A production system for making ad powder from waste aluminum

Abstract

The invention belongs to the field of AD powder production, and particularly relates to a production system for manufacturing AD powder through scrap aluminum. The production system comprises a first storage barrel, an iron collecting barrel, a plurality of blending bins, a batching scale, a grinding miller, a molding press and a stirring machine. The first storage barrel is connected with the batching scale in a sealed mode through a transporting pipeline. A hole is formed in the top face of the transporting pipeline. An opening is formed in one side of the bottom of the iron collecting barrel, and a plurality of magnets of different strengths are arranged in the iron collecting barrel. The iron collecting barrel is connected to the transporting pipeline in a sealed mode through the hole. The batching scale is connected below the blending bins in a sealed mode. The grinding miller is connected below the batching scale in a sealed mode. The stirring machine is connected below the grinding miller in a sealed mode. The molding press is connected below the stirring machine in a sealed mode. Industrial aluminum ash is contained in the first storage barrel. The blending bins are sequentially filled with different ingredients of the AD powder. The technology for preparing the AD powder is simple, the whole production link process is in a sealed state, and no harm is caused to human bodies.

Description

technical field [0001] The invention belongs to the field of AD production, and in particular relates to a production system for producing AD powder by using waste aluminum. Background technique [0002] Fluorite has always been the main slagging agent for steelmaking slagging, but the fluorine in fluorite has great pollution to people and the environment: corroding equipment, causing human bone hardening and osteoporosis; eroding converter lining and ladle lining , Reduce converter and ladle life. With the enhancement of environmental awareness, resource depletion and rising prices, the use of Al-containing 2 o 3 Materials instead of fluorspar are becoming a trend, such as: bauxite is used in converters and electric furnaces instead of fluorspar; 2 o 3 Pre-melted slag and slag wash agent, bauxite instead of fluorite are used in LF, VD, RH; use industrial Al 2 o 3 Powder instead of fluorspar is used in LF, VD and RH; industrial aluminum ash (also known as AD powder, ac...

AI Technical Summary

Problems solved by technology

But wherein all there are very big disadvantages, such as the high iron content of bauxite, the slagging speed is slow and the molten steel temperature is easy to drop in the steelmaking process; Al 2 o 3 , bauxite or industrial aluminum ash elements are relatively simple, explosive and splashing in the steelmaking process, affecting the quality of steelmaking and reducing the safety of steelmaking
