Treatment system for separating manganese-iron alloy slag iron and separating method

Abstract

The invention provides a treatment system for separating manganese-iron alloy slag iron. The treatment system comprises a slag fishing machine, a crusher, a first drum sieve, a ball mill, a second drum sieve and a washbox which are sequentially arranged. A first belt conveyer is arranged between the crusher and the first drum sieve. A second belt conveyer is arranged between one discharge port of the first drum sieve and the ball mill, and a fifth belt conveyer is arranged on the other discharge port. A third belt conveyer is arranged between the ball mill and the second drum sieve, a fourth belt conveyer is arranged between one discharge port of the second drum sieve and one side of the washbox, and a sixth belt conveyer is arranged on the other discharge port. A fine powder pond and a tailing pond are arranged on the other side of the washbox. First separation of the slag iron is achieved through the crusher and the first drum sieve, second separation of the slag iron is achieved through the ball mill and the second drum sieve, third separation of the slag iron is achieved through the washbox, the slag iron mixture is subjected to three times of separation in sequence, it is guaranteed that the slag iron is fully separated, and the finished product quality is high.

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a treatment system and a separation method for separating ferromanganese alloy slag and iron. Background technique [0002] Manganese is an indispensable element in steel production, and almost all steels contain a certain amount of manganese. First of all, manganese has a relatively high affinity with oxygen and sulfur, so manganese is a deoxidizer and desulfurizer for molten steel. Secondly, manganese is used as an alloying agent, and manganese is added into molten steel as an alloying element to alloy the steel, thereby improving the mechanical properties of the steel, increasing the strength, hardness, ductility, toughness and wear resistance of the steel. Thirdly, manganese can improve the performance of cast iron, adding manganese to cast iron can improve the physical and mechanical properties of castings, such as increasing the hardness and wear resistance ...

AI Technical Summary

Problems solved by technology

When the basicity is greater than 1.5, the viscosity and refractory properties of slag will increase, resulting in difficulty in the separation of slag and iron

[0004] In the production of ferromanganese alloy, since the slag is mostly acidic slag with high viscosity, the interface between the manganese alloy melt and the smelting slag after being discharged is not clear, which makes it difficult to separate the slag and iron. , the product slag inclusion rate is high, the metal recovery rate is low, and the product quality is poor
