Analyzing on being right angle of space plane angles projection;
投影成直角的空间平面角再分析
The metal of the right angle isnt enough used of hot rolled equal and unequal angle steel Mean while,the right angle is easy producing stress concentration and difficult rolling Therefore,the section of angle steel was optimized,and a new section of round arc angle steel is put forward,which can be easily rolled,used and saved metal material over 5
热轧等边、不等边角钢直角处金属未被充分利用 ,易产生应力集中 ,且轧制难度大 ,因而对其断面进行了优化设计 ,提出一种新型圆弧角钢 ,其轧制容易 ,使用方便 ,可节约金属材料 5 %以
