Abstract：As a stabilizing element, Ti is added into stainless steel 321, which leading to nozzle clogging, mold"floater" and poor surface quality of the slab during continuous casting process. The situation is more serious when the low cost nickel-bearing pig iron with high sulfur and high phosphorus contents is employed as raw material. To solve the problems, laboratory analysis for nozzle clogging and mold "floater" was made by Baosteel stainless steel company. The key factors of Ti, N and O during production process was set, and the problems during steel casting process was basically solved, thus the product quality was guaranteed.
