The utility model relates to a new type of kiln, which comprises a kiln body and has a kiln wall inside the kiln body. The upper end of the kiln wall is formed with a placing end face, and a number of beams arranged in sequence are arranged on the placing end face. A hanging and firing gap is formed between the beams, and the sags on both sides of the beams make the cross section of the beams present a \I\ shape. Roller bars are inserted inside the hanging gap, and through holes are arranged at the top of the rollers. The through holes are embedded with hanging bars. The two sides of the hanging bars extend to the outside of the through holes, and the two sides of the hanging bars are placed at the top of the beam body. Compared with the original technical scheme, the contact area of the beam body and the kiln wall of the utility model keeps unchanged, and the stability is good; the beam body only contacts air on the outer surface, and the overall surface area is reduced by 30% compared with the traditional beam body, which gradually oxidizes from the surface to the inside, and has good oxidation resistance; the thermal shock resistance is strong, the service life of the traditional kiln beam body is long, and the service life of the traditional kiln beam body is about 50 times. The beam body of the new kiln has been used 150 times and its service life has been increased more than twice.
【技术实现步骤摘要】
一种新型窑炉
本技术涉及一种窑炉,特别涉及高温氧化铝行业用的烧制窑炉。
技术介绍
目前,高温氧化铝行业中的辊棒,在辊道窑炉中起承载和传送烧成产品的作用。而碳化硅方梁则是高温氧化铝行业中所必须的耐高温支撑窑具,由于窑炉在使用中的开炉温度高,内外环境温差大,矩形梁受热冲击大,传统空心结构的矩形梁窑炉,使用中存在以下问题:梁的端部容易炸裂,出现掉碴现象,内部梁的内外表面同时氧化并且逐渐向“芯”部扩展,抗氧化能力差,使用寿命短,开炉门温度受限。
技术实现思路
本技术目的在于提供一种新型窑炉,在以往矩形梁结构的基础上进行改进,新设计的窑炉克服了上述炸裂、掉碴问题,经验证使用寿命提高两倍以上。本技术解决上述技术问题的技术方案如下:一种新型窑炉,所述窑炉包括炉体,炉体内部设有窑墙,所述窑墙上端形成有放置端面,所述放置端面上设有若干依次排列的梁体,所述梁体之间形成有吊烧间隙,梁体的两侧凹陷使梁体的截面呈现为“工”字型。作为新型窑炉的优选方案,所述窑墙呈“口”字型设置在炉体的内侧,所述窑墙内侧形成有容纳空间,放置端面呈水平状。水平状的放置端面确保梁体与之形成良好的接触,确保了梁体的平稳性。 ...
