Sampling method and device and casual inspection method and device for scrap steel briquettes

Abstract

The invention provides a sampling method for scrap steel briquettes. The sampling method comprises the following steps: S1, acquiring loading information of the scrap steel briquettes; s2, based on the loading information, generating sampling three-dimensional coordinates of the scrap steel briquettes; s3, randomly generating sampling coordinate points in the sampling three-dimensional coordinate range; s4, judging whether scrap steel briquettes exist at the coordinate points or not; s5, if the steel scrap pressing blocks exist at the coordinate points, regarding that the steel scrap pressing blocks at the positions of the coordinate points are pressing blocks to be inspected, and carrying out follow-up inspection; and S6, if no scrap steel briquettes exist at the coordinate points, re-determining the briquettes needing to be sampled. According to the method, the position of the pressing block is accurately positioned through three-dimensional coordinates, human interference factors are eliminated, random sampling in a real sense is achieved, and the quality condition of the steel scrap pressing block of the whole vehicle can be truly, accurately and objectively detected. The invention further provides a sampling device, a sampling inspection method and sampling equipment of the scrap steel briquettes and a storage medium.

Description

technical field [0001] The application relates to the field of scrap steel briquette processing, in particular, to a sampling method, a sampling device, a sampling inspection method, sampling equipment and a storage medium for scrap steel briquette. Background technique [0002] As a green and environmentally friendly renewable resource, scrap steel is an important raw material in iron and steel smelting. Scrap steel briquette is a kind of packed block scrap steel. Because of its high density and small size, it is widely used in converters, iron ladles, blast furnaces, In smelting processes such as electric furnaces, to reduce the "iron-steel ratio" and increase production capacity. [0003] According to different packaging materials, scrap steel briquettes are divided into scrap steel briquettes (packed and formed from all-in-one wire rods, coil snails or threaded steel bars), industrial briquettes (all kinds of automobile shells, cold-rolled edge materials, industrial thin...

Problems solved by technology

Some dishonest enterprises even have loopholes in the sampling inspection method of scrap steel briquetting, maliciously mixing mineral powder, sulfuric acid slag, iron slag and other impurities or harmful substances into the scrap steel briquetting raw materials, and even deliberately Doping and making fakes will bring huge losses to the user unit

Therefore, it is particularly important to sample and inspect the purchased scrap steel briquettes. At present, most enterprises use manual sampling in the sampling process, which will inevitably have human interference factors, and the randomness of sampling inspection cannot be guaranteed. In addition, when the briquettes enter the factory, how to ensure accurate acquisition of loading information and sampling quantity, which has a significant impact on the accurate and objective inspection of the quality of the vehicle scrap briquettes
