Level of state of brick of low creep tall aluminium

The raw material of tall aluminous brick becomes low creep via figuration and calcination. Hear resistance is tall, fireproof degree control in 1770 ℃ . The sex that fight broken bits is pretty good. Heating furnace of puddling of wall of build by laying bricks or stones of in order to, furnace of sandwich glass dissolve, the liner that concrete answers converter to wait, this commodity has decrescent of tall squirm. Fight adhere sex strong, thermal shock dependability is good wait for an advantage, applicable big, medium or small hot-blast stove.

Of tall aluminous brick fireproof degree mix than clay brick of half silica brick fireproof degree must tall, amount to 1750—1790 ℃ , vest in tall Ji is fireproof insulation material.

The Al2O3 in tall metal aluminium is tall, miscellaneous tone is little, the vitreous body that produces Yi Rong is little, accordingly load molten is spent taller than clay brick, but because Molaishi writtens guarantee crystal did not produce beehive record, molten spends reason load to still did not have silica brick tall.

The Al2O3 in brick of low creep tall aluminium is more, press close to turns fireproof insulation material at neuter, can resist acerbity basic slag and slant of alkaline broken bits corrode, because amid contains SiO2, because this is fought,slant the head of a place of strategic importance that the working ability of alkaline broken bits uses than all, water place brick.

Apply to blast furnace of puddling of wall of build by laying bricks or stones, hot-blast stove, heating furnace roof, blast furnace, reverberator, the line in machinery. Besides, tall aluminous brick uses style heat generally store brick of hot type pane, irrigate build a department

The working ability that fights acid slag is some weaker.

1, Gao He is soft tall aluminous firebrick

 Gao He is soft tall aluminous brick and general tall aluminous brick is comparative, help advance somebody's career matrix mixes partly bond one share is different: Help advance somebody's career matrix is divided partly add concentrate of on 3 stone beyond, the organic chemistry after according to is burned forms the fundamental theory of Mo Laishi of press close to, guided effectively tall aluminous raw material, wait like fireproof pink, tall aluminous fireproof pink; Bond chooses clay of high quality ball to wait, inspect sort different choose different clay compound model bond, or it is Mo Laishi bond. Narrate means according to place, the load molten of tall aluminous brick is spent can promote 50~70 ℃ fluctuation.

2, firebrick of low creep tall aluminium

 The basis chooses spoken parts in an opera not balanced report will promote tall aluminous brick fight creep character. Spend a state according to the applied of kiln furnace namely, helping advance somebody's career on 3 stone are added in matrix mineral, active ferric oxide, make help advance somebody's career of matrix form press close to or be Molaishi is formed thoroughly, because help advance somebody's career of matrix not come petrifaction, will promote the Molaishi of raw material water content eventually, reduce sandwich glass photograph to contain in, and mechanical, thermodynamic character is beneficial to Molaishi's splendid structure the promotion of character of raw material tall . To make help advance somebody's career matrix not comes thoroughly petrifaction, operate Al2O3/SiO2 is important. Tall aluminous brick applies low creep to wait for adiabatic kiln furnace at blast furnace of hot-blast stove, puddling in the center.

3, phosphate combines tall aluminous brick

 The brick should spend special grade with high density or phosphate combines tall aluminium is one Ji grog of tall aluminous aluminous cement is crucial raw material, phosphatic aqueous solution or phosphoric acid aluminous aqueous solution are bond, after all previous presses figuration via doing law plane partly, at 400~600 ℃ tone is handled character and the organic chemistry of make it combines firebrick. Its vest in does not bake bricks, furl of the handicraft in using whole process to prevent to be in is very big, must guide normally in condiment add lukewarm expansile raw material, wait like La Pinshi, silica. As tall as the fire that china combines aluminous brick is comparative, its are fought break away from character stronger, but of its load molten is spent inferior, fight corrode character weaker, the electric frit pipe fitting that consequently sluggish wants to add grain fireproof, Molaishi, help advance somebody's career in order to strengthen matrix. Phosphate combines tall aluminous brick to apply wait for kiln furnace position at cement rotary kiln, heating furnace top.
