Description
Technical field
The invention belongs to corrosion-resisting steel production technical fields, and in particular to a kind of corrosion resistant structural steel production method.
Background technique
Using H profile steel as the mechanism steel mechanical performance and good physical performance of representative, secured, energy saving and environmentally friendly, extensively
For industry, building, bridge, oil drilling platform etc..But acid rain is serious and the region of the seriously corrodeds such as ocean,
In order to which extending structure steel service life must carry out surface anticorrosion processing, common method for anticorrosion treatment mainly has：Coating antiseptic,
Coating anti-corrosion, self-preserving, cathodic protection etc..
Currently, the deficiency of China's steel method for anticorrosion treatment mainly has：（1）For coating antiseptic, coating it is resistance to
Long property is poor, just needs to repair by certain time；（2）For coating anti-corrosion, coating material is non-ferrous metal, though
It so solves the problems, such as durability difference but price is costly, it is uneconomical；（3）For self-preserving, with atmospheric corrosion resistance
Steel as main body, such as weathering steel, although have the characteristics that it is antirust, anticorrosive lengthen the life, be thinned consumption reduction, saving of labor it is energy saving, its price
Costly, and its research belongs to the starting stage in the world, needs further to develop and promote and apply；（4）Benefit
The anti-corrosion mode for reaching anti-corrosion purpose with cathodic protection can expend a large amount of electric energy, for whole system during realization
For will cause very big waste.It is not perfect for current steel method for anticorrosion treatment, and anticorrosion ability is paid no attention to after processing
The situation thought is badly in need of the steel anti-corrosion measure of the problems such as can effectively solve the problem that poor durability, expensive, consuming energy a kind of.
Summary of the invention
In view of the above technical problems, it the present invention provides a kind of corrosion resistant structural steel production method, can be used with extending structure
The service life of steel reduces production cost.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of corrosion resistant structural steel production method, includes the following steps：
Core steel bushing is entered tubulose steel billet by the production of S1, composite blank, and composite blank is made；
S2, the composite blank for obtaining S1 carry out rolling bonding；
S3, the composite blank after combination is vacuum-treated；
S4, the composite blank after vacuum processing is rolled again.
In the S2：Composite blank is heated, makes two kinds of different metal materials in outer masterpiece by rolling after heating
With lower combination.
The vacuum processing refers to：Composite blank after combination is vacuumized, both ends are welded, and two kinds of metals are made
Between without air, prevent from aoxidizing in subsequent process.
In the S4：After composite blank after vacuum processing is heated again, puts it into milling train group and carry out roughing and essence
It rolls.
The core steel is special-shaped steel billet.
The shape of the tubulose steel billet is abnormity, round, ellipse or rectangular.
Compared with prior art, the present invention having an advantageous effect in that：
Ordinary carbon steel price is low, but corrosion resistance is undesirable；Although corrosion-resisting steel has good anti-corrosion effect, but involve great expense.It adopts
With ordinary carbon steel and the compound mode of corrosion-resistant steel, it can play the role of anti-corrosion, and production cost can be reduced.
Using carbon steel as core steel（Substrate）, anti-corrosion steel grade（Tubulose steel billet）As shell, make two parts by extruding means
Engagement, pumps it to vacuum state, welds to both ends；Substrate and shell are combined by rolling means after heating
Integrally, the compound of fashioned iron is realized by rolling after reheating；It can guarantee that two kinds of metals are securely compound by the above method.
