Description

A rust cleaning device for cold-formed H shaped steel

Technical Field

The utility model relates to a cold-formed technical field specifically is a rust cleaning device for cold-formed H shaped steel.

Background

The cold-rolled section steel is various complicated section bars which are made by hot-rolled or cold-rolled strip steel as raw materials and by pressure processing at normal temperature. Also called thin-wall section steel, is one of light building structural steel. The production of cold-formed steel has been for over 100 years, and the single-machine production of the cold-formed steel is originally adopted by a bending press. In 1910, the first continuous roll forming unit was first built in the United states. After 1960, cold-formed steel is rapidly developed, the annual output of the world reaches 800 ten thousand at 1989, and the specification of the variety is more than 10000. The yield of cold-formed steel in industrially developed countries accounts for about 5% of the total yield of steel. In 1958, china built the first set of cold-formed steel production unit in Shanghai, and more than 30 forming units exist at the end of 80 years, and cold-formed steel with nearly 100 varieties and annual output of more than 20 ten thousand is produced. Cold-formed steel is an economical section of light thin-walled steel, also called steel cold-formed section or cold-formed section. The cold-formed steel is the main material for manufacturing light steel structures. It has various very thin, reasonable and complicated cross sections which can not be produced by hot rolling. Compared with hot rolled section steel, under the condition of the same section area, the gyration radius can be increased by 50 percent to 60 percent, the section inertia moment can be increased by 0.5 to 3.0 times, and therefore, the material strength can be reasonably utilized; compared with the common steel structure (i.e. the steel structure made of the traditional I-shaped steel, channel steel, angle steel and steel plate), the steel can be saved by about 30-50%. In some cases, the steel consumption of the cold-formed steel structure is equivalent to that of a reinforced concrete structure under the same condition, and the cold-formed steel structure is an economic section steel.

One kind of H shaped steel all can have a large amount of iron rusts before the cold-formed on the base material especially, need polish the rust cleaning to shaped steel in order to guarantee the shaped steel quality after the cold-formed and carry out the cold-formed work again, the tradition is polished shaped steel and is adopted the workman to polish with the buffing machine, and the quality of polishing is relatively poor, and the phenomenon that some places were polished inadequately or excessively polished appears.
