本发明公开了一种铁矿烧结粘结相粘结强度测定方法，包括如下步骤：试验试样制备：将第一基片尾端搭在第二基片的首端上；在搭接面上设有粘结相团块，粘结相团块加热融化后将第一基片和第二基片平行搭接粘结，制得试验试样；剪切力实验：利用夹具竖直夹持试验试样中第二基片的尾端，在第一基片的首端施加竖直方向的压力，进行剪切力实验，测得第一基片和第二基片搭接处破坏时的剪切力最大载荷F，用以计算粘结相粘结强度R。该方法具有适用范围广、实验条件可控、操作简单快捷、与实际烧结过程相符等优点。

The invention discloses a method for measuring the bonding strength of iron ore sintering bonding phase, which comprises the following steps: preparation of test sample: lapping the tail end of the first substrate on the head end of the second substrate; A bonding phase mass is arranged on the overlapping surface, and after the bonding phase mass is heated and melted, the first substrate and the second substrate are overlapped and bonded in parallel to prepare the test sample; Shear force experiment: use the clamp to vertically clamp the tail end of the second substrate in the test sample, apply a vertical pressure on the head end of the first substrate, conduct the shear force experiment, and measure the maximum shear force load F when the lap joint of the first substrate and the second substrate is damaged, so as to calculate the bonding strength R of the bonding phase. This method has the advantages of wide application range, controllable experimental conditions, simple and fast operation, and is consistent with the actual sintering process.
