Embodiment Construction

[0023] Such as figure 1 As shown, an electric vibration cutting control method provided by the present invention includes:

[0024] Step 1: Pre-set E1 value, K value, control limit D and specification limit 2D. Among them, the blanking advance E1 is obtained through experimental statistics. The initial value of E1 is determined, which is related to the angle adjustment of the electric vibration equipment and the particle fluidity of the material. For example, the set value of the blanking is in Kg. The general setting is The material drop value E is a value of 2-6Kg. After the blanking test, observe the deviation value Q. The E value where Q is close to 0 is a relatively suitable drop value. After the control method is put into use, the system will automatically adjust the E value. Make Q stable within the control limit. K is the correction coefficient, and the value range of K is controlled within 0.5-1.

[0025] Step 2: When the difference between the displayed value PI of the ...

Abstract

The invention discloses an electric vibration discharging control method and a corresponding system. The method comprises the following steps of: correcting the discharging fall value E2 according to an equation of E2=E1+ / -K when absolute value of offset value Q1 between the final discharging quantity Pa and the defined discharging quantity Ps at first time, and absolute value of offset value Q2 between the both at second time are greater than predefined control limit D; the E1 is the discharging predefined quantity; and the K is the repair coefficient and is controlled to be 0.5-1. The system comprises a calculation module, a judgment module, a correction module, a control module, an alarm module and a setting module. The method and the system can greatly improve discharging control accuracy in the steel making process so as to effectively improve regulation and control capability on liquid steel components.

Description

Technical field [0001] The invention belongs to the technical field of metallurgical electric vibration cutting control technology, in particular to an electric vibration cutting control method and system. Background technique [0002] The electric vibration feeding control device for the ferroalloy and bulk material system of the metallurgical industry steelmaking plant is an important equipment for controlling the composition of molten steel. It is composed of a hopper, an electric vibration device, a weighing device, and an electric vibration electric control system. Due to the obvious hysteresis of the electric vibrating feeder for blanking, if the starting and stopping of the blanking equipment is controlled according to the actual reading of the weighing equipment, it will inevitably lead to excessive blanking. The general solution is to indirectly control the flow rate of the alloy from large to small. When the feeder stops, the smaller the flow rate of the alloy, the easi...
