Description

一种泵体砂型铸造用铸造砂
技术领域
本发明涉及一种泵体砂型铸造用铸造砂，应用于泵体铸造技术领域。
背景技术
制造砂型的基本原材料是铸造砂和型砂粘结剂。硅砂的高温性能不能满足使用要求时则使用锆英 砂、铬铁矿砂、刚玉砂等特种砂。但相对硅砂来说，这些特种砂的价格稍高，增加了生产成本，不适合小规模铸造厂。为此，我们设计一种泵体砂型铸造用铸造砂。
发明内容
为解决现有技术方案的缺陷，本发明公开了一种泵体砂型铸造用铸造砂。
本发明公开了一种泵体砂型铸造用铸造砂，其铸造工艺具体步骤如下：
1）按照重量组份称取环氧树脂50-60份、酚醛树脂30-40份、丁苯橡胶12-15份、石灰水200-220份，投入剪切设备中，在转速1500-2000转/分钟的转速下，处理1-2h，备用；
2）按照重量组份称取石英砂70-80份，膨润土5-7份，煤粉3-4份，灰骨粉4-6份，铝矾土1-3份，氯化钙1-3份、硬脂酸镁5-8份、 果胶4-6份、石墨粉3-5份，经研磨机研磨粉碎，过900-1000目筛，获得粉末状混合料；
3）将获得的粉末状混合料投入1）中剪切设备中，设备内温度升温至70-80℃，在转速2500-300转/分钟的转速下，处理2-3h，再缓慢冷却至室温；
4）将3）中的混合粒料液投入造颗粒机中，制得50-100目筛的铸造砂；
5）制备内模，使用高温陶瓷烧制内模，内模做成中空结构，中空部分灌入甘油冷却液，将内模作芯，使用4）配制的铸造砂制作外模；
6）将铁水溶液倒入铁水包中，利用铁水包把铁水溶液从外模的冒口处浇注砂箱内，获得泵体胚体，待风冷却成型。
本发明的有益效果是：本发明以石英砂为主要原料，辅以多种功能助料制得泵体砂型铸造用铸造砂，该铸造砂具有优异的耐火度和热稳定性，不会与金属液发生化学反应，并且成型性、透气性和抗液态金属渗透性好，能减少浇注过程中的发气量，从而防止泵体出现砂眼、气孔、碳渣等缺陷，提高泵体质量，同时可以减少泵体落砂和清理劳动量，节省铸造时间。
具体实施方式
本发明公开了一种泵体砂型铸造用铸造砂，其铸造工艺具体步骤如下：
1）按照重量组份称取环氧树脂50-60份、酚醛树脂30-40份、丁苯橡胶12-15份、石灰水200-220份，投入剪切设备中，在转速1500-2000转/分钟的转速下，处理1-2h，备用；
2）按照重量组份称取石英砂70-80份，膨润土5-7份，煤粉3-4份，灰骨粉4-6份，铝矾土1-3份，氯化钙1-3份、硬脂酸镁5-8份、 果胶4-6份、石墨粉3-5份，经研磨机研磨粉碎，过900-1000目筛，获得粉末状混合料；
3）将获得的粉末状混合料投入1）中剪切设备中，设备内温度升温至70-80℃，在转速2500-300转/分钟的转速下，处理2-3h，再缓慢冷却至室温；
4）将3）中的混合粒料液投入造颗粒机中，制得50-100目筛的铸造砂；
5）制备内模，使用高温陶瓷烧制内模，内模做成中空结构，中空部分灌入甘油冷却液，将内模作芯，使用4）配制的铸造砂制作外模；
6）将铁水溶液倒入铁水包中，利用铁水包把铁水溶液从外模的冒口处浇注砂箱内，获得泵体胚体，待风冷却成型。
最后应说明的是：以上实施例仅用以说明本发明而并非限制本发明所描述的技术方案；因此，尽管本说明书参照上述的各个实施例对本发明已进行了详细的说明，但是，本领域的普通技术人员应当理解，仍然可以对本发明进行修改或等同替换；而一切不脱离本发明的精神和范围的技术方案及其改进，其均应涵盖在本发明的权利要求范围中。
