The burner 30 and the fluxing electrode 40 are arranged in the embodiment, so that electric heating and flame heating can be simultaneously carried out, the melting effect is better, the quality of basalt liquid is improved, and the wire drawing effect is stabilized; the insulating belt 50 is arranged between the furnace body 10 and the furnace cover 20, so that bricks of the furnace cover 20 are not electrified, the power loss is reduced, the service life of the bricks is prolonged, and the stable operation of the kiln is ensured.
In this embodiment, the insulating tape 50 is made of insulating firebricks. The brick materials of the furnace body 10 and the furnace cover 20 are common refractory bricks, the common refractory bricks can conduct electricity under the condition of high temperature, the refractory bricks can also generate current, the current generated by the furnace cover 20 can cause electric loss and waste energy, and the insulating refractory bricks arranged between the furnace body 10 and the furnace cover 20 can prevent the furnace cover 20 from generating current and concentrate electric energy for melting basalt in the furnace body 10.
In this embodiment, the width of the insulating tape 50 is 40 to 100 mm. The width of the insulating tape 50 is too small, and the insulating effect is not good; the width of the insulating tape 50 is too large, the usage amount of insulating refractory bricks is increased, and the manufacturing cost of the kiln structure is increased; preferably, the width of the insulating tape 50 of the present embodiment is 70 mm.
In the embodiment, the central height of the insulating tape 50 is 40-100 mm away from the liquid level of the basalt. The liquid level of the basalt has a certain distance with the insulating belt 50, so that the current in the basalt liquid is prevented from flowing to the furnace cover 20 part, and the insulating effect of the insulating belt 50 is ensured; the insulating tape 50 cannot be too far away from the furnace bottom, and excessive electric energy can be lost by bricks above the basalt liquid level; preferably, the center height of the insulating tape 50 of the present embodiment is 70mm from the basalt liquid level height.
In this embodiment, a plurality of burners 30 are provided, and the flames of the burners 30 are sprayed toward the basalt liquid. The flame of the burner 30 heats the basalt from above, and the basalt is matched with electric heating, so that the basalt liquid is melted more uniformly, and the quality of the basalt liquid is improved.
In this embodiment, the outer wall of the furnace body 10 is provided with an insulating layer 60. Specifically, the heat insulating layer 60 is made of an asbestos heat insulating plate. The heat-insulating layer 60 can reduce the heat loss of the furnace body 10, save energy and ensure the heating effect.
In this embodiment, a steel plate 70 is disposed outside the insulating layer 60. The steel plate 70 is provided with electrode holes, and the steel plate 70 has certain compressive strength, so that the furnace body 10 can be protected, and the stress on refractory bricks can be reduced.
In this embodiment, the insulating refractory brick has an upper limit of high temperature resistance higher than 1500 ℃. The working temperature of the kiln is about 1500 ℃, and the insulating refractory bricks need to have insulating performance within the working temperature range, so the upper limit of the high temperature resistance of the insulating refractory bricks must be higher than the working temperature of the kiln. Preferably, the upper limit of the high temperature resistance of the insulating refractory of the present embodiment is about 2000 ℃.
