Refractory mud cone penetration tester

Refractory mud cone penetration testerOverview

The refractory mud cone penetration tester is based onGB/T22459.1Refractory MudPart: Consistency Test Method (Cone Penetration Method) "Developed and produced a cone penetration tester, supplied by Hebei Dahong Experimental Instrument Co., LtdforConsistency test of refractory slurry.

Cone penetration refers to 25Under the condition of ℃, release a certain mass of cone from the cone penetrometer, and the cone will5sThe depth of penetration into the tested sample during the falling process. The unit of cone penetration is0.1mmRepresenting, such as cone insertion
depth30.0mmCone penetration 300.

Refractory mud cone penetration testerPerformance characteristics:

1． The instrument can allow experiments to be conducted in different directions, and can even be used in a constant temperature water bath

2． Digital display depth measurement mechanism, easy to use, good repeatability, and high measurement accuracy

3． The bracket can move at two speeds: fast and micro, making it easy to align the needle with the surface of the specimen during testing operations

4． Equipped with a table level adjustment mechanism, easy to adjust

5． Equipped with a mechanism for manually releasing needle inserts, it ensures normal operation even when automatic release time is not in use

Refractory mud cone penetration testerTest steps

1Dry powder mud.Weigh the sample and place it in a blender. Add water (or specified liquid) according to the manufacturer's instructions and mix evenly. Record the amount of liquid added and place the mixed mud15 min,Or operate according to the manufacturer's instructions. For pre mixed mud.Should be in its original form(as received)”Conduct testing in the current state.

2Measure the temperature of the mixed mud until1℃。

3Place the cone penetrometer vertically and install a clean and dry cone.

4Fill the sample box with mixed refractory slurry.Scrape the surface of the sample flat with a level ruler.Place the sample box on the test bench.

5Adjust the position of the cone to make it just in contact with the surface of the refractory slurry at the center of the sample box. Push down the dial measuring rod.Make its lower end in contact with the top of the collision rod. Adjust the pointer to zero.

6Press the start button and hold5 s.Allow the cone to sink freely. Release the button and push down the dial measuring rod until its lower end contacts the top of the collision rod. Read the values on the dial until0.1 mmAs the viscosity of refractory slurry.

7Lift the dial measuring rod and cone. Clean the cone and press 3~ 6Repeat the measurement once according to the regulations.
