Two grades of high-alumina brick cover walls are two, and left and right is arranged side by side, and the bottom of two two grades of high-alumina brick cover walls is separately fixed at two magnaliums
On spinelle base；Two grades of high-alumina brick cover walls are formed with two grades of high alumina brick masonries；Two grades of high-alumina brick vaults are arch, its both sides bottom
Portion is separately fixed at the top of two two grades of high-alumina brick cover walls；Two grades of high-alumina brick vaults are formed with two grades of high alumina brick masonries；Two grades
The bottom of high-alumina brick case is fixed on the top of two grades of high-alumina brick vaults；Two grades of high-alumina brick cases are with two grades of high alumina brick masonries
Into；Space between two grades of high-alumina brick cases and two grades of high-alumina brick vaults is consolidated with high alumina castable layer filling, and High-Alumina is poured
Material feeding layer is made of high alumina castable；Aluminum-spinel base, two grades of high-alumina brick cover walls, two grades of high-alumina brick vault threes surround
Cross section is inverted U-shaped high-temperature smoke passage.
The outer top surface and inner top surface of two grades of high-alumina brick vaults described in the utility model are arc.
Two grades of high-alumina brick cases described in the utility model are arc.
Aluminum-spinel substructure height described in the utility model is 50cm.
The utility model compared with prior art, with advantages below and effect：Magnalium matter spinelle refractory degree is high, and lotus is soft
Up to 1650 DEG C of point, alkali resistance flue dust immersion performance is strong；Two grades of High-Alumina bricks belong to neutral resistance to material, do soda acid flue dust immersion performance tool
Good, 1450 DEG C of lotus soft spots tackles 1100 DEG C of high-temperature smokes more than sufficient；It can be seen that, magnalium matter spinelle and two grades of High-Alumina bricks are resistance to
Fiery degree is much higher than Theoretical Design temperature, can greatly prolong service life, dramatically saves on production cost.
It is now that the utility model and prior art use cost and Economic Efficiency is as follows（Prior art can only use 1
Year, the utility model can at least be used 8 years）：
A. use cost compares
Prior art:100 tons × 1100 yuan/ton=110,000 yuan yuan/year of ÷ 1 year=110,000 of clay brick；
The utility model:Aluminum-spinel：20 tons × 2100 yuan/ton=4.2 ten thousand yuan yuan/year of ÷ 8 years=0.525 ten thousand；High alumina
80 tons × 1500 yuan/ton=120,000 yuan yuan/year of ÷ 8 years=1.5 ten thousand of brick；It is total 2.025 ten thousand yuan.
B. economic benefit
The utility model is pressed to be calculated using 8 years, use cost saving=(11-2.025) ten thousand yuan/year × 8 year=71.8 ten thousand yuan.
The annual overhaul of prior art once, takes one month, loses 60,000 tons of stainless steel output, is got profit by stainless steel per ton
500 yuan of meters, economic benefit=60,000 ton/year × 500 yuan/ton × 8 year=240,000,000 yuan the utility model by based on using 8 years,
+ 24,000 ten thousand yuan=24071.8 ten thousand yuan of economic benefit=71.8 ten thousand yuan can be produced.
