Stainless steel decorative tube of raw materials where is the difference?

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

Stainless Steel Decorative TubeRaw materials have the difference between refining furnace and intermediate frequency furnace

1. Raw materials of refining furnace:

The steel strip of the stainless steel decorative tube of the refining furnace is made of ore and other materials and refined furnace coal. The control of harmful raw materials is ideal. The material is soft, polished and the weld seam is smooth. The key is strong corrosion resistance, deep processing, good technology, convenient deep processing such as bending 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, so that the carbon content down to a very low level, and 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 poor in both material and production process, the composition control is not very good, and the environmental damage is also very serious. In addition, the polishing effect is poor, the hardness is high, and the deep processing is difficult, and the important thing is that the performance is unstable and the corrosion resistance is poor. Intermediate frequency furnace is unstable and easy to rust, refining furnace material stability is not easy to rust. One: intermediate frequency for scrap metal smelting, the use of alternating current to generate alternating magnetic field, in the alternating magnetic field inside the metal is generated alternating induced potential and induced current, and the direction of the induced current and furnace induction coil in the opposite direction.

Under the action of induced electromotive force, the heated metal generates an induced current. When the stainless steel plate passes through the current, it generates heat to overcome the resistance of the metal. The medium frequency furnace uses this heat to heat and melt the metal, so as to achieve the purpose of melting. The medium frequency furnace can only make steel once, especially in the raw materials can not be flexibly controlled. Therefore, stainless steel plate smelting when the general use of stainless steel scrap and iron sand smelting. This smelting method can not control the content of certain elements, so the product quality is relatively slightly inferior, generally will not be used for deep processing and other products industry.

The material of the intermediate frequency furnace is unstable and easy to rust, and the material of the refining furnace is stable and not easy to rust. 04: Element distinction: the carbon content of the intermediate frequency furnace is more than C 0.1, and the carbon content of the refining furnace is less than 0.1.

The above is the difference between the stainless steel decorative pipe raw material steel belt, I hope it can be helpful to everyone.
