四辊干平整机在轧制时,由于带钢和轧辊直接接触,在轧制压力下,干摩擦产生轧制粉尘,这些粉尘主要产生在辊缝区域,会随着带钢运行造成的气流,被带入辊缝,造成表面的缺陷。本技术通过引入流体场的模拟,根据粉尘特性、机架布置、气流、除尘口特性等要素模拟出靠近干平整机辊缝区域的气流特性,总结和设计出一套高速在线干平整机的辊缝除尘设备,将轧制粉尘有效地去除。
Four-roll dry-leveler During rolling, due to the direct contact of the strip with the roll, dry friction creates rolling dust under the rolling pressure, which mainly occurs in the area of the roll gap and will flow as the strip runs , Was brought into the nip, causing surface defects. According to the simulation of fluid field and the simulation of the airflow characteristics near the area of the roll gap of the dry-setting machine according to the characteristics of dust, rack arrangement, air flow and dust-removal opening, this technology summarizes and designs a set of high-speed on-line dry- The roll gap dust removal equipment will effectively remove the rolling dust.
