Abstract
A foundry sand inspection method according to an aspect includes: charging foundry sand into a test tube; measuring compactability (CB) of the foundry sand while compressing the foundry sand in the test tube to produce a test piece; and compressing the test piece and measuring a compressive strength of the test piece.
Claims9
A foundry sand inspection method comprising:
- charging foundry sand into a test tube;
- measuring compactability (CB) of the foundry sand while compressing the foundry sand in the test tube to produce a test piece;
- and
- compressing the test piece and measuring a compressive strength of the test piece.
1 more element
An inspection device comprising:
- a test tube extending in an axial direction;
- a chute configured to supply foundry sand into the test tube;
- a pressing rod including a pressurizing plate movable in the axial direction in the test tube;
- a cylinder being connected to the pressing rod and having a piston rod movable forward and backward in the axial direction;
- a load sensor disposed between the pressing rod and the piston rod;
- and
- a control device configured to control operations of the chute and the cylinder,
- wherein the control device includes:
- a charge control unit configured to control the chute to charge the foundry sand into the test tube;
- a CB measurement unit configured to measure compactability (CB) of the foundry sand in the test tube while compressing the foundry sand with the pressurizing plate to produce a test piece;
- and
- a compressive strength measurement unit configured to measure the compressive strength of the test piece based on a load measured by the load sensor when the test piece is compressed to be broken.
