| Abstract | 硫酸改性低品位凹凸棒石显著提高凹凸棒石的含量,然而会造成凹凸棒石中的硫含量大幅提高。而电焊条对药皮中硫含量要求很严格,硫含量高时焊缝容易产生裂纹。为了降低低品位凹凸棒石中的硫含量,本文研究了酸改性低品位凹凸棒石的碱处理工艺,并经过配方研制,成功将低品位凹凸棒石添加到E4303电焊条药皮中,降低了电焊条的生产成本,获得了性能较好的电焊条。 |
| Other Abstract | It could significantly improve the attapulgite content of low-grade palygorskite modified by sulfuric acid, however would lead to higher sulfur content of palygorskite noteworthly. The electrode is very strict with sulfur content in the coating, and high sulfur content in electrode welding would crack easily. In order to reduce the sulfur content in the sulfuric acid modified low-grade palygorskite, this paper studies the alkali treatment process of sulfuric acid modified palygorskite. Then, tow-grade palygorskite is added to the E4303 electrode coated successfully after formulation. It would obtain a good welding electrode performance and reduce the cost of production of welding electrode. |
