Baking method of alloy furnace

  The so-called oven is an operation in which the furnace lining and electrodes are gradually adapted to the feeding and smelting by heating, and its main purpose is to dry the furnace lining and roast the electrode paste. The quality of the oven will not only affect the service life of the furnace lining, but also directly affect whether the electric furnace can be put into production smoothly. Therefore, the furnace system should be formulated in detail in the furnace opening plan and strictly implemented. Ovens are divided into coke ovens and charcoal ovens.

  Coke oven

  Coke baking, as the name suggests, is a method of using the combustion heat of coke to oven. Large metallurgical coke with less ash content should be used to make fuel (particle size> 150 mm), and the coke should be close to the electrode during the baking of the electrode paste. Combustion, add in time, in order to help coke combustion, you can use air blowing to support combustion. No matter which oven method is used, the purpose is to bake the electrode paste, so that the electrode has a certain ability to withstand current, and prepares for the next electric oven. Therefore, the sintered state of the electrode and the height of the electrode paste should be frequently observed to determine whether the conditions of the electric oven are available in time. In the previous process, the coke oven time is longer (10000KVA electric furnace 72-96 hours). In production, according to The actual situation can be appropriately shortened, thereby reducing the waste of coke.

  Electric oven

  The purpose of the electric oven is the same as that of the coke oven, and its main purpose is still to increase the furnace temperature and roast the electrodes so that the electric furnace has the conditions for positive production. The power of the electric oven is determined by the capacity of the electric oven and the material of the furnace lining. A low-voltage oven should be used for the electric oven to try to ensure the stability of the arc and less moving electrodes to keep the load of the three-phase electrodes uniform. It should be strictly implemented in accordance with the power supply system of the electric oven.

  The electric oven determines the speed of the electric furnace temperature increase, the electrode sintering speed and the sintering quality, so the power supply system should be scientifically based on the characteristics of the electrode sintering.
