The technological process of flat steel
The spring flat steel is made by converter smelting process. Compared with the prior art, the utility model has the following advantages and positive effects:1. refining flat steel with converter, mainly using hot metal as raw material, less harmful elements in molten iron, the quality of flat steel produced is guaranteed.2., because of the high rate of finished products and less power consumption, the cost per ton is lower than that of the electric furnace.3. the molten steel is directly cast into billets, omitting the cogging process and reducing the cost.4., continuous casting billet, fixed rate is high, can ensure flat steel fixed rate, to meet the needs of users.
The production process can be summarized as: pre leveling, finishing, straightening and leveling. Flat /a/b width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings. Flat steel is divided into two kinds according to its shape: flat spring, flat steel and single side double slot spring flat steel. Hot rolled spring flat steel is mainly used in the manufacture of automobiles, tractors, railway transportation and other mechanical leaf springs.
The working principle of precision steel production process of flat steel finishing machine is cold flat bad hair with two sets of upper and lower staggered leveling wheel thickness pre leveling and final leveling; with a pair of oppositely disposed finishing wheel in the width direction of extrusion, the width is compressed and reaches the expected parameters and the amount of compression can be adjusted; with 5 aspects of straightening straightening wheel arrangement of the staggered width. This system is mainly composed of a control box, finishing roller, pre leveling unit, finishing unit, straightening unit.
