Abstract
本发明涉及一种用于制造热冶金学反应器用冷却件的铸模,其中铸模至少局部地接受冷却并衬设有能忍耐高温的材料。本发明还涉及在该铸模中制成的冷却件,在制造过程中,由镍铜合金制成的冷却管被安放在所述冷却件内。
Description
本发明涉及用于制造热冶金学反应器用冷却件的铸模，其中所述铸模至少局部被冷却并衬有可承受高温的材料。本发明还涉及在该铸模中制成的冷却件。
在热冶金学工艺中，反应器的砌砖受到了水冷冷却件的保护，从而因有冷却效果，所以，散发向砌砖表面的热量通过冷却件被传递给水，在这里，与不配置冷却方式的反应器相比，衬材磨损明显减轻。磨损的减轻是由于冷却所谓的由渣和粘在衬材防火面上的其它熔融相构成的自生衬材而造成的。
过去，冷却件是通过两种方法制成的。第一，可以通过砂型铸造来生产部件。在这个方法中，由强导热材料如铜制成的冷却管被安装在砂型中，从而在铸造时，通过管周围的空气或水来进行冷却。要围绕管铸造的部件也是由强导热材料构成的且有利地是由铜构成的。这种加工方法例如已经记载在GB1386645中。这种方法的缺点是，不一致地把起到流道作用的管固定在了周围的铸造材料上，因为管的局部可能完全与围绕其铸造的部件脱离并且管的局部可能完全熔化并因此被破坏。如果在冷却管与围绕它铸成的部件之间形成了非金属复合连接，则传热将不充分。如果管完全熔化，则它将阻止冷却水的流动。铸造材料的铸造性能例如可以通过将一些磷混入铜中来提高，这将改善在管与铸造材料之间形成的金属复合连接，但是这样一来，即便磷加入量很小，铸铜的传热性能(导热率)也明显降低。这种方法的优点可以列举出加工成本比较低以及与尺寸无关。
还次用了一种加工方法，其中成流道形状的玻璃管被装入冷却件的铸模中，所述玻璃管在铸造后破裂，从而在部件内形成流道。
美国专利US4382585描述了另一种被广泛采用的冷却件加工方法，根据这篇文献，部件例如是由轧制铜板而通过机加工出所需槽路而制成的。这种方法的优点是密实坚固的结构和冷却介质如水对部件的良好传热性能。缺点是尺寸有限并且成本高。
现在，已经研制出了一种铸模来代替先前的砂型铸造来制造热冶金学反应器用冷却件。铸模由独立的强导热铜板构成，其中至少一些铜板接受水冷。由于冷却件本身在大多数情况下是铜，所以，铸模的结构板应与铸铜隔绝开，这是通过给铸模内部衬上强导热材料如石墨板而实现的，从而铸模部件本身通过负压被固定到表面上。石墨防止了浇入铸模中的熔液粘在铸模表面上。冷却件铸模有利地配设有一个上型箱，从而可以在屏蔽气氛中完成铸造。在铸造前，冷却水循环所需的且要进入冷却件内部的冷却管被安放到铸模中。管最好是镍铜合金管，因为镍铜合金管的熔点高于围绕它铸造的铜并因此没有管在铸造过程中熔化的危险。
本发明的基本特征将在后续的权利要求书中变得一清二楚。
本发明所述的铸模结构带来了以下优点：
-由于冷却铸模和有石墨衬，形成了致密的细晶化铸件，尤其是在铸模底板。
-铸模结构意味着冷却件形成了光滑表面，这不容易受到腐蚀性熔炼环境的影响。
用作冷却件材料的镍铜合金冷却管有助于将管良好地熔焊到使用的部件上。
可以进一步发展铸模结构，从而它也可以被用于制造被设计用于特殊目的的冷却件。这例如通过给铸模添加石墨或耐火形件来实现，从而成品件的形状明显不同于镀覆件。
借助附图来进一步描述本发明，其中：
图1表示本发明铸模的原理图。
图2以横截面图表示铸模，可以通过该铸模铸造专用冷却件。
图1画出了冷却件铸模1的原理图。该铸模由一个配备了冷却管3的铸模底板2构成。铸模还具有侧壁4、5和端壁，而在图中只画出了后壁6。在图中，只有底板配备了冷却管，但如果需要，侧壁和端壁也可以配备冷却管以便冷却。为了清楚起见，图2省掉了前端壁，尽管它毫无疑问地属于铸模。
铸模内侧衬设有石墨板7。有利地由镍铜合金构成的冷却件冷却管8支承在铸模内。铸模也配备了一个上型箱(未示出)，从而可以使用屏蔽气体来防止要铸造的部件氧化。
可以在图2中看到，异形件9可以被安放在铸模底板上，它们由石墨或一些其它耐火材料构成。通过这些异形件，将冷却件10接触铸模底板2的那一侧11可以被制成所需形状。
