Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
1, brick of LZ-75 tall aluminium and the manufacturing technology of many clinker clay brick are similar, different point depends on scale of the grog in burden taller, can be as high as 90 ～ 95 ％ , clinker is in broken before need to classification choose and screening divide iron, firing temperature is higher, if the tall aluminous brick such as Ⅰ , Ⅱ uses channel kiln to burn
The thermal conductivity of magnesia brick (coefficient of thermal conductivity) (Thermal Conductivity) , namely its deliver caloric capacity, express normally with coefficient of thermal conductivity. Thermal conductance expresses to transfer a process in energy in, inside unit time, below unit temperature gradient, the quantity of heat that unit area place passes.
The accuracy of the validity of fireproof material appearance and dimension builds the close sex of body to have immediate effect to electric stove build by laying bricks or stones, and the service life that build by laying bricks or stones builds the close sex of body to deciding build by laying bricks or stones to build system greatly. The brick is seamed be being built in build by laying bricks or stones is the most fragile in body the part with the easiest attaint, with
Al2O3 content is more than a general designation of siliceous aluminous simple fireproof stuff of 48% to pledge for tall aluminium fireproof material. Its finalize the design the product is furnace of hot project kiln namely most the tall aluminous brick that Chang Chong moves. Press Al2O3 content more or less to differentiate, tall aluminous brick can divide for 3 grade: One class: 2 class of Al2O3 75%; : Al2O3
Ball of corundum qualitative accumulation of heat, with high pure AI2O3 small pink is main raw material, mix into is reached into a few clay high pure rare-earth metal oxide, become through high temperature roast. Have the amount that contain iron low, density is big, crystal good, high temperature resistant, fight corrode, intensity stability of tall, thermal shock is good,
G1, g2, g3, g4, g5, g6, g7, g8 clay brick and tall aluminous brick, the firebrick of these a few kinds of model cooperates build by laying bricks or stones to build a circle to need to pass careful consideration. The appearance of these a few kinds of bricks, dimension pursues as follows. Hearth place can divide the cubage with every brick to calculate by bricklaying total volume. Beg
It is new-style that anchorage solid brick says condole hangs brick of brick and anchorage firmware, anchorage solid again involving furnace of kiln of a kind of industry to use roof of electric stove of anchorage solid brick is with the metal condole hangs the support furnace top between brick and firebrick structure. Because of gas of the reactivity inside this furnace and steam divulge, condole of meeting injury metal is hanged
Tall aluminous brick is had apply quality goodly, fireproof degree tall, apply life to grow wait for characteristic, it is the firebrick goods with most wide application of industrial kiln furnace. Tall aluminous brick is used at liner of roof of steely, steel-making, hot-blast stove, electric stove, blast furnace, reverberator, rotary kiln to wait commonly
Magnesia brick (Magnesite Brick) magnesian content is in the 90% above, alkalescent and fireproof material that gives priority to brilliant photograph with Fang Mei stone can be divided commonly for agglomeration magnesia brick (say again firing magnesia brick) combine magnesia brick with chemistry (say not to burn magnesia brick again) two kinds big. Purity and firing temperature is high
Common the influencing factor of the price of tall aluminous brick is very much, tall aluminous brick is in our country to be 4 grade with alumina content cent: Fancy Al2O3 content 90% ; Content of one class Al2O3 75% ; Content of 2 class Al2O3 is 60 ～ 75% ; Content of 3 class Al2O3 is 48 ～ 60% . The content of alumina decided
Pledge Mo Laishi brick calls Molaishi adiabatic firebrick again gently, basically be the fireproof material that gives priority to mine photograph character with siliceous aluminium, have a few good performance, (especially function of high temperature creep) the high aluminous products that is on production of natural raw material is consummate. Brick of Mo Laishi heat preservation, root
1, from the bottom up of construction measure comply with, by in the principle outside coming undertakes, drum bottom reachs convection check interval on when blaze board irrigates Tong by on reach next undertaking. 2, demand of boiler setting air-tightness is high, ash seams full spend a requirement: Red brick not under 85% ; Firebrick not under 90% .
