Rolling mill guide alloy

Abstract

The invention discloses a rolling mill guide alloy, which comprises the following components: by weight percentage, 1.1-1.3% of C, 12-14% of Cr, 0.5-0.7% of Nb, 2.0-4.0% of W, 2.0-5.0% of Mo, 0.5-1.0% of V, 2.0-4.0% of Ti, 0.3-0.5% of Ce, 4.0-6.0% of Ni, 1.2-1.5% of Si, 1.8-2.2% of Mn and the balance Fe.

Description

technical field [0001] The invention relates to the field of metallurgical material processing, in particular to a rolling mill guide alloy. Background technique [0002] During the rolling process, the working environment of the guides (including the guide plates and guide rollers) at the steel import and export of the rolling mill is very harsh, and the red hot steel above 900°C passes through the guides continuously, and at the same time, it needs to be cooled by spraying water. , the temperature difference changes greatly and sharply. Therefore, the guide wears quickly, has a low service life, needs to be replaced frequently, consumes a lot, and is prone to cracks and breaks, which affects the production efficiency of steel rolling. In addition, the steel sticking phenomenon is easy to occur during the use of the guide and guard, which affects the quality of the rolled steel. The fundamental reason for sticking steel is that the guide and guard have a "welding effect" ...
