| 摘 要： | 采用奥亚膨胀仪测定2种不同配比煤的b值，利用数学方法推算出最佳配比，并对最佳配比进行实验室炼焦验证。结果表明，利用奥亚膨胀仪结合数学方法推算出的2种煤最佳配合比例基本正确，但对某些惰性物较少且挥发分较高的中低变质煤种配合时存在反常现象。此方法也可适用于3种以上煤推算最佳配合比例，但误差可能会增大。 |
| 关 键 词： | 配煤炼焦 b值测定 最佳配比 |

| Abstract: | b value of coals with two different blending ratio was measured by Audibert-Arnu dilatometer, the optimal blending ratio was calculated by mathematical method, and the optimal blending ratio was proved by the coking test in laboratory. The results showed that the optimal blending ratio of two kinds of coals measured with Audibert-Arnu dilatometer in combination with mathematical method was basically correct. But for some low and middle rank coals with less inert matters and higher volatile matter, when blending it existed abnormal law and phenomenon. This method could also be applicable to calculate the optimal blending proportion of three or more kinds of coals, but the tolerance might be increased. |
| Keywords: | Cokemaking with coal blend b value determination Optimal blending ratio |
