The invention discloses manganese reduction equipment and process for a wire coil production line, and belongs to the technical field of metallurgy. The manganese reduction equipment comprises a heating bay, a main rolling bay and a finished product bay which are sequentially arranged, wherein the main rolling bay comprises a furnace-out roller way, a first rolling mill, a first flying shear, a second rolling mill, a second flying shear, a third rolling mill, a pre-finishing mill group, an initial cooling recovery section, a third flying shear, a horizontal loop, a main finishing mill group, afirst cooling recovery section, a module rolling mill, a second cooling recovery section, a pinch roll, a third cooling recovery section, a laying head and an air cooling line which are sequentiallyconnected. The manganese reduction process is characterized in that a MINI water tank and a 9m / 6m water tank are arranged at proper positions of the production line to carry out dispersed water cooling on a rolled piece, and internal structure crystal grains of the rolled piece is refined by utilizing an online controlled rolling and controlled cooling technology, so that the mechanical property of a finished wire coil product reaches the latest national standard requirement, and the manganese component content of the rolled piece is reduced to 0.6%-0.8% (mass percent), so that the manganese component content of the wire coil product can be greatly reduced, and the production cost of enterprises is reduced.
Description
technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a manganese-reducing equipment and a process for a wire coil screw production line. Background technique [0002] In November 2018, the country issued the latest standards for construction materials. For the old wire coil production line, its production process cannot meet the requirements of the corresponding new national standard. In order to meet the new standard, the production enterprises will increase the amount of alloy manganese added significantly. Manganese The added amount of 1.35~1.4%, even higher, this causes the production cost of the enterprise to increase greatly. Contents of the invention [0003] Purpose of the invention: In order to adapt to the introduction of the latest national standard and reduce the production cost of the enterprise, the present invention provides a manganese-reducing production equipment for the wire coil coil production ...
