Additive manufacturing technology includes a number of modern processes. With the continuous development of various technologies, the application effect of additive manufacturing technology continues to improve. According to the classification of energy types, it can be divided into “laser forming” and “non laser forming”; According to the shape classification...
Additive manufacturing technology includes computer-aided design technology, material processing and forming technology. At the same time, digital model files need to be used as the basis for technology application, and then special metal, non-metal or medical biological materials are stacked layer by layer in the form of melting, collection,...
Excavators are widely used in mining, civil engineering, water conservancy and national defense projects. Bucket teeth are not only important parts of the machine, but also vulnerable parts. At present, most of the excavators used in Qingdao are imported excavators. Because the geology of this area is different from...
1.Encourage the diversification of investment subjects in the foundry industry Reduce the entry threshold of the foundry industry, reduce unnecessary restrictions, actively encourage foreign and private capital to enter the foundry industry, and support its merger and reorganization of existing foundry manufacturers. In the fierce market competition, the foundry...
Generally speaking, a series of industry standards can bring us advantages in quality management, product quality, marketing and competitiveness. (1) Improve quality management The series of standards are the scientific summary of many years of quality management practice in many economically developed countries in the world. They are universal...
The key points of the development of foundry industry are: on the one hand, further accelerate the pace of enterprise restructuring, eliminate small enterprises with high energy consumption, poor level and serious pollution, integrate industrial resources, and improve the scale and competitiveness of enterprises; On the other hand, it...
The foundry industry in major industrial countries is developing steadily with the development of their national economy. However, from the current development of foundry industry in industrial countries, it does not show a significant increase in output, but mainly lies in the adjustment of product structure, the improvement of...
At present, a considerable number of foundry manufacturers have not cultivated their core competitiveness, seriously lack market competitiveness, passively cope with the competition, retreat step by step, and fall into the dilemma of survival. In addition to the historical legacy and objective environmental factors, the foundry itself mainly lacks...
The test results of 650 semi continuous casting machine equipped with nitrogen protection device are analyzed, which provides evidence for the study of the relationship between nitrogen content and slab surface quality and oxygen content. Take samples from the middle part of the cast red copper ingot. First, remove...
In order to test the application effect of the nitrogen protection device, the power frequency induction furnace is selected as the test equipment. The smelting furnace with horizontal structure can effectively control the tilting process of the converter and discharge slag without side. Combined with the closed chute with...
