Abstract

The invention provides a recovery system for metal in slag of a high-carbon ferro-chrome electric furnace, and relates to a slag separation and recovery system suitable for large and medium-sized high-carbon ferro-chrome electric furnace industries. The recovery system for metal in slag of the high-carbon ferro-chrome electric furnace comprises a conveyor, a jaw crusher, a double-layer vibrating sieve, a cone crusher, a three-layer washing sieve, a tailing dry-discharging and dewatering sieve, a magnetic separator, a slag bin, a metal bin, a sawtooth wave jigger, a rod mill and a ball press machine. The recovery system for metal in slag of the high-carbon ferro-chrome electric furnace has the characteristics of being novel in structure, easy and convenient to machine, small in occupied area, capable of relieving labor intensity, high in production efficiency, capable of reducing labor cost and being matched with environmental protection facilities and the like, and thus is a novel recovery system for metal in slag of the high-carbon ferro-chrome electric furnace which is economical and practical.

Description

technical field [0001] The high-carbon ferrochrome electric furnace slag metal recovery system of the invention relates to a slag separation and recovery system suitable for large and medium-sized high-carbon high-carbon ferrochrome electric furnace factories. Background technique [0002] High-carbon ferrochrome electric furnace slag is an accessory produced in the production process of domestic high-carbon ferrochrome alloy factories. The production of high-carbon ferrochrome alloy uses submerged arc furnace to reduce slag to chromium ore. Because the chromium content in chromium ore is generally only 40 % or so, a large amount of appendages, that is, slag, will be produced. The slag still contains a certain amount of metals with considerable value, mainly ferrochrome alloy. In the past, some metals were mainly recovered by manual and simple mechanical crushing and screening, and the labor intensity was high. The recovery rate is low, and it is difficult to meet the requir...
