What are the main differences between hot rolled flat and cold drawn flat?
The key difference between hot rolled flat steel and cold drawn flat steel is the processing technology. With the development of cold drawn flat steel in hot rolling, its processing accuracy and surface finish are improved gradually.
The working principle of the flat finishing machine is to pre-calibrate and finally calibrate the thickness direction of the cold flat steel wool with two groups of staggered leveling wheels. The width direction is extruded by a pair of relative arrangement of finishing wheels, so that the width is compressed to reach the desired parameters, and the compression amount is adjustable. Use 5 staggered alignment wheels to straighten its width. The system is mainly composed of control box, finishing roller, pre-leveling unit, finishing unit and straightening unit.
Its production process can be summarized as: pre-leveling → finishing → straightening → after leveling. Flat steel/A/B 12-300mm wide, 4-60mm thick, rectangular section with slightly pure edge steel. Flat steel can be finished steel, can also be used as a blank for welding pipe and thin slab for rolling sheet. Main uses: flat steel as a finished material can be used for hoop iron, tools and mechanical parts, as building frame structure, escalator. Flat steel is divided into two kinds according to its shape: flat spring flat steel and single surface double groove spring flat steel. Hot rolled spring flat steel is mainly used in manufacturing automobile, tractor, railway transport and other mechanical leaf springs.

Square steel - square section of steel, hot rolled and cold rolled; Hot rolled square steel side length 5-250mm; Cold-drawn square steel side length 3-100mm.
Round steel - round section of steel, hot rolled, forged and cold drawn three, hot rolled round steel 5-250mm in diameter, which 5-9mm commonly used to do the raw material of the drawing wire, called wire; As a result of the plate supply is also called hot rolled wire rod. Forged round steel straight is thicker, used as shaft blank. Cold-drawn round steel diameter 3-100mm, high dimensional accuracy.
Angle - equilateral Angle and unequal Angle two kinds. Angle steel specifications are indicated by the dimensions of side length and side thickness. Angle bars are usually produced in sizes 2-20, i.e. centimeters of side length. For example, No. 5 equilateral Angle steel refers to the Angle steel with a side length of 5cm (50mm). The same Angle steel often has 2-7 different edge thicknesses.

Jiangsu Irunt Steel Group Co., Ltd. is located in Wuxi City , Jiangsu Province, China, which is the largest steel production base. After 30 years of efforts, it has grown from a family factory to a group company.
