摘要
Abstract
Some steels were sensitive to casting temperature,casting grain size and mechanical properties,such as high manganese steel,using common steel ladles which were for poor insulation performance was difficult to pour many cases by one tundish molten steel.It was easy to form cold ladle because of cooling or casting was insufficient.As a result,a vacuum insulation layer was added to the ladle,it colud reduce the heat absorption of molten steel and external heat loss.The results show that the vacuum-lined steel ladle has better insulation performance.That means compare with the ordinary ladle,it warms up fast when heat up the steel ladle,and tapping temperature can be reduced and save energy.Meanwhile,pouring temperature can be further reduced causes refining the casting grain size to improve the mechanical properties and wear resistance of the casting.The pouring time can be extended because of the molten steel in the ladle is stable.At the same time,it brings good external conditions for pouring operator due to the low temperature of the ladle wall.关键词
