Impact-resisting high-strength alloy material for partition wall of bearing warehouse and processing technique of alloy material

Abstract

The invention discloses an impact-resisting high-strength alloy material for a partition wall of a bearing warehouse. The alloy material comprises the following components in percentage by mass: 0.31-0.43 percent of C, 0.29-0.35 percent of Mn, 0.11-0.13 percent of Si, 0.15-0.21 percent of Nb, 0.01-0.03 percent of W, 0.18-0.36 percent of V, 0.54-0.56 percent of Ti, 0.031-0.043 percent of Y, 2.17-3.19 percent of Al, 0.08-0.12 percent of Cu, 0.28-0.32 percent of Ni, 0.18-0.22 percent of Nb, 0.85-0.95 percent of Cr, 0.17-0.25 percent of Mo, 0.25-0.32 percent of rare-earth trace elements and the balance of Fe and unavoidable impurities, wherein the total content of the impurities is smaller than or equal to 0.2%; the content of P is smaller than or equal to 0.004%; the content of S is smaller than or equal to 0.006%; the content of H is smaller than or equal to 0.004%; the content of N is smaller than or equal to 0.006%; the content of O is smaller than or equal to 35ppm; the mass percentage of chemical components of the rear-earth trace elements is as follows: 2-4 percent of Nd, 4-8 percent of Ce, 2-6 percent of Pr, 1-4 percent of Pm, 0-5 percent of Dy and the balance of La. The invention also discloses a processing technique of the impact-resisting high-strength alloy material for the partition wall of the bearing warehouse. The alloy material disclosed by the invention is high in strength, high in toughness, excellent in processability, resistant to high temperature, resistant to corrosion, unlikely to abrade and long in service life.

Description

technical field [0001] The invention belongs to the field of metal material processing, and relates to an alloy material for an impact-resistant high-strength load-bearing storage partition and a treatment process thereof. Background technique [0002] Storage equipment refers to the technical devices and tools that can meet the needs of storage and storage of goods. Storage equipment is the main symbol of the level of storage and logistics technology. Modern storage equipment reflects the development of modern storage and logistics technology. The shelf in the storage equipment is a relatively commonly used equipment. The shuttle car shelf is characterized by the fact that the forklift does not need to enter the roadway, which saves time, improves the safety of personnel and goods, and greatly improves the storage and retrieval efficiency of goods in the warehouse.

Problems solved by technology

The shelf in the storage equipment is a relatively commonly used equipment. The shuttle car shelf is characterized by the fact that the forklift does not need to enter the roadway, which saves time, improves the safety of personnel and goods, and greatly improves the storage and retrieval efficiency of goods in the warehouse. Make full use of the warehouse space. About 80% to 85% of the space can be used, which is suitable for different types of products and can be accessed flexibly in layers. Compared with the drive-in frame and the through frame, the structure is stable and the safety factor is high. It can realize first-in-first-out and first-in-last-out; The storage requirements of special materials, the use conditions and environment of shuttle car shelves are becoming more and more harsh, and the thickness requirements for steel plates are getting thicker and thicker. Transverse yield strength; in addition, especially when used to store some corrosive goods, the storage equipment often breaks in a short time due to the corrosion of the steel plate, which increases the storage cost; and in some cold regions, the shelf load-bearing The low-temperature toughness of the steel plate is not high, which often causes the storage equipment to break in a short time
