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 straightening 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.
Process method of spring flat steel for automobile
Spring flat steel is made by converter smelting process. Compared with the existing technology, it has the following advantages and positive effects:
1. Flat steel smelting with converter, mainly using hot iron as raw material, hot iron in less harmful elements, the quality of the production of flat steel is guaranteed.
2. Due to high yield, less power consumption, the cost per ton than electric furnace.
3. Molten steel is cast directly into billet, which omits the opening procedure and reduces the cost.
4. Continuous casting billet has high sizing ratio, which can ensure flat steel sizing ratio and meet the needs of users.
