM based on CQ (300 ~ C to 120 C).
