; Figure 5 between the end sets with bad graphite Fig. 5Amistakeconjugationbetweengraphitesheath end sets in the processing of graphite, the graphite sets strict accordance with the standards process to ensure that the two sets of graphite between the right combination of face, shown in Figure 6. 3.4 Other aspects of casting production. Iron out the initial phase profile is applied by means of a dummy bar head to achieve a special dummy. Began production in continuous casting. Dummy bar equipped with the special dummy head into the hole in the mold, then the holding furnace hot metal into the mold, solidification of the molten iron has a good profile before the peak and the dummy header to implement combination of graphite and then throwing power sets of the normal combination of l-_. . . . . . . . . . . . . 1'''. .

At the beginning of production. The shape of the engine head is not good and poor surface quality can also cause injury accident. Dummy head and the surface of poor quality, or even above the burr, insert mold, the kit will scratch the surface of graphite mold in continuous casting, comprising the graphite surface has been scratched the surface profile will result in injury accident . 4 Conclusion vertical to the above, the process of iron casting surface strain profile accidents caused by a variety of reasons, and damage the surface quality of graphite comprising most of the beginning of the continuous casting production due to poor process control, Once the graphite surface, comprising a greater degree of scratch,[link widoczny dla zalogowanych], the entire continuous casting process produced by the strain will have the phenomenon of surface profiles. Of course,[link widoczny dla zalogowanych], the problem can not be torn casting surface profile of a process through the above method can be completely solved, often by the combined effect of many factors. Should be combined with actual production from different areas, namely, strict control from above, through the scene again, trial production, the surface strain profile can be resolved the problem.

(2) heat treatment can significantly improve the high-boron alloy hardness and wear resistance. The impact toughness of high boron alloy with very high chromium cast iron under the premise of high boron alloy hardness and wear resistance have been greatly improved. Therefore, as a new type of wear-resistant material. References:, l】【Li Wei. Progress steel wear-resistant materials】【J. Foundry, 2006,55 (11): llO5.1109. 【2】 FU Han-guang.
