There are many examples of such high value-added steel castings at home and abroad, but compared with the mass production of widely used steel castings, after all, the number is small, and the batch is not large, which can not meet the capacity needs of the majority of foundries. Therefore, it is more important to do a good job in the production of existing castings and convert ordinary steel castings into high value-added steel castings. If you produce machine tool parts, automobile parts, construction machinery parts, agricultural machinery parts, mining or locomotive railway parts, but you produce castings with good surface quality, good stability, chemical composition and microstructure stability, mechanical properties meet the technical requirements of service conditions, high dimensional accuracy, less processing allowance, so the weight is relatively light, good machining performance, Stable quality, good uniformity casting, and casting yield is high, low production cost, high efficiency, your steel casting is also high-tech content, high value-added steel casting. China has a considerable number of medium frequency furnace smelting production of steel casting enterprises, the production of automobile parts and machine tools, but the quality is high, the benefit is good, the added value is high, has a great development.
In recent years, although the quality of China's steel casting has been greatly improved, but generally speaking, whether it is the appearance of the surface quality, dimensional accuracy, or the internal chemical composition, microstructure, compared with the industrial developed countries have a big gap, therefore, China's production of steel casting processing allowance is larger, heavier weight, poor dimensional stability, material performance fluctuations. It is difficult to guarantee the stability and uniformity of product quality. This situation has affected the level of China's mechanical products and equipment and the reputation of export products to a certain extent.
Therefore, it is an urgent task for China's casting industry to improve the quality level of steel castings and really become stronger. Due to poor stability and consistency, the average export price of Chinese castings is low. The comparison between Chinese castings and British and European castings in the international market is about 1/2 to 1/30 of the sales price of developed countries due to transportation fees, tariffs and other costs, in fact, the sales price of castings exported by foundries is even lower. After more than 30 years of reform and opening up, China's foundry enterprises have developed greatly. China's casting industry has the most advanced technology and equipment in the world, and China's casting industry is fully equipped with the ability to develop and produce high value-added steel castings.
