Description

Известные способы эмалировани  труб из среднеуглеродпстой стали трудоемки и не обеспечивают достаточно прочного сценлени  эмали с материалом труб. Примен емые установки дл  эмалировани  труб не позвол ют организовать поточного производства.The known methods of enameling medium-carbon steel pipes are laborious and do not provide a sufficiently strong enamel scene with the material of the pipes. The enamel installations used for pipes do not allow the organization of in-line production.

Описываемый способ, предусматривающий очистку и обезжиривание поверхности труб, нанесение рифлений и цинконикелевого подсло , натирание пастой, покрытие шликером, сушку и обжиг нанесенного сло , позвол ет значительно снизить затрату труда, повысить производительность и улучшить сцепл емость эмали с основой.The described method, which involves cleaning and degreasing the surface of pipes, applying corrugations and a zinc-nickel undercoat, rubbing with a paste, coating with a slip, drying and firing the applied layer, can significantly reduce labor costs, improve productivity and improve adhesion of enamel to the base.

Достигаетс  это тем, что нарифлени  на наружную поверхность труб нанос т путем их дробеструйной обработки мелкой дробью, а дл  сушки шликера примен ют терморадиационный способ нагрева.This is achieved by the fact that the pipes are applied to the outer surface of the pipes by means of their shot-blasting treatment with small fractions, and a thermoradiation method of heating is used to dry the slurry.

Описываема  установка дл  осуш,ествлени  способа позвол ет организовать непрерывный поточный технологический процесс за счет того , что она снабжена приспособлением дл  сортировки труб по размерам , а дл  сочленени  обрабатываемых труб в единую пить применены двухсторонние патроны с отжимаюш,имис  щекалп.The described plant for drying, the method allows to organize a continuous flow process due to the fact that it is equipped with a device for sorting pipes by size, and for joining the pipes to be processed into a single drink, double-sided chucks are used, they are cheeked.

Сущность описываемого способа эмалировани  заключаетс  в следующем . Автоматически подаваемые трубы сортируютс  на сортировочном приспособлепии, причем трубы нестандартного размера отдел ютс  и вывод тс  из технологического цикла. Трубы стандартных размеров после их соединени  в одну нить подвергаютс  очистке и дробеструйной обработке крупной дробью, а затем на их наруж;ную поверхность нанос т нарифлени  быстро вращающимис  стальными щетками и дробеструйной обработкой мелкой дробью. После этого поверхность труб подвергают химической очистке и на нее нанос т контактным способом пленку из цинконикелевого сплава, преп тствующую быстрому окислению поверхности трубы. После сушки гор чим воздухом на поверхность труб натиранием нанос т эмаль-пасту, которую сущат терморадиационным способом. Затем трубы нагревают в глдукторе до оплавлени  наружного сло  покрыти . На оплавленный слой распылением нанос т слой, грунтовой эмали, вторично нагревают трубрл токами высокой частоты, и покрывают трубу слоем покровной эмали.The essence of the enamelling method described is as follows. The automatically fed tubes are sorted on a sorting device, with non-standard sized pipes being separated and removed from the process cycle. Pipes of standard sizes, after their connection into one thread, are subjected to cleaning and shot-blasting with coarse shot, and then on their outer surface, they are applied to the surface with rapidly rotating steel brushes and shot-blasting with fine shot. After that, the surface of the tubes is subjected to chemical cleaning and a zinc-nickel alloy film is applied to it in a contact manner, which prevents the tube surface from oxidizing rapidly. After drying with hot air, the enamel paste, which is thermally radiated, is applied to the surface of the pipes by rubbing. The pipes are then heated in the glider until the outer layer of the coating melts. A layer of ground enamel is applied to the melted layer by spraying, the pipes are again heated with high-frequency currents, and the pipe is covered with a layer of coating enamel.
