Problems solved by technology

[0005] The disadvantage of this method is that a large amount of lead needs to be used. The heat-treated lead pot usually contains dozens of tons of lead liquid. The lead liquid at high temperature is volatile, and the reaction of lead liquid and oxygen also produces a large amount of lead oxide (lead soil), which is easy to Cause heavy metal lead pollution, operators breathe in the air with lead dust, contact with metal lead and lead soil to absorb lead, prone to lead poisoning
Therefore, the lead bath quenching technology causes heavy gold pollution to the environment and is harmful to human health. The country has strictly limited the amount of lead used in industry to reduce environmental pollution

Abstract

The invention discloses a solution for treating the steel core for aluminum-coated steel through water bath heating and a method for treating the steel core for aluminum-coated steel through water bath heating. The solution for treating the steel core for aluminum-coated steel through water bath heating is a sodium polyacrylate aqueous solution with the concentration of 10% to 25%, and the temperature of the sodium polyacrylate aqueous solution is controlled to range from 85 DEG C to 95 DEG C. The method for treating the steel core for aluminum-coated steel through water bath heating comprises the following steps of (1) sending the steel core for aluminum-coated steel into a heating furnace to be heated till the temperature of the steel core ranges from 900 DEG C to 1200 DEG C, (2) directly conveying the heated steel core for aluminum-coated steel into the sodium polyacrylate aqueous solution with the temperature of 85 DEG C to 95 DEG C and the concentration of 10% to 25% for sorbitizing treatment. According to the solution for treating the steel core for aluminum-coated steel through water bath heating and the method for treating the steel core for aluminum-coated steel through water bath heating, sorbitizing of the steel core is realized in the sodium polyacrylate aqueous solution, the method has the advantages that the reaction effect is good, the efficiency is high, and no hazardous substances will be generated, and the method is an economic, high-efficiency and environment-friendly treatment technology, and can be widely applied to the field of sorbite treatment of steel cores.

Description

technical field [0001] The invention relates to the field of aluminum-clad steel processing, in particular to a cooling treatment process for sorbitizing a steel core for aluminum-clad steel. Background technique [0002] Aluminum-clad steel wire is a high-efficiency bimetal composite material for electric power. It is made of a round steel wire that is evenly and continuously tightly coated with a layer of high-purity aluminum. This material has both the good conductivity of aluminum and the high strength performance. The basic manufacturing process is as follows: high-carbon steel wire rod is pre-drawn into a steel core with a certain diameter according to its cold working performance, and then the steel core is subjected to sorbite isothermal heat treatment, and the heat-treated steel core is continuously extruded and packaged. Cover a certain thickness of aluminum layer to form an aluminum-clad steel busbar. The aluminum-clad steel busbar is properly drawn and cold-work...
