用不同糙度表面的轧辊轧制板材的工艺研究和应用,是在轧辊直径为900毫米的2500可逆式二辊轧机上进行的。在轧机上把厚200～300毫米的铸锭(铸坯)轧制成厚8～15毫米的铝合金(AM_r2、AM_r5、Д1、Д16等)板材。轧制前将金属加热到380～500℃。根据工艺规程,下轧辊直径比上轧辊大2～15毫米。轧辊的表面糙度相同,R_α≈0.75～0.95微米。 The research and application of the process of rolling plates with rolls with different roughness surfaces was carried out on a 2500 reversible two-roll mill with a roll diameter of 900 mm. In the rolling mill on the thickness of 200 ~ 300 mm ingot (slab) rolling 8 ~ 15 mm thick aluminum alloy (AM_r2, AM_r5, Д1, Д16, etc.) plate. Before rolling the metal is heated to 380 ~ 500 ℃. According to the procedure, the diameter of the lower roll is 2 ~ 15mm larger than that of the upper roll. Roll surface roughness, R_α ≈ 0.75 ~ 0.95 microns.
