Abstract

The invention relates to a hot-rolled steel bar MG400 preparation method based on an electric furnace smelting resin anchor rod. The method comprises the following steps that S1, a pretreated steel billet is transmitted to a pre-rolling device through a first transmission device, is rolled by the pre-rolling device, and is transmitted to a position above a heating furnace through a second transmission device; S2, a pre-rolled steel billet is cut into a preset cut steel billet length through a cutting device arranged above the heating furnace, and the cut steel billet is injected into the heating furnace to be heated; S4, the rolled steel billet is cooled through a cooling device and then pulled to a straightening device to be straightened; and S5, a central control unit judges that a to-be-detected steel bar is subjected to mechanical property detection. The central control unit is arranged, and the preset cut steel billet length, the rolling force of the rolling device and the cooling efficiency are adjusted through the central control unit, so that the mechanical property of the produced steel bar meets the preset standard.

Description

technical field [0001] The invention relates to the field of steel bar preparation, in particular to a method for preparing hot-rolled steel bar MG400 based on electric furnace smelting resin anchor rods. Background technique [0002] With the rapid development of the construction industry, complex structures such as large public buildings and high-rise buildings have higher and higher requirements for the bearing capacity of steel bars, requiring steel bars to have higher comprehensive properties such as higher strength, toughness, and better weldability. , hot-rolled resin anchor bars are mainly used in the bolting of coal mine shafts and tunnels. Bolting is an important support technology widely used. Coal roadway bolting technology has developed extremely rapidly in recent years, and High strength, high stiffness and high reliability have become a development trend. This support system has obvious advantages in improving the roadway support effect, ensuring the safety o...
