1963年以来,針对我厂鍛压能力不足,我們在500軋机上对模具鋼3Cr2W8V采用了以軋代鍛开坯的新工艺試驗工作。經过四次試驗,初步获得了一些結果。試驗用鋼錠重为280公斤的鎮靜鋼,其保温帽尺寸为238~245毫米,小头尺寸为185毫米。軋制規格为110毫米方坯。加热炉为双排三段連續式燃煤加热炉,炉底有效面积为64.6米~2,有效炉长为18米。500軋鋼机为三輥横列式两架,主馬达能力为1500瓩,軋輥轉数为110轉/分,最大軋輥外徑为540毫米,最小軋輥外徑为480毫米。現将3Cr2W8V
Since 1963, for our lack of forging capacity, we used in the 500 mill on the mold steel 3Cr2W8V rolled forging billet new technology test work. After four experiments, some preliminary results have been obtained. Test steel ingot weight 280 kg of killed steel, the insulation cap size 238 ~ 245 mm, a small head size of 185 mm. Rolling specifications for the 110 mm billet. Heating furnace for the double row three sections of continuous coal-fired furnace, bottom effective area of 64.6 m ~ 2, effective furnace length of 18 meters. 500 rolling mill for the three-roller two-row type, the main motor capacity of 1500 瓩, the number of roll rotation 110 rev / min, the outer diameter of the largest roll 540 mm, the smallest roll outer diameter of 480 mm. Now 3Cr2W8V
