Heating furnace discharging roller way control system

Abstract

The invention discloses a heating furnace discharging roller way control system which comprises a heating furnace control system and a rolling line control system and further comprises a discharging roller way control system for controlling a heating furnace discharging roller way. The furnace discharging roller way control system is in communication connection with the heating furnace control system and the rolling line control system respectively. The speed of the heating furnace discharging roller way is matched with the speed of a heating furnace cantilever roller way and the speed in front of a first rolling mill, the heating furnace discharging roller way is driven by 16 motors, and the heating furnace discharging roller way is divided into five sections including the RT01 section, the RT02 section, the RT03 section, the RT04 section and the RT05 section. A first hot metal detector HMD01 is arranged between roller way bodies of the RT01 section and the RT02 section, and a second hot metal detector HMD02 is arranged between the RT04 section and the RT05 section. According to the heating furnace discharging roller way control system, fine control over the furnace discharging roller way is achieved, the yield is improved, and the friction problem caused by speed mismatching between the roller way and a steel billet is solved.

Description

technical field [0001] The invention relates to a control system for a furnace discharge roller table, in particular to a furnace discharge roller table control system for a heating furnace, and belongs to the technical field of furnace discharge roller table control systems. Background technique [0002] The original roller table control does not have a separate control system, but the roller table is simply divided into three sections. The speed of the first two sections is consistent with the cantilever roller of the heating furnace, and the speed of the last section of the roller table is the same as that of the No. 1 rolling mill after the steel billet bites into the No. 1 rolling mill. The speed of the rolling mill is matched; due to the small number of sections and the large number of roller table motors in each section, in the case of a large billet gap, most of the roller tables are in a no-load waiting state without a load and cannot be finely controlled. In additio...

Problems solved by technology

[0003] In order to solve the above problems, the present invention proposes a control system for the roller table of the heating furnace, which realizes the communication between the control system of the heating furnace and the control system of the heating furnace and the control system of the rolling line respectively. #Rolling mill speed, under the interlocking of the newly added two sets of hot metal detectors, realizes the fine control of the roller table of the furnace, improves the output, and reduces the friction problem between the roller table and the billet due to the speed mismatch
