摘要： Described herein is a stabilized lubricant composition for use in steel casting, in particular in continuous casting processes. In particular, the lubricant composition for processes for producing steel by continuous casting includes a dispersion of a lubricant powder, for an ingot mold, in continuous casting, in an oily liquid means, and a stabilization additive, characterized in that it has the following shear thinning index values: RVT
0.1/1
1/10
10/100
100/1000 STI
3.0-7.5
2.0-6.5
1.0-3.0
0.5-2.0 wherein RVT is the ratio between two different shear speeds and STI is the shear thinning index corresponding to the RVT values.
