Abstract
The invention discloses an isolation paint for manufacturing a stainless steel composite plate by symmetrical hot rolling, belonging to a hot rolling plate auxiliary material technology field, wherein the isolation paint contains the following components by weight: 10-20% of silica, 20-30% of alcohol, and 50-70% of distilled water, wherein the particle size of the silica is 10-50mum, and the ethanol content of the alcohol is 99%. The preparation method comprises: adding silica, alcohol and distilled water into a container with a stirrer according to the percentage proportion, and stirring in a rotation speed of 1500r/min for 7-8min, to obtain the isolation paint. Isolation effect is good after hot-rolling two stainless steel plates coated by the isolation paint, and isolation paint not only solves a hot rolling composite deformation uneven problem by a symmetric assembling manner, but also raises production efficiency.
Description
Technical field
The present invention relates to a kind of symmetrical hot rolling and manufacture the barrier coating of stainless steel clad plate, belong to hot-rolled sheet subsidiary material technical field.
Background technology
Stainless steel clad plate refers to the stainless steel double layer of compound last layer thinner thickness on the single or double of the mild steel plate of thicker specification, is the current larger a kind of laminate structure metal composite of usage quantity in the world.Stainless steel clad plate has stainless high-corrosion resistance and the good mechanical property of soft steel concurrently, is mainly used in the Grand Equipments industries such as petrochemical complex, oceanographic engineering, generating, shipbuilding and high quality oils letter shoot line.In stainless steel clad plate, stainless weight accounts for 1/10-1/5 left and right, than alloying element consumptions such as the Cr of individual layer stainless steel plate, Ni, reduces 70-80%, overall cost 30-50%.
Traditional stainless steel clad plate manufacture method mainly contains blast composite algorithm, casting composite algorithm and roll-bonding method.Efficiency is high, bonding properties is good owing to having for hot rolling composite algorithm, good stability, product specification are large etc., and feature has become the main method of producing in the world stainless steel clad plate; The method is clean by stainless steel plate to be composite and mild steel plate removing surface, together with the face to be composite of stainless steel plate and mild steel plate is superimposed with each other, welding is obturaged and reserved aperture vacuumizes, after vacuumizing, aperture is sealed, then send into and in process furnace, heat and be rolled, obtain the composition board of stainless steel and soft steel, be called for short stainless steel clad plate.Because stainless steel is different from intensity and the deformability of soft steel, therefore in rolling recombination process, can produce inhomogeneous distortion, also can make in composition board stainless steel wayward with the thickness proportion of soft steel simultaneously, thereby greatly increase the difficulty of composition board plate shape control.This distortion non-uniform phenomenon can be improved and be solved by the method for symmetrical assembly, the unitized construction that is soft steel/stainless steel compound blank-isolated material-stainless steel/soft steel composite blank solves the assymmetrical deformation problem in the operation of rolling, and isolation technology is wherein the gordian technique that stainless steel clad plate is manufactured in symmetrical hot rolling.
Summary of the invention
In order to overcome above-mentioned technical deficiency, the invention provides a kind of symmetrical hot rolling and manufacture the barrier coating of stainless steel clad plate, this barrier coating can effectively be isolated stainless steel and stainless combination in composite plate blanks in course of hot rolling, thereby the symmetrical sandwich after making to roll can be divided into two into two composite board product.
The present invention solves the technical scheme that its technical barrier adopts: barrier coating is comprised of following weight per-cent component:
Silica 1 0%--20% alcohol 20%--30% distilled water 50%--70%.
Silicon-dioxide: particle diameter 10-20 μ m.
Alcohol: ethanol content 99%.
Its preparation method: silicon-dioxide, alcohol, distilled water precentagewise ratio are put into the container with agitator, and rotating speed is: per minute 1500 turns, stirs 7-8 minute.Become barrier coating.
The invention has the beneficial effects as follows: after adopting barrier coating brushing two stainless hot-rolled steel plates, isolation effect is good, utilize the mode of symmetrical assembly not only to solve the problem of hot rolling composite deformation inequality, also improved production efficiency simultaneously.
