Embodiment 1
[0019] For the silicomanganese high-efficiency absorption alloy ball of the present invention, the weight ratio of each component raw material can be: 55 parts of silicomanganese alloy, 10 parts of ferrosilicon, 10 parts of manganese ore, 5 parts of high alumina cement, and 0.5 part of binder . The chemical composition of the silicomanganese high-efficiency absorption alloy spheres can be contained in mass percent: Mn 55%, Si 13%, S ≤ 0.5%, P ≤ 0.3%, and the remainder is impurities.
[0020] The method for preparing the above-mentioned silicomanganese high-efficiency absorption alloy balls is: firstly take the silicomanganese alloy, ferrosilicon and manganese ore to clean and remove impurities, and wash the silicomanganese alloy with clear water to prevent harmful impurities from mixing into the raw materials and entering molten steel for smelting. Affect the quality of molten steel for smelting, and break into particles with particle diameter≤3mm respectively; After adding 5...
Embodiment 2
[0022] For the silicomanganese high-efficiency absorption alloy ball of the present invention, the weight ratio of each component raw material can also be: 57 parts of silicomanganese alloy, 13 parts of ferrosilicon, 15 parts of manganese ore, 6 parts of high alumina cement, and 1.2 parts of binder. share. The chemical composition of the silicomanganese high-efficiency absorption alloy balls may also be contained in mass percentages: Mn 57%, Si 15%, S≤0.5%, P≤0.3%, and the remainder is impurities. The preparation method of the silicomanganese high-efficiency absorption alloy ball is basically the same as that of Example 1, the only difference being that the amount of water added during the mixing process is controlled at 10% of the total weight of the dry material.
Embodiment 3
[0024] For the silicomanganese high-efficiency absorption alloy ball of the present invention, the weight ratio of each component raw material can also be: 60 parts of silicomanganese alloy, 15 parts of ferrosilicon, 20 parts of manganese ore, 8 parts of high alumina cement, and 2 parts of binder share. The chemical composition of the silicomanganese high-efficiency absorption alloy ball can also be contained in mass percent: Mn 60%, Si 18%, S≤0.5%, P≤0.3%, and the remainder is impurities. The preparation method of the silicomanganese high-efficiency absorption alloy ball is basically the same as that of Example 1, except that the amount of water added during the mixing process is controlled at 15% of the total weight of the dry material.
[0025] The silicon-manganese high-efficiency absorption alloy ball of the present invention has been proved through repeated trials that it can completely replace the traditionally used alloys such as ferrosilicon, high-carbon ferromanganes...
