The invention provides a method for prevention of nitrogen increase in molten steel during steel tapping from a converter, which comprises the steps of controlling the argon blowing time and argon flow before and during steel tapping from the converter, and blowing argon to the steel ladle in two segments or uninterruptedly till the finish of steel tapping. Thereafter, air in the steel ladle can be evacuated by the argon blown in to prevent the molten steel in the ladle contacting with air while tapping and to keep the molten steel in the ladle under the protection of argon all the time, which not only prevents molten steel contacting with air to cause nitrogen increase, but also removes the nitrogen [N] that can easily adsorb on the surface of the bubbles from the molten steel with the float and discharge of nitrogen bubbles. The method of the invention is simple and easy to implement and operate, and can remarkably reduce the possibility of nitrogen increase in the molten steel during tapping, so that the nitrogen increase in the molten steel can be controlled below 3ppm after tapping.

The invention provides a range hood with an auxiliary air inlet channel. An oil filtering plate is installed on the front face of a cooking fume collecting cover. Main air inlets are formed in the oil filtering plate, and the oil filtering plate of the range hood is obliquely arranged towards the rear lower side from top to bottom. Auxiliary air inlets are formed in at least one of an area adjacent to the upper side edge of the oil filtering plate and an area adjacent to the lower side edge of the oil filtering plate. The auxiliary air inlets are in a long bar shape and are transversely through. Due to the fact that the auxiliary air inlets of the range hood are continuous and uninterrupted air inlet channels, the defect that gate-hole-shaped main air inlets are interrupted and not continuous can be overcome, and the air inlet area can be enlarged and a cooking fume path can be changed through the auxiliary air inlets. In addition, the included angle alpha between the oil filtering plate and the horizontal plane is designed to be larger than or equal to 18 degrees and smaller than or equal to 30 degrees, and under the condition that negative-pressure covering angles are the same, the negative-pressure covering area of a cooking bench is larger; and furthermore, after the auxiliary air inlets are arranged, the phenomenon that negative pressure is weakened and cooking fume escapes due to the fact that the inclination angle of a cooking fume guide plate relative to the horizontal plane becomes smaller can be effectively avoided, and therefore the cooking fume absorbing effect is improved.
