Description

一种侧底注控制浇钢的中频感应电炉 技术领域
本发明专利涉及一种中频感应电炉结构，尤其涉及一种侧底注控制浇钢的中频感应电炉结构。
 背景技术
中频感应电炉主要用于熔炼行业，使铁磁材料内部通过感应方式产生涡流，达到加热熔化的目的，主要由炉壳、感应圈，与预制或打结炉衬材料组成。传统的感应电炉在顶部设置浇钢口，熔化的钢液通过浇钢口，采用减速电机与液压倾转方式浇钢。
中频炉用在铸造行业时，主要负责熔化钢水，并将高温钢水浇到钢水包或浇注机的浇包中，通过钢水包或浇注机进行二次浇筑铸件。为保证钢水的浇筑温度不能偏低，使用前需要对浇包进行预热，并且适时补入高温钢水，防止包内钢水温度过低，然后通过塞杆控制，或直接从浇注机水口通过倾倒的方式浇筑铸件。
中频炉用在其他行业，如非晶或纳米晶喷带行业，同样需要将熔化的钢水浇入中间包或者稳流包内，通过中间包底部塞杆控制钢水流量进行喷带。
因此在钢水由中频炉向浇注机的浇包或中间包转移的过程中，不可避免的会产生钢水热量流失，需要定时补入钢水，或采取辅助加热保温措施，这造成了极大的能量损失。
