1 Introduction to the production process 1.1 Determination of process options The factory than the water unit method and long-term bench two process options. The latter has the following advantages: (1) Flexibility to meet the sleeper length specifications and more, buried casing and more, buried casing position accuracy requirements of higher product quality requirements. (2) Make full use of the existing facilities in the factory and invest 50% more than the water-flow generating units in the province. (3) The production of ready
