Description
Technical field
The invention belongs to building material technical field, it is related to a kind of island building special steel alloy.
Background technology
With the sustainable development of marine economy, under the development space restriction of coastal area gradually saturation, Islands Exploitation band
A brand-new development space is carried out.Island is also more highlighted as the second marine economy band, its effect.
Steel structure technique the advantage of island utilization and extention be mainly reflected in it is following some：1, structure is light, transport and
It is easy for installation, and steel itself excellent toughness and ductility, possess good antidetonation and wind loading rating.Due to from heavy and light, because
This building is less demanding to the based process of ground, so as to greatly reduce the cost of ground transformation.The advantage is for natural calamity
Evil takes place frequently, and the island region of communications and transportation inconvenience can then give full play to its superiority.2, the superior performance of steel construction can be
Residence space provides more flexible in the bigger free degree, design, so as to be effectively increased the usable floor area of house.Therefore, efficiently
Percentage of usable dwelling area be more suitable for the island that land area is nervous, physical features is complicated.3, processing, construction and the installation of steel member are to environment
Influence is small, and steel recoverable, building waste greatly reduces.Therefore, in construction to building waste processing procedure
The destruction to periphery ecological environment is effectively reduced, effective technology can be provided to build green, environmental protection, energy-conservation and environmental island
Ensure.
However, the material development of China's steel building, manufacture and design can not meet Islands Exploitation utilize during it is right
The specific demand of Building technology.This is due to that under the conditions of marine climate, weather is moist throughout the year, and mean annual precipitation compares continent
Property weather is more；And season distribution ratio is more uniform.Precipitation is more stable, changes little between Nian Yunian.Four seasons humidity is all very
Greatly, many clouds and mists, It is gloomy, rare fine day, rare sunlight.Island building is in high temperature, high humidity, high salinity and high-strength ultraviolet
Natural environment in, although steel construction especially incomparable advantage, there is also its inevitable shortcoming, it is impossible to resistance to height
Wet, resistance to high salinity, often for a long time be in this environment in, can gradually suffer erosion, even people it is common or
It is that well known stainless steel can not also ensure not suffer erosion that person, which says,.Its service life is restricted.
The content of the invention
Goal of the invention：For weak point of the prior art, closed the invention provides a kind of island building special
Jin Gang.The service life of steel in rugged environment, can be extended.
Technical scheme：Build special steel alloy in a kind of island, it is characterised in that described island building special
Steel alloy is made up of alloy steel matrix and protective layer, described alloy steel matrix wherein using iron as main component, also containing carbon,
Niobium, nickel, copper, cerium, its each Ingredient percent is：Iron 88~92%, carbon 0.2~0.3%, niobium 0.3~0.8%, nickel 6~
7%th, copper 0.3~0.8%, cerium 0.1~0.2%；Described protective layer by protective agent coat after formed.We have found under study for action
Micro niobium is added in the steel of common iron-carbon formation, the corrosion resistance of steel can be strengthened.A small amount of nickel is added, can be carried
The ability of corrosion and the stress corrosion of high weak acid resistant.Furthermore it has been found that the resistance to sky of steel can be improved by adding micro copper
The performance of vapour corrosion in gas.Specifically, for the present invention, preferred scheme is：Build special alloy in the island
Each Ingredient percent of steel is：Contain iron 91.8%, carbon 0.2%, niobium 0.5%, nickel 7%, copper 0.3%, cerium 0.2%.
Further study, be both to be surface-treated again in the outer surface of the steel.Specifically, the present invention is also carried
The preparation method of the steel is supplied.For the present invention, according to above-mentioned formula, it is molded using conventional metallurgical method metallurgy.
After after steel shaping, being its outside coating protective agent, described protective agent coats one layer, that is, obtains island building special
Steel alloy.
Further, after coating protective agent, irradiated 20~30 minutes with ultraviolet, its effect is more preferable.
Specifically, described protective agent is the mixture of the metallic solution containing chromium.The described metallic solution containing chromium is chromium
Acyl chlorides and dichromic acid, the mixture of magnesium chromate.The proportioning of the described metallic solution containing chromium is 10 parts of chromyl chloride, dichromic acid 1~2
Part, 5~15 parts of magnesium chromate, 80~100 parts of water.It is preferred that 10 parts of chromyl chloride, 1 part of dichromic acid, 5 parts of magnesium chromate, 80 parts of water.
Beneficial effect：The resistance to moisture of feature steel alloy provided by the present invention, resistance to salt corrosion, service life is long.Fundamentally
Solve the problem of conventional steels are difficult to use for a long time in the environment of island.The present invention in preparing raw material increase niobium, nickel, copper,
The different metallic element such as cerium, ratio between various composition is have adjusted, so that contain in special steel alloy of the present invention
The elements such as niobium, nickel, copper, the cerium of rational proportion, considerably increase the corrosion resistance of steel, extend its service life.
