Embodiment Construction

[0032] specific implementation plan

[0033] The present invention will be further described below in conjunction with accompanying drawing and example.

[0034] This embodiment is an example of a steelmaking plant utilizing the waste steel rating and database building system of the present invention to smelt scrap steel in an electric arc furnace.

[0035] Such as figure 1 As shown, the scrap steel rating and warehouse building system includes a scrap steel rating unit and a scrap steel warehouse building unit. The scrap steel rating unit includes processes such as scrap steel quality measurement, scrap steel volume measurement, and scrap steel composition detection; Processes such as branch records and establishment of stockyard scrap database.

[0036] combine figure 2 , the steel scrap rating unit is composed of a single-girder crane A1, a spreader 2, a steel unloading pit 3, a slide rail 4, a pulley 5 and a mechanical arm 6; the hook of the single-girder crane A is co...

Abstract

The invention discloses a steel scrap rating and database building system and method. The system comprises a steel scrap rating unit and a steel scrap database building unit; the steel scrap rating unit comprises a single-beam crane A, a lifting appliance, a steel unloading pit, a sliding rail, a pulley and a mechanical arm; the database building unit comprises a single-beam crane B, an electromagnetic chuck, a material yard, steel storage tanks, a weighbridge and a computer; and the steel scrap rating and database building method comprises the steps of measuring mass of steel scrap, measuringvolume of the steel scrap, testing components of the steel scrap, classifying the steel scrap and putting the steel scrap into a corresponding tank as well as building a steel scrap variety and quality database. The system disclosed by the invention judges a variety of the steel scrap by obtaining the mass of the steel scrap, estimating the size and testing components, then classifies and stacksthe steel scrap by adopting the steel storage tanks and builds a steel scrap database used for intelligent steel scrap distribution, so that steel scrap identification accuracy can be improved, burning loss of an alloy element is reduced, yield of steel scrap is improved, steel quality is improved, and smelting cost is reduced.

Description

technical field [0001] The invention relates to the classification of scrap steel for steelmaking, in particular to a scrap steel rating and database building system and a method for using the system to carry out scrap steel rating and warehouse building. Background technique [0002] Scrap steel refers to iron and steel scrap that cannot be made into products during the production process of iron and steel factories, as well as iron and steel materials in equipment and components that are scrapped after use. At present, the total amount of scrap steel produced in the world every year is 300-400 million tons, accounting for 45-50% of the total steel output, of which 85-90% are used as raw materials for steelmaking. In addition, steel scrap contains a variety of precious alloy elements, which are of high utilization value. [0003] At present, steel scrap is mainly used in traditional steelmaking processes such as electric furnaces and converters, to adjust the composition o...
