研制了一套喷嘴模底吹氩装置,并成功地用于工业实验中。在实验室冷态模拟试验的基础上,制定了模底吹氩工艺,进行了39炉工业试验。试验证明:采用模底吹氩,可以减少钢中有害气体;改善钢锭铸态组织结构。从而,可提高钢的机械性能,减少钢锭废品率。 Developed a nozzle mold argon blowing device, and successfully used in industrial experiments. Based on the laboratory cold simulation test, a mold blowing argon process was developed and 39 furnace industrial tests were carried out. Experiments show that: the use of argon at the bottom of the mold, you can reduce the harmful gases in steel; improve the ingot as-cast structure. Thus, the mechanical properties of the steel can be improved, reducing the rate of ingot rejection.
