Abstract

The invention relates to a preparation method of a composite steel plate, in particular to a preparation method of a titanium-steel composite plate. The preparation method comprises the following steps of: firstly selecting titanium plates and steel plates which have equal width and length and removing rusty layers and oxide layers; then making surfaces of the titanium plates and the steel plates opposite, and completely coinciding to form a combined blank; then sealing up the periphery of the combined blank by taking four titanium plates as side seal plates, and clamping the side seal plates and the combined blank by using a clamp and then putting the side seal plates and the combined blank into a vacuum chamber together; tightly welding all contact seams of the combined blank and the side seal plates, then conveying the combined blank and the side seal plates into a heating furnace together and heating to 600-1200 DEG C, and carrying out heat preservation for 0.1-2h; and finally, conveying the heated combined blank into a rolling mill for rolling to obtain the titanium-steel composite plate with the interface bonding strength of 350MPa. The invention well solves the problem that the interface of the titanium-steel composite plate is oxidized and improves the interface bonding strength of the composite plate, and moreover, argon or brazing filler metal does not need to be added, thereby saving the cost and simplifying the flow of the production process.

Description

A kind of preparation method of titanium-steel composite board
Technical field
The present invention relates to a kind of preparation method of clad steel plate, be specifically related to a kind of preparation method of titanium-steel composite board.
Background technology
Titanium-steel composite board is widely used in the energy, oil, chemical industry, each industrial department of ocean owing to its excellent corrosion resistance and remarkable economical property.At present, particularly has great application prospect in field of heat exchangers.Employed in the past heat exchanger all is to be processed by pure titanium plate, if pure titanium plate is replaced by titanium-steel composite board, cost will significantly reduce.Therefore, the demand of the titanium-steel composite board of big to size on the market, thin thickness will be very huge.The method of producing titanium-steel composite board mainly is divided into two kinds: a kind of is the blast composite algorithm, and another kind is a roll-bonding method.The composite plate size that the blast composite algorithm is produced is less, is difficult to satisfy customer requirements sometimes, and therefore the blast composite algorithm is usually united use with roll-bonding method at present, so just can produce large-sized titanium-steel composite board.Yet the complex procedures of blast-roll-bonding method, the factor that influences the composite plate bond strength is many, and energy consumption is big, contaminated environment, lumber recovery is low, and this a series of problem has greatly restricted the use of this method; Roll-bonding method can be produced large-sized titanium-steel composite board with comparalive ease, and along with the operation successively of each steel mill at home of the milling train with big roll-force, the application of this method also becomes more and more widely.Roll-bonding method is divided into cold rolling composite algorithm and hot rolling composite algorithm again.Cold rolling composite algorithm is promptly carried out big compression ratio to composite plate below recrystallization temperature rolling, through rolling after annealing compound interface both sides element spread then, to reach the strong bonded at titanium-steel interface.The hot rolling composite algorithm promptly is rolled composite plate after being heated to more than the recrystallization temperature, and compression ratio is cold rolling relatively compound little, need not annealing after rolling.More than two kinds of roll-bonding methods all have certain problem, at first, the big compression ratio of cold rolling composite algorithm requires quite high to roll-force, i.e. infringement to rolled parts is also bigger, so significant limitation is arranged aborning.And the hot rolling method is owing to be at high temperature rolling, and compound interface then is easy to oxidation, and the interface of oxidation has then greatly reduced interface bond strength.Therefore, on the basis of hot rolling method production composite plate, people improve the bond strength of compound interface through the method that reduces the oxidation of hot rolling compound interface.Mainly contain two kinds of methods at present, a kind of is at the nozzle to composite plate heating process and operation of rolling installation protective gas, blows the spray argon gas, to slow down the oxidation at interface; Another kind method is before heating, and the resistant to elevated temperatures solder of coated one deck between titanium plate and the steel plate is to stop the oxidation at interface.Yet what these two kinds of methods were used at present aborning is not very successful, and interface oxidation still exists, and interface shear strength is also lower, about 200MPa.Therefore, control titanium plate surface oxidation is the key problem in technology of titanium-steel hot rolling compounding method.
Summary of the invention
The objective of the invention is deficiency, a kind of preparation method of titanium-steel composite board is provided, solve titanium plate and the problem of oxidation of steel plate interface in the operation of rolling, to obtain interface bond strength titanium-steel composite board preferably to the prior art existence.
The technical scheme that realizes the object of the invention comprises following processing step:
At first choose titanium plate and steel plate that the length and width size equates, remove rusty scale and oxide layer; The titanium plate surface that to remove rusty scale and oxide layer then is relative with the surface of steel plate of removing rusty scale and oxide layer, and overlaps fully, forms the combination blank; Again with four blocks of titanium plates as side seal board seal the combination blank around, and side seal board is put into vacuum chamber after the combination blank clamps with anchor clamps, vacuumize then, when vacuum reaches 1 * 10 -2During Pa, all of combination blank and side seal board contacts seam weldering sternly after, it is sent into jointly is heated to 600 ~ 1200 ℃ in the heating furnace, be incubated 0.1 ~ 2h; To heat at last the combination blank of accomplishing send in the milling train rolling, 550 ℃~1150 ℃ of rolling temperatures, mill speed 0.3 ~ 2m/s, total reduction ratio; 30%, first Dao Ciyaxiashuai>5% obtains Jie Mianjieheqiangdu>The titanium-steel composite board of 350MPa.
Described side seal board is four, and its width all thickness with the combination blank is identical, and wherein the length of two side seal boards is identical with the length of combination blank, and the length of two side seal boards is identical with the width of combination blank in addition.
With use compared with techniques at present, characteristics of the present invention and beneficial effect thereof are:
1, the present invention seals the combination blank owing to having adopted under high vacuum environment; And make the combination blank fast through the heating and rolling after; Reached very firm combination; Compare with the hot rolling composite algorithm with traditional blast composite algorithm, the vacuum sandwich rolling process has solved titanium-steel composite board with flying colors and has prepared the problem of the easy oxidation in process median surface, and the titanium-steel composite board interface shear strength is brought up to from 100MPa>350MPa; This will greatly improve the service life of titanium-steel composite board, further expand the range of application of titanium-steel composite board;
2, hot rolling composite algorithm need to add argon gas or solder, and the present invention need not this processing step, thereby provides cost savings when preventing the titanium-steel composite board interface oxidation, has simplified the technological process of production.
