Problems solved by technology

However, the liquid manganese after smelting is cast into ellipsoid or conical columnar metal manganese ingots in the industry. After cooling, it is crushed by manual crushing or jaw crusher. Manual crushing is labor-intensive and costly; The crushing powder rate of the type crusher is large, which leads to a decrease in the metal recovery rate of the product
Directly affect economic benefits

Embodiment Construction

[0011] A method for crushing metal manganese ingots, comprising the steps of:

[0012] 1) Cast molten manganese liquid in an ingot mold with a depth of 200-250mm, a length of 500-2000mm, and a width of 500-2000mm, or cast it in a mold of a continuous casting machine through an insulating ladle. Each mold of the continuous casting machine consists of multiple A cubic mold cavity with a size of 200-250mm;

[0013] 2) The manganese ingot cast in the ingot mold in the above step 1 is naturally cooled, demolded, and then crushed for the first time, and the first crushing is a manganese ingot whose length, width and height are not more than 250mm, enters the classification and screening, and screens out the manganese ingots that reach the particle size of the finished product. The manganese ingots are packaged into the warehouse, and the powdered manganese granules smaller than the finished product size are used as the bottom material of the ingot mould, the fragmented manganese gra...

Abstract

The invention relates to subsequent treatment of metal smelting, in particular to a crushing method of metal manganese ingots. The crushing method of the metal manganese ingots includes the steps of casting in different molds, primary crushing, screening, secondary crushing, screening, packaging and warehousing and the like. The manganese ingots are treated through the process steps, compared withpast manual crushing and the operation that the manganese ingots are directly crushed by using a jaw crusher, the amount of generated powder can be reduced by 7%-10%, and therefore the metal recycling rate of products and the product quality are improved, and economic benefits are directly brought.

Description

Technical field: [0001] The invention relates to subsequent treatment of metal smelting, specifically named as a crushing method for metal manganese ingots. Background technique: [0002] At present, a large amount of washed manganese and crushed manganese are produced in the conventional electrolytic manganese production process. In order to realize resource utilization, the washed manganese and crushed manganese are smelted in an intermediate frequency furnace. On the one hand, resource utilization is realized, and on the other hand, the the quality of the product. However, the liquid manganese after smelting is cast into ellipsoid or conical columnar metal manganese ingots in the industry. After cooling, it is crushed by manual crushing or jaw crusher. Manual crushing is labor-intensive and costly; The crushing powder rate of the type crusher is large, which leads to a decrease in the metal recovery rate of the product. directly affect economic benefits. Invention con...
