Ⅰ前言我厂热镀锌从前一直是用煤加热,此种加热方式有很多缺点。例如:煤质的好坏影响产量和质量,加热不均匀而且容易烧坏锌锅,平均每周用坏一只锌锅,致使镀锌锅消耗量很大,操作工人劳动强度大,周围环境污染严重,工艺不易控制等。为了改善上述状况,我厂新设计了一台热镀锌电阻炉。新电阻炉,具有结构简单、体积小、重量轻、易于更换、温度可自控、并能自
Ⅰ Preface My factory hot-dip galvanizing has been heated with coal in the past, this heating method has many shortcomings. For example: the quality of coal production and quality of the impact of uneven heating and easy to burn out the zinc pot, with an average weekly bad one zinc pot, resulting in a large consumption of galvanized pots, operating labor intensive, the surrounding environmental pollution Serious, difficult to control the process. In order to improve the above conditions, I plant a new design of a galvanized resistance furnace. New resistance furnace, with a simple structure, small size, light weight, easy to replace, the temperature can be controlled, and can from
