The thee of Boron can improve the uniformity of microstructure and distribution of composition in alloy.
微量的硼改善合金钢的组织与成分均匀性；
With increasing the thickness, the temperature gradient in thickness direction is larger for the same cooling intensity, which would affect the uniformity of the microstructure in strip.
同时还表明随着带钢厚度增加，超快速冷却条件下厚度方向的温度梯度显著增大，对于带钢内部组织的均匀性将产生不利的影响。
The original brick consists of fused magnesia-chromite grains and raw chromite grains and its microstructure is non-uniformity.
原砖由电熔镁铬颗粒和铬矿颗粒组成，其显微结构是不均匀的。
