| Abstract: | The type,cause and engendering mechanism of 20 steel tube stock's surface crack in Xinyu Iron & Steel Co.,Ltd are detailed analyzed.Improving measures aiming at the technical problems during former steel tube producing are put forward and industrial producing experiment in accordance with the improved technology has been carried out.The experiment result and one year's practice prove that the surface's quality of the 20 steel tube has been apparently improved.The surface crack has been made obviously less and the scrap rate of the air chipper is remarkably reduced. |
