Abstract

PURPOSE:To prolong the life of a core tube by dividing the tube into two parts in the longitudinal direction and using a material having superior heat insulation as the material of the upper division and a high strength material not reacting with scale as the material of the lower division. CONSTITUTION:A core tube 5 is divided into two parts in the longitudinal direction, and the 1st division 5a as the upper half is combined with the 2nd division 5b as the lower half and bound with a band. The 1st division 5a is made of a material having superior heat insulation such as alumina, silica, mullite or other refractory, and the 2nd division 5b is made of a material having superior strength and not reacting with scale such as SiC or Si3N4. The resulting divided core tube 5 has high thermal shock resistance, and the life is prolonged by 1.5-2 times that of a conventional tube.

Description

【発明の詳細な説明】 本発明は、誘導加熱炉の炉芯管に関するものである。[Detailed description of the invention] The present invention relates to a furnace core tube for an induction heating furnace.

はまだまだ満足できるものではなかった。As shown in Figures 1 and 2, the core of a conventional induction heating furnace! 'f1 was not made by combining divided bodies, but was formed integrally into a tubular shape. In addition, since rapid heating and cooling are performed many times, it is susceptible to thermal shock, and its lifespan is still unsatisfactory.

本発明は上記の実情に鑑みてなされたもので、熱衝撃に
強く、寿命の長い誘導加熱炉の炉芯管を提供することを
目的とするものである。The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a furnace core tube for an induction heating furnace that is resistant to thermal shock and has a long life.

本発明の誘導加熱炉の炉芯管は、長手方向に２分割して
、第１分割体と第２分割体に分け、これら第１分割体と
第２分割体とを組み合わせる構成にしたことを特徴とす
るものである。The furnace core tube of the induction heating furnace of the present invention is divided into two in the longitudinal direction into a first divided body and a second divided body, and the first divided body and the second divided body are combined. This is a characteristic feature.

本発明の誘導加熱炉の炉芯管は、上記のように長手方向
に２分割されているので、管状に比べ加熱による歪みが
生じ難い。このため本発明の炉芯管は熱衝撃に大変強く
、寿命が従来の炉芯管よりも１．５〜２倍長くなる。Since the furnace core tube of the induction heating furnace of the present invention is divided into two parts in the longitudinal direction as described above, it is less likely to be distorted by heating compared to a tubular shape. Therefore, the furnace core tube of the present invention is highly resistant to thermal shock and has a lifespan of 1.5 to 2 times longer than that of conventional furnace core tubes.

また本発明によれば、炉芯管が破損しても破損した方の
分割体だけを交換すればよいので、大変経済的である。Further, according to the present invention, even if the furnace core tube is damaged, it is only necessary to replace the damaged divided body, which is very economical.

２分割炉芯管はバンドで所々縛って固定しておく。Tie the two-part furnace core tube in place with bands to secure it.

以下、図面を参照して本発明の好適な実施例について説

are joined together and bound by a band (not shown). It is preferable that the first divided body 5a and the second divided body 5b are arranged vertically. Furthermore, the first divided body 5
By changing the material of a and the material of the second divided body 5b, a very effective furnace core tube 5 can be obtained. For example, if the upper first divided body 5a is made of a material with good heat insulation properties, and the lower second divided body 5b is made of a material that does not react with the scale and has excellent strength, the life will be even longer. A furnace core tube can be obtained.
