High-strength antiseptic steel plate for shuttle car shelf and machining process thereof

Abstract

The invention discloses a high-strength antiseptic steel plate for a shuttle car shelf. The steel plate comprises the following components: 0.77-0.79% of C, 0.17-0.19% of Mn, 0.14-0.16% of Si, 0.006-0.008% of P, 0.002-0.004% of S, 0.083-0.085% of Nb, 0.03-0.05% of V, 0.86-0.89% of Ti, 0.53-0.57% of Al, N not more than 0.006%, H not more than 0.00020%, 0.17-0.19% of Cu, 4.7-4.9% of Cr, 0.13-0.15% of Mo, 0.11-0.013% of lanthanum, 0.06-0.08% of cerium, 0.02-0.04% of praseodymium, and the balance of Fe. The steel plate is strong in corrosion resistance, high in transverse yield strength and excellent in low-temperature toughness.

Description

technical field [0001] The invention relates to a steel plate and a preparation method thereof, in particular to a high-strength anti-corrosion steel plate used for shuttle car shelves and a processing technology 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%~85% of the space can be used, which is suitable for different types of products and can be layered and flexibly accessed. 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; due to special The storage requirements of materials, the use conditions and environment of shuttle car shelves are becoming more and more harsh, and the requirements for the thickness of steel plates are getting thicker and thicker. 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 steel plate on the shelf The low-temperature toughness is not high, and it often causes the storage equipment to break in a short time
