Problems solved by technology

The existing baking equipment used in the iron and steel industry also has the problem that the high-temperature part of the downward flame flow of the combustion device and the return flue gas flow are opposite to each other, and there is an airflow pad at the bottom of the barrel. The strength of the airflow pad The size is proportional to the high temperature part of the flame flow down the combustion device
The reason is that the good thermal resistance of refractory materials restricts the heat transfer rate, causing a large amount of energy and heat energy for baking and combustion to flow only on the surface of refractory materials, and most of the dynamic heat energy of combustion is helplessly lost.

Abstract

The invention discloses a cover for barrel roasting. The cover comprises an arch hoop (15), an arch (7) arranged in the arch hoop (15) in a bearing mode and an arch cover (3) arranged on the arch (7). An interlayer cavity is formed between the arch (7) and the arch cover (3), a roasting burning device is disposed in the interlayer cavity, a fire inlet (2) is formed in the center of the arch cover (3), the fire inlet (2) guides flames to heat a roasting device, the roasting device is provided with multiple gas pipes (4) and air pipes (5) of the same number, the gas pipes (4) and the air pipes (5) are distributed in a radial mode with the axis as the center, each gas pipe (4) and front section fluid of the corresponding air pipe (5) are communicated with the same double-pipe nozzle (9), the double-pipe nozzles (9) are distributed circumferentially to eject the flames, the flames roast two barrel liners made of fire-resistant materials, and all the directions of the ejected flames are towards the upper portion of an intersection corner portion (21) of a barrel body and a barrel bottom.

Description

technical field [0001] The invention relates to metallurgical baking of liquid metal ladles and cans, especially the baking of steel ladles and cans for casting and continuous billet casting. Background technique [0002] At present, the purpose of baking steel or iron barrels in the foundry and iron and steel industries is to make the refractory lining lose water molecules, and prevent the hydration crystals from suddenly decomposing water molecules when containing molten steel or iron. The water molecules mix and deflagrate, blowing up the refractory material layer and pushing molten steel or iron to splash out of the tank, causing casualties to the operator. Another purpose is: if the refractory lining of the tank is baked to a high enough temperature, the molten steel or iron will absorb less physical heat energy carried by the molten steel or molten iron. Therefore, the smelting temperature can be reduced to improve energy efficiency. People in this profession know tha...
