Arrangement scheme of high-speed wire cutting production process

Abstract

The invention relates to the technical field of steel rolling in the metallurgical industry, in particular to an arrangement scheme of a cutting high-speed wire production process, which comprises the following steps: S1, when the temperature of a qualified continuous casting billet produced by a continuous casting machine meets the continuous casting direct rolling requirement, directly conveying the qualified continuous casting billet to a roughing mill unit through a rapid roller way; s2, rolling the rolled piece for 6-8 passes in the rough rolling unit, and then conveying the rolled piece to an intermediate rolling unit after the rolled piece passes through a flying shear head; s3, after the rolled piece is rolled for 4-7 passes in the intermediate rolling unit, the rolled piece passes through a flying shear head and then is conveyed to a pre-finishing rolling unit; s4, the rolled piece is cut in a pre-finishing rolling unit, and the rolled piece is divided into two parts; compared with the prior art, a rolled piece is cut into two independent rolled pieces with the same sectional area in the pre-finish rolling pass, so that a production line can directly machine billets with large sections and original lengths, the production yield is greatly improved, meanwhile, multiple rolling procedures of the rolled piece are replaced by cutting, the production procedures are greatly saved, the production energy consumption is reduced, and the production cost is reduced. The production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of steel rolling in the metallurgical industry, in particular to an arrangement scheme of a cutting high-wire production process. Background technique [0002] At present, there are two main layout schemes for wire rod production. The first is the high-speed wire rod production line, which consists of heating furnace, rough rolling unit + cutting head flying shear, middle rolling group + cutting head flying shear + (pre-water piercer), pre-finishing rolling Unit + high-speed flying shear + water penetrator, finishing rolling unit + water penetrator + (reducing and sizing unit + water penetrator), laying machine, control cooling line, coil collector, compressing machine, P-F line. The second type is a double high-speed wire rod production line, commonly known as AB line, in which the rough rolling unit has 1 to 4 passes after rolling for 4 passes, and then passes through the steel dividing device, and then en...
