First of all, the production of angle steel starts with the preparation of steel billets. Steel billets are produced by steel mills in furnaces Melted and cast. Generally speaking, the materials of angle steel include carbon steel, alloy steel and stainless steel. The quality of the steel billet has an important impact on the quality of the final product. Therefore, it is necessary to ensure that the steel billet meets relevant standards.

The second step is the heating of the billet. The steel billet is heated to a certain temperature in a heat treatment furnace so that it can be formed into the desired angle and shape during subsequent processing. The heating temperature depends on the material and size of the steel billet. After heating, the steel billet is fed into the rolling mill for rolling. Angle steel rolling mill is a piece of equipment specially used for angle steel production. It presses steel billet into the required shape and size. During the rolling process, the steel billet is pressed multiple times through different rolls to gradually form the desired angle and shape. The rolling mill needs to be adjusted according to the requirements of the specific product to ensure the quality and dimensional accuracy of the angle steel. After rolling is completed, the angle steel is cooled through a cooling system. The purpose of cooling is to lower the temperature of the steel and increase its hardness and strength. The cooling method can be natural cooling or water cooling, depending on the requirements of the steel material.

The final step is to trim and cut the angle steel. Trimming is mainly to remove burrs and uneven parts produced during the rolling process to improve the surface quality and appearance of the angle steel. Cutting is to cut the angle steel into the required size according to the length requirements specified by the user.
