Instantiation：
The size of insulation cover 3 is：3030 × 3300mm,
The tank mouth liner internal diameter of inclusion 1 is：2420 × 2652mm, the size of insulation cover 3 are effectively incubated size,
The tank mouth lining area of inclusion 1 is：A1=3.14*（2.42*2.652）=20.152 ㎡,
The size of black matrix 2 is radiated as shown in Figure 4, if 84 black matrixes of placement, 3 times 2 liang protruded of radiation black matrixes of insulation cover
The area of side is as follows：
A2=3.14*（0.0375+0.0485）* the ㎡ of 0.1543*84=3.5,
A3=3.14*（0.0255+0.0385）* the ㎡ of 0.1543*84=2.6,
No matter baking and thermal insulation when initial stage single flow penetrate rifle device 4, work or middle and later periods heat accumulating type penetrate the alternation of rifle device 5,
Radiation black matrix 2 can effectively put together diffusion, will reflect back into the heat absorption come and reflect back, it can be seen that increase spoke
After penetrating black matrix 2, it is increased to the radiations heat energy of inclusion 1, and the increased percentage of heat flow that insulation cover 3 radiates is：
（3.5+2.6）/20.152=30.27%
Because gas-fired is at 1350 degree or so, heat-conducting system is 0.0915W/ (M.K), much smaller than now insulation cover 3
1.396 ~ 1.536W/ of thermal conductivity factor (M.K) of material.Therefore, insulation cover 3 has radiation black matrix 2 to make outside dispersed heat
It is greatly reduced, effectively heat is maintained in inclusion 1.
Analyzed according to domestic roaster service condition, if penetrating rifle device 4 using single flow the temperature of inclusion 1 can be made to be baked to 1200
It is more than degree；If penetrating rifle device 5 using heat accumulating type the temperature of inclusion 1 can be made to be baked to 1100 degree, bag can be improved after increase radiates black matrix 2
300 ~ 360 degree of 1 Nei Wenduda of body, it can be seen that molten iron in inclusion 1 can be incubated using the utility model, and more preferably to building
Inclusion after building is toasted.
Effect：
1st, baking efficiency is improved
Wuhan Iron and Steel Plant iron-smelter tradition baking combustor efficiency is less than 30%, is toasted using that can make pure heat accumulating type after the utility model
The efficiency of combustion of device is improved to more than 85% by 80%；
2nd, ensure hot-metal insulating, avoid molten iron from condensing
Condense to form 20 lumps by molten iron in T-100t hot-metal bottles in 2016, per 80 tons of tank molten iron, molten iron price 2000
Member calculates its economic benefit：80*20*0.2=320（Wan Yuan）；
3rd, iron bag baking time is shortened
It can be shortened within 72 hours 42 hours by tradition, it is advantageously ensured that production tank.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
