Prevention of burn-on defect on surface of hydroturbine blade casting of ultra-low-carbon refining stainless steel
The burn-on sand is common surface defect encountered in CO2-cured silicate-bonded sand casting of hydroturbine blade of ultra-low-carbon martensitic stainless steel, its feature, causes and prevention measures are presented in this paper. Experiments showed that the burn-on defect is caused by oxid...
