Classification by production method


Release time:

2022-08-12

Profiles can be divided into hot-rolled profiles, cold-formed profiles, cold-rolled profiles, cold-drawn profiles, extruded profiles, forged profiles, hot-bent profiles, welded profiles and special rolled profiles, etc.

(1) Classification by production method

Profiles can be divided into hot-rolled profiles, cold-formed profiles, cold-rolled profiles, cold-drawn profiles, extruded profiles, forged profiles, hot-bent profiles, welded profiles and special rolled profiles, etc.

(2) Classification by sectional characteristics

Profiles can be divided into simple profiles and complex profiles according to their cross-sectional shapes. Simple section profile cross section symmetry, appearance is more uniform, simple, such as round steel, wire, square steel and flat steel, etc. Complex section profiles, also known as special-shaped section profiles, are characterized by cross sections with obvious convex and concave branches. Therefore, it can be further divided into flange profiles, multi-step profiles, wide and thin profiles, local special processing profiles, irregular curve profiles, composite profiles, periodic section profiles and wire materials and so on.

(3) Classification by department of use

According to the use of department, there are railway profiles (rail, fishtail plate, switch rail, wheel, hoop), automobile profiles (rim, tire rear-ring and lock ring), shipbuilding profiles (L section steel, ball flat steel, Z steel, Marine window frame steel), structural and architectural profiles (H section steel, I beam steel, channel steel, Angle steel, crane rail, window frame and door frame materials, steel sheet pile, etc.), Mine steel (U section steel, groove side steel, mine I beam steel, scraper steel, etc.), special profile for machinery manufacturing, etc.

(4) Classification by section size

Profiles can be divided into large, medium and small profiles according to section size, which are usually classified according to their suitability for rolling on large, medium and small rolling mills respectively. The distinction between large, medium, and small is actually not strict. There is also a way to distinguish by a single weight (kg/m). It is generally believed that the single weight below 5 kg/m is the small profile, the single weight in 5 ~ 20 kg/m is the profile, the single weight more than 20 kg/m is the large profile.
