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,<a href="http://www.airjordansshoescheapnike.com" target="_blank">air jordan shoes cheap</a>, the entire continuous casting process produced by the strain will have the phenomenon of surface profiles. Of course,<a href="http://www.stivaliuggitalia.org" target="_blank">ugg italia</a>, 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.
