Abstract

The ladle mechanism fire mud anti-blasting method includes: placing the cool ladle mechanism after replacing the nozzle and the slide plate on the adjustable nozzle type roaster; the adjustable nozzle type roaster includes an outer cylinder, and the outer cylinder is equipped with Gas pipe, the side wall of the outer cylinder is equipped with a gas pipe fixing and height adjustment mechanism; adjust the height of the gas pipe so that the joint surface of the upper nozzle and the upper slide plate in the ladle mechanism is located in the high temperature area of ​​the gas flame burned by the nozzle, and then ignite the gas flowing out of the nozzle Carry out baking; when baking, the flow rate of combustible gas is high first, then low and then high, and the gas supply time of high flow combustible gas is 2-3 times that of low flow combustible gas; the total baking time is controlled at 30-60 minutes , the organic binder and water in the fire clay used for sliding plate sealing in the ladle mechanism are gradually decomposed and volatilized, so that the fire clay is formed stably. The invention can gradually decompose and volatilize the organic binder and moisture inside the fire clay, and avoid the safety hazard of steel escaping caused by fire clay blasting at the moment when molten steel is poured.

Description

technical field [0001] The invention relates to a baking method for refractory materials, which belongs to the field of iron and steel production safety, and in particular to a blasting-proof baking method for fire mud of a ladle mechanism. Background technique [0002] The steel ladle is also called the steel ladle. It is used in steelmaking plants and foundries to receive molten steel in front of the open hearth furnace, electric furnace or converter, and cooperate with the continuous casting machine for pouring operations. The bottom of the ladle is usually equipped with a nozzle and a sliding plate mechanism, and there is an opening in the middle of the sliding plate. , the nozzle cooperates with the opening of the slide plate to flow molten steel into the tundish, and the slide plate and nozzle of the ladle mechanism are responsible for the molten steel in the ladle to the tundish according to the pulling speed of the casting machine to achieve flow control, sealing prot...
