摘要	Horizontal continuous casting is a common method to produce copper strip. It is very important to explore the influence of process parameters on the quality of the billet. The influence of drawing speed on temperature field, liquid hole depth and cooling rate in mold was analyzed by numerical simulation, and the influence mechanism of drawing speed on the structure of billet was revealed by process test. The results show that with the continuous increase in the billet drawing speed, the depth of the liquid hole in the mold continues to increase, the cooling rates of the surface and core of billet along the traction direction gradually decrease, and the difference between the two cooling rates gradually decreases. When the drawing speed is 149 mm/min, the cooling rates of the two parts are similar. With the continuous increase in the billet drawing speed, the angle theta between the grain growth direction and the traction direction on the section of the billet increases gradually, the grain growth distance is shortened, the number of grains on the surface of the billet increases, the average grain diameter decreases from 1.96 mm to 1.05 mm, and the overall microstructure uniformity is obviously improved.
