The test results of 650 semi continuous casting machine equipped with nitrogen protection device are analyzed, which provides evidence for the study of the relationship between nitrogen content and slab surface quality and oxygen content. Take samples from the middle part of the cast red copper ingot. First, remove...
In order to test the application effect of the nitrogen protection device, the power frequency induction furnace is selected as the test equipment. The smelting furnace with horizontal structure can effectively control the tilting process of the converter and discharge slag without side. Combined with the closed chute with...
The device is connected with the furnace head through the flange head, and uses the sleeve and the protective cover to form a nitrogen protection space structure. The nitrogen is sent into the protection device from the air inlet, which can prevent the casting pipe from being directly exposed...
