| 陶瓷钢管与传统的钢管、耐磨合金铸钢管、铸石管以及钢塑、钢橡管等有着本质性区别。陶瓷钢管外层是钢管，内层是刚玉。刚玉层维氏硬度高达100—1500（洛氏硬度为90-98），相当于 钨 钴硬金。耐磨性比碳钢管高20倍以上，它比通常粘接而成的刚玉砂轮性能优越得多。现在刚玉砂轮仍是各种磨床削淬火钢主要砂轮。陶瓷钢管中刚玉层可把刚玉砂轮磨损掉。陶瓷钢管抗磨损主要是靠内层几毫米厚的刚玉层,其莫氏硬度为9,仅次于金刚石和碳化硅，在所有氧化物中，它的硬度是最高的。 There are essential differences between ceramic steel pipe and traditional steel pipe, wear-resistant alloy cast steel pipe, cast stone pipe, steel plastic pipe and steel rubber pipe. The outer layer of ceramic steel pipe is steel pipe, and the inner layer is corundum. The Vickers hardness of corundum layer is as high as 100-1500 (Rockwell hardness is 90-98), which is equivalent to tungsten cobalt hard gold. The wear resistance is more than 20 times higher than that of carbon steel pipe, and its performance is much better than that of corundum grinding wheel. At present, corundum grinding wheel is still the main grinding wheel for grinding quenched steel. The corundum layer in the ceramic pipe can wear off the corundum grinding wheel. The wear resistance of ceramic steel pipe mainly depends on corundum layer with thickness of several millimeters. Its Mohs hardness is 9, which is second only to diamond and silicon carbide, and its hardness is the highest among all oxides. |
