USES the advanced equipment and technology, the use of advanced metallurgical methods and techniques, such as refining outside the furnace and electroslag remelting, vacuuming, multidirectional forging rolling, forging and finishing, production purity of high quality steel; Increase in the production of high uniformity and high tropism module, flat steel, square steel, plate, etc. By machining, quenched and tempered treatment methods such as providing products, the quality of steel products. Our country the rich resources and labor resources into steel alloy products advantages, enhance the competitiveness of the international market, expand exports, this is the strategic target in the development of die steel in China.
Research and application of new die steel
There are many different kinds of domestic new die steel, but is still a large space of developing new die steel, and some of the new steel grade performance improvement. Increasingly, such as large aluminum alloy castings, the development of large aluminum alloy die casting die steel is still the top priority. And such as construction developing rapidly in recent years, the development of low price, high abrasion resistance and have a strong enough toughness of ceramics, refractory steel is also an urgent task.
In view of the new steel die service life can be greatly improved, can solve the mold design, manufacturing, use and repair of the production and technical problems, to gain huge comprehensive benefits, should be vigorously promoted application of new die steel, and hopefully the new die steel are increasing year by year. Also should attach great importance to the use of the old steel at the same time, through the reasonable material selection, adoption of new technology, foster strengths and circumvent weaknesses, play a greater effectiveness.
Mold material selection material expert system is established
As the diversification of product variety, complicate mold working condition, reasonable material selection material more important and urgent. Existing research work has accumulated a large amount of data, on the basis of the added sound steel performance data, summarizes the latest achievements in the field of advanced materials technology and experience, with the increasingly widespread application of modern computer technology, to build a strong guidance, advanced, reliable and practical steel material selection of material of expert system is imperative.
Plastic die steel series is established
Plastic industry in China develops very fast, plastic products are widely used in agriculture, machinery, chemical industry, building, toys, daily necessities, automobile, lamps and lanterns, household appliances, etc., high demand, high quality requirements, correspondingly, plastic die steel demand rapid increase, the use of steel performance, process performance is also put forward higher requirements. However, the international mold association secretary general luo hui, points out that the plastic mold material selection is chaotic, nowhere, optional the gender is big, affects the die service life, also affected the quality of plastic products and market competitiveness, need through the development, introduction, improve the grade of steel, to establish suitable for China's series of plastic die steel, plastic die steel smelting, quality control, supplier, material selection, processing and use of level a new step.
To strengthen the application of surface treatment technology
Surface treatment can keep the original composition and properties of the mould the core, on the basis of giving special mould surface using performance (mainly wear resistance, corrosion resistance, etc.), and greatly improve the service life of the mold, broaden the application scope, die steel can also lower prices of steel instead of the die steel with high price, thus has broad application prospect, brought to the attention of the countries all over the world. Our country should vigorously strengthen the surface treatment of the basic theory and application research, the use of advanced equipment and technology, in the hope of variety, high quality surface treatment is widely used in the mold.
