Casting a direct impact on the quality of the property itself dock cable channel processing, which determines the hardness value is an important indicator of the casting process. 1. Brinell hardness: mainly used to measure the hardness of the pier castings, forgings, non-ferrous metal parts, hot-rolled and annealed blank piece of cable tray manufacturers, measuring range ≯HB450. 2. Rockwell hardness: HRA is mainly used for high hardness specimens dock cable trough, measured higher than HRC67 hardness and surface hardness than the material, such as carbide, nitride steel, measuring range HRA> 70. HRC mainly for steel member (such as carbon steel, tool steel, alloy steel, etc.) after quenching or tempering hardness measurement, measurement range HRC20 ~ 67. 3. Vickers hardness: thin pieces and used to determine the hardness of the steel parts, can also be used to determine the carburizing, cyanide, nitrogen and other parts of the surface hardening hardness. Casting weight and size range are very wide, weighs only a few grams of the lightest and heaviest up to 400 tons dock cable trough price, the thinnest wall thickness of only 0.5 mm, the thickness may be more than one meter in length by a few millimeters to ten meters, can meet the requirements of different industrial sectors. Casting quality has a great impact on the performance of mechanical products. For example, wear resistance and dimensional stability of the casting machine, a direct impact on the accuracy of the machine to maintain life; all kinds of pump impeller, housing and hydraulic cavity size, accuracy and surface roughness profile, directly affect the pump and efficiency of the hydraulic system, the development of energy consumption and cavitation etc; intensity combustion engine block, cylinder head, cylinder, piston rings, exhaust pipes and other castings and resistance to spalling resistance, direct impact on the working life of the engine.
