A two-way baking cover for a steel bucket

Abstract

The invention discloses a two-way baking cover for steel ladles and tanks for metallurgical casting. A burner is arranged in the middle of the lower bottom of the baking cover body, and a combustion-supporting air pipe and a gas pipe are arranged inside. The combustion-supporting air pipe and the gas pipe are all connected to the The burner is connected, the side wall of the baking cover body is provided with a combustion-supporting air inlet and a gas inlet, the combustion-supporting air inlet is connected with the combustion-supporting air pipe, and the gas inlet is connected with the gas pipe; the middle of the upper bottom surface of the baking cover body is set There is a guide tube, and the body of the baking cover is provided with a plurality of channels for channeling through up and down; the upper surface of the body of the baking cover is provided with a plurality of inlets of the exhaust channels, and the inlets of the exhaust channels are connected with the inlets of the oven. The tail flame outlet on the side wall of the grill cover body is connected. When the present invention is in use, the high-pressure jet flame flow is concentrated. The flame flow bakes the bottom and corners and turns back, and enters another steel tank above from the flame channel to continue baking, and only uses 1 / 2~1 / 3 of the energy consumption of baking a steel tank .

Description

technical field [0001] The present invention relates to the roasting of metallurgical casting pouring liquid metal containers, especially the baking of iron and steel continuous casting or casting production of steel ladles or tin cans for containing liquid iron and steel. Background technique [0002] The baking mode of most existing steel drums and iron tanks is the open baking mode that has been followed for hundreds of years. The refractory lining of steel drums and iron ladles is baked by fire from normal temperature to high temperature of 900 -1150°C, it needs to be kept warm for dozens of hours, waiting for the temperature to pass through the refractory lining to remove crystal water substances, burning a lot of energy and only a few can be conducted to the refractory lining, and most of the combustion heat is evacuated, correspondingly Harmful substances generated by combustion reactions such as carbon, hydrogen, and nitrogen are also exhausted and pollute the atmosp...

Problems solved by technology

[0003] The disadvantage of the existing roaster used in the iron and steel industry is that most of the flame of the combustion device cannot reach the bottom, especially the corner of the steel drum at the bottom, and the corner of the adjacent side wall conducts heat and dissipates heat in two dimensions. Therefore, it absorbs heat The amount is approximately a multiple of

[0023] In addition, a kind of ladle series baking device also has the disadvantage that: the combustion device (2) is arranged around the hot gas channel (6) and the mouth is downward, so

In order to further pursue low-carbon production and full utilization of energy, there is an urgent need for a technical solution that can increase the temperature at the corner of the bottom ladle to improve the energy-wasting defect of the ladle serial baking device
