A new induction heating device for a micro-tension reducer was added. Heating before Zhang reduces; heating method: electric induction heating; ensure that the capillary heating temperature range is between 750~900℃. Furnace purpose: used for heating before 20-frame micro-tension reducer. The capillary tube is sent to the heating furnace by the conveying roller, and after the heating temperature is qualified, it is sent to the sizing machine by the conveying roller.
Maximum allowable heating temperature: 950℃;
Temperature uniformity: ±20℃;
Capillary speed: the speed of steel passing through the supporting tension reduction machine
