由于提高高炉煤气的压力,降低了装料装置的寿命,特别是在炉顶压力高于0.8计示大气压的工作情况下更是如此。1959年10月,在契廖宾斯克工厂的一座高炉上安装了装料装置(图1),其接触表面的倾角增大到60°,以使接触表面更紧密的接合。大料斗和大料钟的下边缘设计成这样:大料斗偶然有掩盖不严时,煤气流方向切于表面,并消除煤气流的激烈变换方向和产生旋涡。大料斗和大料钟的壁厚差不超过15毫米,以
As a result of increasing the pressure of the blast furnace gas, the life of the charging device is reduced, especially if the top pressure is above 0.8 atm. In October 1959, a charging device (Fig. 1) was installed on a blast furnace at the Chiaiaobinsk plant, with the contact surface increasing in inclination by 60 ° to bring the contact surfaces into closer engagement. Large hopper and the lower edge of the large bell designed to do so: large hopper occasionally masked lax, the gas flow cut in the direction of the surface, and to eliminate the fierce gas flow direction and the transformation of whirlpool. Big hopper and the bell of the wall thickness difference of not more than 15 mm
