Description

金属熔体取样装置
技术领域
本发明涉及金属熔体取样装置，尤其是熔融铁和熔融铸铁的取样装置，该装置配备有具有入口的样品室，其中该样品室中设置有碲。
背景技术
由专利文献DE 2646539A1中得知这样一种用于测定金属熔体凝固温度的容器，其中该容器底面上设置有粘附的碲层。这种含有难熔材料和产氢材料的混合物会造成碲的延缓释放。这样，碲本身应该会改善倒入容器内的熔体的所谓的白凝固(white solidification)。由专利文献EP 436063B 1中得知，将含有碲的混合物设置在熔融金属取样器的入口的密封盖中。当密封盖被破坏时，流入的熔融金属会将该混合物冲入样品室内。在专利文献US 5948350中披露有类似的装置。
发明内容
本发明基于这样的问题，即：要得到一种使得金属样品在其中可达到最佳白凝固的取样装置。
该问题是通过独立权利要求的技术特征解决的。在从属权利要求中阐明了有利的实施方案。令人惊讶的是，已经表明：与现有技术的教导相反，当把纯碲均匀分布于样品中时，获得了最佳的结果。
这是借助本发明的装置实现的，其中，相对于样品室的容积，该样品室含有0.01g/cm3至0.05g/cm3的碲，并且其中所述碲呈平均粒径为不超过150μm的粉末状，或者其中所述碲呈平均粒径为不超过150μm、且比表面积为0.03m2/g至0.1m2/g的粉末状。
优选的是，样品室含有0.015g/cm3至0.025g/cm3的碲。更为有利的是，其比表面积为0.06m2/g至0.07m2/g。
附图说明
下面，将参照附图并通过实施例对本发明进行描述。在附图中：
图1示出本发明的取样器的剖面；
图2示出白凝固样品的抛光剖面；并且
图3示出未添加碲的常规样品的抛光剖面。
具体实施方式
本发明的取样器具有由型砂制成的主体1，其中样品室2设置在开口内。该开口在取样器的浸没侧被砂体3封闭。样品室2具有环形轮廓，其直径约为35mm且高约为10mm。其底表面分别由金属板4形成，并且位于两个底表面之间的侧表面是由陶瓷环5制成的。
图右侧示出了入口6，其与石英管相连。该石英管由保护盖7封闭。
主体1具有用于常规载体管的连接口8。所述载体管可以由纸板形成。
在样品室2中，设置有约0.2g碲粉末9，相对于该样品室的容积，碲粉末9的设置量为约0.02g/cm3。该粉末通过研磨制得，其平均粒径小于100μm，且比表面积为约0.065m2/g。
由于比表面积和体积或质量相互之间没有直接的关系，因此即使仅满足其中一个条件就已经产生了本发明的有益效果，这显然是由于在熔体进入样品室中时，所述粉末与熔融金属出人意料地混合均匀了，因此本发明的有益效果得以实现。这样便产生了图2中所示的所需的白凝固。相反，当未添加碲时，产生了图3中所示的非均匀的凝固。
