Abstract

The invention relates to the technical field of wire production, and discloses an efficient production method of a phi 12mm wire. The method comprises the following steps that rough refining is carried out; refining is carried out; continuous casting is carried out; heating is carried out; and rolling, polishing and grinding are carried out, wherein a wire solid steel blank obtained after heating sequentially enters a rough mill unit, a finish mill unit and a flying shear unit to obtain a wire steel rolling piece blank, the obtained wire steel rolling piece blank sequentially enters a rough polishing and grinding unit and a finish polishing and grinding unit to be polished and ground, and a wire steel rolling piece is obtained after grinding. According to the efficient production method for the phi 12mm wire, the rolling passes of a pre-finish mill and a finish mill are changed, the rough mill unit is two passes, the finish mill unit is six passes, the finish mill unit is totally provided with two pass patterns, the pass pattern of two of the passes are phi 18, the pass pattern of the other four passes is phi 12, so that the rolling reduction of pre-finish rolling is reduced, the remaining rolling reduction is distributed to the finish mill, and therefore steel heaping accidents caused by speed increase due to large rolling reduction are eradicated, the yield is improved, and speed increase of the finish mill and the pre-finish mill is achieved.

Description

technical field [0001] The invention relates to the technical field of wire rod production, in particular to a high-efficiency production method for a Φ12mm wire rod. Background technique [0002] Wire rod is the smallest section size of hot-rolled section steel. In my country, the hot-rolled round steel supplied in coils with a diameter of 5-9 mm and a total of eight specifications is called wire rod. The concept of wire rod in foreign countries is slightly different from that in my country. There are other shapes besides circular cross-sections. The diameter depends on the demand. It is not consistent with the level of production technology. According to the different rolling mills, it can be divided into high-speed wire rod and ordinary wire rod. The wire rod is generally made of ordinary carbon steel and high-quality carbon steel. [0003] Due to the severe situation of the current steel market, in order to reduce the consumption of various cost indicators, we must reduc...
