3 terms and definitions
The following terms and definitions apply to this document.
3.1
Thermal efficiency thermalefficiency
The amount of heat absorbed by the billet is the percentage of the fuel chemical heat supplied to the furnace and the sum of heat from other heat sources.
3.2
Preheater waste heat recovery rate recuperatorheatrecoveryefficiency
Air, gas preheating obtained by the physical heat and into the preheater before the physical heat ratio of flue gas.
3.3
Preheater temperature efficiency recuperatortemperatureefficiency
The preheated air (or gas) temperature is reduced by 20 ° C compared to the temperature at which the flue gas enters the preheater by 20 ° C.
3.4
Push steel furnace bottom than skidhearthrate
The ratio of the total area of the bottom pipe to the bottom of the furnace and the bottom of the furnace.
3.5
The strength of the furnace
Per square meter of steel bottom area per hour of production.
3.6
Heating furnace utilization rate rusting
When a plurality of heating furnaces are arranged in a rolling mill, the output of the single-seat heating furnace will be lower than the rated output due to the mutual interference between the charging and discharging materials.
The actual yield to the rated output ratio is called the furnace utilization.
