Nowadays, hot -dip galvanized steel pipes are common types of fire management, and they have fully exerted irreplaceable effects in the fire safety industry. Why can't the hot -dip galvanized pipe be replaced by cheaper welded pipes or cold galvanized pipes?
The thermal galvanized creation was invented in the mid -18th century. It was made of the development trend of thermal electroplating tinage processing process. To this day, hot -dip galvanized is still one of the extensive and effective processing processes in steel corrosion.
5. The operator of the operating table shall be manually adjusted to prevent the stuck pipeline according to the operation of the equipment in front of the furnace and the gesture command.
6. Pre -warm -up before use tools before furnace to prevent zinc splash from hurting people; frequently check whether the steel pipe is dropped into the pot, and it should be cleared in time; adjust the device in time Safety.
7. When adding zinc to the zinc pot, preheat zinc ingot first. When adding zinc, a bundle of zinc is never allowed. The zinc is not more than five pieces each time. Slowly plan, so as not to impact the damage to the zinc pot and splash a large amount of zinc injury; the iron material is strictly prohibited from falling in in the zinc solution to prevent a large amount of zinc residue.
8. When fusion zinc, it should be heated slowly. Do not burn the fire, otherwise there will be a life of a galvanized pot, and a large amount of zinc steam will volatilize. After this harmful gas is inhaled by the human body, it will suffer from a "casting fever" condition. In the process of melting zinc, once zinc has a higher temperature, you must not use your hand to mobilize zinc blocks to avoid burns. Appropriate tools should be used to mobilize it.
9. Clear zinc ash on the surface of the zinc liquid regularly. When scraping the ash, you should gently scrape the ash surface on the surface of the zinc liquid. Do not stir too much, so as not to raise the zinc ash. There is a personal accident or equipment accident.
10. Zinc blocks, crushed zinc, zinc, and steel pipes flowing from the ground in front of the furnace, zinc, and steel pipes flowing to the outside should be recovered at any time to reduce the heat loss of the zinc pot.
11. When adding aluminum ingots on the surface of the zinc liquid, it is necessary to ensure that the aluminum content of the zinc liquid surface is uniform.
12. In order to facilitate the residue and zinc pump, 20 tons of lead should be placed inside the zinc pot.
13. When fishing, the residue machine should be pre -heated first. The zinc residue should be stored in size. The temperature of the residue should be controlled above 455 ° C. When swinging the residue scratch machine, you must use a special tool to leave the zinc pot. The feet should be stood into a diced shape.
14. The heat -dip galvanized process is relatively strict. Therefore, in the process of hot -dip galvanized production, it is necessary to do a workshop, which means that the more roots or tonnage in the unit time, the lower the cost, and the higher the cost, the higher the cost.
