Causes And Preventive Measures Of Sintering Machine Furnace Bar Damage

Sinter is an important raw material of ironmaking blast furnace. The quality of sinter directly affects the output and consumption of ironmaking. Sintering production is also a key link in the process of metallurgical production, sintering machine is an important equipment for sinter production, and furnace bar is the most easily damaged part in the conveyor.

The furnace is arranged on the sintering machine trolley, the heat insulation sleeve is installed between them, and there is a certain activity gap. There is also a certain gap space between the furnace bar and each other. The trolley furnace bar is laid with a layer of bottom material (the granularity of the finished sinter is 10-20mm, the thickness is 20-40mm, different factories), and then a layer of the mixture to be sintered. In the running of the trolley, it enters the ignition furnace and starts the ignition. With the help of the fan, the mixture is sintered downward from the material surface. Under the action of a series of physical and chemical reactions and heat absorption and exothermic action, the temperature reaches about 200-950 degrees Celsius. Due to the harsh contact environment between the furnace and the material, the alternating effect of heating and cooling for a long time and the pressure wear of loading and unloading, the furnace can not be used for a certain period of time, and the ablation deformation must be replaced with the wear. There is also a damage caused by many aspects of the furnace bar paste can not be used normally must be replaced.
