【技术实现步骤摘要】
一种钢管退火炉
本技术涉及一种钢管退火炉。
技术介绍
现有技术中,经钢管退火炉退火的钢管还需要进行喷淋降温,喷淋用的水及降温产生的水蒸气被直接排除,造成大量的水资源浪费,且该高热水蒸气中所含有的大量热量也被浪费。
技术实现思路
本技术目的在于克服上述现有技术的不足,提供一种更加环保节能的钢管退火炉。本技术的技术方案是:一种钢管退火炉,包括设有托辊的架体,所述架体包括预热区、加热区和冷却区,所述预热区的下方设有一密闭的蒸汽箱,所述加热区和冷却区的下方设有一水箱,所述蒸汽箱和所述水箱通过连接管相连接,所述预热区和所述加热区上还设有一换热板,所述换热板与所述架体相焊接并紧贴所述托辊设置,所述蒸汽箱的顶部和部分所述水箱与换热板相抵接,该与所述水箱相接触的换热板形成半包式水箱盖,所述加热区上设有一炉体,所述冷却区上设有一喷淋通道,所述喷淋通道的顶部设有一吸风机,所述吸风机通过风管与所述蒸汽箱相连接,所述水箱内还设有一水泵,所述水泵通过水管与所述喷淋通道内的喷淋管相连接。进一步地,所述蒸汽箱底部向水箱方向倾斜向下设置。进一步地,所述连接管的出口位于所述水箱的底部。进一步地,所述水箱上 ...
