High-titanium molten blast furnace slag hot charging furnace device

Abstract

The invention relates to the field of hot-state blast furnace smelting, in particular to a high-titanium-type molten blast furnace slag heat loading furnace device which effectively solves the block of slag outlets, so that the hot-state blast furnace slag is safely guaranteed to enter a carbonization furnace, the problem that the hot-state blast furnace slag is directly introduced into the carbonization furnace to cause huge impact to the carbonization furnace is also avoided. The device comprises a device body, wherein the device body comprises a hot slag inlet, a slag outlet and a gate sealing device arranged in the device body, the gate sealing device is used for sealing the slag outlet by being tightly attached to the slag outlet, and a slag skimming plate structure is arranged at thehot slag inlet. The device is simple in structure, convenient to operate, low in purchasing cost and capable of being widely applied to metallurgy.

Description

technical field [0001] The invention relates to the field of hot blast furnace smelting, in particular to a device for thermally charging high-titanium molten blast furnace slag into a furnace. Background technique [0002] At present, there is no precedent of hot blast furnace slag being smelted into the furnace at home and abroad. The hot blast furnace slag is transported to the carbonization workshop by the slag tanker. Due to equipment installation requirements, the blast furnace slag cannot be directly poured into the carbonization furnace by the slag tanker, and the blast furnace slag has 1300 The high temperature above ℃ is liquid, and the liquid blast furnace slag will splash on the surrounding equipment during the process of pouring directly into the furnace, which will seriously affect other equipment and pose a safety hazard. During the smelting process, the carbonization furnace needs to be sealed to ensure gas recovery and high thermal efficiency. The ordinary c...

[0002] At present, there is no precedent of hot blast furnace slag being smelted into the furnace at home and abroad. The hot blast furnace slag is transported to the carbonization workshop by the slag tank truck. Due to the installation requirements of the equipment, the blast furnace slag cannot be directly poured into the carbonization furnace by the slag tank truck, and the blast furnace slag has 1300 The high temperature above ℃ is liquid, and the liquid blast furnace slag will splash on the surrounding equipment during the process of pouring directly into the furnace, which will seriously affect other equipment and pose a safety hazard

During the smelting process, the carbonization furnace needs to be sealed to ensure gas recovery and high thermal efficiency. Using a common chute can not seal the carbonization furnace material inlet, or directly dumping the furnace cover can not guarantee the seal. The opening and closing of the sealing cover requires manual operation, which is difficult. big and unsafe
