摘　　要：介绍电炉加料阀的苛刻使用工况及研制的主要技术难点,包括高温材料和高温耐磨涂层的选择、阀门特殊结构设计、球体和阀座表面的硬化、超硬球体磨削和模拟实际工况的型式试验等。通过对技术难点的攻关,研制的电炉加料阀的各项性能够满足使用工况的要求,并已成功运用在缅甸达贡山镍矿项目。This paper discusses the severe working condition of feeding valve of electrical furnace and main technical development difficulties, including the selection of high temperature materials and hightemperature and wear-resistance coating, the special structure design of the valve, the hardening of the ball and seat surface, the grinding of superhard ball and the type test of simulation of actual working condition. With the breakthrough of technical difficulties mentioned above, the performances of the developed feeding valve of electrical furnace meet the requirements of severe working conditions, then it has been successfully used in the nickel project in Myanmar Dagong Hill.
