Embodiment 1
[0026] Example 1 evaluates the spalling resistance of refractory materials A and B; among them, refractory materials A and B are aluminum-carbon, but are provided by different manufacturers. During use, except for the refractory materials, other process parameters and conditions are the same .
[0027] The specific detection methods are as follows:
[0028] The test steel type is 87Mn, and its chemical composition is shown in Table 1. The steelmaking and rolling process can adopt the common cord steel production process in this field, namely "converter / electric furnace-LF refining-continuous casting-rolling-wire rod drawing -Fracture inspection and analysis", as follows:
[0029] ①Converter process: the end of the converter adopts the high carbon drawing process, and the converter steel tapping process adds appropriate amount of metal manganese, low titanium low aluminum silicon ferrosilicon and recarburizer, and takes samples to quickly analyze the composition of the molten steel. ...
