When it comes to annealed black wire, we should not be familiar with it. It is made of high quality iron wire. In the industrial field, it is widely used. Annealed black wire is an important characteristic of the elasticity and flexibility of the rod, it is dark color, zinc consumption metal, and the matrix metal formed into the layer, good corrosion resistance, hot dip galvanizing in the outdoor environment can last for decades. Annealed wire is a kind of metal wire used in construction, petroleum, chemical industry, aquaculture, garden protection, it can play a good role in strengthening and protection. Annealed wire is used in many places, it has a very popular type, galvanized wire that is black annealed wire. So what is the difference between black annealed wire and ordinary annealed wire?
Annealed black wire is softer than annealed wire, stronger flexibility, even softness, consistent color, annealed black wire has stronger oxidation resistance, the raw material of annealed black wire is generally drawn from the Q195 model wire wire. The selected raw materials are calcined at a high temperature of about 1000 ℃ for enough time, and then cooled at an appropriate rate. The purpose is to reduce the hardness, improve the machinability; Eliminate residual stress, stabilize size, reduce deformation and crack tendency, refine grain, adjust the structure, eliminate the defect of the structure, so that we can guarantee the quality of the use. It is a soft wire product made of low carbon steel cold drawing, heating, constant temperature, heat preservation and other processes.
Annealed black wire has the advantages of good application effect, wide application range, low production cost, wide use and scale, and better protection function. Therefore, it is an important material for steel parts in strict working environment. We should try our best to ensure its cleanliness, so that it can avoid rust, avoid its oxidation phenomenon. At present, annealed black wire plays a great role in the field of industry in China.
