| Abstract: | It is difficult to cast the radiatior with air-tightness requirements in investment casting.Through analysis of structure of the radiator,some countermeasures,including design of gating system,filling velocity,pouring temperature of shell mold,super-heating of liquid steel,were conducted to improve the air-tightness of radiator and to decrease welding-repair,increasing the qualified rate of the investment casting radiators. |
