Embodiment

[0052] See figure 1 with figure 2 In the system and method for preparing mineral wool board or felt by using hot slag provided in this embodiment, metallurgical hot slag (such as blast furnace slag, steel slag, ferroalloy slag, etc.) Directly flow into the heating and melting conditioning system through the slag ditch, or pour into the heating and melting conditioning system through the tank, and preferably add auxiliary materials (conditioning and tempering materials or conditioning materials and fluxing materials), and pass the auxiliary materials through a matching upper The material system is added to the heating, melting and tempering system; the heating, melting and tempering system controls the temperature at 1450°C-1600°C, the holding time is 6-24 hours, and at the same time combines methods such as adding an appropriate amount of auxiliary materials to make the slag tempered and tempered. Qualified melt of mineral wool board.

[0053] See figure 1 , the system of ...

Abstract

The invention discloses a system and method for manufacturing a mineral wool board or felt through hot slag. The system comprises a heating and melting conditioning system, a chute system, a centrifugal fiber forming machine, a cotton collecting machine, a pendulum bob machine, a forming conveyor, a weighing conveyor, a pleating machine, a curing oven, a cooling conveyor, a measuring device, a slitting machine, a first conveyor, a transverse cutting machine, a second conveyor and a packager. The method is a technological process implemented through the system. According to the system and method, deep utilization that the metallurgical molten slag is directly manufactured into the mineral wool board or the felt or other products in the subsequent process of hot slag utilization is achieved, sensible heat recovery of the metallurgical hot slag is fully achieved, consumption of mineral resources and environmental pollution are reduced, and the system and method are closer to the target of achieving high value-added utilization and zero release of the metallurgical slag.

Description

technical field [0001] The invention relates to a technology for preparing mineral wool boards or mineral wool felts from hot slag in iron and steel metallurgy, and belongs to the energy-saving and emission-reduction technology of solid waste comprehensive utilization and slag sensible heat recovery in the iron and steel metallurgy field. Background technique [0002] Ironmaking, steelmaking and ferroalloy production are important process units of steel production. During the production process, a large amount of iron and steel metallurgical slag, such as blast furnace slag, steel slag, and ferroalloy slag, will be produced. The total amount has exceeded 300 million tons. The National Development and Reform Commission and the Ministry of Industry and Information Technology have set target values ​​of 70% and 75% for the utilization rate of metallurgical slag in the relevant plans of the "Twelfth Five-Year Plan". An important task, the development and utilization of steel ...
