Abstract
测量液体熔池(1)的高度的测量杆(2)被冷却,但是装备一实心接头(5)以便在插入到该熔池(1)并且测量熔池(1)的压力的测量气体的开口(7)的前面,该熔池没有固化的危险。
Description
技术领域
本发明为熔融液体熔池的高度的测量杆。
背景技术
这样的杆用于评价在熔炉中难于观测的非常热的材料熔池的高度。该测量在于将固定流量的气体通过使该气体流入该测量杆的导管注入到液体熔池中,在液体熔池中该测量杆的下自由端开口,该测量还在于测量必须对该气体施加的压力,以便使气体以所期望的流量注射。
如果熔池温度太高,则将出现测量杆的一个限制,即在某些玻璃化的应用中就如此,因为构成该测量杆的通常的金属材料失去其耐高温的能力。另外,诸如含有硫酸盐,氯化物或者钼的某些液体熔池特别具有腐蚀性。因此经常要替换该测量杆。
发明内容
本发明的目标是改进这样的测量高度的测量杆的结构,即使测量杆可以抵抗液体熔池,该液体熔池使得通常的该测量杆处于非常恶劣的条件中。
所考虑的解决办法在于通过冷却液体流动的内部管路冷却该测量杆。对于躲避腐蚀和防止抵抗力的损失来说,该方法是有效的,由于不可能从测量杆喷射气体,但是必须防止在该气体导管的出口处导致熔池的固化。而在熔融熔池和非常冷的冷却剂之间的热量的转换产生了靠近该测量杆的熔融熔池的极度冷却。
本发明提供一种测量熔融的液体熔池的高度的测量杆,包括一围绕冷却液体的圆筒形外部外壳,一沿外部外壳的轴线延伸的气体注射导管,该导管用于向液体熔池中注射气体,所述的圆筒形外部外壳封闭所述导管,其特征在于,在该测量杆的自由端上有接头,该接头比外部外壳厚并且是实心,所述外部外壳在所述接头处结束,所述气体注射导管穿过所述接头,并以一个开口结束;所述的测量杆还包括一套管,该套管与所述外部外壳同心且将所述外壳分成冷却液体的供给管道和排出管道,冷却液体的供给系统和排放系统分别在该套管和该外壳的顶部。
在本文中提出了用于满足这些要求、该高度的测量杆改进了的结构,包括一在该测量杆的一自由端向液体熔池中注射气体的导管,和以新颖的方式包括一环绕冷却液体管道的外部外壳,和一具有自由端的接头,该接头比横向外壳厚并且为实心的。该厚的和实心的接头局部降低了热量的传递并且帮助保持在接头之前的该熔池具有比环绕该横向外壳的熔池具有更高的温度。这个设计可以保持围绕该接头的自由端的熔池在液体状态,不是特别粘并且因此保持以期望的流量注入测量高度的气体。
优选地,该外壳为金属制成,并且包括与其共中心的、且使一冷却液体供给管道与一冷却液体排出管道分开的套管,该接头具有一个在一具体实施例中为35毫米的配合的厚度,更广泛地说为几个毫米厚度,冷却液体具有一控制流量以便在该接头之前冷却具有略微高于固化温度(1000℃)的温度的液体熔池。
具体实施方式
现在将通过附图详细描述本发明。
测量杆2插入其中的熔融熔池1可以为玻璃化的在高温下具有腐蚀性的产品。本申请人已经研发了一种称为冷却熔炉技术,其中将被玻璃化的产品不是通过容纳所述将被玻璃化的产品的熔炉被加热,而是通过电磁感应现象进行加热,同时该熔炉被冷却并且被不具有腐蚀性的该熔池材料的固化层覆盖。本发明通常将发现用于这样的冷却熔炉中,但是并不排除其它的应用。
该测量杆2包括一在一具有该测量杆2的自由端的接头5上结束的圆筒形外部外壳4,一沿外壳4的轴线延伸,穿过该接头并且以一个开口7结束的气体注射导管6,和一在该外壳4和导管6中间并且与它们平行的套管,该套管在距该接头一些距离处终止。该接头5被配合在该外壳4的端部中(如图所示)或者延长该接头。冷却液体的供给和排放管道系统9和10分别在该套管8和该外壳4的顶部。一些冷却液体通过该套管8流向该接头5,在该接头前面冷却液体离开该套管8以便开始在该套管和外壳4之间产生对流循环直到导管10为止。
该外壳4较薄以便该测量杆2不会太重,而该接头5为实心的并且较厚,其厚度(或者高度)为例如35毫米,但是选择该厚度用来获得该熔融熔池的一足够高的温度,该温度足够用于允许喷射射由于熔池的充足的流动性导致测量所必须的气体流量,但是该温度也需要足够的低,以便能保证该测量杆2的端部的良好的机械性能和对腐蚀的稳定性。
在熔融材料的约1200℃-1300℃的熔池并且由例如铬镍铁合金金属材料构成一测量杆的情况下,该测量杆插入大约0.5米深度,使用20℃水流以便提取出5.3KW的热量;沿着该外壳4获得该熔池大约冷却600℃,因此固化了通常的熔池。然而,尽管该冷却喷射指向该外壳,由于该接头5的厚度而受到更温和的冷却:在接头5的下表面或者自由表面11上温度为1000℃,以至于熔池1在此处保持液体并且没有堵塞该开口7。该熔池1的高温腐蚀性较小。只要该熔池1位于该接头5的前面,则该接头5的稍微大一些的冷却是可能的。
