In this paper an attempt has been made,by a model test, to find out the behavior of flow of primary slags in blast furnace. It has been verified that the slags within softening-melting zone flow downward along the declination of this zone and gether together at its lowest part where the slags fall down. Therefore, slags near to the wall flow downward rather more than in the middle part of the furnace when the softening-melting zone is of a shape of inverse V. Conversly, slags in the middle part flow downward...

In this paper an attempt has been made,by a model test, to find out the behavior of flow of primary slags in blast furnace. It has been verified that the slags within softening-melting zone flow downward along the declination of this zone and gether together at its lowest part where the slags fall down. Therefore, slags near to the wall flow downward rather more than in the middle part of the furnace when the softening-melting zone is of a shape of inverse V. Conversly, slags in the middle part flow downward rather more when the zone V-shaped. As to the W-shaped zone, an intermediate state would be appeared. In tuyere region, the flow path of slags change again due to the effect of gas flow in raceway, such that a dry region below raceway occurs. Based on the analysis above, a model to show the behavior of slag flow in blast furnace has been developed qualitatively.

本文试图通过模型试验对高炉内初渣流动规律性问题进行研究。试验证明,在高炉中的成渣带(软融层)内的渣沿成渣带向下流动,并在其最低处汇聚后流下。因而,成渣带呈倒V形时,边缘部份流下的多;呈V形时中心部份流下的多;W形则介于二者之间。在风口区,下降的炉渣,由于受到回旋区气流的影响,流动轨迹又发生变化,在回族区下方出现干区。根据以上分析,定性地做出了高炉内炉渣流动模型。

Making the model experiment as similar to the actual operation of a blast furnace as possible, this paper presents a quantitative investigation on the behavior of the flow of primary slag in blast furnaces. It is found that a strongly horizontal gas flow occurs in blast furnaces due to the softening melting-zones and the coke layers.Primary slag is therefore forced to fall down out of the vertical and then outflow together to the lower ends of the softening melting-zones.

Making the model experiment as similar to the actual operation of a blast furnace as possible, this paper presents a quantitative investigation on the behavior of the flow of primary slag in blast furnaces. It is found that a strongly horizontal gas flow occurs in blast furnaces due to the softening melting-zones and the coke layers.Primary slag is therefore forced to fall down out of the vertical and then outflow together to the lower ends of the softening melting-zones. The semiemperical relationship of the angle 9 out of the vertical may be expressed aswhere (dP/dL)G/γl is the dimensionless pressure gradient, μl and γl the viscousityand the specific gravity of melts respectively, L and G the gravitational flow of melts in liquid and gaseous states, fs the surface area of piled melts and ε the porousity. These formulas imply that the angle θ relates to the air blast or its velocity, the specific gravity and viscousity of melts and other properties of burden. A metallurgic analysis has been made for the relation between the angle θ of the flow of primary slag and the operation of blast furnaces.

本文通过模型试验,在尽可能考虑与高炉相似条件下,研究了高炉内初渣流动规律。结果表明:由于高炉内存在软熔带和焦炭夹层,因而在在较强的水平煤气流。初渣带在水平煤气流的作用下产生偏离垂直方向的流动,使初渣有某种程度集中流下现象。初渣流动的偏角 θ 是无因次压力梯度(dP/dL)_g/γl、准数(Fr_l)/(Re_l)及无因次流量 L/G的函数。即偏角θ是风量,熔体比重、粘度及流量和炉料性质的函数。利用此式,分析了初渣流动的偏角θ与高炉冶炼的关系。

At the same time, the hydraulic experiment regionally simi1ar to a B. F.has been made. The calculated results are on the whole consistent with experimental ones.

According to the continuum approach in a porous medium and the modified Ergun equation, amathematical model is developed, which describes the counter-current flows of gas and liquid streamthrough a packed bed. At the same time, the hydraulic experiment regionally simi1ar to a B. F.has been made. The calculated results are on the whole consistent with experimental ones. The results showthat, under the condition that softening zone is inverse-V shape, the inclined flowing of the liquidslag in dropping zone will take place because of the influence of gas flow. The distribution of pri-mary slag on the cross-section in dropping zone is binomial (abnormal). Under normal conditions,the inclined flowing of primary slag is mainly affected by the type of softening zone including itsshape and its inner construction. This phenomenon is also an important factor that deteriorates thepermability of dropping zone, especially the coke layers of softening zone. On this basis, thispaper presents the reasonable measures to improve the operation of B. F.

根据多孔介质的连续介质方法,结合修正的Ergun方程,建立了高炉初渣流动的数学模型;同时,在考虑与高炉区域相似的条件下,对此进行了模型实验研究。结果表明:对于倒V型软熔带,因受气流运动特性的影响,滴落带液体将发生偏流;初渣在滴落带横截面上呈二次项分布(偏态的);初渣偏流主要受软熔带类型(包括形状和内部结构)及风量的影响,同时,又是恶化滴落带,尤其是恶化焦窗透气性的重要因素。据此,本文提出了改进高炉操作的合理措施。
