Embodiment Construction

[0015] When adopting production method of the present invention to implement,

[0016] The first step is to select high-quality raw materials, including: Fe≥99.98% by weight of pure iron, C≤0.012% by weight of carbon, 12.00≤Ni≤16.00% by weight of nickel, 0.05≤Ti≤0.40% by weight Percentage of titanium, 4.00≤Mo≤6.00% by weight of molybdenum, 9.00≤Co≤12.00% by weight of cobalt;

[0017] In the second step, vacuum induction melting and electroslag remelting are used to melt the pure iron in a vacuum furnace, and the required alloy components are added until the components meet the requirements of the first step, and then the alloy solution is cast into steel ingots, The steel ingot is rolled or forged to make a metal rod as a consumable electrode. The resistance heat generated by the slag when the current passes through the electroslag layer is used to gradually melt the consumable electrode. The molten metal falls through the slag layer to the In the molten metal pool in the wat...

Abstract

The invention relates to the technical field of the production process of a die casting die steel material, and specifically relates to a method for producing a long-fatigue life die casting die material. The method comprises the following steps: 1, selecting high-quality raw materials; 2, adopting the double refining of vacuum induction smelting and electroslag remelting; 3, six-side forging; 4, solution annealing; and 5, quality acceptance checking. The die casting material produced by the invention overcomes the disadvantage of the short thermal fatigue life of the traditional large hot die casting die, prolongs the service life of the die, and is mainly applicable to the die casting and extruding dies made of aluminum alloy, magnesium alloy and zinc alloy.

Description

technical field [0001] The invention relates to the technical field of production technology of die-casting mold steel materials, in particular to a production method of die-casting mold materials with long fatigue life. Background technique [0002] In die-casting production, thermal fatigue, cracking, and dents are common failure mechanisms of die-casting molds, and these reasons are often the result of the interaction of multiple factors. With the progress of the die-casting industry, the size of die-casting products is gradually developing into larger sizes, and the requirements for die-casting precision are getting higher and higher. How to improve the life of large-scale die-casting molds has become the focus of common attention in the current industry. [0003] From the early 1990s, the North American Die Casting Association promulgated the "Advanced H13 Acceptance Criteria)". Since then, high-grade H13 material has become the mainstream material in the die-casting i...
