Previous experience and application of modern instrumental analysis to identify the accident laws dealing with accidents, combined with BOF steelmaking process conditions, proposed treatment and preventive measures. Following is a question about the BOF: (1) BOF: is molten iron, scrap steel, iron alloy as the main raw material, without the aid of external energy, by itself, the physical hot liquid iron and liquid iron heat chemical reaction between components in the converter steelmaking process completed. Converter is divided into acidic and alkaline by refractory, gas blown into the furnace at the site of a top blowing, bottom blowing and side-blown; by gas type for the sub-air converter and oxygen converter. Basic oxygen top blowing and top and bottom blowing converter because of its production speed, large output, a single furnace, high yield, low cost, less investment, as currently the most common steel-making equipment. Converter is mainly used for production of carbon steel, alloy steel and copper and nickel smelting. (2) BOF gas explosion: refers to the heated gas in a short period of time, the rapid expansion of volume in a very short period of time the release of large amounts of energy and explosion (3) outside the BOF steel spill: refe
