Z-direction steel rolling production line for high-rise building

Abstract

The invention relates to a Z-direction steel rolling production line for high-rise buildings, in particular relates to a Z-direction steel rolling production line for high-rise building of Q345GJC-Z15, and the operation mode solves the problem that in the prior art, a lubricant is applied to the surface, but this operation mode increases the operation steps of hot rolling and the consumption of the lubricant is accelerated, the Z-direction steel rolling production line for high-rise building comprises a bottom seat, a guide-in rollers, a hot rolling machine, an upper rollers, a lower roller, alead-out roller, wherein the interior of the second fixing frame is provided with a pair of guide-in rollers through the second motor connection, a hot rolling machine is arranged on the bottom seatclose to the upper end of the second fixing frame, and two upper rollers which are arranged in parallel are arranged in the hot rolling machine, a lower roller is arranged at the opposite end of the upper roller, and a recovery tank is arranged inside the roller close to the lower side of the hot rolling machine, and the third motor can drive the upper side roller and the lower side roller arranged in the hot rolling machine to run along the circumference, hot rolling machining is carried out on the steel sheet which is moved into the hot rolling machine, so that the hot rolling machine playsa role in hot rolling machining on the steel sheet.

Description

technical field [0001] The invention relates to a Z-direction steel rolling production line for high-rise buildings, in particular to a Q345GJC-Z15 Z-direction steel rolling production line for high-rise buildings. Background technique [0002] Z-direction steel, also known as "lamellar tear-resistant steel", is usually called Z-direction performance test steel. Q345GJC-Z15 steel plate is based on a certain level of structural steel (called parent steel), after Specially smelted and treated steel, its sulfur content is less than 1 / 5 of that of general steel, and its section shrinkage is above 15%. The mechanical properties (mainly ductility) of steel plates along the thickness direction are called Z-direction properties. [0003] When the Z-direction steel is processed on the steel rolling production line, the lubricant is applied to the surface before the hot-rolling machine is used to hot-roll the steel plate, but this operation method increases the operation steps of hot ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the shortcomings of using lubricant as surface coating in the prior art, but this operation method increases the operation steps of hot rolling and accelerates the consumption of lubricant, and proposes a high-level Z direction steel rolling production line for construction
