Embodiment Construction

[0030] as attached figure 1 As shown in the figure, the three-hole evenly distributed orifice with controllable flow of high-temperature liquid slag used to meet the short-process production of mineral wool is characterized by a nozzle inner bush made of isostatic graphite, and the inner middle of the nozzle inner bush is There are three evenly distributed slag outlets on the end face, one of which is the currently used hole, and the other two slag outlets are spare slag outlets, and the same isostatic pressure is filled in the spare slag outlets. Graphite, the upper end of the slag outlet is provided with a fine-tuning lift control stopper.

[0031] When working, the currently used hole is used for a period of time, and it cannot be used due to the enlarged hole diameter. After being blocked, the second slag outlet will be drilled for use. After the second hole is used for a period of time, it cannot be used due to the enlarged hole diameter. After the use is blocked, the th...

Abstract

The invention discloses a flow-controllable orifice with three uniformly distributed holes for high-temperature liquid slag. The flow-controllable orifice is characterized in that three uniformly distributed slag orifices are arranged on an end surface of the inner middle of a nozzle inner bushing made of isostatic graphite materials, only one hole is utilized in each procedure, the other two standby slag orifices are filled with identical isostatic graphite, and stopper rods at the upper ends of the slag orifices can be finely adjusted and lifted, so that the flow of each slag orifice can be controlled. The flow-controllable orifice has the advantages that the service life of the flow-controllable orifice for the high-temperature liquid slag can be prolonged and can be identical to the service lives of graphite crucibles, and the replacement frequency can be reduced; blockage of liquid slag flow can be effectively prevented, the flow-controllable orifice is reliable and is long in service life, and the running cost can be effectively reduced; requirements of short-process mineral wool manufacturing technologies can be met; the flow-controllable orifice is favorable for meeting market requirements on broad development prospects of mineral wool and products of the mineral wool.

Description

technical field [0001] The invention relates to a three-hole uniformly distributed orifice with controllable flow rate of high-temperature liquid slag used for short-process production of mineral wool. The invention belongs to the technical field of slag melting equipment. Background technique [0002] The "Twelfth Five-Year Plan" puts forward the strategic goal of energy conservation and emission reduction, and building a resource-saving and environment-friendly society has become the primary task of the industrialization and modernization development strategy. As the main force in the process of industrialization, the iron and steel industry is also facing opportunities and challenges. The process energy consumption of blast furnace ironmaking accounts for about 60% of the total energy consumption of the iron and steel industry. Blast furnace slag is a kind of solid waste discharged from blast furnace ironmaking. Its treatment process not only consumes a lot of energy, b...
