一、前言邢台钢铁厂300m~3高炉工程,热风炉拱顶采用悬链线形拱顶,也叫霍戈文蘑菇曲线拱顶,其形状近似于一根有重量的定长柔索两端固定,在自身重量作用下,柔索所构成的悬链曲线。如果按霍戈文蘑菇曲线拱顶砌筑,需用十分复杂的砖形,给耐火制品制作和砌筑带来困难。如何简化砖形,使砌筑的拱顶又能近似悬链线型,一般采用多段圆弧线形代 First, the foreword Xingtai Iron and Steel Plant 300m ~ 3 blast furnace project, hot air stove vault using catenary vault, also known as Gordon mushroom curve vault, its shape is similar to a fixed length of soft wire ends fixed, Under its own weight, the soft cords constitute the catenary curve. If you press the Gordon mushroom curve of the vault masonry, the need to use a very complicated brick, refractory products to create and masonry difficulties. How to simplify the brick, so that the masonry can approximate the catenary vault line, the general multi-segment arc generation on behalf of
