In order to ensure that the gas hot blast stove is checked to see if the equipment in front of the stove meets the acceptance standards, and all types of work can be familiar with the operation, in order to ensure that the front inspection is qualified. Pave the slag ditch, iron hook, and support iron hook, and dry with fire. At the beginning, the furnace has a small amount of iron and poor fluidity, so it is prepared for the small pit. If necessary, make temporary pits.

Check whether the electrical part of the gas hot blast stove is possible, whether the furnace cover is grounded intact, whether the heating element is short-circuited or open. The main iron ditch is poorly handled. In order to prevent poor slag iron activity, the iron storage type is changed to the over-iron type. If the supporting part of the furnace top fan has been transformed into a circulating cooling ^ water cooling ^ structure, please check whether the cold water circulation is normal.

The configuration of the gas hot blast stove is improved, and parts such as induction coils, reactor copper tubes, etc. are added, which reduces losses and can save 30-80 degrees of electrical energy. Increasing the speed of the gas hot air stove can reduce the loss, because during the heating process, the heat dissipation is the same, part of the heat is lost to the air, and the other part is taken away by the cooling water. The faster the speed, the shorter the time and the shorter the heat dissipation time. Therefore, acceleration is an important condition for energy saving.

Burning hole for oxygen, oxygen bag, oxygen tube, broken rod, beater rod, etc. Observe the flame and furnace temperature carefully to prevent high temperature deformation; during operation, manually adjust the air supply volume according to the temperature of the dryer and heating furnace at any time to stabilize the air temperature of the dryer; check the operation of the fan and air supply to avoid An abnormal phenomenon has occurred.


 
The cement and mud of the electric furnace should not be too much, and the iron should be filled. Before opening the furnace to supply air, put the gas duct into the mud jacket, judge whether the taphole mud jacket is ready, unplug the duct, and then dry the taphole mud jacket. Determine whether the sealing material of the hot blast stove cover is intact. Make preparations for auxiliary materials such as blasting mud, trench materials, and thermal insulation materials.

When the energy consumption of gas hot blast stove is large, power measurement is also a method to assist in guiding production operations. Therefore, the production of gas-fired hot-blast stoves should strictly implement the equipment maintenance plan to reduce downtime and maintenance costs and improve production efficiency. During the use of gas-fired hot-blast stoves, the method of "staggered production" can be adopted to divide the energy utilization into several stages, and the stage with high energy consumption is placed in the stage with low electricity consumption.

The method to deal with the cold temperature of the gas hot blast stove: Before operating the gas hot blast stove, reduce the air by about 50% to control the material speed to prevent the furnace temperature from continuing to drop. When the air volume is reduced, a batch of net coke is added, and the coke load is correspondingly reduced. Before discharging the slag, make all efforts to discharge the slag, try to avoid the tuyere pressing and burn through accidents, and wait until the coke reaches the clean coke. Ensure the symmetry of wind pressure and air volume to avoid material collapse and suspension.
