large deformation proportion remains high specification products
To break this bottleneck as soon as possible , last March , the company set up a special project team bearing the main research content is in large thin-walled bearing outer heat treatment deformation control . First, in the application of the device , the project team presented with a new furnace to replace the rollers mesh belt furnace . Since the former is heated by radiation , the temperature can be precisely controlled , better Crossed-roller-bearing heating uniformity , can greatly reduce the amount of deformation . Meanwhile, the roll bar with nitrogen and propane furnaces for protective atmosphere , allowing the product through appropriate oxidation to achieve the desired hardness , to meet different customer requirements.
Roller furnace new production line put into operation after a period of time , the question came up : the into the furnace to Compound baskets, large deformation proportion remains high specification products . The project team developed the implementation Tapered bearing plan of the project, the schedule lists : the first step small batch processing, such as the promotion of a wide range of process maturity and then , at the same time according to the time schedule, to reduce the amount of deformation also put forward a clear indicator. Through several experiments , on the one hand , optimizing layouts, eventually completely without baskets directly to the placed on the stove , so that a single into the furnace to increase the amount of productivity also will increase ; on the other hand , the project team by replacing the quenching oil, according to the product type stirrer speed and time settings , oil quenching is more evenly distributed in the surface, to ensure the hardness after quenching and qualified to achieve the required in order to better control the amount of deformation . After these improvements reflect subsequent grinding staff is very good . They say that good quality new processing technology ,
