浇注系统的功能主要是用于对金属液填充铸型的速度进行控制以及对铸型填充时

The function of the pouring system is mainly to control the speed at which the molten metal fills the mold and to control the filling time of the mold, to ensure the smoothness of the molten metal into the mold, reduce the flow of liquid injection, and cause erosion to the mold during pouring At the same time, it prevents other impurities from flowing into the cavity, does not bring in gas during the pouring process, and makes the cooling time of the casting meet the requirements of the solidification standard as much as possible. The source of the parameters of the gating system is mainly based on the area of ​​the inner gate and the total area of ​​the horizontal gate and the area of ​​the straight gate. The open type and the closed type of the pouring system are mainly selected by the above-mentioned area ratio. The calculation standard for the cross-sectional area is based on the area ratio of the pouring liquid flow pouring vertical contact. When the gate area is minimized in the president, the pouring system will fill up the molten metal in a short time. The pouring and filling in a short time provides time isolation for the entry of impurities, and there is not enough time for impurities Into the filling container, so this method is also called closed pouring. It has a wide range of applications and is generally preferred. When the mouth of the container receiving the pouring is smaller than the area of ​​the pouring liquid column, this pouring process will make the molten metal pouring unable to fully fill the pouring system in a short time, so this pouring method is also called an open pouring system, generally the system Mainly used in special processes.

The function of the pouring system is mainly used to control the speed of the metal liquid filling casting and the casting filling time, to ensure the smooth and smooth entry of the metal liquid into the casting, to reduce the flow of injection fluid, to the casting at the time of pouring to prevent other impurities from flowing into the cavity, will not be brought into the gas during the pouring process, and the cooling time of the casting as far as possible in line with the solidification standard requirements. The parameters of the gating system are mainly based on the area of the ingate and the total area of the gate and the area of the direct gate. The open and closed gating system is mainly selected by the area ratio mentioned above, and the calculation criteria for the cross-sectional area are the proportion of the area in vertical contact with the pouring fluid flow. When the ingate in the president area is minimized, the pouring system in a very short period of time will make the metal liquid filled, a short period of time pouring fill for the entry of impurities to provide time isolation, impurities do not have enough time to enter the filling container, so this way is also called closed pouring, a wide range of applications, generally are preferred. When the container port receiving pouring is smaller than the area of the pouring column, such a pouring process will make the metal pouring can not fully enrich the pouring system in a short period of time, so this gating method is also called open pouring system, the system is generally used in special processes.

The function of gating system is mainly used to control the filling speed of molten metal and the filling time of the mold, ensure the smooth and smooth entry of molten metal into the mold, reduce the flow of the injection liquid, and prevent other impurities from flowing into the mold cavity while flushing the mold during pouring, so as not to bring in gas during pouring, and make the cooling time of the casting as long as possible Meet the requirements of solidification standard. The parameters of gating system are mainly based on the area of inner gate, the total area of transverse gate and the area of vertical gate. The open type and closed type of gating system are mainly selected according to the above mentioned area ratio, and the calculation standard of sectional area is the area ratio of vertical contact of pouring liquid flow. When the inner gate area is minimized, the gating system will fill the molten metal in a very short time. The pouring filling in a short time provides time isolation for the entry of impurities, and the impurities do not have enough time to enter the filling container. Therefore, this method is also called closed pouring, which has a wide range of applications and is generally preferred. When the opening of the container receiving pouring is less than the area of the pouring liquid column, this pouring process will make the molten metal pouring unable to fully fill the gating system in a short time, so this pouring method is also called open gating system, which is generally used in special processes.<br>
