Because of containing more sulfur and phosphorus in the steel, and more carbon, high hardness in material of surfacing welding, the pinch roller often turns up hot crack. 夹送辊堆焊时,由于母材的硫、磷含量较高及堆焊材料含碳量高、硬度大,常常产生热裂纹。
By means of analysis on fissure feature of solvent regeneration tower in sulfur removal and sulfur manufacturing unit of refinery, recognized that: this type of fissure was the results of hydrogen induced crack ( HIC) under wet hydrogen sulfide environment combined with sulfur corrosion. 通过对炼油厂脱硫制硫装置溶剂再生塔裂纹特征的分析认为,此类裂纹是湿硫化氢环境下的氢致开裂(HIC)和硫腐蚀共同作用的结果。
According to the character of continuous casting slab and sulfur print examination on the produced slab, this paper analyse the formation of the triangle zone crack. 根据板坯连铸机的特点,结合低倍、硫印检验结果,对于板坯三角区裂纹的成因进行了分析。
Based on the quantitative data of internal crack by image recognition system of sulfur print and in the light of internal crack mechanism, a statistical analysis for internal crack is made. 在利用硫印图像自动判级系统得到的内裂定量化数据的基础上,结合连铸板坯内裂产生机理,对内裂进行了统计分析。
Using temperature, mold level, mold powder, steel grades, and carbon content, sulfur content and phosphorus content of liquid steel, it predicts the surface crack of the casting slab. 运用热电偶温度数据,结合结晶器液面、保护渣、钢号、钢液C、S、P含量等数据用于板坯表面裂纹预报。
