In leading countries around the world, research is being conducted on the development of dry slag granulation plants (DSGPs) for blast-furnace slag; these plants support production of dry granulated slag and recovery of physical heat from slag. The design and construction of laboratory or pilot dry granulation plants requires engineering techniques that can be used to design the major components of the plant. The most important component of a dry slag granulation plant is a horizontally rotating device (disk) for spraying slag (a disk), with the molten slag being fed onto this disk. As the slag interacts with the disk, the slag is atomized into drops with a diameter of 1–2 mm that move radially at a speed of 5–15 m/sex through the interior of the granulation chamber, where they undergo radiant and convective heat exchange, and solidify before they come into contact with the cylindrical wall of the chamber. Knowing the maximum diameter d of the molten slag droplets and the speed w at which they move through the granulation chamber, it is possible to estimate the geometric and operating parameters of the spraying device (disk): The disk radius r₀, the rotation frequency f of the disk, the maximum slag flow rate G_max at which the slag becomes atomized, as well as the mechanical power N required for rotation of the disk.

In this paper, we obtain fairly simple expressions that enable us to determine the values of r₀, f, G_max, and N as a function of the parameters d and w, and present the results from an analysis of these functions. This analysis also takes into account the thermophysical properties of blast furnace slag: density, coefficient of viscosity, and the coefficient of surface tension. For example, slag droplets with diameter 2 mm and speed 5 m/sec cool in the granulation chamber from 1500 to 1200°C (guaranteed solidification temperature) in about 0.7 sec, in which case the radius of the chamber should be at least 3.5 m. The rotating disk should be approximately 0.047 m in diameter, with a rotation frequency of 16.8 Hz. The maximum volume flow rate of sprayed slag is 0.0035 m³/sec = 12.6 m³/h. The specific consumption of mechanical energy for the disk drive will be ≈ 0.0105 kW·h per metric ton of molten slag. As the droplet velocity w increases, the size of the granulation chamber and the values of r₀, G_max, N will increase significantly, and the rotation frequency of the disk will decrease. As the droplet diameter d decreases, the size of the granulation chamber and the values of r₀ and G_max will significantly decrease, the frequency f will increase, and there will be a slight increase in the power N.

世界主要国家正在研究开发高炉矿渣干法造粒设备（DSGPs）；这些工厂支持生产干粒状炉渣和从炉渣中回收物理热量。实验室或中试干法制粒设备的设计和建造需要可用于设计设备主要部件的工程技术。干渣造粒设备最重要的组成部分是水平旋转装置（圆盘），用于喷渣（圆盘），熔渣被送入​​圆盘上。当炉渣与圆盘相互作用时，炉渣被雾化成直径为 1-2 mm 的液滴，这些液滴以 5-15 m/s 的速度径向移动通过造粒室内部，在那里它们接受辐射热和对流热交换，并在它们与腔室的圆柱形壁接触之前固化。知道最大直径d熔渣的液滴和速度的瓦特其中在它们穿过造粒室移动，也能够估计喷射装置的几何和操作参数（磁盘）：磁盘半径- [R ₀，旋转频率˚F盘的，炉渣雾化的最大炉渣流量G _max，以及圆盘旋转所需的机械功率N。

在本文中，我们获得了相当简单的表达式，使我们能够确定r ₀、f、G _max和N 的值作为参数 d 和 w 的函数，并提供对这些函数的分析结果。该分析还考虑了高炉炉渣的热物理特性：密度、粘度系数和表面张力系数。例如，直径为 2 mm、速度为 5 m/sec 的渣滴在造粒室中从 1500°C（保证凝固温度）在 0.7 秒内冷却，在这种情况下，室的半径应至少为 3.5 m . 旋转盘的直径应约为 0.047 m，旋转频率为 16.8 Hz。喷渣最大体积流量为0.0035 m ³ /sec = 12.6 m ³/H。磁盘驱动器的机械能单位消耗将≈ 0.0105 kW·h 每公吨熔渣。随着液滴速度w的增加，造粒室的尺寸和r ₀，G _max，N的值将显着增加，并且圆盘的旋转频率将降低。随着液滴直径d的减小，造粒室的尺寸和r ₀和G _{max 的值}会显着减小，频率f会增加，并且功率N会略有增加。
