Abstract
A kind of sandwich rolling process produces slab carbon steel plate slab mating surface preprocess method, comprises the steps: 1) slave board, make the slab that two stock material, length and width are equal；2) scale on surface is removed；3) surface special handling, the faying face surface to one block of slab in two boards base, use milling machine mode that it is carried out surface roughness and control processing, processing rear surface roughness Ra is 0.16 0.32 μm；Or, using planer mode that it is carried out surface roughness and control processing, after processing, roughness Ra is 5 50 μm；Another block slab faying face surface using planer mode carry out surface roughness and controls processing, processing rear surface roughness Ra is 50 500 μm.The present invention under conditions of not using vacuum chamber, can maintain during assembly the purpose of vacuum in reaching slab, and so that slab faying face has fine structure, can improve upper and lower slab contact surface joint efficiency in the operation of rolling.
Description
Technical field
The present invention relates to thick composite plate manufacturing technology field, produce thickness particularly to a kind of sandwich rolling process
Plate carbon steel plate slab mating surface preprocess method.
Background technology
Currently, there have been composite rolling technology in domestic and international some iron and steel enterprises, are realizing composite rolling
Before technology, it is necessary to slab is carried out composite billet pretreatment, the cleaning of the mating surface of slab is also must be through
The critical process path crossed.
In the most widely used composite rolling produces slab technology, the plate before composite billet pretreatment
The surface pretreatment of base is to remove iron scale, and does not comprise the control to surface roughness.
Under the conditions of this process route, follow-up through in vacuum chamber assembly welding after composite billet rolling time,
Its joint efficiency can reach user's requirement.The technology of the present invention processes at continuous casting billet scale on surface
Time, adding surface roughness control, the composite billet after assembly need not be welded by assembly in vacuum chamber
Connect, combined efficiency can be improved in the operation of rolling further.
Summary of the invention
It is an object of the invention to provide a kind of sandwich rolling process production slab carbon steel plate slab and combine table
Face preprocess method, it is possible under conditions of not using vacuum chamber, reaches in slab during assembly
Maintain the purpose of vacuum, and, the control of surface roughness makes slab faying face have fine structure,
In the operation of rolling, these fine structures of upper and lower slab contact surface form trickle contact, it is thus achieved that bigger
Rolling stress concentrate, thus improve joint efficiency.
For reaching above-mentioned purpose, the technical scheme is that
A kind of sandwich rolling process produces slab carbon steel plate slab mating surface preprocess method, including as follows
Step:
1) slave board
Make the slab that two stock material, length and width are equal；
2) scale on surface is removed
Use Mechanical Method that the faying face scale on surface of two boards base is cleaned out；
3) special handling on surface
Faying face surface to one block of slab in two boards base, uses the mode of milling machine,
It is carried out rough surface processing, and the surface roughness after processing is
0.16μm-0.32μm；Or, use the mode of planer, it carried out rough surface
Processing, the roughness after processing is 5 μm-50 μm；
Faying face surface to another block slab, uses the mode of planer, it is carried out table
Face roughening processing, the surface roughness after processing is 50 μm-500 μm.
The present invention is by adjusting machining equipment (milling machine, planer) parameter, coarse to steel slab surface
Degree scope is controlled, remote (the milling machine processing essence not in GB/T1031 critical field of its processing mode
Degree is IT9-IT8, Ra6.3～Ra1.6；Planer machining accuracy is IT9～IT8, Ra25～Ra1.6), and
Realize with group two boards base difference in surface roughness.
The present invention is not under conditions of utilizing vacuum chamber, merely with simple vacuum machine, same by the present invention
Sample can realize extraction and maintain the vacuum at slab combination interface.And the slab after removing surface is carried out
After assembly welding, the operation of rolling gives full play to the effect of surface roughness, improve interface cohesion effect
Rate.During the present invention is contemplated to realize the pretreatment base needed for slab composite rolling, in order to realize
Under the conditions of vacuum chamber, the surrounding of composite billet is not welded and efficiently realizes and maintain in the middle of two boards base
Vacuum state before, the special surface that carried out steel slab surface processes.
The invention has the beneficial effects as follows:
Slab after being processed by the technology of the present invention, carries out the control of roughness to its surface, on the one hand,
Under conditions of not using vacuum chamber, it is possible to maintain the mesh of vacuum in reaching slab during assembly
, still further aspect, the control of surface roughness makes slab faying face have fine structure, in rolling
During, these fine structures of upper and lower slab contact surface form trickle contact, it is thus achieved that bigger rolling
Stress is concentrated, thus improves joint efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Seeing Fig. 1, the sandwich rolling process of the present invention produces slab carbon steel plate slab mating surface pretreatment
Method, comprises the steps:
1) slave board
Make the slab that two stock material, length and width are equal；
2) scale on surface is removed
Use Mechanical Method that the faying face scale on surface of two boards base is cleaned out；
3) special handling on surface
Faying face surface to one block of slab 1 in two boards base, uses the side of milling machine
Formula, carries out rough surface processing to it, and the surface roughness after processing is 0.2 μm；
Or, use the mode of planer, it is carried out rough surface processing, thick after processing
Rugosity is 23 μm；A is the faying face of slab 1,2；
Faying face surface to another block slab 2, uses the mode of planer, carries out it
Rough surfaceization is processed, and the surface roughness after processing is respectively 87 μm and 125 μm.
Having prepared 2 groups of composite billets in the embodiment of the present invention, after its composite billet removing surface, parameter sees table
1。
It is heated to 1200 DEG C, by identical rolling work after soaking in 2 groups of composite billets are placed heating furnace
Skill rolls, and detects a flaw the composite plate after rolling, and result shows, is processed by surface of the present invention
Slab, all can realize Rolling compund after rolling.
