Iron wire galvanizing heating and annealing equipment has a wide range of applications, especially in the industrial field. It is an important process equipment for galvanizing iron wire products. In order to ensure the smoothness of the iron wire, the requirements for this equipment are particularly high. The iron wire galvanizing heating annealing equipment produced by Kehua manufacturers happens to meet this point. Iron wire galvanizing heating and annealing equipment 1. How to anneal iron wire Galvanized iron wire is generally produced with No. 3 steel. The purpose of annealing is to remove work hardening and obtain a suitable metallographic structure of the steel. Generally, the heating temperature should be greater than 700 degrees, and the cooling effect with the furnace is the best. Preferably, higher temperature annealing can also be used before galvanizing. 2. Precautions for galvanizing heating and annealing of iron wire Generally, the iron wire after drawing is best to be processed within three days. If it cannot be achieved, it needs to automatically stop drawing for a short time; the annealed galvanized wire should be pickled and rust-proof before applying zinc. Treatment; only pickling and non-rust-proof iron wires should be zinc coated in the fastest time; pickling and rust-proof iron wires should be zinc-coated within 24 hours; the drawn iron wire has no oil on the surface after annealing, no annealing The galvanized iron wire is often filled with lubricating oil, so the annealed galvanized wire, the operator should keep his hands clean and oil-free during the zinc coating process, and it is best to wear clean overalls and gloves to work. The binding force of the zinc layer will be reduced when the oily iron wire is coated with zinc, and the zinc layer will easily fall off after the zinc is coated. Galvanized wire is mostly pickled with hydrochloric acid. The concentration of hydrochloric acid is 20% and the temperature is 30 degrees. The pickling solution can be accompanied by a certain corrosion inhibitor product. The pickling should not be excessive. Take it out within a certain time, and the concentration of pickling solution and pickling time should be controlled within the specified process. Excessive pickling will cause hydrogen embrittlement of galvanized wire, reduce corrosion resistance, and reduce brightness, so beware of excessive pickling. 3. Guangzhou Kehua Technology Co., Ltd., a manufacturer of iron wire galvanizing heating and annealing equipment, aims to 'produce energy-saving and environmentally friendly induction heating equipment to save money for usersIn March, we have developed and manufactured a full range of high-frequency induction heating equipment: medium-frequency Induction melting furnace
, ultra-sonic heating machine, ultra-high-frequency heating equipment and supporting medium-frequency diathermy forging furnaces, CNC quenching machine tools, chillers and related equipment. , Widely used in metal processing industry, such as metal preheating, high frequency welding (brazing), diathermy forming, quenching, annealing, thermal fusion and other processes, all products can be customized according to customer process requirements. Iron wire galvanizing heating and annealing equipment After the iron wire is annealed, it will be galvanized. After a set of processes, the appearance of the iron wire is very clean and the service life is relatively long. So what are the manufacturers of iron wire galvanizing heating annealing equipment? I think Kehua is a good manufacturer.
For business owners unsure of how to effectively incorporate new technology into our induction heating system, life may have just become a little easier.
