Alumina mill linings: ALUBIT 90 | ALDERO industrial supplies

The process of grinding industrial minerals inevitably entails wear and abrasion. So to improve plant productivity and reduce management costs, it is necessary to adopt adequate anti-wear protection. Ceramic mill linings are one of the best solutions. They protect the mill from abrasion, as well as allow higher productivity, particularly in the case of ultrafine grinding.

Rockwell scale - Wikipedia

The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.

Hardness Conversion Calculator - Machining Doctor

Brinell [HB] is one of the most common units used for listing the hardness of steel materials. the test is done with a 10 mm steel ball pressed with 3000 Kgf (6,614 Lbf). Common values for machined materials range from 100 HB for very soft materials up to 650 HB for heat-treated steels.. The advantage of Brinell [HB] over Rockwell [HRC/HRB], is that the whole range is …

Rockwell Hardness Test (Non-distructive Test for Metals)

Rockwell hardness tester gives hardness numbers directly. Minor load of 10 kgf is first applied and then a major load (60, 100, 150 kgf) according to the hardness of the materials, is applied for 5 – 10 sec and after removing both loads gradually, the two observed depths are then subtracted to have the Rockwell hardness number.

The Rockwell hardness number is not the same as the calculated depth differential measurement. Softer metals allow for deeper penetration than harder metals, so the B – A value will always be higher on soft metal test subjects than hard metals. The Rockwell hardness scale number appears inverse to the depth differential calculation.

Guidelines to hardness testing - Hegewald & Peschke

Thus, Rockwell hardness values are calculated by subtracting the penetration depth (per 0.002 mm) from 100 (when using the diamond penetrator) or from 130 (when using any ball penetrator). Example: with a diamond penetrator and a penetration depth of 0.082mm this makes

Tungsten Carbide Hardness Range

To do so requires conversion/equivalents from a practical test method. In the case of tungsten carbide coatings HRC equivalents are very hit and miss and meaningless. As said by Luigi, it seems 91 seems to be a realistic value for HR15N Rockwell superficial scale, but not HRC. If you are considering increasing hardness, you need to be cautious.
