Process and advantages and disadvantages of Corten steel plate

Weather resistant steel plate manufacturing technology

Weather-resistant steel plates generally adopt the process lines of fine feed into the furnace - smelting (converter, electric furnace - micro-alloying treatment - argon blowing -LF refining - low superheat continuous casting (feeding rare earth wire)- controlled rolling and controlled cooling. During the smelting process, the scrap steel is added to the furnace with the charge and smelted according to the conventional process. After the steel is produced, the deoxidizer and alloy are added. The molten steel is treated by argon blowing and then cast immediately. Due to the addition of rare earth elements in the steel, the weather-resistant steel plate is purified and the content of inclusions is greatly reduced

Use of weathering steel

Weathering steel is mainly used in railway, vehicle, bridge, tower, photovoltaic, high-speed engineering and other long-term exposure to the atmosphere of the use of steel structures. It can also be used in the manufacture of containers, railway vehicles, oil derricks, harbor buildings, oil platforms and containers of sulfur-containing corrosive media in chemical and petroleum equipment. In addition, due to the unique appearance of weathering steel, it is also often used in public art, outdoor sculpture and building exterior wall decoration.

advantage

Green and environmental protection

No need for initial painting, can reduce the use of fireproof coating and fireproof coating, thereby reducing pollution, shorten the construction period, reduce costs and reduce maintenance, is a "green", sustainable development of economic steel;

2. High visual performance

The weather-resistant steel plate will change with time, and its color brightness and saturation are higher than that of general construction materials, so it is easier to highlight in the background of garden greening;

3. Strong body shaping ability

The weather-resistant steel plate is easier to shape into a rich and varied shape, and can maintain excellent integrity;

4. Good spatial definition

The use of very thin weather-resistant steel plates to clearly and accurately separate the space, making the site concise and bright.

Cons:

Corrosion of welding points

The oxidation rate of the welding point must be the same as that of other materials, which requires special welding materials and technology;

2. Water corrosion

Weathering steel plate is not stainless steel plate, if there is water in the concave position of weathering steel, the corrosion rate will be faster, so it must be drained;

3. Salt-rich air environment

Weather-resistant steel plate is more sensitive to salt-rich air environment, in such an environment, the surface protective film may not prevent the internal further oxidation;

4. Fading

The rust layer on the surface of the weathering steel plate can make the surface of the object near it become rusty;

5. Maintenance

Need to deal with rust and a variety of patterns and colors, there are many processing prices are relatively expensive.
