Precision flat steel production process

Flat steel refers to steel with a width of 12-300mm and a thickness of 3-60mm, a rectangular cross section and a slightly blunt edge. The flat steel can be a finished steel, a blank for a welded pipe, and a thin slab for a rolled sheet. Main use: Flat steel can be used as a material to make hoop iron, tools and mechanical parts.  Steel flat bar is used as a structural member and escalator for building.

Precision flat steel production process,The working principle of the flat steel finishing machine is to pre-level and finalize the thickness direction of the cold flat steel wool with two sets of up and down staggered leveling wheels; use a pair of opposite finishing The wheel is squeezed in the width direction so that the width is compressed to achieve the desired parameters, and the amount of compression is adjustable; the width is aligned with 5 staggered alignment wheels. The system is mainly composed of a control box, a finishing press roll, a pre-leveling unit, a finishing unit, and a straightening unit.

Precision flat steel production process

The production process can be summarized as: pre-leveling → finishing → straightening → post leveling. Flat steel / a / b width 12-300mm, thickness 4-60mm, the section is rectangular and slightly with pure edges of the steel. The flat steel can be a finished steel, a blank for a welded pipe, and a thin slab for a rolled sheet. Main use: Flat steel can be used as a material to make hoop iron, tools and mechanical parts. It is used as a structural member and escalator for building. Flat steel is divided into two types according to its shape: flat spring flat steel and single-sided double-groove spring flat steel. Hot-rolled spring flat steel is mainly used to manufacture leaf springs on machinery such as automobiles, tractors, and railway transportation.

Process method for automotive spring flat steel

The spring flat steel is made by a converter smelting process. Compared with the prior art, it has the following advantages and positive effects:

1.Due to the high yield and low power consumption, the cost per ton is lower than that of the electric furnace.

2.The rotary steel is used to refine the flat steel, mainly using molten iron as the raw material. The harmful elements in the molten iron are less, and the quality of the produced flat steel is guaranteed.

3.The continuous casting billet has a high straightening rate, which can ensure the flat steel straightness rate and meet the needs of users.

4.The molten steel is directly cast into a billet, omitting the blanking process and reducing the cost.
