Problems solved by technology
The internal core of the more popular metal in situ analyzer is actually the direct reading spectrum. During the use, there is serious spectral drift, which requires frequent standardization, and there are too few standard samples that the metal in situ analyzer can refer to.

Embodiment Construction
[0009] The invention provides a casting slab component segregation drilling sampling method and a casting slab segregation detection method for precise and quantitative analysis of carbon and sulfur elements by using an infrared carbon-sulfur meter.
[0010] According to the invention, the slab component segregation drilling sampling detection method mainly includes the steps of sample collection, sample drilling position selection, infrared carbon sulfur meter to analyze the samples obtained from the drilling, statistical analysis results and other steps. In the present application, preferably, the sample has a rectangular shape.
[0011] Specifically, the slab composition segregation drilling sampling detection method according to the present invention mainly includes the following steps:
[0012] (1) Collection of analysis samples: collect the low-power acid leaching inspection samples of cast slabs during the production process as analysis samples, and carry out necessary ...

The invention discloses a casting blank ingredient segregation drilling sampling method. The sampling method comprises the following steps that two diagonal lines and a center line of a test sample in the width direction are marked; the test sample is divided into (n-1) equal parts along two edges of the test sample in the length direction and the center line in the width direction; the test sample is divided into (n-1) equal parts along the two diagonal lines of the test sample; and scrap samples are drilled at marked sampling points are drilled by a drill bit, and in addition, the marking and the collection are carried out, wherein n is an odd number and is greater than or equal to 5. The sampling method disclosed by the invention has the advantages that the product quality essentialization, high-efficiency and low-cost production control requirements are met, and the important guiding significance is realized on the quality monitoring and the process condition improvement of the casting blank production.
Description
technical field [0001] The invention relates to a sampling method and detection method for slab composition segregation, more specifically, the invention relates to a drilling sampling method and detection method for slab composition segregation. Background technique [0002] Carbon and sulfur are important elements to determine the specification and quality of steel products. Carbon plays an important role in the hardness, strength, plasticity and toughness of steel. Sulfur will deteriorate the quality of steel, reduce its mechanical properties, corrosion resistance, and weldability, especially when it exists in the state of iron sulfide, it will cause the phenomenon of "hot embrittlement" of steel, that is, thermal deformation, cracks when working at high temperatures, serious Affect the quality and service life of the product. However, if the process parameters such as water speed, water pressure, and casting speed are unreasonably set during the continuous casting proc...
