Embodiment 1

[0055] This embodiment provides a method for obtaining the impurity rate of broken steel scrap, which is to sample and measure a naturally piled scrap pile, the mass of which is 40 tons. The method for obtaining the impurity ratio of broken steel scrap includes the following steps:

[0056] Use a forklift to suck out or push out a section of the natural pile as a sampling surface; 5.2kg of samples are collected at the four sampling points at the upper end, lower end, left end and right end of the sampling surface.

[0057] After mixing the samples from the four sampling points, use a sieve with a sieve aperture of 2.0mm for screening, and select the impurities in the under-sieve and the impurities in the over-sieve to obtain the total amount of impurities.

Embodiment 2

[0065] This embodiment provides a method for obtaining the impurity rate of broken steel scrap, which is to sample and measure a naturally piled scrap pile, the mass of which is 40 tons. The method for obtaining the impurity ratio of broken steel scrap includes the following steps:

[0066] Use a forklift to suck out or push out a section of the natural pile as a sampling surface; 6.67kg of samples are collected at the four sampling points at the upper end, lower end, left end and right end of the sampling surface.

[0067] After mixing the samples from the four sampling points, use a sieve with a sieve aperture of 2.2 mm for screening, and select the impurities in the under-sieve and the impurities in the over-sieve to obtain the total amount of impurities.

[0068] The quality of the impurities under the sieve was weighed by a weighing device with a weighing accuracy of 1g to be 187g; the quality of the selected impurities was weighed by a weighing device with a weighing acc...

Embodiment 3

[0071] This embodiment provides a method for obtaining the impurity rate of broken steel scrap, which is to sample and measure a naturally piled scrap pile, the mass of which is 40 tons. The method for obtaining the impurity ratio of broken steel scrap includes the following steps:

[0072] Use a forklift to suck out or push out a section of the natural pile as a sampling surface; 5.2kg of samples are collected at the four sampling points at the upper end, lower end, left end and right end of the sampling surface.

[0073] After mixing the samples from the four sampling points, use a sieve with a sieve aperture of 1.8 mm for screening, and select the impurities in the under-sieve and the impurities in the over-sieve to obtain the total amount of impurities.

[0074] The quality of the impurities under the sieve was weighed by a weighing device with a weighing accuracy of 1g to be 152g; the quality of the selected impurities was weighed by a weighing device with a weighing accu...

Abstract

The invention relates to the field of detection methods, in particular to a method for obtaining the impurity rate of crushed scrap steel. The method comprises the following steps: longitudinally cutting along a scrap steel pile to obtain a sampling surface, and shoveling samples at four sampling points of the upper end, the lower end, the left end and the right end of the sampling surface respectively; mixing the samples at the four sampling points, screening by adopting a material sieve with the sieve pore diameter of 1.8-2.2 mm, and selecting out impurities in oversize products to obtain qualified samples; weighing the qualified sample by adopting weighing equipment with the weighing precision of 1g to obtain the mass of the qualified sample, and weighing the mass sum of the screen underflow and the selected impurities by adopting the weighing equipment with the weighing precision of 1g to obtain the total amount of the impurities; and calculating the impurity rate of the crushed scrap steel according to the total impurity amount and the qualified sample mass. According to the method for obtaining the impurity rate of the crushed scrap steel, the quality condition of the crushedscrap steel can be simply, truly, accurately and objectively inspected.

Description

technical field [0001] The present application relates to the field of detection methods, in particular, to a method for obtaining the impurity rate of broken steel scrap. Background technique [0002] Shredded steel scrap is processed from various raw materials such as automobile body, unified scrap steel, bicycle frame, motor disassembled parts, small scrap steel, etc. If the content is too high, it will affect the use of broken steel scrap in the later stage. Therefore, it is necessary to evaluate and calculate the impurities in broken steel scrap. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a method for obtaining the impurity ratio of broken steel scrap, which aims to quickly and accurately obtain the content of impurities in broken steel scrap. [0004] This application provides a method for obtaining the impurity rate of broken steel scrap, which is used to obtain the impurity rate in broken steel scrap,...
