辽宁电厂灰有良好的隔热性能,可大幅度降低绝热板的导热系数。以电厂灰为骨料的轻质绝热板的导热系数为0.07～0.1W/(m·℃),耐火度1350～1410℃。轻质绝热板钢锭轧制的钢坯切头低倍组织致密,偏析甚轻。钢锭头部一次缩孔深度≤4.2%,故可减小帽部容积0.7～1%,提高钢锭成坯率0.8～1%,每年可为鞍钢创造经济效益276万元。 Liaoning power plant ash has a good thermal insulation properties, can greatly reduce the thermal conductivity of insulation panels. The thermal insulation coefficient of light weight thermal insulation board with power plant ash as aggregate is 0.07 ~ 0.1W / (m · ℃) and the fire resistance is 1350 ~ 1410 ℃. Lightweight insulation panels slab rolled billet cut compact microstructure, segregation is very light. Once the ingot head shrinkage depth ≤ 4.2%, it can reduce the cap volume of 0.7 to 1%, improve ingot ingot ingot rate of 0.8 to 1%, an annual economic benefit of 2.27 million yuan for the Ansteel.
