The hydrogen-removal activity(HRA) of Pd-Al_2O_3, Pt-Al_2O_3, and Pd-Pt-Al_2O_3 catalysts was studied. It was found that the HRA and the resistance to S or CO of Pd-Pt-Al_2O_3 bimetallic catalyst were higher than that of Pd-Al_2O_3 and Pt-Al_2O_3 monometallic catalysts. The stability and industrial tests showed that the Pd-Pt-Al_2O_3 bimetallic catalyst had good stability and performance in industrial applications. The surface properties of catalysts wcre characterized by TEM, TPR, IR, and ESCA,...

The hydrogen-removal activity(HRA) of Pd-Al_2O_3, Pt-Al_2O_3, and Pd-Pt-Al_2O_3 catalysts was studied. It was found that the HRA and the resistance to S or CO of Pd-Pt-Al_2O_3 bimetallic catalyst were higher than that of Pd-Al_2O_3 and Pt-Al_2O_3 monometallic catalysts. The stability and industrial tests showed that the Pd-Pt-Al_2O_3 bimetallic catalyst had good stability and performance in industrial applications. The surface properties of catalysts wcre characterized by TEM, TPR, IR, and ESCA, It was observed that the surface properties of Pd-Pt-Al_2O_3 bimetallic catalyst were different from that of Pd-Al_2O_3 and Pt-Al_2O_3 monometallic catalysts. It seems that there may be some interaction between the two metals in the bimetallic catalyst with the formation of a new phase of metal cluster.

研究了Pd-Al_2O_3,Pt-Al_2O_3,Pd-Pt-Al_2O_3催化剂的除氢活性。试验结果表明,Pd-Pt-Al_2O_3双金属催化剂的除氢活性,抗硫性和抗CO性能较Pd-Al_2O_3,Pt-Al_2O_3单金属催化剂好。稳定性试验和工业试验表明,Pd-Pt-Al_2O_3双金属催化剂具有良好的稳定性和工业应用效果。采用TEM,TPR,IR和ESCA对催化剂表面性质进行研究的结果表明,Pd-Pb-Al_2O_3双金属催化剂的表面性质和Pd-Al_2O_3,Pt-Al_2O_3单金属催化剂的不同。Pd-Pb-Al_2O_3双金属催化剂中两种金属之间可能发生相互作用并形成金属簇的新相。

This paper describes the prescription design of the low hydrogen type basic electrode which is manufactured with screw type extrusion coater. It is pointed out in paper that the plastic material, elastic material and slipping agent should be introduced into the prescription to make coating possess the smear ability. At the same time, the welding metallurgical hydrogen removal capacity of elec-trode itslf must be sufficiently effective to actively eliminate the phenomenon of increasing hydrogen which is brought about by improving the smearing properties of coating.

本文着重论述了以螺旋机为生产手段的碱性低氢焊条的配方设计.提出了在配方中引进塑性、弹性和滑性材料,从根本上解决涂料可涂敷性的同时,必须充分提高焊条自身的焊接冶金除氢能力,积极消除因改善涂敷性能而导致的增氢现象.

This paper deals with the advantages of applying multiple hydrogen removal treatments, i.e. slab hot stacking in couple with the molten steel vacuum degassing, instead of charging rolled rails into slow cooling pit, refered to the experiences of foreign rail steel manufactures. The special phenomena of less or even no hydrogen flake occurrence in the hot saw rail specimens from China plateau steel plants, because there is low hydrogen content in molten steel, are discussed.

本文参照国外各钢厂的经验综合论述了将重轨除氢工艺从成品轨在缓冷坑除氢前移到实行低氢冶炼或炉后真空处理,并配合实行对初轨坯或连铸坯热堆垛缓冷却除氢以满足合理安排耐磨重轨新品种生产工艺需要的可行性问题。对我国攀钢和包钢两个高原钢厂生产重轨由于钢水中的含氢量很低、在热锯轨头中白点发生率极低,甚至不出白点的现象进行了分析,讨论。
