Product Description:

Hot-dip Zinc Coating Steel Building Roof Walls

1.Structure of Hot-Dip Galvanized Steel Sheet Description:

Hot-dip galvanized steel coils are available with a pure zinc coating through the hot-dip galvanizing process. It offers the economy, strength and formability of steel combined with the corrosion resistance of zinc. The hot-dip process is the process by which steel gets coated in layers of zinc to protect against rust. It is especially useful for countless outdoor and industrial applications. Production of cold formed corrugated sheets and profiles for roofing, cladding, decking, tiles, sandwich walls, rainwater protective systems, air conditioning duct as well as electrical appliances and engineering.

 

2.Main Features of the Hot-Dip Galvanized Steel Sheet:

• Excellent process capability

• Smooth and flat surface

• Workability, durability

• Excellent anticorrosive property

• High strength

Q:What’s the difference between natural cooling and slice cooling?
Cooling with furnace means after thermal insulation, stop heating furnace and make the parts in the furnace cool slowly to the room temperature with the furnace. Natural cooling is a kind of cooling method utilizing fluid circulation based on the fact that density varies with temperature to remove hea
Q:What are the production processes of aluminum coil and what are the functions of various industrial furnaces in the production of aluminum? The more detailed, the better. Thank you! Points!
There are aluminum annealing furnace, aluminum alloy quenching furnace, aging furnace and smelting furnace.
Q:Which companies will use aluminum sheet and coil?
Plants to make auto parts such as exhaust pipe thermal baffle, muffler thermal baffle and front thermal baffle.
Q:What kind of sensor is appropriate for aluminum coil thickness measurement?
Use two sensors of ZLDS10X series to make a thickness gauge
Q:How to calculate the wall thickness with the gross weight of aluminum coil known?
Gross weight*density=volume volume÷(aluminum sheet *width)=thickness
Q:How heavy and long is the aluminum rolling on average?
On average it is 5 or 6 tons, and you can weigh specific ones. The length = weight/(width*thickness*density).
Q:Why does the end face of aluminum coil have grease spots?
The reason may be that the manufacturer hasn’t cleaned. Before being coated, the aluminum should be cleaned carefully. Otherwise the paint will peel off.
Q:What does it mean to slice aluminum coil by decoiler machine?
The operating procedures of decoiler machine: 1, Select appropriate aluminum coil according to production work order requirement to be processed, paying attention to the thickness, width and material of aluminum coil. 2, Put the aluminum coil into the coil loading car with traveling crane and inch the car into the uncoiler. The aluminum coil and decoiler machine should be in the same direction. Hold the aluminum coil down with leading head, and open the auxiliary bearing. 3, Turn on the shovel head, and inch the uncoiler to lead the aluminum sheet into the leveler. Adjust the leveler according to the thickness and width of aluminum sheet to ensure the flatness. 4, Turn on the front gap bridge and back gap bridge in control main platform, inch the leveler to lead aluminum sheet into re-leveler. Adjust the re-leveler to ensure the flatness of aluminum sheet. Put it into the shear gauge and plate shearer. 5, Take back the front and back gap bridge. Inch the plate shearer to cut off the sheet head and shear the aluminum sheet according to production work order. Check the first sheet to see whether it meets the quality standard and whether there is defect in flatness, length, diagonal, and surface of aluminum sheet. If it is qualified, turn on the conveyor. Put the aluminum sheet holder on the pallet. Adjust the pallet according to the width and length of aluminum sheet. Input quantity and length on the control main platform. Then turn on the auto control to produce automatically. The production process can be observed at any time. 6, If there is aluminum coil left, unwind, package and put it into storage in reverse steps.
Q:What is the formula to calculate the wall thickness of aluminum coil?
Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
Q:How does aluminum ingot be processed to aluminum coil (aluminum sheet)?
First it should be made into blank and then put on the rolling mill.
