Embodiment 1

[0009] Electrolytic manganese flakes are used as raw materials, and electric furnace is used for smelting. Electrolytic manganese flakes and mold slag are charged at the same time. The amount of mold slag charged is 11% of the total furnace capacity, and the mold slag is composed of 24% fluorite and 76% lime. After the furnace is installed, start to send electricity and heat up until it is completely melted. When the furnace material is completely melted, the slag material will float to the surface of the melt, adjust the temperature to 1420±10°C, and start the deoxidation operation. The deoxidizer uses 200 mesh pure magnesium powder and sprinkles it in batches. Pour into the melt, sprinkle the deoxidizer and keep it for 5 minutes, stir evenly and tap out the steel. When tapping the steel, the melt and mold slag are mixed out and poured into the tundish with the lower outlet. After the mold slag floats up, it is poured into the water-cooled iron ingot mold from the tundish, so...

Embodiment 2

[0010] Example 2: Use metal manganese powder as the raw material and use electric furnace for smelting. After the metal manganese powder charge is loaded into the furnace, start to send electricity to increase the temperature and melt it. During the melting process of the charge, you can see the molten pool at the lower part of the crucible, add the protective slag material, and put the protective slag into it. The amount is 20% of the total furnace capacity, and the mold slag material is composed of 30% fluorite and 70% lime. When the charge is completely melted, the slag floats to the surface of the melt, adjust the temperature to 1530±10°C, and start the deoxidation operation. The deoxidizer uses 200 mesh pure magnesium powder, which is sprinkled into the melt in batches. After the deoxidizer is sprinkled, keep 8 minutes, stir evenly and tap out the steel. When the steel is tapped, the melt and the mold slag are mixed, and poured into the tundish with the lower outlet. Afte...

Abstract

The invention provides a low-gas content metal manganese ingot and a preparation method thereof. The metal manganese ingot is prepared by adopting electrolytic manganese or metal manganese powder as the raw material; covering is carried out by adopting covering slag containing fluorite and lime in an electric furnace smelting process; deoxidation is carried out by using a pure magnesium powder; and meanwhile, calcium in the covering slag is utilized to remove sulfur, wherein the covering slag contains 20-60wt% of fluorite and 40-80wt% of lime. The total content of nitrogen, hydrogen and oxygen of the metal manganese ingot prepared by the method is less than 800ppm and is less than that of metal manganese sheets produced by an electrolytic process, metal manganese pellets produced by a forging rolling process and metal blocks produced by the traditional smelting process. The invention can be widely used for producing special metallurgic products.

Description

technical field [0001] The invention relates to a metal manganese ingot with low gas content and a preparation method thereof. technical background [0002] Metal manganese is usually used as an alloying additive in the metallurgical industry. In conventional iron and steel products, due to the limited amount of manganese added, its gas content has no obvious impact on the quality of the alloy. With the development of science and technology, a large number of alloy materials based on manganese have appeared by using the special physical and chemical properties of manganese, such as manganese-based vibration damping materials, manganese-copper precision resistance alloys and manganese-based high thermal expansion alloys. The content of manganese in these alloys is very high, and some content is as high as 80%. For manganese-based alloys, the gas content must be reduced to a very low level, otherwise it is difficult to smelt and process. It is determined that the total gas co...
