The ZINCALUMER coating process is a core business of BlueScope Steel. Operational and quality issues are being experienced due to inter-metallic particles in the liquid metal bath. The particles cause defects in the metal coating and agglomerate, resulting in periodic shutdowns to remove the dross. Both of these factors impact significantly on the profitability of the operation. In this project a new strategy is being investigated, whereby the fluid mechanics and heat transfer mechanisms within the bath will allow inter-metallic particles to be continuously removed in the metal coating before they reach the critical size that adversely affects product quality. This will also reduce dross accumulation, thereby reducing shutdown time.

ZINCALUMER涂装工艺是BlueScope Steel的核心业务。由于液态金属槽中的金属间颗粒，正在经历操作和质量问题。这些颗粒会导致金属涂层中的缺陷和结块，导致定期停机以清除污垢。这两个因素都对业务的盈利能力产生了重大影响。在这个项目中，正在研究一种新的策略，根据该策略，熔池内的流体力学和热传递机制将使金属涂层中的金属间化合物颗粒在达到对产品质量产生不利影响的临界尺寸之前被连续去除。这还将减少渣土堆积，从而减少停机时间。
