Abstract: In order to solve the problems that there is short of the apparatus of fast testing green sand quality parameters applied in minor foundry enterprise, according to the principle of double power energizing method, a movable fast testing apparatus applied in green sand quality parameters is developed based on 80C196KC single-chip-microcomputer and PC. In the foundry, several greensand quality parameters including compressibility, temperature, active clay content, moisture, permeability and synthetical strength of greensand can be tested fast by the movable apparatus. Stability and accuracy are proved to be high by large-scale experiments.

Key words: Quality of green sand  Intelligent apparatus  Movable testing  Computer
