Background technique
The corrosion resistance that titanium steel composite board had not only had cladding titanium excellent, but also intensity and plasticity with base's carbon steel, with
Titanium board compare its production cost sharp fall, be manufacture be used for corrosion-resistant environmental unit ideal material, petrochemical industry,
It is used widely in the fields such as salt manufacturing, electric power, sea water desalination, ocean engineering.
Currently, the main preparation methods of titanium steel composite board have explosion composite method, explosion-roll-bonding method and Rolling compund
Method.There are noise pollution and environmental pollutions for explosion composite method, and are affected by weather, and production efficiency is low, be not it is a kind of green,
Environmentally friendly, sustainable production method.For explosion-roll-bonding method using rolling after explosion base, complex process is at high cost.Rolling
Composite algorithm is by assembly, and heated, rolling makes substrate and multiple material realize the production technology of good metallurgical bonding, is had efficient
Rate, industrialized production and can produce the composite metal plate that cladding is thin, wide cut is big at low pollution；But titanium pair in roll-bonding method
The content requirement of the elemental gas such as H, O, N is higher in local environment, is all made of Rolling compund under vacuum state at present；And it is vacuum-treated
Equipment frock and craftsmanship are put forward higher requirements with vacuum-packed reliability.
Summary of the invention
Goal of the invention: the invention discloses a kind of non-real empty state rolling titanium steel composite boards and preparation method thereof, and the titanium steel is multiple
Plywood compound ability is strong, and shear strength is larger；The titanium steel composite board manufacture craft is simple, low to worker and equipment requirement, and makes
Preparation Method is environmentally friendly, efficient.
Technical solution: a kind of non-real empty state rolling titanium steel composite board, including titanium layer, transition zone, carbon steel layer；Transition zone is located at
Between titanium layer and carbon steel layer, and binder course is formed with titanium layer and carbon steel layer respectively；The knot of the transition zone and titanium layer and carbon steel layer
What conjunction ability was greater than the titanium layer and carbon steel layer binds directly ability.
Specifically, above-mentioned transition zone is specially copper, copper alloy, iron, ferroalloy, aluminium, aluminium alloy, nickel, nickel alloy, niobium or niobium
One or more of alloy.
The invention also discloses a kind of preparation methods of non-real empty state rolling titanium steel composite board, include the following steps:
Step 1) selects carbon steel sheet, transition zone and titanium plate, plank is cut to required size, and be surface-treated；
Step 2) prepares interleaving agent；
The one side that titanium plate is smeared interleaving agent by step 3) is staggered relatively, and spot welding is fixed；
Carbon steel sheet, transition zone and titanium plate are stacked gradually placement by step 4), stack sequence successively are as follows: carbon steel sheet, transition zone,
Titanium plate, separation layer, titanium plate, transition zone, carbon steel sheet；
Step 5) forms cavity along carbon steel sheet surrounding soldering and sealing, and reserved venthole simultaneously welds snorkel, the venthole with it is described
Cavity connection, and connect with threeway, threeway one terminates the valve of vacuum pump set, and another terminal strip has the bottled indifferent gas of pressure regulator valve
Body；
Step 6) evacuates chamber air using the snorkel, forms vacuum, then stops vacuumizing and filling into cavity
Inert gas；
Composite plate blanks are heated, are kept the temperature by step 7), compound using milling train calendering, are air-cooled to room temperature and are obtained composite plate；
Composite plate is smoothed composite plate heating, heat preservation by step 8) annealing；
Step 9) cuts off plate head, tail and two sides welding portion, removes separation layer, cleans plate face.
Specifically, above-mentioned steps 2) configuration isolation agent specific steps are as follows: take mesh number to be greater than alumina powder or the oxidation of 40 mesh
Magnesium powder and organic matter powder and water are in (2-3): (1-2): 100 ratio is mixed and stirred for uniformly, and is applied to the non-knot of titanium plate
Baking oven drying is dried or are placed in conjunction face, standing, and oven temperature must not be higher than 180 DEG C；
Specifically, above-mentioned steps 6) specific operation process are as follows: it opens vacuum pump set and is evacuated to 0.01-0.001MPa, close
Unit topping up is closed to normal pressure, it is repeated multiple times so that air content is less than 0.0001MPa in cavity, threeway of dismantling it is same
When snorkel is sealed up with metal plug.
Specifically, above-mentioned steps 7) composite plate blanks are heated to 700-1000 DEG C, 210min is kept the temperature, is rolled using milling train multiple
It closes, first of deformation rate must not be lower than 10%；Repeatedly being rolled total deformation rate is 80%-90%.
Specifically, above-mentioned steps 8) annealing when composite plate is specifically heated to 650-700 DEG C, keep the temperature 30-80min,
Composite plate is smoothed.
Existing vacuum state rolling titanium steel composite board technique is during soldering and sealing, first is that first connect using inert gas-shielded arc welding,
Then it is vacuumized with vacuum pump set more than two-stage, when having taken out vacuum sealing and vacuumizing nozzle, needs to carry out strict control, it cannot
Leak source is generated, operation difficulty is big, more demanding to worker；Second is that using more than vacuum welding equipment realization vacuumizing, welding, seal pipe
The operation such as mouth, although high reliablity, rolling large scale composite plate needs large volume vacuum welding equipment, so that investment is higher, to work
People requires also higher, it is more difficult to operate；The preparation method of non-real empty state rolling titanium steel composite board disclosed by the invention is true using taking out
Empty, applying argon gas, operates repeatedly, rinses cavity, and when air content is lower than requiring horizontal in cavity, institute's filling with inert gas is normal pressure
Or micro-positive pressure, adapter tube valve etc. can be very simply removed, then beyond the Great Wall with metal plug, because working as cavity external and internal pressure one
Outside air will not enter cavity when cause, so reducing the requirement to craftsmanship.
The utility model has the advantages that titanium steel composite board shear strength disclosed by the invention is high, meet standard and processing request；It is of the invention public
Titanium steel composite board preparation method its simple process opened, it is low to worker and equipment requirement without forming vacuum state in cavity, it can
By property height, can industrial volume production, while its preparation process is free from environmental pollution, and alternative existing Explosion composite and vacuum state rolling are multiple
Preparation method is closed, to reduce risk in a manner of existing Explosion composite and to the pollution of environment and vacuum state Rolling compund to work
People's technical ability and the higher requirement of equipment.
