WZ vs SK vs Seger Cone vs American Standard Cone

The basic test of refractory materials is refractoriness. Different countries have different standards for the refractory industry, and the requirements for refractory materials are also different. Today, we will learn about the international refractory industry’s brand after the fire resistance test.

The refractoriness of refractory materials is tested with a temperature measuring cone. In China, the “WZ (temperature cone)” is followed by one tenth of the cone bending temperature, such as wz125, which means that the bending temperature is 1250 ℃. “SK” is used in Britain and Japan. In addition, there are American standard cone, Seger standard cone, etc. Now let’s look at the comparison table of fire-resistant temperature measuring cones in the international refractory industry for your reference.

Refractoriness is the most basic test of refractory materials. Some experimental tests will be carried out for the production and purchase of refractory materials. Only when the test requirements are met can high-quality refractory materials be produced. More information about refractory materials is in OSYMEN refractory.
