During the production of bar rolling,the finished products occasionally have rolling scars and folding defects at a fixed position in batches.Due to the lower positioning of the defects in the rolling piece,it is not easy to dis-cover the defects during production,which often leads to product rejection in batch,high cost loss and high quality risk when the defects are found at the finish product inspection stage.The problem eliminates every time after the reheating furnace is maintained,but re-appears at set intervals and becomes a tough issue in production.On basis of the re-search on the heating system of the reheating furnace,the analysis on the combustion state of the burners and the test on the material of the cushion block,the nodulation problem of water beam cushion block for the reheating furnace is ex-plored systematically,many inspections inside the furnace are carried out in combination with the actual condition at the site,the solution and preventive measures are summarized for cushion block nodulation in the reheating furnace.After taking the measures accordingly,the nodulation problem is improved significantly with high promotional value.
