In order to solve the problems of low steel utilization rate and unbalanced blade load in DNV B shipbuilding steel plate, a multi-objective optimization model of steel plate cutting scheme with time attribute was established. The model comprehensively considered the space limitation of motherboard and aimed to maximize the use of DNV B shipbuilding steel plate and load balance rate cutting machine.
Since the scissors fix the seat of the blade for rotary motion, thus completing the cutting action on the DNV B shipbuilding steel plate, high wear resistant steels usually have higher hardness and better wear resistance, wear resistant steels are combined with reasonable alloy composition.
DNV B shipbuilding steel plate high strength mechanical properties are obtained through low temperature cooling and tempering. However, as the hardness and thickness of the steel plate increase, delayed cracks may occur when cutting off the flame of oxygen fuel. Cracks are cracks caused by hydrogen.
Combined with the actual situation of the cutting workshop of the production and processing factory, the main problems of the cutting workshop are understood from the processing capacity and production process of the production design, and the priority programming is put forward, and the design of improving the production efficiency through production efficiency is further verified.
