摘　　要：利用风淬钢渣和碳纤维复掺制备了导电盲道砖。研究了盲道砖在不同工况下的电热规律。结果发现,在5~30 V直流电压作用下,试件的表面温升值随电压增加而增加。30 V电压作用下,试件表面温升效果最好,并且试件的电阻随温度升高而减小,具有一定的温敏特征。室温条件下,以潮湿河砂作为垫层,30 V电压下,通电180 min时,试件表面的极限温度为42.5℃,通电前后温升达到了20.5℃。化冰实验发现,室温条件下,导电盲道砖能在45 min时融化表面1 cm厚的冰块,与之对应,自然融化相同规格的冰块需要154 min,说明制备的导电盲道砖具有融雪化冰的应用潜力。The conductive blind track brick was prepared by mixing steel slag and carbon fiber.The electrothermal law of the specimen under different working conditions was studied.The results showed that the surface temperature rise of blind track brick increases with the increase of voltage from 5 V to 30 V.Under the action of 30 V voltage,the surface temperature rise effect of the specimen was the best,and the resistance of the specimen decreased with the temperature rise,which had a certain temperature sensitive characteristic.Under the condition of room temperature,wet river sand as cushion,30 V voltage,180 min power on,the limit temperature of the specimen surface was 42.5℃,and the temperature rise before and after the test reached 20.5℃;The deicing experiment showed that the conductive blind track brick can melt the ice 1 cm thick on the surface in 45 min.Correspondingly,it took 154 min to melt the ice of the same specification naturally.It showed that the prepared conductive blind brick has a certain application potential.
