Description
Technical field
The utility model patent is related to a kind of heating furnace regenerator honeycomb ceramics, especially a kind of efficient heating furnace accumulation of heat
Room honeycomb ceramics.
Background technology
For Two-cuff Technique room heating furnace large-scale application in all kinds steel rolling mill, the characteristics of its is maximum is exactly energy-saving efficiency height,
It is easy to operate, it can significantly reduce the required power and cost of steel.
The calorific capacity of Jiangxi steel mill blast furnace gas is about 3135KJ/Nm3, and caloric value is relatively low, and theoretical temperature combustion is about
1300 DEG C, about 900 DEG C of actual combustion temperature, therefore simple burning blast furnace gas can not meet needed for heating furnace normal heating steel billet
More than 1700 DEG C of theoretical temperature combustion, 1250 DEG C of requirements above of actual combustion temperature, Two-cuff Technique heating furnace just solves this
Problem.
After the technical principle of Two-cuff Technique heating furnace preheats heat storage by the hot waste gas to discharge out of the furnace, changed by commutator
To, then the heat preheating cooled coal gas that high-temperature thermal storage body is absorbed and cold combustion air, make the coal gas after preheating, combustion air temperature
Reach more than 1000 DEG C, while waste gas discharge temperature is less than 170 DEG C.The physical thermal that heating gas and hot-air are brought into, makes coal gas
Theoretical temperature combustion bring up to more than 1800 DEG C, actual combustion temperature bring up to more than 1300 DEG C, meet production requirement, realizing
While heating furnace saves on a large scale, also low combustion value furnace gas are made to be fully utilized.
Because traditional honeycomb body structure is single, bulk density is small, covet heat exchange area, cause honeycomb ceramics accumulation of heat
Ability, compression strength, refractoriness, lotus softening temperature, thermal shock resistance is insufficient, and honeycomb ceramics produces extruding and become in use
Shape, most of regenerator top layer form cavity, exhaust gas temperature is reached 300-500 DEG C, and smoke evacuation system device damage is serious, and
In, lower floor's honeycomb ceramics cause its poor air permeability because of crimp, empty, coal gas is obstructed when passing through honeycomb ceramics, and fluid distrbution is uneven,
Empty, gas preheating temperature is difficult to reach ideal state so that the low blast furnace gas of calorific value is theoretical during burning
Ignition temperature is affected, and operative employee can only increase coal gas, air mass flow, so cause coal again to ensure normal rhythm of production
Gas consumption is higher.Therefore, heat storage is improved, seeks a kind of more scientific combination and just turns into a urgent problem to be solved.
