Embodiment 1

[0059] 1. Processing of anti-corrosion and anti-magnetic steel: Add steel scrap and pig iron into the melting furnace to heat up and melt. The melting furnace should be an intermediate frequency induction furnace. The melting temperature is generally around 1450°C-1550°C. Add nickel plate, ferromanganese, ferrochromium, ferromolybdenum, ferrovanadium and ferroniobium in sequence, and the diameter of the material block is preferably 50-80mm. The mass percentages of the above chemical components are controlled as follows: C: 0.25%, Si: 0.70%, Mn: 0.50%, Cr: 17.00%, Ni: 11.00%, Mo: 2.00%, V: 0.45%, Nb: 0.10%. After melting, when the furnace temperature reaches 1550-1580°C, deoxidize, dehydrogenate, and denitrify. The deoxidizer is made of aluminum wire and Si-Ca alloy. -5mm is appropriate) Ti:0.13%, the metal liquid surface is covered with a covering agent at this time, and the outside air is cut off, the rare earth ferrosilicon alloy is added to the ladle (the diameter is prefer...

Description

Technical field [0001] The present invention belongs to the field of alloy materials, and especially involves marine petroleum exploration materials, especially the marine oil exploration of marine corrosion and anti -magnetic steel. Background technique [0002] At present, the drums such as ZG3MN19CR4 non -magnetic steel without magnetic steel smelting and processing technology have matured in China.However, the strength and abrasion resistance of this material cannot meet the requirements of the use during use, especially when working in the marine environment, its ability to resist corrosion is significantly insufficient, which not only affects the appearance quality of the drum, but also greatly affects the drums of the drum.The service life leads to an increase in the frequency of the roller of the well test. Invention content [0003] The purpose of the present invention is to propose a new non -magnetic steel that is neither magnetic, anti -ocean corrosion, and high stre...
