Description

Coarse copper tapping port refractory brick masonry structure

Technical Field

The utility model relates to a metal smelting technical field, concretely relates to resistant firebrick masonry structure of blister copper taphole.

Background

Flash converting is an oxygen-enriched suspension smelting technology, oxygen-enriched air, copper matte particles, converting fine smoke dust and limestone powder are added into a nozzle at the top of a reaction tower in a proper proportion, gas and mixed materials are intensively mixed and then are sprayed into the reaction tower at a high speed, and the gas is heated to generate extreme volume expansion, so that the materials are in a suspension state, are fully distributed on the cross section of the whole reaction tower and generate strong oxidation exothermic reaction. The overheated melt which finishes the interactive reaction in the reaction tower falls into a sedimentation tank, and the slag and the copper matte settle and separate due to different specific gravities, so that when the blister copper is discharged from the furnace mouth of the flash furnace, a large-pressure-plate water jacket of a discharge hole needs to be used at the furnace mouth part of the flash furnace. The vertical height between the crude copper discharge outlet and the inner surface of the inverted arch of the furnace bottom is 400-500mm. The crude copper discharge port discharges frequently, the crude copper discharge port is easy to damage, and the crude copper erodes the refractory lining of the arch springing brick. When the water jacket of the large pressure plate at the discharge outlet is replaced, the damaged refractory bricks in the furnace body around the water jacket need to be cleaned. However, the existing blister copper discharging port is lined with different large refractory bricks, and when the large pressure plate water jacket of the discharging port is replaced, the refractory bricks are not convenient to be dug and repaired; and secondly, the complete fitting of the eye brick and the lining brick of the water jacket opening furnace body cannot be ensured, and the risk of copper leakage is increased. In addition, the strength of manual cleaning operation is greatly increased due to the penetration of copper liquid to gaps of refractory bricks.
