直浇道 meaning in English
downsprue
sprue
Examples
- The results show that the heat preservation coating and its proper thickness are favorable to the enhancement of filling mold speed of aluminium alloy ; the higher the pouring temperature is and the larger the ratio of hollow areas of vertical pouring is , the faster the speed of filling mold of aluminium alloy is ; if the mold is too thick or too thin , it may decrease the speed of filling mold ; the proper length and the area of vertical pouring are favorable to the enhancement of the speed of filling mold ; although negatire - pressure may improve filling the speed , too high negatire - pressure may enlarge the flaw in casting
结果表明：保温涂料及一定的涂层厚度有利于提高铝液的充型速度；浇注温度越高、直浇道空心面积率越大，铝液充型速度越快；模样厚度太厚或太薄，均会使铝液充型速度降低；一定的直浇道长度及直浇道面积有利于提高铝液的充型速度；施加负压会使铝液的充型速度大大提高，但负压过大会增大铸造缺陷。 - Considering of the problems exist in practice , large orifice discharge principle is employed to study the pressure distribution of ring runner system , the even ab lity for discharging of gates , the relationship of flow with the position of spr ue and the type of gates . a new design idea about circular runner system of cast is proposed
根据生产中存在的问题，用大孔出流理论研究了环形横浇道系统的压力分布、内浇道出流均匀性及流量与直浇道引入位置和内浇道引入方式之间的关系，提出了圆形铸件环形横浇道系统新的设计思想。
