Ribbed steel bar short-circuit heat treatment equipment and heating power supply thereof

Abstract

Ribbed steel bar short-circuit heat treatment equipment and a heating power supply thereof belong to the field of steel bar manufacturing. The reinforcing steel bar short-circuit heat treatment equipment comprises a plurality of modules, each module comprises two sets of reinforcing steel bar guide rollers, the two sets of reinforcing steel bar guide rollers are connected with a positive electrode and a negative electrode of a heating power source respectively, each set of reinforcing steel bar guide rollers comprises an upper roller and a lower roller, and carbon brush drums are fixedly arranged on the peripheries of rotating shafts of the upper roller and the lower roller respectively. The heating power supply is respectively communicated with the upper roller and the lower roller through the carbon brushes, and the positive electrode of the heating power supply and the negative electrode of the heating power supply are short-circuited through the reinforcing steel bars and simultaneously heat the reinforcing steel bars. The method can reduce heat loss, reduce production energy consumption, shorten production process length, reduce production cost, improve product performance indexes and improve product market competitiveness.

Description

technical field [0001] The invention relates to a heat treatment device and a heating power source, in particular to a short-circuit heat treatment device for a ribbed steel bar and a heating power source, belonging to the field of steel bar manufacturing. Background technique [0002] Steel bars are an indispensable material in the construction field. In recent years, with the continuous development of infrastructure projects in high-tech fields such as high-speed railways, the demand for ribbed steel bars has also increased. The manufacture of rebar also presents new challenges, requiring lower manufacturing costs and higher product quality. [0003] The patent number is 200410013658.2 to provide a high-strength and low-relaxation cold-rolled ribbed and scored steel bar and its production method and special production line. process. [0004] The manufacturing method of cold-rolled ribbed steel bar, the production process of most manufacturers, is similar to the productio...

AI Technical Summary

Problems solved by technology

[0015] In view of the problems in the existing cold-rolled steel bar forming process, such as low heating conversion rate, high energy consumption, long process, serious heat loss, high consumption of spare parts and high cost, unstable product performance due to uneven heating, and difficulty in improving product performance by first cold rolling and then heating, this paper The invention provides a ribbed steel bar short-circuit heat treatment equipment and its heating power supply, the purpose of which is to reduce heat loss, reduce production energy consumption, shorten the length of the production process, reduce production costs, improve product performance indicators, and improve product market competitiveness
