The invention belongs to the field of forklift gantries, and particularly relates to F steel for a forklift gantry and a rolling technology. The F steel for a forklift gantry comprises a web; an inner flange is installed at the top of the web; a connecting cambered surface is arranged at the joint of one side of the inner flange and the web; a first outer flange is installed at the top of the web; a second outer flange is mounted at the top of the web and located on one side of the first outer flange; a boss is arranged at the joint of one side of the second outer flange and the web; and a transition arc surface is connected between the first outer flange and the second outer flange. According to the novel F-shaped steel for a forklift gantry obtained through the rolling technology, hot rolling forming is adopted, the rigidity of the gantry can be effectively improved through the designed outer web, meanwhile, the welding quality of gantry connecting pieces and various accessories is ensured, and the overall safety of the forklift gantry is improved.

    本发明属于叉车门架领域,尤其是一种叉车门架用“F”钢及轧制工艺,其中的叉车门架用“F”钢包括腹板,所述腹板的顶部安装有内翼缘,所述内翼缘的一侧与腹板的连接处设置为连接弧面,所述腹板的顶部安装有第一外翼缘,所述腹板的顶部安装有第二外翼缘,且所述第二外翼缘位于第一外翼缘的一侧,所述第二外翼缘的一侧与腹板的连接处设置为凸台,所述第一外翼缘和第二外翼缘之间连接有过渡圆弧面。本发明的轧制工艺的新型叉车门架用F型钢采用热轧成型,设计的外腹板可有效提高门架的刚度,同时确保了门架连接件及各种附件的焊接质量,提高叉车门架的整体安全性。
