Embodiment 1
[0040] The present invention also provides a method for manufacturing an extrusion die using a self-lubricating extrusion die material for aluminum profile processing, specifically implemented according to the following steps:
[0041] Step 1, weigh the following components according to mass percentage: C 4.0%, Si 2.2%, Mn 1.3%, Ni 2.0%, Cu 1.5%, Mg0.03%, P0.03%, S0.03%, the balance is Fe, the sum of the mass percentages of the above components is 100%;
[0042] Step 2, smelting the material weighed in step 1 in a high-temperature melting furnace with a temperature of 1520°C until it is completely melted to obtain mixed molten iron;
[0043] Step 3, pouring the mixed molten iron obtained in step 2 into the preheated continuous casting machine matching holding furnace through the transfer ladle for heat preservation, adding ferrosilicon nodulizer and rare earth inoculant for spheroidization and inoculation, to obtain the production of molten iron;
[0044] Among them, the prehea...
