Fire clay blasting preventing baking method of steel ladle mechanism

Abstract

A fire clay blasting preventing baking method of a steel ladle mechanism comprises the steps that the cool state steel ladle mechanism with a replaced water gap and a replaced sliding plate is placed above an adjustable nozzle type baker, wherein the adjustable nozzle type baker comprises an outer cylinder, a gas pipe is arranged in the outer cylinder, and a gas pipe fixing and height adjusting mechanism is arranged on the side wall of the outer cylinder; the height of the gas pipe is adjusted, the combining face of the upper water gap and the upper sliding plate in the steel ladle mechanism is located in a nozzle combusting gas flame high-temperature area, and gas flowing out of a nozzle is ignited for baking; during baking, the combustible gas flow sequentially becomes high, low and high, and the gas supply time of the high-flow combustible gas is 2-3 times of the gas supply time of the low-flow combustible gas; and the total baking time is controlled within 30-60 min, an organic bonding agent and water in fire clay used for sealing of the sliding plate in the steel ladle mechanism are decomposed and volatilized step by step, and the fire clay is molded and stabilized. The organic bonding agent and the water in the fire clay used for sealing of the sliding plate can be decomposed and volatilized step by step, and the safety hazard of steel fleeing caused by instant fire clay blasting during molten steel casting on is avoided.

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...

Problems solved by technology

Neither the invention nor the traditional off-line baking ladle sliding plate and the replacement method of the drain outlet have solved the problem of setting the seal with fire mud for baking after the cold ladle mechanism replaces the slide plate. the harm of
