Method for automatically detecting and controlling segment roll gap by adopting balancing oil cylinder

Abstract

The invention relates to manufacture of large panels, strips, sectional bars and the like in ferrous metallurgy industry, in particular to a method for automatically detecting and controlling a segment roll gap by adopting a balancing oil cylinder, which is characterized by at least comprising a lower frame with a guide roll, an upper frame with a guide roll, a hold down roll device for driving adummy bar and a casting blank, balancing oil cylinders used for roll gap detection and control, and a clamp oil cylinder for connecting the upper frame and the lower frame and keeping the roll gap, wherein the hold down roll device is fixed in the upper central position of the upper frame, and the balancing oil cylinders are evenly distributed between the upper frame and the lower frame, so that a plate blank continuous casting machine dynamically and lightly presses the solidified end of the casting blank in the production process of pouring steel, the quality defects of center segregation, rarefaction and the like of the casting blank can be effectively avoided, and the steel quality and the metal yield are improved.

Description

technical field [0001] The invention relates to the production of large-scale plates, strips and profiles in the iron and steel metallurgy industry, and in particular to a method for automatically detecting and controlling the roll gap of a sector section by using a balance oil cylinder. Background technique [0002] Continuous steel casting technology has been widely used in modern iron and steel enterprises due to its advantages of energy saving, low consumption and high quality. In addition to a very small amount of cast steel production, rolling blanks for various plates and strips, rods and wires, profiles, seamless steel pipes, etc. are provided by continuous casting production methods. The blanks provided for plate and strip rolling are continuous casting slabs, and the core of its production technology is the slab continuous casting machine. [0003] With the improvement of steel quality requirements in the machinery manufacturing industry, automobile industry, ship...

AI Technical Summary

Problems solved by technology

Especially during production, the thermal deformation caused by high temperature cannot be detected, so when the dynamic light reduction operation is performed, the error of fine-tuning the roll gap is required to be larger, and it is not stable enough, and the production process is difficult to achieve accurately. The metallurgical effect of pressing is also unstable
