侵蚀性熔渣

Specimens of the SBCB with different graphitizing degree were obtained in laboratory. Effects of graphitizing degree on the properties of the SBCB, including structure, thermal conductivity, thermal expansivity, resistance to thermal shock, resistance to erosion of molten iron and slag, were studied respectively.

在实验室制备了不同石墨化度的自焙碳块，并研究了石墨化度对自焙碳块的结构性质、高温冶金性能(包括恒压比热容、热扩散率、导热性、热膨胀性、抗热震性)、抗铁水和熔渣侵蚀性能及铁水渗透的影响。

The columniform samples are made with the pressure of 150?MPa that contain graphite,Al 2O 3,SiO 2 and MgO powder.With samples heated at 1?420?℃,1?500?℃ and 1?600?℃ for 4 hours,MgAlON and 21R-AlN Sialon are synthesized by carbothermal reduction nitridation in the sample,MgAlON and 21R-AlN Sialon occure at 1?420?℃.With tempreture rising to 1?600?℃,MgAlON and 21R-AlN Sialon are increasing.

与高温氧化物相比，碳由于熔点高，热膨胀系数小，导热性好，热稳定性和化学稳定性好，不易被液态金属和熔渣润湿等特点，而成为优质耐火原料，使耐火材料在抗熔渣侵蚀和抗热震等性能方面得到质的飞跃。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
