Abstract

The invention discloses a rotating speed control system for an INBA rotary drum. The rotating speed control system comprises a motor which is connected with a transmission shaft and a bearing through a reducer. A rotary drum is installed on the transmission shaft and the bearing, and is located in a cooling pool. A torque meter is installed on the motor and is mainly used for measuring the torque of the motor in real time. The cooling pool is filled with cooling water and is provided with water lines including a highest water line, a baseline water line and a lowest water line. A plurality of scale water lines are arranged between the highest water line and the lowest water line, and are evenly distributed on both sides of the reference water line. A water level monitoring system is also arranged in the cooling pool. The invention also discloses a rotating speed control method for the INBA drum. The system and method can control the cooling time of water granulated slag, improve product quality, automatically stops the motor in case of an over-high or over-low water level, avoids damage of high-temperature water granulated slag to equipment, and reduce a failure rate.

Description

technical field [0001] The invention relates to a method for regulating the rotational speed of an INBA drum, in particular to a method for controlling the speed of a blast furnace INBA system drum, and belongs to the technical field of blast furnace intelligent control. Background technique [0002] The blast furnace INBA system mainly uses high-pressure water to water-quench the slag to form water slag. Among them, the INBA drum is the core equipment of the INBA system, which mainly adjusts the slag cooling time through the rotating speed, which has a decisive influence on the slag treatment quality. At present, because the blast furnace slag discharge flow is unstable and cannot be effectively detected, constant speed is used to control the drum speed at home and abroad, but there are problems such as uneven slag particle size and frequent failures of the transmission system. For this reason, developing a reasonable control method for the drum speed is of great benefit t...
