How to improve the die of cast iron drain pipe reasonably? To purchase the product, we should pay attention to the quality, which is not only related to the material used, but also to the manufacturing process. What should we pay attention to when using moulds? Shandong Ductile Iron Well Cover Factory is here to give you a brief summary!
The reason why the die is used is that it is more efficient, smaller size, size and other errors, manufacturers use it more frequently, it plays a great role. At this time, in order to avoid abnormalities, people need to combine experience and improve it from time to time, so as to follow the requirements of the market to supply products and help manufacturers better benefit.
其中，为保证铸铁排水管质量，模具的性能和使用寿命，都是要引起重视的，而会对这些 造成影响的因素有，耐磨损性能、耐腐蚀性能、摩擦系数、疲劳性能等。要想改善，单纯依赖基 体材料的改进和提高是非常有限的，人们可以尝试对模具表面进行处理，比如涂覆，改变模具表 面的形态、化学成分、组织结构和应力状态，以获得所需表面性能的系统工程。
Among them, in order to ensure the quality of cast iron drainpipe, the performance and service life of the die should be paid attention to, and the factors that will affect these are wear resistance, corrosion resistance, friction coefficient, fatigue performance and so on. In order to improve, it is very limited to rely solely on the improvement and improvement of matrix materials. People can try to treat the die surface, such as coating, changing the shape, chemical composition, structure and stress state of the die surface, in order to obtain the required surface properties of the system engineering.
In addition, nitriding, carburizing and hardening film deposition are widely used in the manufacture of dies。 Different processes have different requirements。 For example, the purpose of die carburizing is mainly to improve the overall strength and toughness of the die, that is, the working surface of the die has high strength and wear resistance。 The manufacturing cost can be reduced by replacing the higher level material with the lower level material through carburizing and quenching。
I wonder if the small arrangement of nodular cast iron well covers in Shandong today will be helpful to you all? If you have anything to add, welcome to our website: comments from http://www。jnwszy。com!
