Description
Technical Field
The invention relates to a rolling agent, in particular to a rolling agent for Hi-B steel and a preparation method thereof.
Background
As the requirements for energy conservation and emission reduction are increasingly increasing, the national related departments are considering the energy efficiency upgrading standard of the transformer to be revised and strengthened, in particular the energy efficiency upgrading of the distribution transformer, so that new requirements are put forward for the brands, specifications and performance levels of oriented electrical steel. The amount of general oriented electrical steel (CGO steel) used will gradually decrease in the future, and the amount of high magnetic induction oriented electrical steel (Hi-B steel) used will gradually increase or expand.
Along with the increase of demand of Hi-B steel, the quality requirement on the cold rolled Hi-B steel plate is higher and higher, and particularly the corrosion protection requirement on the rolled plate is higher and higher, so that the invention of a brand new Hi-B steel rolling medium with high corrosion resistance is imperative.
The silicon-iron alloy is characterized in that the silicon content in Hi-B steel is higher, a primary cell is easily formed on the surface of the steel plate by the ferrosilicon alloy, the corrosion resistance potential is reduced along with the increase of the silicon content, so that the ferrosilicon alloy is more easily corroded, and the rolling temperature of the ferrosilicon alloy is different, the yield strength and the tensile strength of the steel are obviously improved along with the increase of the silicon content, and the hardness is correspondingly improved, so that the rolling reduction becomes larger and larger during rolling, the toughness of the material is reduced, crystal grains in the steel plate are easily crushed, the belt breakage phenomenon occurs, and the yield is influenced. Therefore, high-temperature rolling is often adopted to prevent crystal grains from being broken, and when the high-temperature rolling is performed, the temperature of a roll gap area is high, so that the anti-rust additive is required to be strong in adsorption performance and can be firmly adsorbed on a steel plate, a good anti-corrosion effect is achieved, and challenges are presented to the cold-rolled oil of the silicon steel.
The existing rolling medium for Hi-B steel mainly refers to the traditional benzoxazole and sulfonate additives, and when the two types of antirust additives are used in the Hi-B steel rolling process, the defects exist, and the following points are particularly shown:
(1) Because of the particularity of Hi-B steel materials, high-temperature rolling is often adopted to avoid the break-up of the strip and the breakage of grains in the rolling process, and the adsorptivity of the two additives on the metal surface is weakened along with the increase of temperature in the rolling process, so that desorption occurs, and the corrosion prevention effect is reduced.
(2) Because the temperature is high when the Hi-B steel is rolled, the benzoxazole additive can volatilize extremely-smelly smell when being used under high temperature conditions, so that the surrounding environment is polluted;
(3) The sulfonate additive can form metal salt residues on the rolled plate surface, so that the cleaning of the rolled plate surface is influenced, the subsequent annealing is also influenced, and the defective rate of the product is greatly increased.
Based on the above background, it is necessary to devise a new type of rolling medium suitable for Hi-B steels.
The modified triazinic acid utilizes the synergistic effect of ester bond, amido bond and carboxylic acid bond to make the modified triazinic acid be adsorbed on the surface of strip steel so as to form a hydrophobic monomolecular layer with good orientation and compact arrangement, can effectively reduce the transmission capacity of water molecules, oxygen molecules and electrons to the metal surface, can make the critical potential of oxidation of matrix metal be forward moved, and can obviously reduce oxidation-reduction current of the metal surface so as to protect the silicon steel surface, and utilizes the heat stability of amido group and carboxylic acid group to reduce the probability of desorption from the silicon steel surface under the high-temperature condition, and can form a more compact protective layer so as to implement good corrosion-resisting action under the high-temperature rolling condition. The lubricating device has the advantages that the lubricating between the strip steel and the roller is increased, the surfaces of the working roller and the strip steel can be better protected, the quality of the plate surface is improved, the cost of the modified triazinic acid is low, the cost of rolling oil is greatly reduced, the modified triazinic acid is not easy to dissolve in water, and the subsequent sewage treatment is easy to realize.
Disclosure of Invention
In order to solve the above technical problems, the present invention provides a rolling agent for Hi-B steel, wherein the rolling agent for Hi-B steel comprises:
wherein the modified triazinoic acid has the structural formula:
It is worth mentioning that the modified triazinic acid utilizes the heat stability of amide groups and carboxylic acid groups to reduce the probability of desorption from the surface of the silicon steel plate under the high temperature condition, and three functional groups with different polarities, namely ester, amide and acid can well generate synergistic effect to form a more compact protective layer, thereby playing a good role in corrosion resistance under the high temperature rolling condition. In addition, the modified triazine acid utilizes the synergistic adsorption of larger molecular weight, acid, amide and ester bond, and a more efficient and firm adsorption film formed on the surface of silicon steel not only plays a role in corrosion prevention, but also plays a good role in lubrication. Therefore, lubrication between the strip steel and the roller is increased, the surfaces of the working roller and the strip steel can be better protected, and the quality of the plate surface is improved.
In addition, the modified triazinic acid is low in cost, so that the cost of the rolling preparation for Hi-B steel is greatly reduced, and on the other hand, the modified triazinic acid is not easy to dissolve in water and is easy for subsequent sewage treatment.

The rolling agent for Hi-B steel according to a preferred embodiment of the present invention will be described in detail below, wherein the rolling agent for Hi-B steel comprises:
wherein the modified triazinoic acid has the structural formula:
It is worth mentioning that the modified triazinic acid utilizes the heat stability of amide groups and carboxylic acid groups to reduce the probability of desorption from the surface of the silicon steel plate under the high temperature condition, and three functional groups with different polarities, namely ester, amide and acid can well generate synergistic effect to form a more compact protective layer, thereby playing a good role in corrosion resistance under the high temperature rolling condition. In addition, the modified triazine acid utilizes the synergistic adsorption of larger molecular weight, acid, amide and ester bond, and a more efficient and firm adsorption film formed on the surface of silicon steel not only plays a role in corrosion prevention, but also plays a good role in lubrication. Therefore, lubrication between the strip steel and the roller is increased, the surfaces of the working roller and the strip steel can be better protected, and the quality of the plate surface is improved.
In addition, the modified triazinic acid is low in cost, so that the cost of the rolling preparation for Hi-B steel is greatly reduced, and on the other hand, the modified triazinic acid is not easy to dissolve in water and is easy for subsequent sewage treatment.
