竖炉球团在我国还是一项新工艺、新技术。我国工业生产的竖炉球团厂于66年开始设计,68年首先在济钢、承钢投入生产,其他厂的竖炉也陆续投产。全国至今在12个厂建成23坐竖炉,曾经投入生产的有10坐。各竖炉厂的概况见表1。早在58年大跃进中已着手于竖炉球团工艺的试验研究工作,但由于刘少奇一类骗子 Shaft furnace pellet in our country is still a new technology, new technology. China’s industrial shaft furnace pellet plant began designing in 66, 68 first in Jinan Iron and Steel, Cheng Steel into production, other plants of the shaft furnace are gradually put into operation. The country has so far built 12 shaft furnaces in 12 factories, and 10 have been put into production. The vertical furnace plant in Table 1. As early as 58 years of the Great Leap Forward has started in the shaft furnace pellet process experimental research work, but because of Liu Shaoqi liar
