Problems solved by technology

The problem in the background technology is that the roll gap must be adjusted when each segment breaks down or is overhauled in the maintenance workshop. Every time the roll gap is adjusted, manual measurement and adjustment are repeated. It usually takes 4 hours to adjust the roll gap of a segment ; High labor intensity and low work efficiency

Embodiment

[0059] Adjust section B of the fan-shaped section, and check the maintenance regulations to know that the target roll gap of this fan-shaped section is: the entrance roll gap is 238.4mm, the exit roll gap is 237.8mm, and the current actual measurement: the entrance roll gap is 239.58mm, the exit roll gap is 238.12mm,

[0060] Then, calculate the actual and target roll gap difference

[0061] Δimport=-1.18, Δexport=-0.32,

[0062] According to mathematical simulation 3 / 4X-1 / 3Y=-1.18

[0063] 3 / 4Y-1 / 3X=-0.32

[0064] Solved; X=-2.2, Y=-1.4

[0065] Then the gasket needs to be pulled out by 2.2mm at the inlet clamping hydraulic cylinder, and the gasket needs to be removed by 1.4mm at the outlet clamping hydraulic cylinder. Using EXCEL, based on the mathematical simulation of the roll gap of the continuous casting segment, the attached Figure 8 Quick calculation form, when adjusting the roll gap value of the fan section, only need to input the target roll gap value and the...

Abstract

The invention relates to a method for regulating fan-shaped section roller seams of a continuous casing machine by using a mathematical model. The method is used for regulating the fan-shaped section roller seams of a Danieli plate blank continuous casting machine of metallurgical enterprises, and belongs to the technical field of continuous casting equipment. The method has the technical scheme that the inlet and outlet roller seams of fan-shaped sections are respectively and practically measured, and the deviation value with the standard roller seam is worked out; a mathematical model among the fan-shaped section inlet roller seam, the outlet roller seam deviation value and the roller seam value to be regulated is built, and the number of gaskets at an inlet clamping hydraulic cylinder part and an outlet clamping hydraulic cylinder part is respectively regulated. The method has the advantages that only the fan-shaped section inlet roller seam and the outlet roller seam need to be measured before the regulation, the difference value with the standard roller seam is worked out and is directly introduced into a mathematic model equation set, and the increase and decrease quantity of the inlet and outlet roller seam gaskets can be obtained. The regulation of the fan-shaped roller seams can be realized in one step, one hour is needed at most, the work efficiency is improved, a great amount of labor is saved, and wide popularization and application prospects are realized.

Description

technical field [0001] The invention relates to a method for adjusting the roll gap of a sector section of a continuous casting machine by using a mathematical model, which is used for adjusting the roll gap of a sector section of a Danieli slab continuous casting machine in a metallurgical enterprise, and belongs to the technical field of continuous casting equipment. Background technique [0002] Danieli DANIELI slab continuous casting machine is widely used in most metallurgical enterprises in my country because of its advantages of being able to cast various steel types including ultra-low carbon steel, low, medium and high carbon steel, peritectic steel and microalloy steel. For example: Shougang Jingtang, Valin Lianyuan Steel, Baotou Steel Plant and other companies are using it. The Danieli continuous casting machine has five types of segments A, B, C, D, and E. Among them, the two types of segments A and B are arc segments, and the inner and outer arc roller surfaces a...
