Problems solved by technology

In order to prevent the capillary from being oxidized, the existing domestic continuous pipe mills use the method of blowing nitrogen and borax into the capillary or using borax antioxidants from foreign companies. Due to the simple formula of borax antioxidants, the use performance and comprehensive technology of the product are not considered. performance, resulting in agglomeration of the product in actual production and application, clogged nozzle, poor oxidation resistance and lubrication effect, resulting in abnormal production, steel pipe product quality, production efficiency, and economic benefits are greatly affected

Abstract

The invention relates to a borax antioxidant. The borax antioxidant comprises the following components in weight percentage: 20 to 40% of powdery anhydrous borax, 15 to 30% of anhydrous sodium sulfate, 10 to 30% of sodium aluminate, 5 to 10% of MgO and 5 to 10% of dispersing agent. A preparation method of the borax antioxidant comprises the following steps: adding the powdery anhydrous borax into a reaction kettle at room temperature; stirring; adding the anhydrous sodium sulfate and the sodium aluminate; after stirring for about five minutes, adding the MgO and the dispersing agent; and stirring for about twenty minutes later, and stopping stirring. The borax antioxidant is suitable for rolling different materials and has the characteristics of no pollution, strong oxidation resistance and good chemical stability and physical stability.

Description

technical field [0001] The invention relates to a borax antioxidant and a preparation method thereof Background technique [0002] During the continuous (hot rolling) pipe rolling unit rolling seamless steel pipes at high temperature, the inner wall of the capillary tube will be oxidized after piercing and rolling, and the generated oxide scale will cause deep scratches on the inner wall of the steel pipe. In order to prevent the capillary from being oxidized, the existing domestic continuous pipe mills use the method of blowing nitrogen and borax into the capillary or using borax antioxidants from foreign companies. Due to the simple formula of borax antioxidants, the performance and comprehensive technology of the product are not considered. performance, resulting in the actual production and application of the product often agglomerated, clogging the nozzle, poor oxidation resistance and lubrication effect, resulting in abnormal production, steel pipe product quality, pro...
