Automatic control device and method of rotary chute pair transmission tilt angle of blast furnace bell-less top

Abstract

The invention provides automatic control device and method of a rotary chute pair transmission tilt angle of a blast furnace bell-less top for automatically controlling the tilt angle of a chute. The automatic control device comprises information collection equipment, a PLC control system and transmission equipment, wherein the information collection equipment is used for collecting the tilting angle position information of the chute and the position information of the chute and transmitting the information to the PLC control system; the PLC control system is used for analyzing the information collected by the information collection equipment, generating a control signal and transmitting the control signal to the transmission equipment; and the transmission equipment is used for controlling the tilting angle of the chute according to the control signal of the PLC control system. The device and the method eliminate the influence brought by deviations caused by the angle alignment control of the stroke of a chute pair transmission tilt angle drive linear oil cylinder on the material distribution of the blast furnace, sufficiently give play to the ideal material distribution superiority of the bell-less material distributor and guarantee the stability of a smelting process. In addition, the invention can prevent the frequent switchover of an electromagnetic directional valve of the chute pair transmission tilt angle drive linear oil cylinder and keep the stable output characteristics of a hydraulic system.

Description

technical field [0001] The invention relates to an automatic control device and a control method for bellless top equipment of a blast furnace, in particular to an automatic control device and method for a hydraulic system of a rotary chute auxiliary transmission inclination angle (α angle) of a bellless top equipment of a blast furnace. Background technique [0002] The focus of the present invention is the automatic control of the linear oil cylinder driven by the inclination angle (α angle) of the chute auxiliary transmission of the blast furnace bellless top chute, referred to as the automatic control of the α angle position for short. The automatic control of the α angle position and the automatic control of the chute main drive (β angle) position are directly applied to the technical field of blast furnace production and smelting, and are mainly used to solve the problems of stable operation and uniform distribution of charge in blast furnace production.
