Abstract

The invention relates to an automatic production line of directly-reduced ferronickel, which comprises a fine ore stirring machine, a balling device, a wrapping device, a filling system, a tunnel kiln and an unloading device, wherein the the fine ore stirring machine is connected with the balling device through a belt conveyor; the balling device is connected with the wrapping device through the belt conveyor; the wrapping device is connected with the filling system through the belt conveyor; by dint of the filling system, cloth is unloaded conveniently; cloth quantity is precise; automatic filling operation is realized completely; manual loading is substituted; the unloading device makes a material cabin form negative pressure through an induced draft fan, so that temperature ball groups are unloaded into a storage cabin; and operation safety coefficient is increased. According to the invention, the filling system, the unloading device and the tunnel kiln are connected together through a rail, so that a kiln cart is used in a moving manner circularly; therefore, mechanization and automatic production are realized; workload is reduced; and the product quality and production efficiency of the directly-reduced ferronickel are improved.

Description

technical field [0001] The invention relates to a production line for directly reducing ferronickel, in particular to an automatic production line for directly reducing ferronickel. Background technique [0002] The commonly used production process of reducing nickel-iron alloys now includes mixing fine ore, using a ball forming machine to make balls, and after ballizing, coal powder is wrapped outside to form ore balls, which are then loaded into a reduction tank, and passed through a kiln car stepper and a kiln car ferry. The conveyor transports it to the tunnel kiln for sintering and reduction of ferronickel. After leaving the kiln, it is cooled and then unloaded and collected. However, in the existing production line, the loading of ore balls into the reduction tank on the kiln car is manually loaded, and the unloading is also manually unloaded, so the degree of automation is low, and the use of manual operation will reduce the production of the entire production line E...
