前苏联冶金学家巴甫洛夫所定义的铁的直接还原度的计算方法在炼铁计算中应用十分广泛,一些重要的炼铁计算,如热平衡、物料平衡、理论焦比等的计算都离不开直接还原度计算。直接还原度的计算方法有碳氮平衡法、碳平衡法和热平衡法三种,其中碳平衡法因使用煤气相对体积进行计算,所以一直被认为是误差相对较小的一种方法。作者认为,碳平衡法计算公式的原则是正确的,但因计算公式对高炉内氢行为的考虑欠周全,使
The method of calculating the direct reduction degree of iron defined by the former Soviet metallurgist Pavlov is widely used in the calculation of iron smelting. Some important iron smelting calculations such as heat balance, material balance, and theoretical coke ratio are all calculated Do not open the direct reduction calculation. There are three methods for calculating the direct reduction degree: the carbon-nitrogen balance method, the carbon balance method and the heat balance method. Among them, the carbon balance method is calculated by using the relative volume of the gas and has been considered as a method with a relatively small error. The author believes that the principle of carbon balance formula is correct, but because of the calculation formula for hydrogen in the blast less thoughtful, so that
