Abstract

The utility model relates to a successively smelting furnace for manufacturing quartz tubes and rods, and mainly aims to solve a problem that the present smelting furnace for manufacturing quartz tubes and rods can only manufacture one quartz tube and rod for one time. The successively smelting furnace includes a furnace body, a heater, a heat insulation material, a large furnace cover, a small furnace cover, a tungsten crucible, a discharge platform, core rods, a feeder nose, etc. Two or more discharge holes are formed on the discharge platform, and core rods are correspondingly arranged above the discharge holes. The utility model has the advantages as follows: the successively smelting furnace is suitable for manufacturing relatively thin and small quartz tubes and rods, two or more tubes or rods can be manufactured for one time, the production efficiency is high, and the production cost is low.

Description

A kind of continuous induction melting furnace of producing silica tube, rod

Technical field:

The utility model relates to a kind of continuous induction melting furnace of producing silica tube, quartz pushrod.

Background technology:

The every stove of continuous induction melting furnace of existing production silica tube, quartz pushrod can only be produced a silica tube or quartz pushrod, and shortcoming is that production efficiency is low, the product cost height.

Summary of the invention:

Technical problem to be solved in the utility model provides an a kind of stove can produce two or the production silica tube of two above silica tubes or quartz pushrod, the continuous induction melting furnace of rod.

Above-mentioned purpose is achieved in that it comprises body of heater, well heater, lagging material, big bell, little bell, tungsten crucible, discharge pedestal, core bar, dog-house etc., we establish two or more discharge holes on discharge pedestal, all there is a core bar corresponding with it top of each discharge hole.

The utility model has the advantages that to be suitable for producing more tiny silica tube or quartz pushrod, a stove can be produced more than two or two, the production efficiency height, and production cost is low.

Description of drawings:

Fig. 1 is a cross-sectional view of the present utility model;

Fig. 2 is the plan structure synoptic diagram that is provided with the discharge pedestal of two discharge holes.

Embodiment:

With reference to Fig. 1,2, there is big bell 3 body of heater 4 tops, and discharge pedestal 9 is contained in the bottom of tungsten crucible 6, tungsten crucible is hung on the big bell, and the outside of tungsten crucible is well heater 8 and lagging material 5, and there is port lid 2 top of tungsten crucible, port has covered dog-house 1, and the upper end of core bar 7 is contained in port and covers; On discharge pedestal, establish 2 or 3 or 5 discharge holes 10, be contained in the core bar that port covers and also be respectively 2 or 3 or 5 with each discharge hole is corresponding.

Claims (1)

1. One kind produce silica tube, the rod continuous induction melting furnace, there is big bell (3) body of heater (4) top, discharge pedestal (9) is contained in the bottom of tungsten crucible (6), tungsten crucible is hung on the big bell, the outside of tungsten crucible is well heater (8) and lagging material (5), there is little bell (2) top of tungsten crucible, and port has covered dog-house (1), and the upper end of core bar (7) is contained in port and covers; It is characterized in that establishing two or more discharge holes (10) on discharge pedestal (9), all there is a core bar corresponding with it top of each discharge hole.
