Description

耐高温高强度承烧梁
技术领域
本发明涉及一种耐高温高强度承烧梁,属于无机非金属材料领域。
背景技术
目前国内汽车零部件结构行业中的加热电炉,普遍采用国外进口的硅酸铝质陶瓷制品,该制品分为一层或者多层,周边上下布置加热体,形成一定的加热空间,被加热器件由机器人抓取,受热后再取走。现有产品存在问题,重量大、蓄热多、导热慢、不节能、寿命短、价格高。
并且目前存在的产品因为重量大,因此本身就很难再体现高强度了,同时因为材质问题耐高温方面也很容易出现问题。
所以现在需要一种新型的耐高温高强度承烧梁,本发明构思由此而生。
发明内容
根据现有技术的不足,本发明要解决的技术问题是:提供一种耐高温高强度承烧梁,陶瓷承烧梁具有热稳定性优良,高温膨胀系数小;高温性能好强度大。
本发明解决其技术问题所采用的技术方案是:提供一种耐高温高强度承烧梁,由以下质量百分数的原料组成:
硼化钛:0.5%-5%
氮化硼:0.5-3%
金属硅:1%-10%
碳化硅:70%-80%
氮化硅:5%-20%。
所述的各个原料通过水混合均匀后,经过模具成型,然后在氮气保护下进行烧结,烧结温度为1650℃-1850℃,烧结时间为72-96小时。
一种耐高温高强度承烧梁,包括:前展部分和梁体主架,梁体主架上设置由凹槽,前展部分设置在凹槽内,其中梁体主架由三部分组成,两侧分别为边框架,中间为中心框架。
所述的前展部分、边框架和中心框架均为空心结构,壁厚大为5-12mm。
所述的前展部分、边框架和中心框架均为矩形结构或正方形结构。
所述的凹槽底部与中心框架顶部等高。
所述的前展部分的横截面为锥形结构。
所述的边框架的高度大于中心框架高度,边框架上设置凹槽的位置处,边框架内壁相应向内凹陷。以此来保证边框架的壁厚不会改变。
本发明的有益效果是:
1、陶瓷承烧梁具有热稳定性优良,高温膨胀系数小;高温性能好强度大,当温度1200℃的抗折强度是基本常温时的近两倍,这一特性是其它材料不及的。
2、导热性能好,高于其它的半导体材料;化学稳定性好,生产中应当避免混入杂质,以免造成性能降低;
3、承烧梁在900—1100℃保持刚性不变,确保安全使用。使用中表面可产生SiO2薄膜,利于保护产品不被氧化。
4、采用该发明,节能、质量轻、采购成本低,使用寿命长;
