Using advanced equipment and technology, using advanced metallurgical methods and processes, such as refining outside the furnace, electroslag remelting, vacuum processing, multi-directional forging, precision forging, finishing rolling, producing high-quality steel with purity; increasing production uniformity Sexual, high isotropic modules, flat steel, square steel, sheet, etc. Provides productized and refined mold steel products through machining, quenching and tempering treatment. It is the strategic goal of China's mold steel development to transform China's abundant alloy resources and labor resources into the advantages of mold steel products, improve the competitiveness of the international market, and expand exports.
Develop and promote the application of new mold steel
There are many types of new mold steels in China, but the space for developing new mold steels is still large, and some new steel grades need to be improved. For example, the large-scale aluminum alloy castings are increasing, and the development of large-scale aluminum alloy die-casting mold steel is still a top priority. Another example is the rapid development of the construction industry in recent years. The development of ceramics and refractory brick mold steels with low price, high wear resistance and sufficient toughness is also an urgent problem to be solved.
In view of the fact that the new mold steel can greatly improve the service life of the mold, it can solve the production and technical problems in the design, manufacture, use and repair of the mold, and can obtain huge comprehensive benefits. It should vigorously promote the application of new mold steel, and it is expected that the application of new mold steel will be increase yearly. At the same time, we must also pay attention to the use of old steel, through the rational selection of materials, the use of new technology, to foster strengths and avoid weaknesses, to play its greater utility.
Establish a mold material expert system
With the diversification of product varieties, the conditions of mold working conditions are complicated, and the rational selection of materials is more important and urgent. The existing research work has accumulated a large amount of data, on which the performance data of steel grades has been supplemented, the latest achievements and experiences in the field of mold materials technology at home and abroad have been summarized, and the guidance has been established with the help of modern computer technology, which is increasingly widely used. A strong, advanced, reliable and practical expert system for the selection of materials for die steel is imperative.
Establish plastic mold steel series
China's plastics industry is developing rapidly. Plastic products are widely used in agriculture, machinery, chemicals, construction, toys, daily necessities, automobiles, lamps, household appliances, etc. The demand is large and the quality requirements are high. Correspondingly, the demand for plastic mold steel is rapid. Increased, higher requirements are also placed on the performance and process performance of steel. However, Luo Baihui, secretary-general of the International Model Association, pointed out that the current selection of plastic molds is confusing, has no rules to follow, and has great randomness, which affects the service life of the molds, and also affects the quality of plastic products and market competitiveness. It is urgent to develop, introduce and supplement. Improve the steel grade, establish a series of plastic mold steel suitable for China, and make the level of plastic mold steel smelting, quality control, supply, material selection, processing and use a new level.
Strengthen the application of surface treatment technology
Surface treatment can give special surface performance (mainly wear resistance, corrosion resistance, etc.) to the surface of the mold while maintaining the original composition and properties of the mold core, greatly improving the service life of the mold and broadening the application range of the mold steel. It can also replace the high-priced die steel with low-cost die steel, so it has broad application prospects and is valued by countries all over the world. China should vigorously strengthen the basic theory and applied research of surface treatment, using advanced equipment and technology, in order to widely use various types of high-quality surface treatment on the mold.
