[0002] Bottom-blown furnace smelting is widely used in the smelting of non-ferrous metals because of its simple batching process, strong adaptability of raw materials, high smelting intensity, ability to achieve "self-heating smelting", good working environment, no dust, no smoke, excellent technical adaptability, and can be used in combination with a variety of smelting methods. Therefore, bottom-blown furnaces have also been widely promoted and used. The support wheel group is one of the main components of the bottom-blown furnace converter. It bears the weight of the entire furnace body and ensures that the cylinder and rollers can rotate smoothly on the support wheels. In the production process of existing bottom-blown furnaces, materials and splashed slag often fall from the upper part of the furnace body into the support wheel group, causing the support wheel to get stuck. During the converter process, the friction between the furnace body roller and the tugwheel increases, directly causing the converter motor to overload, posing serious equipment hazards. For this reason, we propose a dust prevention device for the support wheel group of a bottom-blown furnace. Utility Model Content
