Industrial energy saving long way to go. As a special abrasives industry, there is a problem in terms of abrasive smelting energy conservation. Existing overcapacity corundum domestic situation, focusing on the next step will be to eliminate the national policy corundum industry backward production capacity CD650 material, shutting down part of the production of energy-intensive small and medium enterprises corundum, out of a small power smelting furnace, encourage competitive enterprises bigger and stronger. Corundum overcapacity caused by price competition is the main reason, some companies get rid of the current popularization of production according to market demand targeted production of marketable products, abrasive calcined CD650 price, plated iridium, etc., have mass market, to meet the mill needs with production not only improves efficiency, returned high-grade production of abrasive materials provided. Surface treatment technology of the mold, by surface coating, surface modification or composite processing technology to change the mold surface morphology, chemical composition, structure and stress state in order to obtain the desired surface properties of systems engineering. From the way of surface treatment, can be divided into: chemical methods, physical methods, physical and chemical and mechanical methods. Although aimed at improving the performance of the new mold surface treatment technologies are emerging, but more in the mold manufacturing applications primarily nitriding, carburizing and hardening film deposition. Die during heat treatment, especially during quenching CD650, to produce volume changes shape warping, distortion, etc., in order to ensure the quality of mold, require heat deformation small mold steel, especially for complex shape of precision molds imported tungsten steel CD650 After quenching difficult to repair, heat deformation degree for more demanding, you should use the micro-deformation of the mold steel. Yong Wei mold steel, tungsten steel imports CD650, CD650 is provided by Yong Wei steel mold.
