top-blast refining

A Cupola Suited to Smelt High Temperature and Top Quality Molten Iron By the technical principal analysis of smelt refining casting, extrusion and finish rolling.

熔炼高温优质铁水的卡腰冲天炉通过对熔炼、铸造、挤压及精整各工序的工艺原理分析。

The results showed that the tested top slag+ wire feeding slag had high sulphur capacity ( logC S being-1.6~ 0.5) which were available for desulphurization of ultra-low sulphur steel during refining;

结果表明，该顶渣+喂线渣具有高的硫容量（logCS为-1.6～0.5），适用于超低硫钢的精炼脱硫；

Top-slag refining process in CAS-OB unit under inert gas protection is introduced.
