Embodiment 1

[0048] The E2 vertical roll is produced by the above process, and its specifications are: φ1360×720×2875mm. The specific forging process is as follows:

[0049] S11: Ingot heating, the heating temperature range is 1210-1230°C.

[0050] S12: out of the furnace, the whole ingot is upsetting H≤1200mm, and the FM method is drawn to 1200mm 2 , return to the furnace for homogenization, the homogenization temperature is 1220°C, and the time is 10h to obtain one upsetting and one drawing billet;

[0051] S12: out of the furnace, upsetting H≤1100mm, FM method drawing to 1400mm 2 , and then flatten the anvil and pull it to 1200mm 2 , return to the furnace for homogenization, the homogenization temperature is 1200 ° C, and the time is 2 to 4 h to obtain two upsetting and two drawing billets;

[0052] S13: out of the oven, upsetting H≤1100mm, FM method drawing to 1400mm 2 , and then flatten the anvil and pull it to 1200mm 2 , return to the furnace for homogenization, the homogenizatio...

Abstract

The invention discloses an E2 vertical roll forging process, which comprises the steps of: heating a steel ingot with a heating temperature range of 1210-1230° C.; upsetting the steel ingot as a whole, and upsetting to 1 / 3-1 / 2 of the height of the steel ingot, After upsetting, it is drawn for one time, and then returned to the furnace for homogenization; after being released from the furnace, it is upset again, and upsetting to 1 / 3 to 1 / 2 of the height of the billet for one upsetting and one drawing. After coming out of the furnace, upsetting for the third time, and upsetting to 1 / 3~1 / 2 of the height of the two upsetting and two drawing billets, and the third drawing after upsetting to obtain a billet with a height-diameter ratio ranging from 2.2 to 2.4, and then Homogenized by returning to furnace; spheronizing and stamping billet; die forging; post-forging heat treatment. Using this forging forming process, through the production method of three upsetting and three pulling, the breaking of the as-cast structure of the steel ingot can be fully guaranteed. Combined with the deformation amount and the effect of recovery and recrystallization, the grains can be fully refined, and then forged to produce, The prepared E2 vertical roll is of good quality and can meet the requirements of high-volume production and quality.

Description

technical field [0001] The invention relates to the technical field of forging, and more particularly, to a forging process for E2 vertical rolls. Background technique [0002] The E2 vertical rolling mill can roll the two vertical sides of the side-pressed slab in the hot-rolled strip mill to reduce and ensure the width and precision of the strip; the slab can be aligned with the rolling centerline, and the guide plate can be lifted. Slab effect; when rolling slabs with a thickness greater than 100mm, the iron oxide scale with a width of 300mm at the edge of the slab can be loosened, and then the descaling effect with high-pressure water is good. [0003] E2 vertical rolls usually have complex shapes and high product quality requirements. There shall be no defects such as cracks, pores, slag inclusions, blisters, and porosity that affect the use. The flaw detection requirements meet the requirements of level 3 of GB / T6402-2008 flaw detection method, and the rolling amount ...
