各种工业炉窑的顶拱,常设计成倾斜的(对水平成某角度)。斜顶的砌砖方法已知有两种:(1)砖环斜砌,如图1所示。这种砌法的优点是顶的内面(工作面)光滑,有利于高温时的热辐射。但最严重的缺点是平顶与斜顶接头处(图1中 A,B)的耐火砖须加工,特别是 A 处的砖需加工成下大上小的形状。我们都知道,加工耐火砖非常费时,而且加工后的砖质量降低,用其砌好的顶拱也不坚固;而且工业炉炉顶的跨度很大,或多或少地要使用直砖与楔形砖配合,例如团矿炉加热带的炉顶就是这祥砌。因此接头处 A 常因掉砖而早期损坏。(2)砖环垂直砌,如图2所示,利用工作面“错台”的方面满足设计所要求的斜度。这种砌法唯
The top arch of a variety of industrial kilns, often designed to tilt (at an angle to the level). There are two known methods of slash-top brick-laying: (1) brick ring slanting, as shown in Fig.1. The advantage of this method is that the top inner surface (working surface) is smooth and conducive to heat radiation at high temperatures. However, the most serious disadvantage is that the refractory bricks at the flat-top and inclined-roof joints (A, B in Fig. 1) are to be worked, and in particular, the bricks at A are to be machined into the shape of the lower part and the lower part. We all know that processing refractory bricks is very time-consuming, and the quality of bricks after processing is reduced, and the roofing arch with it is also not strong. Moreover, the roof of industrial furnaces has a large span, more or less straight bricks and wedges Bricks with, such as the furnace top of the furnace furnace is this Cheung puzzle. Therefore, the joint A often due to broken brick and early damage. (2) vertical brick masonry ring, shown in Figure 2, the use of face “wrong Taiwan” to meet the design requirements of the slope. This kind of puzzle only
