hardox 500 specification resources appear to be in short supply

HARDOX 500 specification, Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.

The effect of elements in HARDOX 500 specification, wear-resistant steel plate on high-temperature temper embrittlement can be divided into: (1) Impurity elements such as phosphorus, tin, antimony and so on that cause the high-temperature temper brittleness of the wear-resistant steel plate. (2) Alloy elements that promote or slow down the brittleness of high temperature tempering in different forms and degrees. Chromium, manganese, nickel, silicon, etc. play a promoting role, while molybdenum, tungsten, titanium, etc. play a retarding role. Carbon also plays a catalytic role.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the HARDOX 500 specification plate should be derusted before cutting.

In order to further promote the ultra-low emission process and the technological innovation of flue gas treatment technology in China's steel industry, the China Institute of Metals and Beijing China-Japan Energy Conservation and Environmental Protection Engineering Technology Co., Ltd. (hereinafter referred to as Beijing China-Japan Alliance) will carry out technical cooperation to promote the activated coke dry process The application of desulfurization and denitrification technology in iron and steel enterprises, the signing ceremony of technical cooperation between the two parties was successfully held recently at the Chinese Institute of Metals.
