The technology of hot rolling mill is to connect the two processes of solidification and deformation of steel, and continuously send the continuous casting slab to the finishing mill in the hot state to directly roll the strip into the coil product.

The technology of direct rolling without heating of bar and wire refers to the technology of directly sending the slab with residual heat after continuous casting into the rolling mill line for rolling. When the heating-free process is used, the billet does not need to be heated in the furnace, and it does not need to be reheated (some of which replenishes the corner parts through the electromagnetic induction device), completely eliminating the fuel consumption of the heating furnace, which can greatly save energy and reduce carbon dioxide of emissions.

Due to the rolling force of the rolling mill, its adjustment of the screw nut up and down will be affected to varying degrees, and one of the possible consequences is the automatic unscrewing of the screw in the rolling mill. Under normal circumstances, the automatic unscrewing of the screw is mainly produced on the blooming mill and the strip rough rolling mill.

The wire rod mill is a rolling mill dedicated to rolling wire rods. The wire rod is the product with the smallest cross-section in profile steel. Rolling from a billet into the finished product, the total elongation coefficient is large. The rolling stock is often rolled only once on each rolling mill machine. Therefore, the wire rolling mill has the largest number of racks and the finest division of labor in the hot-rolled profiles.

Hot billet, cold billet → inspection → rejection of unqualified billet→ heating in furnace → descaling by high pressure water →rejection of unqualified billet → roughing rolling(φ550*6) → No. 1 crank flying shear → medium rolling(φ450*6) → No. 2 rotary flying shear → finishing rolling (φ350*6) → water cooling →No. 3 complex crank flying shear → cooling on cooling bed → 850 T cold shear cut to length → fixed-length flying shear counting →bundling, packing → weighing, welding tag, counting →warehousing and delivery
