Embodiment 1

[0024] Embodiment one: if figure 1 As shown, the induction furnace for continuous production of high-temperature rock / mineral wool raw material melt 8 includes a furnace body 1, which is provided with a refractory crucible 2 that does not generate induction eddy currents, and the outer periphery of the refractory crucible 2 is installed There is an induction coil 3, and a metal cylinder 4 with a melting temperature greater than 1600°C is set inside the refractory crucible 2, and a liquid collection gap 5 is provided between the outer peripheral wall of the lower part of the metal cylinder 4 and the refractory crucible 2, so that The outer periphery of the side wall of the metal cylinder 4 near the bottom of the refractory crucible 2 is provided with a liquid outlet, and the wall of the refractory crucible 2 corresponding to the liquid collection gap 5 is provided with a melt overflow port 21; the refractory The bottom of the material crucible 2 is provided with a molten iron d...

Embodiment 2

[0036] Embodiment two: if figure 2 As shown, this embodiment is basically the same as Embodiment 1, except that the upper side wall of the refractory crucible 2 is provided with an inert gas inlet 6 communicating with the liquid collection gap 5 . When this embodiment is working, inert gas is continuously filled into the liquid collection gap 5 through the inert gas inlet 6, so that the outer surface of the metal cylinder 4 is under the protection of the inert gas, and the outer surface of the metal cylinder 4 is avoided. Oxidation loss on the surface greatly improves the service life of the metal cylinder 4 .

Embodiment 3

[0037] Embodiment three: as image 3 As shown, this embodiment is basically the same as Embodiment 1, except that the bottom of the metal cylinder 4 is plugged and fixed on the bottom of the refractory crucible 2, and the liquid outlet channel is arranged on the metal cylinder 4 A liquid outlet hole 41 near the outer periphery of the side wall of the bottom of the refractory crucible 2 .

[0038] The refractory subdividing body 9 is conical; the refractory subdividing body 9 is a metal body with a melting temperature greater than 1600° C. and is hollow.

Abstract

The invention discloses an environment-friendly induction electric furnace for continuously producing high-temperature rock / mineral wool raw material melt. ring, the refractory crucible is set with a metal cylinder with a melting temperature greater than 1600°C; the inner cavity of the metal cylinder is provided with a refractory distribution body, and an annular gap is formed between the refractory distribution body and the metal cylinder Melting gap; the inner cavity of the metal cylinder is provided with a refractory material distribution body, and an annular melting gap is formed between the refractory material distribution body and the metal cylinder, which increases the heating surface area of ​​the material and improves the melting speed of the material , avoiding the support and obstruction of the follow-up materials by the central material; the invention has a simple structure, greatly improves the production efficiency and economic benefits of rock / mineral wool manufacturing enterprises, and also has great social benefits.

Description

technical field [0001] The invention relates to the field of rock / mineral wool raw material manufacturing equipment, in particular to a high-temperature molten rock / mineral wool raw material to produce rock / mineral wool equipment. Background technique [0002] Melting slag, basalt, etc. through a cupola to produce rock / mineral wool is a widely used process in the manufacture of rock / mineral wool. The cupola uses the heat generated by the combustion of coal or gas to melt the rock / mineral wool raw material. The rock / mineral wool raw material is mostly an insulator, so it absorbs heat slowly and wastes energy seriously. In particular, the cupola emits a large amount of polluting gas, which is harmful to the environment. , facing the status quo of being shut down. Moreover, because the melting temperature of the rock / mineral wool raw material is relatively high, and the rock / mineral wool raw material lacks the characteristics of metal materials, it is difficult to melt it by e...
