Based on the large orifice discharge theory, the kiss gating system of the casting was designed. 運(yùn)用大孔出流理論設(shè)計(jì)了頂注壓邊澆冒口系統(tǒng)。
For the arch dam which reservoir has no suitable breach to build lasher and has mass flood discharge, opening large orifice for flood discharge has great advantage. 對(duì)于庫區(qū)無適宜埡口可興建泄洪道，而泄洪量又較大的拱壩工程，在壩身中開設(shè)大孔口泄洪具有顯著的優(yōu)越性。
The practice proves that it is feasible to design gating system of heat resistant nodular cast iron casting by using large orifice discharge and moduli calculation method. 證明采用大孔出流設(shè)計(jì)澆注系統(tǒng)，均衡凝固收縮模數(shù)法設(shè)計(jì)耐熱球鐵箱體類鑄件的補(bǔ)縮系統(tǒng)是可靠的。
