Hot-dip galvanized strip steel production system

Abstract

The invention proposes a hot-dip galvanized strip steel production system. The hot-dip galvanized strip steel production system comprises a strip steel storage warehouse, a S roller set, a conveying roller, a tension extension roller set, an annealing furnace, a zinc galvanizing tank, an insulation system, a cooling system, a traction collecting roller, and a monitoring roller arranged between the S roller set and the conveying roller; the monitoring roller is driven by strip steel to rotate; one end of a rotating shaft of the monitoring roller is connected with a rotating encoder through a coupling; and the rotating encoder is connected with a host machine. The hot-dip galvanized strip steel production system can timely and automatically stop in rupture of the strip steel through setting the monitoring roller, is convenient for operators to connect the strip steel to quickly recover production, improves the production efficiency, largely reduces the labor maintenance cost, and prevents the production loss; and through design of the cooling roller, the wire arrangement space and the production cost are saved.

Description

technical field [0001] The invention relates to the technical field of strip steel production used in plastic-coated metal hoses, in particular to a hot-dip galvanized steel strip production system used in plastic-coated metal hoses. Background technique [0002] The plastic-coated metal hose is made of polyvinyl chloride material on the pipe wall of the stainless steel hose or galvanized metal hose, along the uneven surface of the pipe wall core with a layer of cable. Due to its light weight, excellent flexibility, corrosion resistance and high temperature resistance, strong tensile strength, and high connection strength with accessories, the plastic-coated metal hose is widely used in electric power, chemical industry, metallurgy, light industry, machinery and other industries. Wires, cables, wire and cable protection tubes for automation instrument signals, etc. [0003] In order to improve the performance of plastic-coated metal hoses and meet higher requirements for us...

AI Technical Summary

Problems solved by technology

The length of the entire production line is relatively long. The annealing furnace, galvanizing tank, and heat preservation tank are all high-temperature closed equipment, and the thickness of the strip steel used in the plastic-coated metal hose is very thin, generally only about 0.5mm. Driven by the tractor, if If there are quality defects in the strip steel, it is easier to be broken. If the breakage occurs in closed stations such as annealing furnace, galvanizing tank, and heat preservation tank, the operator cannot find it immediately. When it is found, the breaking distance is already relatively long It is very difficult for operators to connect the disconnected steel strips, especially through high-temperature annealing furnaces, galvanizing tanks, etc. to connect the strips, which is more time-consuming and laborious. Once this happens, it often takes several hours. Resumption of production seriously affected the efficiency of the galvanizing production line
