The results show that the distributions of the surface heat fl ow density and temperature around tube billets are relative.
计算结果表明，管坯表面热流密度沿周向分布的不均匀性造成了管坯温度沿周向分布不均。
The world steel pipe market does not show a good situation but the horizontal continuous casting technology for tube billets has been successfully developed.
世界钢管市场并不景气。水平连铸的管坯生产技术已经成熟。
