耐火材料

It is an ideal filler for high-temperature furnaces and and excellent aggregate of light weight castable refractory.

是高温炉的理想隔热填充料，亦是高温轻质耐火浇注料的优质骨料，是优良的耐高温，隔热节能的耐火材料。

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。

近年来，一大批先进仪器在耐火材料行业和科技部门

Steelmaking Plant can be reduced to 20ppm by increasing argon flow of RH degasser and controlling vacuity According to the above results, the main efforts to develop IF steels have been made at No 3 Steelmaking Plant.

研究结果表明：钢水增碳主要在大包中发生，影响钢水增碳的主要因素是钢液与包壁接触面积与钢水体积之比，在高温下，耐火材料中CO的压力和钢水中Als的含量对钢水增碳也有一定的影响；钢水脱氧后将增硅，钢水的增硅量主要受大包渣的碱度、中包绝热板材料和中包保护渣碱度的影响；通过增大RH真空处理装置的氩气流量和控制真空度，能将三炼钢厂大包钢水的碳含量降到20ppm左右。

The results showed that three reasons caused the failure of the fibre materials:1the fibre materials transforming into powder which was caused by the precipitation of mullite at high temperatures;2cracking and spalling of the refractory coating and refractory fibre felt;3low strength of the refractory fibre flet.

结果表明：硅酸铝质耐火纤维在高温下析出莫来石晶体导致纤维材料的粉化，耐火涂层和耐火纤维毡的开裂、剥离脱落，耐火纤维毡强度很低是导致纤维材料失效的3个主要机理。研究结果为新型耐火材料的研制或改进提供了重要依据。

Opposite to normal phenol resins the bonding carbon derived from catalytic activated resin is of graphitic structures.

近来人们成功开发了1种催化活化树脂作为含碳耐火材料的结合剂。
