In order to overcome the disadvantages of oft-repeated rail removing and high exepnditure caused by the conventional railway transtportation of slag in steel plants, it is very necessary to develop the wheeled slag pot carrier. Currently, the hydromechanical drive for the imported slag pot carrier has been used. However, a product series of hydraulic driving elements has not been taken shape in China. The price of hydraulic driving elements used to equip the entire carrier is so high that it is difficult to be acceptable for China's steel plants. Therefore, the extensive feasibility, calculation and proof of mechanical drive for the slag pot carrier have been made, and 4 sets of 32t Model LC2-35 mechanically-driven slag pot carriers. It has been proved that its performance is comparable to that of similar hydraulically-driven slag pot carriers made in foreign countries.
