Normalizing furnace

Normal furnace is a medium - sized industrial kiln, long - shaped. Rolling stock plant forging workshop rolling stock plant forging and metallurgy workshop rolling stock plant forging and metallurgy workshop rolling stock plant forging and metallurgy workshop rolling stock plant rolling stock plant forging and metallurgy workshop rolling stock plant rolling stock plant forging and metallurgy workshop rolling stock plant rolling stock plant forging and metallurgy workshop rolling stock plant rolling stock plant continuous furnace originally used fuel oil sub high speed burner, mainly used for heat treatment after the train axle heating forging, is one of the main equipment.

Advantages of normal furnace

1. Easy to use, suitable for production environment;

2. The temperature in the furnace rises rapidly and the temperature in each section is uniform;

3. The overhaul period of furnace body is guaranteed to be more than five years, and the vulnerable parts such as furnace door and burner are easy to repair.

Normalizing defect

1. High oil consumption, low efficiency and serious environmental pollution;

2. There are many faults caused by pushing steel track, and maintenance is difficult, which affects production;

3. Low degree of automation control and high rejection rate, generally around 12%.

The main factors that affect the normal furnace system work are: the furnace temperature system, the type of fuel, the way of air and gas preheating, the type of metal to be heated, the way of metal loading and discharging, the choice of automatic control system, the choice of furnace material.

Modified normalizing furnace furnace is divided into three areas, into the furnace area of workpiece by pushing machine, heating area, there are on either side of the wall under the staggered arrangement of four burners, orbit by brick build by laying bricks or stones into the arch support, double-side heating of components, to forward is two and three areas - constant temperature area, with highly staggered arrangement in two side wall four burners. The eight burners are all made of low-pressure eddy current burners, with spacer beams between zone 1 and zone 2, and two composite metal heat exchangers on top of the front and rear of the furnace. The furnace walls on both sides, the bottom of the furnace are made of brick structure, the top of the furnace is made of refractory fiber felt, and a high-pressure fan is used to supply both combustion air and smoke ejector air. In the gas main, air main equipped with regulating valve and flow orifice plate, in the ejector main also equipped with regulating valve, at the same time equipped with a set of advanced microcomputer control system, display instruments and protection equipment.
