粉煤灰酸法生产氧化铝溶出工序阀门的应用探讨

Process for producing alumina by fly ash acid method Application of valve

溶出是粉煤灰酸法提取氧化铝工艺中的关键工序,系统中使用的阀门必须具有耐高温酸性粉煤灰料浆腐蚀和抗冲刷的能力,因此要选用合适的阀门才能满足溶出工序的生产要求。

Dissolution is the key process in the process of extracting alumina fly ash acid method used in the system, the valve must have a high temperature resistant ability of fly ash slurry acid corrosion and erosion resistance, so the valve should be selected to meet the requirements of production process of dissolution.
