Continuous casting machine sector section centering measurement method

Abstract

The invention discloses a method for central position control of fan-shaped sections in a continuous caster. The method comprises the following steps of: suspending a work piece to be test on a shaft supporter and a plane supporter on a test platform, installing four equal-altitude upright columns in the periphery of the test work piece, measuring the altitudes of the equal-altitude upright columns and reference plane of the test work piece by using a laser measurement device, installing two equal-altitude cross beams on the equal-altitude upright columns, measuring the altitudes of the equal-altitude cross beams by using the laser measurement device, placing a straight ruler on the equal-altitude cross beams, moving the straight ruler to each roll surface, and measuring the distance between each roll surface and the straight ruler by using an inside micrometer. The invention has the advantages of easy operation, high measurement accuracy, low cost and short measurement time.

Description

technical field [0001] The invention relates to a method for centering and measuring a segment of a slab continuous casting machine. Background technique [0002] The development trend of the modern iron and steel industry is to consider steelmaking-continuous casting-steel rolling as a whole, and complete the production process from molten steel to plate at one time. The production rhythm is no longer adjusted through inventory between processes. That is, qualified molten steel produced by steelmaking is supplied to the ladle turret in time according to the production rhythm of continuous casting. Reduce consumption and increase metal yield. At the same time, it reduces the cost of products and capital, improves the competitiveness of products in the market, and obtains the greatest economic benefits for enterprises. [0003] The segment used in the design of the whole slab continuous casting machine is to support the insertion of the dummy bar, cooling, straightening th...

Problems solved by technology

[0007] The disadvantage of using this method to detect the centering of the sector is: because the centering template needs to be processed by a CNC boring and milling machine, the production cost is high and the cycle is long

Secondly, the geometric size of the centering sample is large and the rigidity is poor. During transportation and use, the detection sample is easily deformed, which reduces the detection accuracy.

Furthermore, for products of different specifications, it is necessary to make multiple pieces and samples of various specifications, which cannot be reused, making the production cost very high
