【Abstract】 The soft annealing process of H13 steel are studied in the laboratory. The software of computer aided design is used to calculate the law of temperature variation of workpiece in the production- A reasonable annealing process is designed. Practice of production indication that the new annealing process is reasonal, reliable. The new annealing process meet the needs of production.更多还原
