CC - Opis:
- To figure out the reason causing ladle nozzle clogging during CC (continuous casting) of a non-oriented electrical steel with high silicon (or HNO for short) and get a method to address it, this paper studied the theoretical calculation of flow rates during CC, the inclusions around the slide gate where ladle nozzle clogging happened, and Ca-treatment at the end of RH for decreasing ladle clogging of the electrical steel both theoretically and practically. The results showed that: The bigger diameter of a nozzle or less nozzle clogging can guarantee an enough flow rate for reaching the target casting speed. Ladle nozzle clogging can be predicted by comparing the percentage of slide gate opening. Al2 O3 and its composite inclusions were the main reason that caused the ladle nozzle clogging of the electrical steel. Higher [Al] or TO will increase the amount of Pure Ca wires for Ca-treatment. The results of the verification tests fit the thermodynamic calculation, and Ca-treatment using pure Ca wires could prevent ladle nozzles from clogging without affecting the magnetic properties of the electrical steel.
