The invention discloses an E2 vertical roller
forging forming technology. The E2 vertical roller
forging forming technology comprises the steps that steel
ingot heating is conducted, and the
heating temperature range is 1,210 DEG C-1,230 DEG C; integral steel
ingot upsetting is conducted, a steel
ingot is subjected to upsetting to 1 / 3-1 / 2 of the height of the steel ingot, and after upsetting, first-time drawing is conducted, and then, the steel ingot returns to a furnace for homogenizing; after furnace discharging, upsetting is conducted again, upsetting is conducted to 1 / 3-1 / 2 of the heightof a first-upsetting and first-drawing blank, and after upsetting, drawing is conducted again, and then, the steel ingot returns to the furnace for homogenizing; after furnace discharging, third-timeupsetting is conducted, upsetting is conducted to 1 / 3-1 / 2 of the height of a second-upsetting and second-drawing blank, and after upsetting, third-time drawing is conducted, a blank with the height-
diameter ratio being 2.2-2.4 is obtained, and then the blank returns to the furnace for homogenizing;
rounding embossing blank manufacturing is conducted; die
forging forming is conducted; and heat treatment after forging is conducted. By adoption of the forging forming technology, the three-upsetting and three-drawing production manner is adopted, crushing of a steel ingot cast-
state structure canbe sufficiently guaranteed, and in combination with deformation and reversion and recrystallization effects, grains are sufficiently refined; and through forging production, the quality of a preparedE2 vertical roller is good, and volume production and quality requirements can be met.
