SEM analysis shows that after inoculater Si-Fe is added, the distribution of Si is heterogeneous which makes low temperature graphitization of the malleable cast iron easy.

扫描电镜分析表明，加Si-Fe孕育后，由于Si分布的不均匀使得可锻铸铁的低温石墨化过程易于实现。

Improvements According to the causes of valve casting defect, we are mainly taken from the following improvements:(1) appropriately increasing the iron liquid carbon equivalent expansion of the use of graphite materials to enhance the ability of self-feeding.

改进措施根据阀门铸件缺陷的成因，我们主要从以下几个方面采取了改进措施：(1)适当提高铁液碳当量，利用石墨化膨胀增强材质的自补缩能力。

Due to the suppression of reverse water gas shift reaction by adding steam in feed gas, more CO〓 participated in and promoted CO〓 reforming of CH〓 reaction, higher catalytic activity and less carbon deposition were obtained. On the surface of used catalyst there were two kinds of carbon species deposited on catalyst, one was decomposed CH〓 fragment, and the another was graphiticlike carbon.

在反应后催化剂表面有两类碳物种，一类在250～350℃出现的少量α-碳，应主要是活性高的CH〓解离碎片，一类是在700℃附近出现的β-碳，应是导致催化剂失活的类石墨化碳。

Gray castiron works may be repaired by arc welding with electrodes of 08 or ordinary iron wire covered with special coating which contains ferro-aluminium and other graphilizers. During welding process, it is found that these electrodes produce a weld of gray cast iron structure.
