The invention discloses an IF steel and a smelting method, a smelting furnace and a smelting system thereof, and belongs to the technical field of metallurgy. The content of N of the IF steel is not higher than 30 ppm, so that the content of the harmful element N of the IF steel type is further reduced, the content of interstitial atoms is lower, the deep drawability is better, and the strength is higher. The method comprises a RH smelting step; and the nitrogen increment is not higher than 3 ppm, so that the support of the smelting method is provided to the IF steel finally obtaining the content of N not higher than 30 ppm. A block is added to a steel liner of a dipping pipe in a vacuum chamber of a RH smelting furnace, and is positioned below a slag line and above a steel liquid level, so that the crack of the dipping pipe is blocked, a refractory material is prevented from being stripped in atmosphere to enter steel liquid to increase nitrogen, the nitrogen in the atmosphere can be stopped ...

The invention discloses a method of using a sampler, and relates to the technical field of molten steel sampling. The method comprises the steps of inserting the sampler in molten steel from a sampling location to acquire a sample, wherein inserting depth is no less than 600mm; rapidly lifting the sampler after keeping in the molten steel for 4-6 seconds, vertically standing and slowly air-cooling for 20-40 seconds; and slowly water-cooling the sampler in water for 5-10 seconds, taking out the sample, and chilling the sample in the water for 5-15 seconds. According to the sampler using method disclosed by the invention, through modifying and curing furnace rear top slag, success rate of sampling is effectively increased, and height and regular shape of the top of the sample are guaranteed; the sample is uniformly molten in a sampler barrel through a reasonable cooling way, and thus uniformity and representativeness of sampling are guaranteed.
