Embodiment Construction
[0019] A method for maintaining the shell of a large-scale smelting blast furnace, which includes:
[0020] A. Set online flexible support:
[0021] A1. Set the load-reducing supporting well-shaped beam on the furnace frame;
[0022] A2. A flexible support system spring group is placed between the load-reducing supporting well-shaped beam and the furnace shell ring beam; to ensure the safety of the furnace shell during online production;
[0023] B. Replacement of the furnace shell of the deformed section during shutdown:
[0024] B1. Utilize the load-reducing support beam and the furnace shell ring beam, and evenly arrange the lifting, deviation-correcting and sliding devices in the space between the beams;
[0025] B2. Set up a material receiving platform at the three-layer platform of the furnace shell, and set up two cranes at the furnace shell body as furnace shell reverse, hoisting and transfer facilities;
[0026] B3. After the jacking device is pre-loaded, cut and r...

The invention relates to a smelting blast furnace and in particular relates to a large smelting blast furnace shell. A large smelting blast furnace shell position adjusting device comprises cross support beams below original ring beams of a furnace shell, wherein a load shedding and fall stopping device, hydraulic jacking devices, a deviation rectifying device and sliding devices are arranged on each cross support beam; the furnace shell is arranged between the cross support beams; each load shedding and fall stopping device comprises a group of spring support components arranged around the outer ring of the furnace shell; each spring component is fixed on each cross support beam and supports each ring beam of the furnace shell. The device has the beneficial effects that the safety production requirement that continuous sedimentation of the furnace shell is slowed down before furnace shutdown can be met and the construction requirements of jacking and deviation rectification of the upper furnace shell and the furnace top during furnace shutdown can be also met; the input cost is reduced due to reutilization.
Description
technical field [0001] The invention relates to a smelting blast furnace, in particular to a large-scale smelting blast furnace shell. Background technique [0002] Due to its huge size, the smelting blast furnace is divided into sections, and each section is rigidly connected. In long-term production and use, due to the shedding of refractory materials and the damage of coolers, the furnace shell will subside under heat and pressure, and the hard connection may deform and crack the furnace shell during the settlement process; on the other hand, due to the extremely high Therefore, the inclination of the furnace shell is also likely to cause aggravated damage to the furnace shell and affect safe production. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects, and provides a method for maintaining the shell of a large-scale smelting blast furnace. The invention can not only meet the safety production requirements of slowing d...
