转炉倾动力矩包括空炉力矩、液体金属倾动力矩和耳轴摩擦力矩。在转炉倾动过程中,耳轴摩擦力矩在出钢之前几乎没有变化;空炉力矩虽有变化,但由于炉体的重心位置不变,因而较易确定,其数值均可按计算公式求得。然而,液体金属的重心位置 Converter tilting torque includes empty furnace torque, liquid metal tilting torque and trunnion friction torque. During the tilting of the converter, the friction torque of the trunnion hardly changes before the tapping. Although the empty furnace torque changes, the value of the furnace body can be determined by the calculation formula because the center of gravity of the furnace body is unchanged. However, the liquid metal’s center of gravity position
