Abstract

The invention discloses smelting equipment for a manganese-silicon alloy. The smelting equipment for the manganese-silicon alloy comprises a smelting furnace. The smelting furnace comprises a smeltingfurnace body. An air blower and an air input pipeline are arranged in the lower portion of the smelting furnace body. The air blower communicates with the air input pipeline. Grates are arranged above the air input pipeline. A combustion chamber is formed above the grates. A fuel supply device is arranged on one side of the combustion chamber. The fuel supply device communicates with the combustion chamber. The combustion chamber is of a cylinder shape. A molten pool is arranged inside the combustion chamber. The molten pool is of a circular truncated cone shape. A fire outlet is formed in the side, away from the fuel supply device, of the combustion chamber. Guide plates are arranged on an inner wall of the combustion chamber. The guide plates are spiral panels. One side of each guide plate is fixed to the combustion chamber. Three or more guide plates are arranged. According to the smelting equipment for the manganese-silicon alloy, heating is more uniform in the smelting furnace adopted; and improvement of the quality of products output is benefited.

Description

technical field [0001] The invention relates to a manganese-silicon alloy smelting equipment, belonging to the technical field of manganese-silicon alloy preparation equipment. Background technique [0002] my country's steel production is currently far ahead of the world with a production capacity of more than 700 million tons, and the demand for ferroalloys has also increased dramatically, but the ensuing pressure on energy, resources, and emissions is huge. With the increasing emphasis on environmental protection in the international community and the shortage of resources such as manganese ore, people are constantly looking for a method of utilizing low-grade manganese ore. For example, a mine is mainly rhodochrosite (MnCO3) and siderite (FeCO3), which are difficult to magnetically separate Separation, the content of TMn is 12-20%, the content of TFe is 12-18%, and the grades of TFe and TMn are only increased by 2-3% after strong magnetic separation. Under the best proc...
