Abstract

The invention belongs to corrosion-resisting steel production technical fields, and in particular to 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.Ordinary carbon steel price is low, but corrosion resistance is undesirable;Although corrosion-resisting steel has good anti-corrosion effect, but involve great expense.In such a way that ordinary carbon steel and corrosion-resistant steel are compound, 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, two parts are engaged by means such as extruding, vacuum state is pumped it to, both ends is welded;Substrate and shell are combined as a whole by means such as rollings after heating, the compound of fashioned iron is realized by rolling after reheating.

Description

A kind of corrosion resistant structural steel production method

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.

Specific embodiment

The following is a clear and complete description of the technical scheme in the embodiments of the invention, it is clear that described embodiment Only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, the common skill in this field Art personnel every other embodiment obtained without making creative work belongs to the model that the present invention protects It encloses.

A kind of corrosion resistant structural steel production method, includes the following steps:

The production of S1, composite blank:By section configuration core steel as shown in Figure 1(Special-shaped steel billet)After outer surface is cleaned out, set Enter inner surface to clean out in section configuration tubulose steel billet as shown in Figure 2, forms section configuration composite billet as shown in Figure 3 Material.

S2, section configuration composite blank as shown in Figure 3 is heated, it will be such as Fig. 1 institute by rolling mode after heating The special-shaped steel billet shown is combined under external force with tubulose steel billet as shown in Figure 2, in conjunction with section configuration such as Fig. 4 institute of completion Show.

S3, section is combined as shown in Figure 4 later after composite steel billet vacuumized, both ends carry out soldering, protect It demonstrate,proves between deformed steel blank outer surface and tubulose steel billet inner surface as shown in Figure 2 as shown in Figure 1 without air, prevents subsequent process Middle oxidation.

S4, by the steel as shown in Figure 4 of section after the completion of vacuum processing, heated again, put it into and roll after heating Unit carries out roughing, finishing rolling step production becomes corrosion resistance structure steel as shown in Figure 5.

The shape of core steel can be adjusted according to actually required, can be deformed steel base.The shape of tubulose steel billet can be with For special-shaped, round, oval, rectangular or other suitable shapes, as long as no matter which kind of shape core steel bushing can be made to enter i.e. using It can.

Only presently preferred embodiments of the present invention is explained in detail above, but the present invention is not limited to above-described embodiment, Within the knowledge of a person skilled in the art, it can also make without departing from the purpose of the present invention each Kind variation, various change should all be included in the protection scope of the present invention.
