单种铸件收得率的计算

CALCU LATION OF SINGLE CASTING OBTAIN RATE

本文以理论上推导出了铸造过程中四项主要参数:收得率η,成品率α,工艺出品率β和铁水利用率ν之间的数学关系式η=αβν/1-ν(1-αβ)同时论述了该关系式对铸造过程中的计划、定额、成本、价格、及设计、工艺、管理的指导作用.

The essay deduced mathematics formula between four main parameters obtain rate η, fin-ished product rate α, technological product rate β, moltten iron utiliztion rate γ, from theory η=αβγ/1-γ(1-αβ)Meantime it discussed directive action of the formula in casting process on plan, quota, cost, price,design, technology and management.
