Brief introduction of Chengdu 304 stainless steel pipe
Brief introduction of Chengdu 304 stainless steel pipe
Release time: November 30, 2020
Chengdu 304 stainless steel pipe, 304 stainless steel pipe in the air or chemical corrosion medium can resist corrosion of a kind of high alloy steel, 304 stainless steel pipe has beautiful surface and good corrosion resistance, does not need to go through the surface treatment such as color plating, but play the inherent surface properties of stainless steel, used in many kinds of steel.
What are the advantages of BOF steelmaking
What are the advantages of BOF steelmaking
Release time: November 24, 2020
The first advantage of oxygen top blown converter steelmaking is fast production speed: a 300 ton oxygen top blown converter blowing: Valve less than 20 minutes, bag auxiliary time generally not more than an hour. It takes about seven hours for a 300 ton open hearth furnace to make one furnace of steel. Secondly, there are many varieties: oxygen top blown converter can not only make ordinary steel, but also some ordinary low alloy steel. Almost all kinds of steel can be made in open hearth furnace. Due to pure oxygen blowing, the content of harmful gases such as nitrogen and hydrogen in the steel is relatively high, which improves the quality of steel

How to control the quality of high grade silicon steel casting billet
Release time: November 17, 2020
Where is Chongqing stainless steel pipe wholesale market? Wuhan Iron and steel works is a stainless steel pipe manufacturer which produces high grade silicon steel with good quality and large output (annual output of 100000) and a world-class new process flow. Silicon steel is divided into non oriented and oriented. The non oriented silicon steel is rolled in the same direction, which is mainly used for motor. The grain orientation is obtained during the treatment of silicon steel sheet, which is mainly used as silicon steel sheet for transformer.

How to identify the difference between scrap and scrap iron
How to identify the difference between scrap and scrap iron
Release time: October 21, 2020
Chengdu stainless steel special-shaped pipe: the identification of waste steel using chemical analysis and spectral analysis is more accurate rhyme. At present, these two methods are mostly used in iron and steel enterprises and mechanical processing departments to test and distinguish the chemical composition of various steel materials and products. Special equipment and instruments and skilled operators are needed. At present, due to the limited conditions of metal recovery departments, it is rarely used in the identification of scrap iron and steel, and most of them are based on work experience, using simple and easy sensory identification and spark identification methods
Activation method and principle of electroless nickel plating on stainless steel cathode
Principle of cathode activation and chemical activation for pre nickel plating of stainless steel tube
Release time: October 13, 2020
In order to avoid iron, chromium and other metal elements from dissolving into the pre nickel plating tank and causing the instability of the pre nickel plating tank, the anode electrolytic activation was changed to the cathode electrolytic activation, which was set up separately from the pre nickel plating bath. The hydrogen generated from the cathode was used to reduce and destroy the surface oxide film to purify the surface. After the cathode electrolysis activation, the stainless steel is transferred into the pre nickel plating bath immediately without washing, which also achieves good results. However, the time required for transfer should be as short as possible.

Chengdu Iron and steel market: significance of waste steel recycling on environmental protection
Release time: September 23, 2020
Chengdu Iron and steel market: the iron and steel industry is an important part of the national economy. The amount of steel output of a country indicates the progress and backwardness of the country's industrial level. The recovery and utilization of scrap iron and steel is closely related to the development of iron and steel industry, and it increases with the increase of steel output. The main raw materials of steelmaking are pig iron and scrap steel. In order to save ore and energy and reduce production cost in developed capitalist countries, the utilization of scrap iron and steel resources is emphasized in iron and steel production. With the rapid development of national economy, China's waste iron and steel recycling work is also growing
