　　【化工仪器网政策标准】如今，我国购买高温激光共聚焦显微镜设备的用户已有很多家，渣类材料熔化温度测试技术也达到各厂家及用户间相互比较、交流的地步，但目前还没有利用高温激光共聚焦显微镜测定渣类材料熔化温度的方法标准，因此根据相关标准制定适合我国国情的国内检测标准是必要和及时的。

　　近期，由全国钢标准化技术委员会归口上报，全国钢标准化技术委员会金相检验分会执行，中国钢铁工业协会主管，首钢总公司、冶金工业信息标准研究院遵循“面向市场、服务产业、自主制定、适时推出、及时修订、不断完善”的原则，主要起草的已经编制完成，正面向社会征求意见。

　　本着先进性、科学性、合理性和可操作性以及标准的目标、统一性、协调性、适用性、一致性和规范性原则，起草组在编制《渣类材料熔化温度的测定高温激光共聚焦显微镜法》的过程中，主要按GB/T1.1-2009《标准化工作导则第1部分：标准的结构和编写规章》的要求进行编写，并引用了YB/T 186《连铸保护渣熔化温度试验方法》和GB/T 1425《贵金属及其合金熔化温度范围的测定热分析试验方法》。

　　阅读《渣类材料熔化温度的测定高温激光共聚焦显微镜法》征求意见稿后可知，标准规定了渣类材料熔化温度测定的方法原理、仪器与制样设备、试样制备、实验步骤、结果表征和试验报告，适用于冶炼炉渣和连铸保护渣，成分类似的矿石等熔化温度的测定也可参照使用。

　　本标准所使用的方法原理是显微镜配有高温炉，把制备好的柱状试样放高温炉内氧化铝坩埚中的铂金垫片上，按设定的升温速率加热到试样熔化流动，随后按设定的冷却速率降温到室温。利用显微镜进行原位观察和拍照或录制实验过程视频，记录熔化温度即可。故而实验中需要的仪器设备包括有高温激光共聚焦显微镜、坩埚和铂金垫片、成型模具。

　　目前国内关于熔化温度检验标准有《连铸保护渣熔化温度试验方法》和《贵金属及其合金熔化温度范围的测定热分析试验方法》，相信通过本标准的制定和实施，不仅能丰富对于熔化温度测定的标准，还能有效促进技术创新，增强产品的国内外市场竞争力，同时对规范市场竞争，引导市场良性发展，加快我国渣类材料测试技术快速发展也将有着积极的促进作用。
