A kind of steelmaking auxiliary material drying device

Abstract

The invention relates to a drying device for steelmaking auxiliary materials, comprising an outer casing, a drying box, a main gas transmission pipe and an auxiliary gas transmission pipe. The drying box is provided with a drying chamber with an open top, and the diameter of the drying chamber is from the middle to the upper and lower ends. Gradually become larger, the above-mentioned outer casing is sleeved on the outside of the drying box, a shunt chamber is formed between the outer casing and the drying chamber, and a first air inlet hole and a second air inlet hole are arranged on the side wall of the drying box; the above-mentioned main gas transmission The pipe is used to guide and ventilate the shunt chamber, the above-mentioned auxiliary gas transmission pipe runs through the middle of the bottom wall of the drying box and the blowing end extends into the drying chamber, the upper end of the drying chamber is installed with a fairing, and the intake end of the auxiliary gas transmission pipe is connected to the top of the fairing; A plurality of electric heating coils are installed on the inner wall of the outer casing. The steel-making auxiliary material drying device of the present invention is configured through the shunt chamber between the drying box and the outer shell, the shunt chamber is equipped with an electric heating ring, the auxiliary materials are simultaneously heated inside and outside, the heating area is large and uniform, the drying efficiency is high, and the hot air is used in circulation. The pipeline structure is reasonable.

Description

technical field [0001] The invention relates to the technical field of steel-making equipment, in particular to a drying device for steel-making auxiliary materials. Background technique [0002] In the process of iron and steel refining, iron and steel plants need to add certain auxiliary materials to assist the refining of steel. When the humidity of the auxiliary materials added during iron and steel refining is too high, it is very likely to cause damage to the steel-making equipment and sound explosion in the furnace. Therefore, it is necessary to dry the auxiliary materials before adding the auxiliary materials. At present, the existing drying device usually adopts hot air intake, the drying pipeline of this type of drying device is single, the heating area of ​​the auxiliary materials is small, and the drying is uneven. It is difficult to completely dry the inside of the piled up accessories, the drying efficiency is low, the pipeline structure is unreasonable, and th...
