Изобретение относитс к обработке металлов давлением и может быть использовано в процессах гор чей прокатки , штамповки и прессовани .The invention relates to the processing of metals by pressure and can be used in the processes of hot rolling, stamping and pressing.
Целью изобретени вл етс npefloiv вращение сваривани листов при нагреве и попарной прокатке.The aim of the invention is to npefloiv the rotation of the welding of sheets during heating and pairwise rolling.
Состав дл нанесени на поверх- но.ать стальных листов перед гор чей прокаткой, содержащий хлористый натрий и воду, дополнительно содержит сернокислое железо при следующем сооношении компонентов, %:The composition for deposition on the surface of steel sheets before hot rolling, containing sodium chloride and water, additionally contains ferrous sulphate at the following combination of components,%:
Хлористый натрий 10-21Sodium chloride 10-21

Верхний предел концентраций соот- йетствует насьщенному раствору, нижний - минимальной концентрации, обеспечивающей достаточно высокий выход годного. Хлористый натрий и железный купорос обладают хорошей растворимостью в воде. Смесь растворов этих веществ обладает низкой в зкостью, легко проникает между листами сутунки , хорошо их смачив т. На воздухе предлагаемый раствор частично тер ет воду и образует на поверхности сутунThe upper concentration limit corresponds to the nascent solution, the lower one - to the minimum concentration, which ensures a sufficiently high yield. Sodium chloride and blue vitriol have good solubility in water. The mixture of solutions of these substances has a low viscosity, easily penetrates between the sheets of the petunks, and they are well wetted.

с образованием мелкодисперсного магнетита . Хлористый натрий частично улетучиваетс ,with the formation of fine magnetite. Sodium chloride partially volatilizes
Таким образом, перед прокаткой на поверхности сутунки находитс пленка расплавленного хлористого натри , содержаща мелкодисперсный магнетит . При прокатке расплав хлористого натри играет роль смазки, а магнетит вл етс теплоизолирующей прокладкой, раздел ющей сначала поверхности валка и проката, а при попарной прокатке - вновь образующиес поверхности стального листа.Thus, before rolling, a film of molten sodium chloride containing finely dispersed magnetite is on the surface of the shimmer. During rolling, the sodium chloride melt plays the role of a lubricant, and magnetite is a heat-insulating gasket separating first the surfaces of the roll and rolled products, and when pairwise rolling, the newly formed surfaces of the steel sheet.
На металлургических заводах железный купорос вл етс продуктом регенерации сернокислых травильных растворов. В св зи с этим использование предлагаемого состава дл пре - дотвращени сваривани листов при попарной прокатке практически не требует дополнительных затрат.In metallurgical plants, iron sulphate is the product of the regeneration of sulphate pickling solutions. In this regard, the use of the proposed composition to prevent the welding of sheets during twin-roll rolling requires practically no additional costs.
