Under equal flow, both the maximum and minimum theoretical value of gap size were studied and estimation equation was established. The experimental results show that the gap size is a key parameter for the continuous coating extrusion process. Its maximum value （Hmax） is 0.24 mm and the minimum one （Hmin） is 0.12mm. At a gap size of 0.18 mm, the maximum of metal extrusion per unit of time and optimal coating speed could be obtained.展开更多

If the extrusion force, temperature and gap size are too large or small, a dead zone will form in the front of the inlet mold orifice, and the continuous clad extrusion and coating speed will be influenced. Under the condition of equal flow, the maximum and minimum theoretical values of the extrusion force, temperature and gap size are studied. The results show that the gap size is a key parameter that affects the continuous clad extrusion and coating speed when the extrusion force and temperature are kept constant. The maximum value (H_ max) of gap size is 0.50mm and the minimum one (H_ min) is 0.12mm. At a gap size of 0.17mm or 0.29mm, the maximum of metal extrusion per unit time and optimal coating speed can be obtained when the extrusion temperature is 300℃ and the extrusion force is 450kN.展开更多
