Abstract

本发明涉及一种激冷剂，包括如下成分，按重量百分比，碲45%-55%，铝20-30%，钛10%，余量为铁，上述各成分制成0.5-1.5mm的颗粒后均匀混合形成所述激冷剂。本发明提供的激冷剂能促使铁液无论是亚共晶还是过共晶，无论是否经过孕育处理，都能按白口凝固， 在冷却曲线上显示出较长的共晶停歇平台，从而获得准确的CEL，C，Si值。

Description

一种激冷剂
技术领域
本发明涉及一种激冷剂。
背景技术
铸铁是具有共晶转变的铁碳合金, 当铁水倒入热分析样杯后，成份一定的铁液在冷却凝固过程中发生相变释放出结晶潜热，冷却曲线发生变化，得到的冷却曲线上的特征值是符合一定规律的, 因此可根据冷却曲线上的特征值来确定铸铁的碳当量、含碳量和含硅量。热分析样杯就是利用这一热效应，通过测定凝固过程中冷却曲线初晶温度和共晶温度点，用计算机归纳分析铸铁的CEL，C，Si以及相关特性。
灰铸铁在凝固过程中，受铁液孕育状况及结晶条件的影响，难以找到准确的共晶温度。此外，共晶反应时，由于铁液放出结晶潜热，导致共晶反应在某一温度区间内进行。
发明内容
本发明目的在于解决上述问题，提供了一种激冷剂，具体由以下技术方案实现：
一种激冷剂，包括如下成分，按重量百分比，碲45%-55%，铝20-30%，钛10%，余量为铁，上述各成分制成0.5-1.5mm的颗粒后均匀混合形成所述激冷剂。
所述的激冷剂，其进一步设计在于包括如下成分，按重量百分比，碲50%，铝30%，铁10%，钛10%。
本发明提供的激冷剂能促使铁液无论是亚共晶还是过共晶，无论是否经过孕育处理，都能按白口凝固， 在冷却曲线上显示出较长的共晶停歇平台，从而获得准确的CEL，C，Si值。
附图说明
图1为在测量样杯中添加本发明后的测量结果与化学分析结果的误差比对图。
具体实施方式
以下结合说明书附图以及实施例对本发明进行进一步说明。
实施例1，该激冷剂包括如下成分，按重量百分比，碲45%，铝20%，钛10%，铁25%，上述各成分制成0.5-1.5mm的颗粒后均匀混合形成所述激冷剂。
实施例2，该激冷剂包括如下成分，按重量百分比，碲55%，铝30%，钛10%，铁5%，上述各成分制成0.5-1.5mm的颗粒后均匀混合形成所述激冷剂。
实施例3，该激冷剂包括如下成分，按重量百分比，碲50%，铝30%，钛10%，铁10%，上述各成分制成0.5-1.5mm的颗粒后均匀混合形成所述激冷剂。
将上述激冷剂均匀涂抹在热分析样杯的底部即可对热分析样杯内加入铁液进行测量。
如图1所示，采用了实施例3所提供的激冷剂对不同成分的铁液分别两侧检测后，CE，C，Si值的数据及其与同一铁液化学分析后的结果比对，可以看出使用被发明后的测量结果准确度较高，且测量稳定性较好。
