内容简介

The research progress and industrial application of chrome-free refractories for RH degasser were introduced in the paper. It is proved that unburned magnesia-spinel refractories used for RH throat and snorkel in Baosteel have longer service life compared with traditional direct bonded fused magnesia-chrome materials. The new developed chrome-free unburned magnesia-spinel composite can fully meet the present demand for RH operation and can be applied extensively for RH processing. At present, instead of chrome-containing materials, chrome-free refractories have been applied widely for RH in Baosteel. Super low carbon MgO-C material with high mechanical properties at mild and high temperatures can be an alternative chrome-free material for RH.
