In present paper,the control technology of aluminum content and inclusion composition was analyzed for high-silicon and aluminum-controlled steel by technological test. The results showed that content of Al in steel can be controlled within 0.0040% by using low basicity slag with alkalinity below 1.5,while the Al content is higher than 0.006% by using high basicity slag with basicity 2.5 - 3.5. The decrease of Al

content, and the plastic deformation ability of the inclusion material is insufficient. High clean steel with oxygen content less than 0.001 2% and fine inclusions can be obtained after RH control processing, although deoxygenation effect of the steel with low basicity slag is poor in the refining process.
