| 中文摘要: |
| 研究了使用天然原料一次合成钙长石轻质耐火砖的可行性。实验表明,将煅烧煤矸石、蓝晶石、硅灰石、苏州土、纯铝酸钙水泥等原料一起混磨至粒径小于320目,用发泡法可以合成出体积密度小于480kg/m3的钙长石轻质耐火砖。此种钙长石轻质耐火砖的最佳煅烧温度为1300℃,最高使用温度为1260℃,常温耐压强度为1.15MPa,抗折强度为0.92MPa,800℃的导热系数为0.17W/mk,1230℃×24h重烧线变化为0.128%. |
| 英文摘要: |
| The possibility of producing anorthite light refractory bricks by Using natural minerals has been studied.The experiment shows that coal gangues,kyanite,wollastonite,Suzhou clay and calcium aluminate cements can make good anorthite light bricks with a foaming method.The raw materials have to be milled to a grain size smaller than 320 meshs.The optimum temperature of sintering is 1,300℃.The classification temperature of this refractory brick is 1,260℃;its cold crushing strength is 1.15MPa,its modulus of rupture is 0.92MPa,its thermal conductivity at 800℃ is 0.17W/m·k,and the liner change after a 1,230℃×24hour reheating is 0.128%. |
