发明内容
针对上述缺陷，本发明的目的在于提供一种结构简单，阻滞力小，射流强度高，冷却效果好，冷却成本低的一种轧机层流均匀冷却喷嘴。
为此本发明所采用的技术方案是：
包括喷嘴和流道接管，所述喷嘴后端固定安装在流道接管的前端，喷嘴通道与流道接管通道相联通，所述喷嘴通道分为后通道、过渡通道和喷射通道，后通道的内径大于喷射通道的直径，所述过渡通道为锥形通道，喷嘴通道内径与流道接管通道内径相同。
进一步，所述喷嘴通道后端内设有台阶，所述流道接管的前端位于台阶处。
进一步，所述喷嘴通道的内壁与流道接管通道的内壁均为光滑表面。
本发明的优点是：
本发明结构简单，流道阻滞力小，射流强度高，冷却效果好，从而降低了冷却成本。
附图说明
图1是本发明的结构示意图。
图中1是喷嘴、2是流道接管、3是后通道、4是过渡通道、5是喷射通道。
具体实施方式
一种轧机层流均匀冷却喷嘴，包括喷嘴1和流道接管2，所述喷嘴1后端固定安装在流道接管2的前端，喷嘴通道与流道接管通道相联通，所述喷嘴通道分为后通道3、过渡通道4和喷射通道5，后通道3的内径大于喷射通道5的直径，所述过渡通道4为锥形通道，喷嘴通道内径与流道接管通道内径相同；所述喷嘴通道后端内设有台阶，所述流道接管的前端位于台阶处；所述喷嘴通道的内壁与流道接管通道的内壁均为光滑表面。
