Abstract

The invention discloses a system for cold rolling, dephosphorizing and lubricating steel bars and a cold rolling process thereof and belongs to the technical field of cold rolling equipment of steel bars. The system for cold rolling, dephosphorizing and lubricating steel bars comprises a guide frame, a dephosphorizing device and a lubricating device which are arranged along a forward direction, wherein the guide frame comprises support rods, circular rings and support legs; the circular rings are different in sizes and are parallel arranged from large to small in a convergent shape along the forward direction; the support rods are axially fixed at the periphery of the circular rings and are used for connecting the circular rings together; two support legs are respectively fixed at the bottoms of the circular ring at the head and the circular rings at the tail; the dephosphorizing device comprises an inlet A, a dephosphorizing mechanism, a case A, a waste outlet, an outlet and support legs; the lubricating device comprises a hopper, an inlet B, a case B and rollers; the inlet A, the outlet and the inlet B are arranged on a straight line. The system is long in service life, low in production cost and simple to operate, is capable of continuously producing and avoiding the raising dust pollution.

Description

technical field [0001] The invention relates to the technical field of steel bar cold rolling equipment, in particular to a steel bar cold rolling dephosphorization-lubricating system and a cold rolling process thereof. Background technique [0002] The cold-rolled steel bar mill is a special equipment for rolling steel bars. The rolled steel bars are usually completed on a special production line for rolling steel bars. For example, the cold-rolled ribbed steel bar production line is used to cold-roll the hot-rolled grade I steel bar HRB235 into new The national standard is the production equipment of CRB550 cold-rolled ribbed steel bar. The cold-rolled ribbed steel bar production line includes a phosphorus removal device. The purpose of setting the phosphorus removal device in the production line is to wind the hot-rolled grade I steel bar between the phosphorus removal rollers, and the running steel bar passes through friction with the rollers, so that Impurities such as...
