Steel for pre-embedded fastener of glass curtain wall, and production method thereof

Abstract

The invention discloses steel for a pre-embedded fastener of a glass curtain wall, and a production method thereof. The steel for the pre-embedded fastener of the glass curtain wall comprises the following chemical components in percentage by mass: 0.06%-0.09% of C, not greater than 0.10% of Si, 0.30%-0.40% of Mn, 0.40%-0.45% of Cr, 0.40%-0.44% of Ni, 0.35%-0.40% of Mo, 0.20%-0.25% of Cu, 0.020%-0.050% of Al, 0.010%-0.030% of Ti, not greater than 0.018% of P, not greater than 0.010% of S, not greater than 0.0015% of [O], and the balance Fe, wherein As+Sn+Sb+Pb+Bi is not greater than 0.035%. According to the steel for the pre-embedded fastener of the glass curtain wall, and the production method thereof, low C content, Si content and Mn content are designed, and appropriate amounts of elements Cr, Ni, Mo, Cu, Ti, Al and the like are added in the steel, so that the toughness and the corrosion resistance of the steel are improved while the strength is guaranteed, and meanwhile, the weldability is improved. According to the production method, compared with a common Q355B steel plate, cutting procedures for the steel plate, and material waste are reduced, and therefore, the production method has the advantages of being efficient, economic, safe and the like, is capable of greatly overcoming the defects of a method for manufacturing a pre-embedded fastener from the Q355B steel plate,realizes efficient and energy-saving production, and improves the market competitiveness.

Description

technical field [0001] The invention relates to steel for building fasteners in the iron and steel industry, in particular to steel for pre-embedded fasteners for glass curtain walls and a production method thereof. Background technique [0002] Glass curtain wall is a new type of modern wall form, which was widely used in the design of public buildings after World War II. The glass curtain wall applies a large area of ​​glass to the exterior wall of the building to show the modern style of the building, give full play to the characteristics of the glass itself, and make the building look unique, thus giving people a new feeling. Compared with the traditional building enclosure structure, the glass curtain wall has the advantages of light weight, good light transmission, good sound insulation effect, heat insulation, moisture resistance, and high wind pressure resistance. At the same time, it also has single construction materials, convenient construction, and short construc...

AI Technical Summary

Problems solved by technology

The disadvantages of the glass curtain wall pre-embedded fasteners made of this steel are poor atmospheric corrosion resistance, poor toughness, and high production costs.
