As a bright tube manufacturer, the raw material selected for the production of embossing tubes by Zoomian Stainless Steel has always been the steel strip of the refining furnace. Customers often ask: What is the difference between your raw materials and other manufacturers? Today, I will introduce it to you.

Bright tube raw materials have the difference between refining furnace and intermediate frequency furnace.

1. Raw materials of refining furnace:

Refining furnaceembossing tubeIt is refined from ore and other materials with fine furnace coal. It has ideal control over harmful raw materials, good polishing, soft material and smooth welding seam. It mainly has strong corrosion resistance, good technology, convenient deep processing, bending pipe and welding.

Refining furnace for raw ore smelting, commonly known as AOD refining furnace is in the standard atmospheric pressure to the molten steel blowing oxygen at the same time, blowing inert gas (Ar,N2), by reducing the CO partial pressure, to achieve the effect of false vacuum, forcing the carbon content down to a very low level, but also inhibit the oxidation of chromium in steel.

It is suitable for the production of low-carbon and ultra-low-carbon stainless steel, and it is easy to control the S content in special steel below 0.005%. AOD refining furnace can carry out secondary steelmaking, so that relevant elements can be flexibly added or reduced in order to achieve the purpose of refining. Scrap iron and iron sand are generally used for steelmaking in the smelting process. Product quality is relatively high, good ductility, stainless steel plate to do deep drawing products are generally used refining furnace smelting.

2. Intermediate frequency furnace

The steel strip of the stainless steel decorative tube of the medium frequency furnace is relatively poor in both material and process, and the composition control is not well grasped, which will also pollute the environment. In addition, the polishing effect is not good, the hardness processing is difficult, and the main performance is unstable and the corrosion resistance is poor. The stainless steel decorative tube produced by the medium frequency furnace is unstable and easy to rust, and the material stability of the refining furnace is not easy to rust.

Medium frequency furnace material instability is also easy to rust, refining furnace material stability is not easy to rust. Differentiation of elements: the carbon content of intermediate frequency furnace is more than 0.1, and the carbon content of refining furnace is less than 0.1.
