打渣剂中含有大量能增加铝、渣之间表面张力的物质，又含有一定数量的发热物质，使粘稠的湿渣、块状渣变成粉状渣，使渣中的铝很容易流回熔池，达到铝渣分离的目的。
打渣剂是一种专门用于将金属液与氧化物进行有效分离的混合物。它在金属冶炼和铸造过程中发挥着重要的作用，尤其在铅、锌等金属的铸锭和压铸过程中。
打渣剂的主要功能在于改变金属熔体与渣体之间的表面和界面张力，从而降低它们之间的结合力，使金属与渣能有效地分离。这不仅可以提高金属的利用率，还能减少渣对金属的污染，从而提高产品的质量。此外，打渣剂还能在金属熔体中产生气泡，起到搅拌作用，帮助将熔体中的渣翻动并牵引到表面，便于后续的除渣操作。
在使用打渣剂时，需要根据熔体的种类和量来确定适当的添加量。一般来说，打渣剂会被均匀地撒在熔体表面，或者通过特定的方式将其压入熔体中。在特定的反应时间后，熔渣会发生变化，如升温、变红或变成碎粉，此时即可进行扒渣操作。
The Dross Agent contains a lot of substances that can increase the surface tension between aluminum and slag, and contains a certain amount of heating substances, so that the viscous wet slag and block slag become powdery slag, so that the aluminium in the slag is easy to flow back to the melting pool, so as to achieve the purpose of aluminium slag separation.
Dross Agent is a mixture specifically designed to effectively separate metal liquids from oxides. It plays an important role in the metal smelting and casting process, especially in the ingot and die casting process of lead, zinc and other metals.
The main function of Dross Agent is to change the surface and interfacial tension between the metal melt and the slag body, so as to reduce the binding force between them, so that the metal and the slag can be effectively separated. This can not only improve the utilization rate of the metal, but also reduce the pollution of the slag to the metal, thus improving the quality of the product. In addition, the Dross Agent can also produce bubbles in the metal melt, play a stirring role, and help turn the slag in the melt and pull it to the surface, which is convenient for subsequent slag removal operations.
When using Dross Agent, it is necessary to determine the appropriate amount of addition according to the type and amount of melt. In general, the Dross Agent will be evenly spread on the surface of the melt, or it will be pressed into the melt in a specific way. After a specific reaction time, the slag will change, such as heating up, turning red or becoming crushed powder, at which time the slag scraping operation can be carried out.
