Abstract

The invention discloses a dedicated wear-resisting anticorrosion steel plate for a storage rack platform and a preparation method of the steel plate. The steel plate comprises the following components by mass percent: 0.28-0.31% of C, 0.45-0.47% of Mn, 0.09-0.12% of Si, 0.006-0.008% of P, S less than or equal to 0.004%, 0.07-0.09% of V, 0.08-0.12% of Ti, 0.10-0.13% of Al, N less than or equal to 0.006%, 0.012-0.015% of Cu, 0.4-0.6% of Cr, 0.33-0.36% of Mo, 0.015-0.032% of rare earth trace elements, and the balance of Fe and unavoidable impurities; the rare earth trace elements comprise the following chemical components in mass percent: 8-12% of Nd, 11-16% of Ce, 3-5% of Er, 2-6% of Pr, 1-4% of Pm, 0-5% of Dy, and the balance of La. The preparation method of the steel plate disclosed by the invention can be used for achieving a reasonable two-phase ratio, small ferrites and dispersed pearlites, avoids banded structures, and further improves the acid resistance due to lack of the banded structures.

Description

technical field [0001] The invention relates to a steel plate and a preparation method thereof, in particular to a special wear-resistant and anti-corrosion steel plate for a shelf platform and a preparation method thereof. Background technique [0002] The shelf platform is a steel platform built on the top of the heavy-duty shelf, and a steel structure that integrates the shelf and the platform. For the storage needs of special materials, the use conditions and environment of the shelf are becoming more and more harsh, and the thickness of the steel plate is getting thicker and thicker. Correspondingly, the technical requirements for steel plates used in storage equipment are also continuously increasing. Especially when it is used to store some corrosive goods, it often corrodes the column and loading steel plate of the shelf platform, causing the storage equipment to be damaged in a short time and increasing the storage cost. Therefore, how to effectively improve the we...
