采用碱性平炉加 ESR 法生产高强韧管坯

BASIC OPEN-HEARTH FURNACE+ESR PROCESS ADOPTED FOR PRODUCTION OF TUBE BLOOM WITH HIGH STRENGTH AND TOUGHNESS

采用碱性平炉＋ＥＳＲ（电渣重熔）法生产高强韧管坯，能完全满足管坯的各项技术要求，各项理化检测结果与采用碱性平炉＋真空除气＋ＥＳＲ法生产的同类管坯水平基本相当。

Adopting the basic open-hearth furnace+ESR process for production of tube blooms with high strength and toughness can meet all the requirements for tube bloom .The tube bloom made by this method has given out the same physical and chemical test results as that made by basic open-hearth furnace +vacuum degassing process+ESR process.
