The invention discloses a novel ultrahigh-temperature die-casting process for stainless steel. The novel ultrahigh-temperature die-casting process comprises the following steps of die selection, material pressing barrel selection, molten steel casting, molten steel water injection, fluidity adjustment and automatic cover closing. According to the novel stainless steel die-casting process, preparation production can be completed only through one procedure of manufacturing the shell in a normal-temperature operating environment, and the problems of multiple procedures, low efficiency, high cost and the like caused by five procedures of a paraffin loss method precision casting process are solved; no waste water is generated in the production process, only a very small amount of waste gas is generated in a very short time of several seconds during die casting, the problems that a large amount of toxic waste water and waste gas are generated for a long time and the environment is seriously polluted in the paraffin-losing method precision casting process are solved, and the paraffin-losing method precision casting method has the advantages of high efficiency, energy conservation, environmental protection and low cost; and the method is a brand-new stainless steel structural part forming process technology with high popularization value.
Description
technical field [0001] The application relates to the technical field of ultra-high temperature die-casting application of stainless steel, in particular to a new ultra-high temperature die-casting process for stainless steel. Background technique [0002] Although the general metal die-casting molding process is very common now, in the industry, only brass, magnesium, aluminum, zinc and other medium and low melting point alloys can be die-casted, and stainless steel materials cannot be die-casted. The melting point of the above-mentioned die-casting materials is the highest. The most important is brass, the die-casting temperature is 960 degrees Celsius, which is already recognized as a high-temperature die-casting in the existing die-casting process, while the die-casting temperature of stainless steel is as high as 1650 degrees Celsius, which is 172% of the existing highest (brass) die-casting temperature. The scope of high-temperature die-casting, so in the die-casting i...
