Abstract
The invention discloses a copper grade determining method. The copper grade determining method is characterized by adding all to-be-determined copper-containing materials into a refining furnace of which the weight is from 0t to 350t for being smelted, refining the copper-containing materials through a smelting method, and obtaining smelting products; weighing all in-furnace materials, completely and uniformly weighing finished products, semi-finished products, byproducts, waste and furnace slag, and carrying out sampling analyses on copper content; calculating the copper grade according to a formula: copper grade=(finished product physical quantity times grade plus semi-finished product physical quantity times grade plus byproduct times grade plus furnace slag physical quantity times grade plus waste physical quantity times grade)/(recovery rate times copper-containing material physical quantity) times 100 percent. According to the copper grade determining method disclosed by the invention, the accuracy of determining the copper grade is greatly increased, and the copper grade determining method is particularly suitable for determining the copper grade of large-batch copper-containing materials; the defects that the determining accuracy of a copper grade result is difficult to ensure by a spot sampling method as copper scrap is not distinguished according to national standard requirements and that the determining of the copper grade is inaccurate as classified stacking is very difficult to be carried out by a classified sampling method are avoided.
Description
Technical field
The present invention relates to a kind of decision method of copper-contained material copper grade, the copper grade being particularly useful for copper scap judges.
Background technology
The existing judgement to copper scap grade analyzes material copper grade everywhere by eye estimate, spot sampling, then do weighted mean and obtain all kinds of material copper grade in the copper grade of total material, sample analysis material, then adopt average weighted method to obtain the copper grade of material by the gross.Existing copper product position decision method Problems existing in actual production business process is as follows: the copper scap one, on existing market is difficult to accomplish to distinguish by national standard requirement, namely 1# copper, that 2# copper is difficult to separately sorting is clear, and all kinds of species distribution uneven in copper scap, so the method for spot sampling is adopted to be difficult to the accuracy guaranteeing result; Two, the copper scap of existing market contains a large amount of metal, non-metallic impurities, is difficult to accomplish classify and pile up, so adopt the method for classification sampling to be difficult to the accuracy guaranteeing result equally.
Summary of the invention
The object of the present invention is to provide a kind of copper grade decision method, overcome the shortcoming that existing copper grade decision method judges poor accuracy.
A kind of copper grade decision method, is characterized in that: copper-contained material to be determined is all added melting in 0 ~ 350 ton of refining furnace, by smelting process by copper-contained material refining, obtain matallurgical products; All enter stove article all weigh, finished product, semi-manufacture, secondary product, waste product, slag all unification weigh and weigh and sample analysis copper content; Copper grade is gone out by copper grade=(finished product quantity of goods produced × grade+semi-manufacture quantity of goods produced × grade+secondary product × grade+slag quantity of goods produced × grade+waste product quantity of goods produced × grade)/(recovery × copper-contained material quantity of goods produced) × 00% formulae discovery.
Decision method advantage of the present invention is: it improves the accuracy that copper grade judges greatly, is specially adapted to the judgement of copper-contained material copper grade in enormous quantities.Avoid spot sampling method and accomplish that the copper grade that classify and pile up causes judges inaccurate deficiency because requiring not according to national standard the method for the accuracy that differentiation copper scap causes being difficult to guarantee that copper grade result judges and classification sampling to be difficult to.
Embodiment
The invention will be further described below:
A kind of copper grade decision method, is characterized in that: copper-contained material to be determined is all added melting in 0 ~ 350 ton of refining furnace, by smelting process by copper-contained material refining, obtain matallurgical products.All enter stove article all weigh, finished product, semi-manufacture, secondary product, waste product, slag all unification weigh and weigh and sample analysis copper content; The data obtained is recorded in following table.
Copper grade is gone out by " copper grade=(finished product quantity of goods produced × grade+semi-manufacture quantity of goods produced × grade+secondary product × grade+slag quantity of goods produced × grade+waste product quantity of goods produced × grade)/(recovery × copper-contained material quantity of goods produced) × 00% " formulae discovery.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention; make some equivalent alternative or obvious modification without departing from the inventive concept of the premise; and performance or purposes identical, then should be considered as belonging to the protection domain that claims that the present invention submits to are determined.
