Embodiment 1

[0017] An iron alloy containing Sc and Ti for hot-dip galvanized anti-vibration iron pan at 360-450 degrees. In terms of weight percentage, the chemical composition of the alloy is: Ca:0.2wt.%, Sb:0.5wt.%, Ge:0.4wt.%, Sc:0.2wt.%, Ti:0.2wt.%, Mo:0.4wt .%, the balance is iron. Alloy preparation method: Add the above-mentioned raw materials into an argon-protected induction furnace, and use a silicon carbide crucible; induction heating to 1500-1600 degrees to form an alloy solution, and use the electromagnetic stirring effect to fully stir for about 10 minutes; The alloy liquid is kept at 1500-1600 degrees for 10 minutes and then cast into the required round ingot. The obtained ingot is hot-rolled at 800 degrees, and the rolling reduction in each pass is 10-15%. After every two hot rollings, the intermediate annealing temperature is 900 degrees, and the temperature is kept for 1 hour. Finally, the material is rolled into a steel plate with a thickness of 40-60mm, and the iron ...

Abstract

The invention discloses an Sc and Ti containing iron alloy for a hot-dip galvanizing vibration-proof iron pan and a processing technology thereof. The alloy is prepared from the following components in percentage by weight: 0.2 to 0.4 percent of Ca, 0.5 to 0.8 percent of Sb, 0.4 to 0.6 percent of Ge, 0.2 to 0.5 percent of Sc, 0.2 to 0.3 percent of Ti, 0.4 to 0.5 percent of Mo, and the balance of iron. According to the hot-dip galvanizing iron crucible made by steel plates prepared by casting and hot-rolling the material, the vibration and dropping prevention ability of a transitional layer ofzinc liquid can be greatly improved, the service life of the iron pan is prolonged to 20 years or above from 7 to 10 years, and the alloy has the effects of improving the production efficiency and reducing the cost.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to an iron alloy. Background technique [0002] Hot dip galvanizing is called hot galvanizing for short. Hot-dip plating is a process in which the workpiece to be plated is immersed in a molten metal liquid to form a metal coating on the surface. Specifically, the iron and steel material to be plated is immersed in the molten coating metal and then taken out and cooled to form a metal coating on the surface. It is widely used in the production of low-melting point metal zinc, tin, aluminum, lead and their alloy coatings, mainly to prevent corrosion For the purpose, and has a certain decorative effect. The most widely used hot-dip coating is hot-dip galvanizing. When steel materials are exposed to corrosive conditions such as air, soil, and water, hot-dip galvanizing is the most widely used, effective and economical means of protection, such as steel structures for factories, trans...
