AI Technical Summary

Technical Problem

There are diameter fluctuations and steel breakage problems in the production process of hot-rolled disc strips of existing carbon structural steel, resulting in poor production quality, high cost and low efficiency.

Method used

A method of producing hot-rolled disc strips of carbon structural steel is adopted, including billet heating, descaling before rolling, rolling, cutting head and tail cutting, cooling control and compression and bundling of wire coils. By setting reasonable parameters, such as wire spinning temperature, oven-output pinch roller speed and cooling control parameters, combined with constant microtension rolling and hole-type system design of a twistless wire rolling mill, the stability and quality of the production process are ensured.

Benefits of technology

It reduces the opening rolling temperature, reduces metal oxidation loss and energy consumption, ensures the strength of the billet, improves product quality, reduces production costs, improves production efficiency, and avoids the steel breakage problem of the strip.

Abstract

The invention relates to the technical field of wire rod smelting, and particularly discloses a production method of a carbon structural steel hot-rolled round wire rod, which comprises the following steps: heating a steel billet: setting the initial rolling temperature of carbon structural steel to be 900-980 DEG C, and setting parameters of spinning temperature, tapping pinch roll speed, tapping pinch roll advance rate and tapping roller way speed; descaling before rolling: setting high-pressure water for descaling; rolling, wherein constant micro-tension rolling is conducted through a twist-free wire rod rolling mill; cutting heads and tails after rolling: setting shearing parameters of a No.1 flying shear, a No.2 flying shear and a No.3 flying shear; controlled cooling: setting a water cooling parameter, an air cooling parameter and a silking machine control parameter; pressing and bundling of wire coils: because most of the wires produced by a twist-free wire rolling mill are large-coil heavy products, the coils are collected by controlling the cooling temperature to be lower than 400 DEG C, the coils are bulky, and pressing and bundling must be carried out; the steel wire rod diameter consistency is guaranteed, steel breakage of the steel wire rod is avoided, the product quality is improved, the production cost is reduced, and the production efficiency is improved.
