The rise of new energy vehicles has led to the development of related supporting industries. It is in this situation that integrated casting came into being, but it also puts forward new requirements and challenges for enterprise cost management. The author has conducted an in-depth study on the cost...
1. Production of automobile aluminum alloy wheels In order to fully demonstrate the superior performance of wheel hub and apply it to automobile production, aluminum alloy has become the preferred material for automobile wheel manufacturing, and the output of aluminum alloy has increased year by year. Through the analysis...
1. Development origin of automobile aluminum alloy wheels The manufacturing of aluminum alloy wheel in foreign countries has experienced the development process from sand casting to aluminum alloy integral wheel, which was widely used in ordinary cars after World War II. The rapid development of automobile aluminum alloy wheel...
The wheel hub is the key to the car styling. The performance of the wheel hub itself is directly related to the overall performance of the vehicle and is an important guarantee for the personal safety of passengers. In recent years, aluminum alloy wheels have been widely used in...
1. Microstructure The microstructure photos of titanium containing aluminum alloy ADC12-0.25Ti samples cast at different temperatures are shown in Figure 1. It can be seen from Figure 1 that with the pouring temperature increasing from 690 ℃ to 750 ℃, the grain size of the sample is basically unchanged...
The new aluminum alloy ADC12-0.25ti containing titanium for automobile parts is taken as the research object. The chemical composition of the alloy sample is shown in Table 1. YFL-50 induction melting method is used to prepare alloy samples. The melting temperature is 720 ℃. After slag removal, it is...
In the situation of fierce market competition, under the premise of ensuring product quality, energy saving and consumption reduction is an important means for enterprises to improve economic benefits. No matter whether quenching + high temperature tempering or energy-saving waste heat quenching + high temperature tempering are used, the...
ADC12-0.25ti aluminum alloy samples for automotive castings were prepared at different pouring temperatures. The microstructure, fluidity and hot cracking resistance of the samples were tested and analyzed. The main conclusions are as follows: (1) Pouring temperature has an obvious effect on the microstructure and casting properties of adc12-0.25ti aluminum...
The metallographic microstructure of the finished automobile connecting rod shall be uniform fine grain structure, and no sheet ferrite is allowed. The microstructure of automobile connecting rod of general quenched and tempered steel is tempered sorbite, while the microstructure of automobile connecting rod of non quenched and tempered steel...
In the past, the engine connecting rod was made of medium carbon steel or medium carbon alloy steel after quenching and high temperature tempering. The hardness after treatment was generally 228-269hbs. However, there are some defects such as difficult machining, poor surface quality, easy crack in quenching, and high...
