Iron ore sampling optimization and quality fluctuation early warning system and method

Abstract

The invention discloses an iron ore sampling optimization and quality fluctuation early warning system, which relates to the technical field of iron ore quality inspection, and comprises a parameter input module, a data calling module, a historical data sufficiency inspection module, a deviation value prediction module, an arrival port inspection value fluctuation rate prediction module, a qualityfluctuation category prediction module, an inspection frequency distribution module and a quality early warning module, wherein the modules above are logically connected in sequence. According to themethod, historical test data is used as a prediction basis of iron ore quality fluctuation, a sampling mechanism is optimized to reduce sampling errors and construct a quality fluctuation early warning system, and a prediction result is rigorous and reliable.

Description

technical field [0001] The invention relates to the technical field of iron ore quality inspection, in particular to an iron ore sampling optimization and quality fluctuation early warning system and method. Background technique [0002] The quality fluctuation of iron ore is directly related to trade risk and environmental risk, involving huge economic and social benefits. There is currently no uniform evaluation standard for iron ore quality, and only the relevant binding clauses of the trade contract are used as the evaluation basis. Due to the differences in raw ore environment, mining process, ore mixing mode and other aspects, it often leads to large differences in the quality of iron ore. For every percentage point difference in iron ore quality, the price of a 100,000-ton ship of iron ore will vary by hundreds of thousands of dollars. If the impurity elements such as sulfur and phosphorus in iron ore are high, it will not only cause damage to smelting equipment, bu...

Problems solved by technology

Zhong Ying and others analyzed the content of toxic and harmful elements in 132 batches of iron ore imported from Shenzhen Port, and found that the content of Cd and As in iron ore from some places of origin was relatively high, and there was a risk of environmental pollution. appropriate controls

Zhang Niaofei and others analyzed harmful elements in 229 batches of imported iron ore at Majishan Port in Shengsi, Zhejiang Province. The results showed that the contents of S, Cl, As, and Cd in imported iron ore from some countries exceeded the relevant standards. upper limit, risk of contamination

However, these documents only analyzed the excessive content of toxic and harmful elements, and did not use it as the basis for optimizing the sampling plan
