Basis of fast aluminous fireproof ball oxidizes thirdly 2 aluminium (of the how many difference of Al2O3) content, often apply currently have 48% , 55% , 60% , 65% , 73% , of 75% content, return those who have higher content above to be attributed to corundum to turn of course.
According to content how many 55 say below be able to bear or endure for clay bolide, it is a kind of neuter and fireproof material, by aluminous alumina or other alumina content more expensive stock is made form model fire and become. Have thermal stability tall, fireproof temperature is controlled in 1700°C, use at the liner of electric stove of rotary kiln of vitreous forge, cement, steel-making. Of course still a few have Gao He the tall aluminous clay of soft, low creep, small air hole is fireproof ball.
1. hot-blast stove uses fireproof ball
2.Fill uses silicon aluminous ball
3. activator carrier and adsorption use active ball
4. converter uses the ball that block broken bits
5. alumina is hollow ball
6. magnalium ball
Ball of 7. zirconium corundum
8. corundum is fireproof ball
Intensity of normal temperature compression is to show normal temperature leaves data unit area can susceptive is the biggest pressure, the handkerchief that use million (MPa) expresses, namely S=P/A
Intensity of compression of normal temperature of sample of the S—— in type, MPa;
The total pressure that P—— sample destroys, n;
Area of A—— sample press press, mm2.
The intensity of normal temperature compression of fireproof ball is index of a of material main technique. Although be in the common device that heat up labour dead load of susceptive of fireproof ball place is not big, do not exceed 0.1 ～ 0.2MPa commonly. Except be being carried and build by laying bricks or stones is built undeserved, make material suffers bump and squash consequently likelihood outside damaged, because the normal temperature compression of material is strong,spend rarely inferior and destroy.
The strength of normal temperature compression that fireproof ball all provides in active standard not under 15000N/ ball, because the intensity of normal temperature compression of fireproof ball is the parameter that its organize a structure,basically be. And of fireproof ball structure those who form all sorts of craft elements in getting material preparation course restrict, if the feature of raw material reachs the union between burden comparing, grain size and grading and grain, shape method and agglomeration condition, have main effect to the microstructure of material.
Accordingly, intensity of normal temperature compression is to examine the reliable method of active craft state. Additional, the intensity of normal temperature compression that passes data but indirect ground assess is other and mechanical the actor bad of property, good wearability and be able to bear or endure bump a gender to wait to with its intensity of higher normal temperature compression answers relatively.
Fireproof ball is with industry alumina and fireproof kaolin are main raw material, make via scientific recipe, figuration and high temperature to calcine. Fireproof porcelain ball divides common and fireproof ball and fast aluminous fireproof ball, common and fireproof ball is applied to vitriolic the converter with fertilizer industry and commutation furnace, the hot-blast stove that fast aluminous fireproof ball applies to the industry such as urea, iron and steel, heat the equipment such as commutation furnace.
