Problems solved by technology

However, affected by factors such as equipment capacity, implementation deviation, metal solidification properties (expansion and contraction in non-preset forms), the slab does not solidify completely according to the preset or recognized laws during the continuous casting production process. Therefore, according to The reduction control preset by the system may not be able to achieve the predetermined reduction target. If the reduction is too large or too small, it will have a great impact on the solidification quality of the slab

Abstract

The invention relates to a continuous casting blank thickness online measuring and pressing amount adjusting system. The continuous casting blank thickness online measuring and pressing amount adjusting system is characterized by comprising a continuous casting blank online distance measuring device, a casting blank thickness feedback system and a continuous casting machine pressing adjusting system; and the continuous casting blank online distance measuring device which is fixed above a casting drawing section of the continuous casting machine measures a distance from a source point to each appointed point of a casting blank according to a certain frequency, a casting blank thickness feedback system is applied to calculate the thickness of the casting blank according to the measured distance, then a result is fed back to a secondary system of the continuous casting system, and an existing continuous casting machine pressing adjusting system is applied to adjusting the pressing amount.By adopting the continuous casting blank thickness online measuring and pressing amount adjusting system, the thickness of the casting blank in the online continuous casting process can be accuratelyand rapidly fed back in real time, and deviation of the pressing amount of the casting blank in the continuous casting production process influenced by factors, such as the capabilities of continuouscasting equipment, implementation deviation in the pressing process and metal solidification property (non-preset form expansion and shrinkage), are avoided, so that the function of continuous casting pressing is exerted to the maximum, and the solidification quality of the casting blank is improved.

Description

technical field [0001] The invention relates to a system for on-line measurement of continuous casting slab thickness and adjustment of reduction amount. It belongs to continuous casting control equipment in the metallurgical industry. Background technique [0002] Continuous casting in the metal smelting industry is a process in which metal is poured through a continuous casting machine from a liquid to a solid state with preset dimensions. Slab reduction in the continuous casting process is one of the effective technologies to improve the internal defects of the slab. The existing reduction system is usually set and controlled according to the preset reduction program. However, affected by factors such as equipment capacity, implementation deviation, metal solidification properties (expansion and contraction in non-preset forms), the slab does not solidify completely according to the preset or recognized laws during the continuous casting production process. Therefore, ac...
