摘　　要：我公司应用数控、冗余系统、气氛保护、恒熔速控制等多项先进技术,开发了数控型三相保护气氛电渣熔铸炉[1]。该设备运行可靠,位置控制精度极高,工艺执行的再现性更强,为电渣熔铸提供更优的凝固条件。设备生产过程中产品质量合格率100%,产品的气体含量及夹杂物指标都大幅度优于普通电渣锭。此设备的开发成功可以为我国生产高质量大型电渣锭提供可靠的技术保障。Numerical control, redundancy system, atmosphere protection, constant melting speed control and other advanced technologies have been used to develop the numerical control electroslag casting furnace with three-phase atmosphere protection. The equipment has the characteristics of reliable operation, position control with high precision and better reproducibility of process execution, which provide better solidification conditions for electroslag casting. The qualified rate of the product is 100% during manufacturing, and the gas content and inclusion of the product are much better than that of the common electroslag ingot. The successful development of this equipment can provide a reli- able technical support for the production of high quality large electroslag ingot in China.
