The control technology of inclusions in steel for tyre cord and saw wire in "BOF-LF refining-Bloom CC" process is summarily reviewed. The plasticization of inclusions in steel is realized by using the measures including using Si- Mn deoxidation

strictly controlling Als content in liquid and refining with low basicity (CaO/SiO

≤1.0) slag. Production practice shows that the plasticization of inclusions in steel is not fully equal to controlling inclusion in low-melting point region

at some steelworks the MnO-SiO

series inclusions in coil for saw wire are not controlled in low-melting point region but these inclusions are nicely deformable during rolling process. The exogenous inclusions caused by refractories should be avoided in production process and the frequency of wire breakage could be remarkabl
