Steel Casting The Effect Is Very Big
Steel castings as a very important metal parts, the role is very large. Its application surface is not only broad, the demand is also each year rapid increment. Facing the competition of the domestic industry, excellent enterprises to continuously innovate and accurate production technology to win a more solid market; in the face of foreign markets, although our steel castings still have a gap, but China's steel castings industry has not stopped, has been in efforts, although there is a gap but the market demand is overwhelming. China's steel castings industry also has a very large space for development.
Actively adjust the industrial structure, and constantly expand the application of products, and constantly absorb the advantages of domestic and foreign competitors, Steel Casting take its essence, go to its dross, steadily in the continuous development of the competitive torrent. For the development of steel castings industry in China, the industrial structure changes the development of steel casting technology. Because, the steel castings adopt what kind of technological progress way does not deviate from its national conditions. China's basic national conditions are large population, abundant labor force, but capital scarce, per capita resources have little.
The steel castings industry has been developed as a labor-intensive industry, and the relevant policies of the country should be supported. At the same time, the steel industry in technology development should focus on the development of a variety of resources to improve the efficiency of the use of technology, such as energy-saving technology, consumption reduction technology and resources protection, Steel Casting reuse technology. Vigorously develop labor-intensive economy, in order to use labor resources intensively, save capital and natural resources. In another perspective, the development of labour-intensive economies is not a technological advance, which requires that technological progress be conducive to the full use of labour and the conservation of capital and natural resources to maximize the efficiency of the use of resources.
Steel castings to make shape, shape, core method: The use of real-like wood as the operation of the side of the rack-like. In the wood surface layer of steel, Steel Casting wood and soil combined with the production method to achieve the formation of the frame inner core box, to achieve the quality of appearance requirements, saving wood and time. The casting process of medium sand and core sand making material is very important. In order to make the quality of the rack meet the requirements, the use of resin as the type, core sand. That is to ensure that sand and sand core quality requirements, but also to improve productivity. The outer surface of the cast steel is added with cold iron, which is also designed to realize the solidification sequence of castings, Steel Casting and the quality requirements of castings are better ensured.
The design principle is that the liquid metal can rise steadily in the form. Resin sand to avoid high-temperature baking, rapid pouring. Pouring the flow should be timely increase. When machining large gears, the production of steel castings is relatively simple, and in large-scale gear machining, the operation method of steel castings is to insert the workpiece from the inner sleeve hole of the tailstock, Steel Casting then clamp the head and the end of the tail seat respectively, and the large gears are segmented. The size of large gears can also be changed by adjusting the distance between the clamping head and the tailstock in the large gear machining.
The cost of large-scale gear machining is lower, and the quality of steel castings is very strict in the process of production. Therefore, it can ensure that large-scale gear processing products produced by the high quality, and will not because of rigidity and other causes of deformation and bending and other phenomena, Steel Casting and large-scale gear processing using casting technology also makes the service life of large-scale gears longer, so trusted by consumers.
