The mixture of the complexity that green-sand is made up of quartz sand, clay, water, coal dust etc., the direct shadow of performance of green-sand
The quality of casting mold is rung, and then affects the quality of foundry goods.According to statistics, the casting wasted product for having more than 65% is asked due to green-sand quality
What topic caused.
In order to obtain high-quality green-sand, it is necessary to which the performance parameter of green-sand is tested, to process to sand
Cheng Jinhang is effectively controlled.Wherein, compact rate of molding and wet strength are two important performance indications of green-sand.Compact rate of molding refers to molding sand
Volume reducing rate before and after consolidation, when being determined with standard sample cylinder, refers to the slip of sand sample consolidation anterior and posterior height.Wet strength is
The maximum stress that green-sand sample is can bear before destruction.Although the laboratory measurement process of compact rate of molding and wet strength is accurately,
But it is time-consuming longer, therefore, develop the electrical measurement testing equipment of compact rate of molding and wet strength, however, some measuring apparatus structures
Complexity, some measuring apparatus measurement parameters are single, it is impossible to carry out the multiparameter detection of green-sand.
The content of the invention
This utility model is to solve asking for existing green-sand measuring apparatus complex structure and measurement parameter unification
A kind of topic, there is provided the measurement apparatus of green-sand compact rate of molding and wet strength.
