The invention discloses a large electric furnace
system, belongs to the technical field of rock
wool board production equipment and mainly relates to a rock
wool board electric furnace
system. The large electric furnace
system is used for solving the problems that in the prior art, the production scale of rock
wool is small, the energy
utilization rate is low, and the pressure is brought to the environment. The large electric furnace system comprises
raw material feeding devices, electric furnace devices,
fiber forming devices, wool collection devices, forming devices, curing devices and subsequent treatment structures; each
raw material feeding device comprises an external feeding conveying belt, a feeding tank, a conveying belt, a material-mixing device and a material-distributing device; each electric furnace device comprises a furnace body, and
stream openings are formed in the side walls of the lower ends of the furnace bodies; each
fiber forming device comprises a centrifugal
machine, and melts flowing out from the electric furnace devices are subjected to centrifugal
fiber-forming treatment; the wool collection devices are used for collecting and arranging fibers obtained bytreatment of the fiber forming devices into rock wool
layers; the forming devices are used for pressing forming of the rock wool
layers, and thus rock wool felt is formed; the curing devices are usedfor curing forming, and thus required rock wool boards are formed; and the subsequent treatment structures are used for
cutting and packaging the obtained rock wool boards. A public system comprisesa public water system, a public gas circulating system and a public recycling system, wherein the public water system is used for providing cooling circulation water for the two electric furnace systems and conducting recycled
water treatment. The production efficiency of an enterprise is effectively improved, the cost investment of the enterprise is reduced, and the product quality is high.
