钢材退火用托盘
本专利技术涉及钢材退火工具,特别是钢材退火用托盘。
技术介绍
退火是一种金属热处理工艺,指的是将金属缓慢加热到一定温度,保持足够时间,然后以适宜速度冷却。目的是降低硬度,改善切削加工性;消除残余应力,稳定尺寸,减少变形与裂纹倾向;细化晶粒,调整组织,消除组织缺陷又为后续工序作好准备,故退火是属于半成品热处理,又称预先热处理。现在企业中对一些长条型钢材进行热处理时,一般是将钢材放入炉体辊道上进入炉体进行退火,因钢材在加热过程中会变软,放置在辊道上钢材易变形,不便于钢材的后续工序。
技术实现思路
本专利技术的目的就是针对以上缺点进行改进,提供一种结构简单,制作方便,保证长条型钢材进行热处理时不易变形的钢材退火用托盘。本专利技术钢材退火用托盘,其特征在于:包括有若干个矩形托盘,托盘之间活动连接,所述首端托盘的两条长边及一侧短边上均设有挡边,另一侧短边为敞口,首端托盘后端的各个托盘的两条长边上均设有挡边,两侧短边为敞口,首端托盘的两条长边的挡边尾端设有挂钩,所述首端托盘后端的各个托盘的两条长边的挡边前后两端分别设有挂环和挂钩;所述的每个托盘上均设有减重口和若干 ...
