Description

一种矾土基β-Sialon碳滑板制备工艺
技术领域
本发明涉及一种制造受电弓碳滑板的工艺,特别是涉及一种矾土基β-Sialon碳滑板制备工艺。
背景技术
电力机车的动力连接器就是受电弓碳滑板,而碳滑板的重要材料即碳滑条。其工作原理就是碳滑条与接触电网摩擦接触取电,传送给电力机车,从而来维持其正常运行。由于工作环境是在自然环境中进行,有时会暴露冻雨、冰雪在恶劣的天气中,且还在高速运行,与接触电网不断产生摩擦,在摩擦的过程会有电弧、冲击等现象的发生,因而也成为频繁更换的部件。
由此可见碳滑条材料综合性能是其必备条件,其中高强度、高韧性、低电阻、耐磨以及自润滑特性的滑动电接触材料是最佳选择。
现如今电力机车受电弓碳滑板分为三种:粉末冶金滑板、纯碳滑板、碳基复合材料滑板。而且要保证碳滑板的导电性和自润性一般都会采取浸金属工艺,但是目前的碳滑板浸金属工艺较为复杂,而且效率偏低。
因此,申请人提出一种矾土基β-Sialon碳滑板制备工艺,其制备的碳滑板各项性能指标满足国标要求,且工艺简单、效率高。
发明内容
基于现有技术的不足,本发明提供了一种矾土基β-Sialon碳滑板制备工艺。
具体为,本发明提供的一种矾土基β-Sialon碳滑板制备工艺,包括如下步骤:

所述铜粉的平均粒度90-130目,密度为8.92×103/cm3;
所述改质煤沥青的软化点为90-100℃,结焦值为≥55%,灰分≤0.20%;
S2、混粉,将鳞片状石墨粉、碳化硼、α-氧化铝微粉、矾土基β-Sialon粉、铜粉按50-60:2-3:2-3:10-15:20-25的重量份数比均匀混合均匀,获得细粉,然后将板状刚玉颗粒与细粉按照重量份数比为30-40:60-65混合均匀。在混合过程中可以加入适量乙醇,从而增加混合的均匀度,混合完成后烘干;
S3、将S2中混合的原料与改质煤沥青按照重量份数比为10-20:0.4-0.5混合混匀,放入搅拌机中搅拌10-20分钟,出料备用;
S4、将S3中混合好的原料放入模型中,通过600吨以上的模压机压制成型,获得砖坯,砖坯的尺寸为30*30*200毫米;
S5、将S4中的砖坯放入焙烧炉中,升温方式如下:
室温-100℃,按照100℃/h升温,保持1h;
100-200℃,按照100℃/h升温,保持1h;
200℃-900℃、按照100℃/h升温,保持7h;
900℃-1200℃、按照按照150℃/h升温,保持2h;
然后自然冷却后,获得碳基体;
S6、将S5中的碳基体放入钢碳中,使钢碳完全包裹砖坯,然后冲入保护气(氩气),直到压力达到20兆帕,然后加热至800-1200摄氏度,保持24-30小时后取出;
S7、将S6处理后的砖坯进行加工,获得碳滑板。

S3、将S2中混合的原料与改质煤沥青按照重量份数比为20:0.5混合混匀,放入搅拌机中搅拌20分钟,出料备用;
S4、将S3中混合好的原料放入模型中,通过600吨以上的模压机压制成型,获得砖坯,砖坯的尺寸为30*30*200毫米;
S5、将S4中的砖坯放入焙烧炉中,升温方式如下:
室温-100℃,按照100℃/h升温,保持1h;
100-200℃,按照100℃/h升温,保持1h;
200℃-900℃、按照100℃/h升温,保持7h;
900℃-1200℃、按照按照150℃/h升温,保持2h;
然后自然冷却后,获得碳基体;
S6、将S5中的碳基体放入钢碳中,使钢碳完全包裹砖坯,然后冲入保护气,直到压力达到20兆帕,然后加热至1000摄氏度,保持30小时后取出;
S7、将S6处理后的砖坯进行加工,获得碳滑板。
