Technology and device for producing rock wool from molten blast furnace slag

Abstract

The invention discloses a technology and device for producing rock wool from molten blast furnace slag. The device comprises a cupola furnace. The cupola furnace is fixedly installed on a four-roller centrifugation machine for centrifuging molten blast furnace slag. A fold beating machine for flattening folds and rolling rock wool is installed below an outlet of a wool collection machine, one side of the fold beating machine is provided with a curing furnace used for curing so as to improve stress, one side of the curing furnace is provided with a first cutting device and a second cutting device which are used for slicing rock wool, and throwing and pulling, stirring forming, wool collection, fold beating, curing, cutting and other processes are carried out. According to the technology and device for producing rock wool from molten blast furnace slag, the cupola furnace and the four-roller centrifugation machine are combined into a whole, installation investment of equipment is reduced, the production cost is reduced, the weighed blast furnace slag value and the input adhesive, dustproof oil, water repellent and resin values are put in proportion, stirring forming, wool collection, fold beating, curing, cutting and other processes are carried out, the good production quality of rock wool is ensured, and the heat insulation effect is improved.

Description

technical field [0001] The invention relates to the field of rock wool production, in particular to a process and a device for producing rock wool with molten blast furnace slag. Background technique [0002] Rock wool products are internationally recognized as the main energy-saving materials in the "fifth conventional energy source" because of their excellent fireproof and thermal insulation properties. Every ton of rock wool products used for insulation in buildings can save energy equivalent to at least 1 ton of oil a year, which is in line with the trend of low carbon, energy saving, and emission reduction, so it is an ideal building insulation material. The extensive use of rock wool for construction provides the possibility for my country to build more green and environmentally friendly buildings, protects the environment by effectively reducing energy consumption and carbon emissions, and makes due contributions to improving people's living environment.

AI Technical Summary

Problems solved by technology

[0003] However, the existing rock wool production process is relatively complicated. The cupola and the four-roller centrifuge are separated, and the equipment will undoubtedly increase the cost. Moreover, the rock wool insulation effect produced by the existing rock wool production process is not ideal. Some auxiliary materials in production The quality of the rock wool is poor due to the different feeding
