Example Embodiment

[0029] With reference to the accompanying drawings, the specific implementation of the present invention will be further described in detail through the description of the embodiments to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0030] Such as figure 1 The structure of the present invention shown is a flow control device for the production of slag wool, rock wool, glass-ceramics, and cast stone products in an induction furnace. The induction furnace is provided with a nozzle brick 8 and the nozzle The brick 8 is fixed at the bottom of the induction furnace by a water-cooled tray 9 and sealed by pressing the outer tapered sealing surface.

[0031] Compared with the prior art, the production process of using induction electric furnace to produce slag wool, rock wool, glass-ceramics, and cast stone has the characteristics of high molten pool temperature and wide ap...

Abstract

The invention discloses a flow control device for an induction furnace to produce mineral cotton, rock wool, glass ceramics, cast stone products and the like. A nozzle brick (8) is fixed at the bottom of the induction furnace through a water cooling tray (9), and the flow control device is provided with a water cooling eking body (5). The lower end of the water cooling eking body (5) is fixedly connected with a graphite stopper (6), and the lower end of the graphite stopper (6) is provided with a tapered stopper head (7) which is matched with a nozzle of the nozzle brick (8). The water cooling eking body (5) is connected to a rotating driving mechanism (2) through a flange and a torque limiter (1). The flow control device conducts precise control over melt supplying amount, flow is not limited by the temperature and the component of melt, adjusting can be achieved at will, the control precision is high, the influence of manufacturing of the stopper and the eking body and mounting errors on sealing can be removed, and the fact that the nozzle is closed reliably at any time can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of inorganic material production technology. Specifically, the present invention relates to a flow control device for induction furnace production of slag wool, rock wool, glass-ceramic and cast stone. Background technique [0002] At present, in the production process of domestic slag wool and rock wool, most manufacturers use cupolas as melting equipment, melt basalt, slag, dolomite, etc. with coke in the cupola and supply them to fiber-forming equipment to make fibers. Melting ore and other raw materials will cause a lot of energy consumption and serious environmental pollution. [0003] The composition of the cupola furnace is controlled by the amount of charge into the furnace, and the reaction cycle is long; the control of the melt temperature and supply is adjusted by the coke ratio and the tuyere. There is a direct relationship between temperature and supply. When the temperature rises, the supply i...
