Types of packing

Packing of finished products is carried out in accordance with the requirements of GOST 7566-94, GOST 503-81 and schemes agreed with customer on. According to the normative document a strip coil shall be strapped to a pallet at least in three positions. For corrosion protection strip is coated with a layer of inhibited grease. The delivery of strips without the grease can be agreed with customer individually. Packing can be done both on vertical and horizontal axis.

Vertical axis packing

схема упаковки стальной ленты (вертикальная ось) 1Coils from slitting line, wound on a coiler with plastic or metal strap, are laid on a wooden pallet. If a strip width is less than 50 mm, there shall be at least one strapping through an inner coil diameter, packaging an inner end of the strip.

Strip coils with wooden fillers between are put together in piles. Strips wound on single coilers can be laid without fillers between the coils.

In accordance with the scheme strips are wrapped in packing paper or film and strapped to a pallet by 4 packaging steel straps. To prevent from frontal surface deformation plastic pallets are put under packaging seals. Depending on a packing scheme products can be packed in paper or metal box.

Horizontal axis packing

Required number of CR strip coils with marking tags are laid on a pallet and strapped to each other by one or two radial packaging steel straps (through inner diameter).

Strip coils are set with wooden fillers. Strips wound on single coilers can be set without fillers between the coils.

In accordance with the scheme strips are wrapped in packing paper and strapped to a pallet by 2, and not less than 4 on forming, radial packaging steel straps.

On the face side enter marks and scratches of more than 50 mm length are not allowed.
IIIаNot regulatedThe surface imperfections are not admitted on both surfaces when their depth exceeds half a sum of limit tolerances on thickness. Annealing color is not allowed in the places located more than 200 mm from the edges.
IIIбNot regulatedThe surface imperfections are not admitted on both surfaces when their depth exceeds half a sum of limit tolerances on thickness. Annealing colour is allowed on the whole surface of material

Описание

С целью обеспечения более эффективного раскроя горячекатаного и холоднокатаного рулонного проката производится лента стальная (штрипс). Данный вид продукции получают двумя способами: прокаткой или продольной резкой листовой рулонной стали. Изготовление ленты холоднокатаной основано преимущественно на резке, поскольку на такой вид ленты цена ниже и желающих купить ее гораздо больше. Лента холоднокатаная может выпускаться нагартованной, мягкой, нормальной точности и т.д. Цена на ленту определяется исходя из рыночной стоимости на горячекатаный и холоднокатаный прокат.

Область применения

Горячекатаная и холоднокатаная стальная лента находит применение в следующих сферах:
Штрипс горячекатаный используется для производства труб – электросварных и профильных. Лента хомутная, используемая для стяжки труб, также изготавливается из штрипса.
Стальная лента активно используется для производства продукции для строительства. В частности, штрипс для профиля, производство профильных труб +из штрипса
Лента стальная электротехническая для бронирования кабеля может поставляться оцинкованной, неоцинкованной, нормальной или повышенной точности.
Пружинная холоднокатаная лента производства УМК используется при производстве пружин и инструментов. Более мягкий рулонный штрипс (гибкая стальная лента) используется для штамповки деталей машин и оборудования.
Производство ленты холоднокатаной в значительной мере ориентировано на изготовление упаковочных, обвязочных и бандажных материалов. Обвязка стальной лентой осуществляется специальным оборудованием и инструментами, купить которые можно в нашей компании (подробнее см. «Упаковочный инструмент»).
