镁质中间包绝热板的研制

Development of Magnesitel Heat-Insulating Board for Pouring Basket

介绍一种新型隔热耐火材料，该板用ＭｇＯ＞９５％的烧结镁砂和Ａ１２Ｏ３＞３８％的漂珠为主要原料，以及适量的纤维、结合剂、添加剂研制出的体积密度１．４６ｇ／ｃｍ３，导热系数０．４６Ｗ／ｍ·Ｋ，抗折强度６ＭＰａ的镁质绝热板。

A new kind of heat-insulating refraltory was introduced in this paper.using fired magnesia (MgO>95% ) and light pearl (Al2O3>38%)as main materials, adding appropriate amount of fibres ,binders and additives ,the magnesite heat-insulating board was developed. The bulk density of the board is 1.46 g/cm3,condaetive coefficent is 0. 46 W/(m ·K) and crashing strength is 6 MPa.
