Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel billet anti-oxidation, in particular to an online spraying device for steel billet anti-oxidation coating. Background Art
[0002] Before rolling, the billet must be heated and soaked in a heating furnace in an oxidizing atmosphere. Depending on the capacity and process of each rolling mill, the temperature of the billet in the heating furnace is above 1000°C, and the heating time is generally 2 to 3 hours or even longer. The surface of the billet reacts violently with the oxygen in the furnace at high temperature to generate a large amount of oxide scale, which significantly reduces the yield rate of steel. Sometimes, due to rolling failures or equipment failures, the heating furnace process is not adjusted in time, which will further aggravate the generation of oxide scale in the furnace. According to incomplete statistics, in the production of the metallurgical industry, on average, the oxidation and burning loss caused by high-temperature oxidation in the furnace is 0.5%-2.5% per heating. Therefore, the oxide scale generated by high-temperature oxidation causes direct production losses to steel companies. At the same time, if the generated oxide scale is not cleaned before rolling, it is easy to press into the surface of the steel during the rolling process, forming an oxide scale press-in defect. Although it can be repaired by grinding and welding, it affects the appearance of the product. Severe cases directly lead to product scrapping, causing serious economic losses. Utility Model Content
