The tundish heater mainly consists of a heating burner, a rotating arm, a gas pipeline system, an air pipeline system, and other components. Its primary function is to heat the intermediate steel ladle in the steelmaking plant, thereby reducing temperature drop and heat loss within the tundish.

Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. ZWKB Features of energy-saving dryers:

1 ) Accelerate the turnover of tundishes and ensure smooth production. Since this baking device improves combustion efficiency and baking temperature while maintaining relatively stable heat supply, it can intensify the tundish baking process, enabling rapid baking of semi-dry materials in tundishes, thereby shortening the tundish baking time and guaranteeing smooth production.

2 ) It significantly reduces fuel costs and greatly improves thermal efficiency, with an estimated fuel savings. 30% Above, the equipment’s return on investment is less than. 6 month.

3 ) By increasing the lifespan of tundishes, raising the tundish baking temperature, and reducing the temperature difference between the molten steel and the tundish lining, we have significantly reduced the damage to the refractory materials caused by rapid heating, thereby minimizing furnace lining erosion. Additionally, this approach has greatly decreased the frequency of premature tundish removal due to cold iron formation at the tundish bottom—factors all contributing to an extended tundish service life.

4 Low-calorific gas can be used for drying ladles. However, to ensure the proper drying temperature of the tundish, high-calorific fuels such as coke oven gas and heavy oil are typically employed as fuel sources; low-calorific fuels like blast furnace gas cannot be used. Oxygen-enriched or fully oxygen-fired tundish drying systems enable the complete combustion of low-calorific blast furnace gas, achieving higher theoretical combustion temperatures. This effectively utilizes low-calorific gas resources and helps conserve high-calorific gas resources.

5 ) Reducing flame leakage through the intermediate ladle cover and extending its service life—traditional intermediate ladle heating devices lack waste heat recovery systems, causing high-temperature flue gases to directly escape from the edges of the ladle cover, thereby shortening the cover’s lifespan.

However, regarding the baking of the tundish, the general requirement is that it must be completed before starting the casting. 1-2h Inside, quickly bake to 1000-1100 ℃—this way, you can save energy and make it easier to use.
