Energy-saving and environment-friendly production method for hot galvanized steel wires

The invention discloses an energy-saving and environment-friendly production method for a hot galvanized steel wire. The method comprises the following steps: steel wire paying-off straightening, heating and straightening, ultrasonic cleaning, gravel washing, ultrasonic alkali washing, electrolytic alkali washing, hot water washing, assistant plating and drying, hot galvanizing, repeated water vapor cooling after nitrogen wiping, and taking-up. According to the production method, a pickling process in the prior art is eliminated, a special guide roller, a ceramic internal heating zinc pot andnitrogen wiping are adopted, waste gas is collected and treated on a production line, and the production method has the characteristics of being high in production efficiency, and is more energy-saving and environmentally friendly. 一种热镀锌钢丝节能环保的生产方法，该生产方法包括以下步骤：钢丝放线矫直、加热并矫直、超声波清洗、砂砾水洗、超声波碱洗以及电解碱洗、热水洗、助镀并烘干、热镀锌、氮气抹试后再多次水汽冷却、收线。该生产方法取消了现有技术中的酸洗工序，采用特殊导辊、陶瓷内加热锌锅、氮气抹试，并在生产线上进行废气收集处理，具有生产效率高，更加节能环保的特点。
