Slag formation in the tundish of a continuous-casting machine is investigated during the casting of 360-t low-carbon and low-alloy steel melts. In casting 5–10 steel melts, the slag mass increases significantly, and its composition changes. That is largely associated with the supply of nonmetallic inclusions to the slag from the steel. In casting low-carbon steel, the mass of such inclusions is around...
Attention focuses on how certain activators affect the parkerizing process and the properties of the phosphate films obtained. Comparative corrosion-endurance tests of the films obtained are conducted. The effectiveness of such activators in production conditions is established.
