Problems solved by technology

However, stainless steel itself has high strength and plastic deformation ability, poor processing performance, and the process of making expanded metal mesh is complicated; at the same time, the cost of stainless steel material itself is very high, about 4 times that of galvanized steel, so the application of stainless steel expanded mesh is restricted. Great restrictions, only in the field of special requirements, such as tableware, cooking utensils, etc.

Abstract

The invention discloses an aluminized steel sheet mesh. The aluminized steel sheet mesh comprises a steel sheet mesh, wherein from inside to outside, the steel sheet mesh includes a substrate layer, an iron-aluminum alloy layer and an aluminum layer, and preferably the iron-aluminum alloy layer is 14-29 microns in thickness. A method for preparing the aluminized steel sheet mesh comprises the following steps of I, shaping a steel coil, a steel sheet or a steel strip into a steel sheet mesh work piece through punching and drawing; II, baking to remove oil; III, acid-pickling to remove rust; IV, washing; V, surface-activating; VI, permeation-promoting; VII, drying; VIII, implementing rapid inductive aluminizing; immediately immersing the dried work piece in molten aluminum which is heated to 680-700 DEG C by an inductive way for 2-3 minutes, thus obtaining a steel sheet mesh with surface aluminized. The preparation method can be used for not only guaranteeing the mechanical performance of the steel sheet mesh, but also ensuring excellent corrosion resistance and long service life; the preparation method can be used for greatly reducing the maintenance cost of the steel sheet mesh in later period.

Description

technical field [0001] The invention relates to the field of expanded metal mesh, in particular to an aluminized expanded metal mesh and its preparation method, which is suitable for mesh-shaped tension fences and fences in the field of construction, as well as escalators and walkways for mechanical equipment, and is mainly used as mechanical equipment, highways, stadiums, It can also be used as a protective fence in airports, etc., and can also be used as escalators and walkways for oil tankers, heavy machinery, boilers, ships, etc. Background technique [0002] Expanded metal mesh is a mesh-shaped material object formed by stamping and stretching a steel plate or steel coil or steel strip through an expanded metal punching and shearing machine. Due to its advantages of material saving, firmness, and long life, it is widely used in mechanical equipment, high-speed Fences and guardrails for highways, stadiums, airports, etc., can also be used as escalators and walkways for o...
