[0002] Hot metal ladle cars are also called hot metal transport cars. Hot metal ladle cars widely used at home and abroad are mainly divided into two types: ordinary hot metal ladle cars and torpedo-type hot metal ladle cars. Torpedo-type hot metal ladle cars are long and torpedo-shaped hot metal ladle cars used in large blast furnaces, also known as mixed iron cars. At present, the running parts of torpedo-type mixed iron cars on the market are all unpowered structures, and the operation mode is passive walking mode, that is, they must be towed or pushed by rail traction locomotives. Because they cannot walk autonomously, they are very inflexible to use, have great limitations, occupy a large space, and cause serious pollution.
