辐射形耐火砌砖(楔形砖与直形砖配砌的混合砌砖,两种楔形砖配砌的双楔形砖砌砖)的计算,一向是耐火材料专业工作者关心的问题。日本《耐火物手帐》一书讨论了它,苏联《耐火材料生产》的上册及下册分别开辟了一章专门论述这个问题。笔者在我国1981年第4期《耐火材料》上发表的《辐射形耐火砌砖新计算方法的研究》一文中说:“国外耐火材料专业书籍中,辐射形耐火砌砖的计算式相当复杂,并且不够完善,都以一定的条件为前提:或‘等大头尺寸’,或‘等 Radiation-shaped refractory bricks (wedges and straight bricks with mixed brick laying, two wedge-shaped bricks with double-wedged brick wedges) has always been the concern of refractories professionals. Japan “Refractory Account” a book to discuss it, the Soviet Union, “refractory production,” the first and second volumes have opened up a chapter devoted to this issue. The author in our country in 1981, No. 4 “Refractory” published “radiation-shaped refractory bricks new calculation method,” one article said: "foreign refractories professional books, radiant refractory bricks formula is quite complex, And not perfect, are based on the premise of certain conditions: or ’such big size’, or ’wait
