体の交換が行なわれている。(Problem that the invention aims to solve) In the case of these water-cooled gutters, the entire inner side wall and bottom of the gutters are in contact with the molten slag, resulting in a very high heat load, which may cause deformation of the steel shell in some cases. There is a risk of cracks forming and cooling water getting mixed into the high-temperature slag, causing a steam explosion.Therefore, water leakage detection and flow control are required, and if an abnormality occurs, the entire gutter is replaced.

3 is a drainage header, 4 is a monolithic refractory, 5 is a refractory brick, 6 is a coating, and 7 is a molten slag. The box-shaped jacket 1 constitutes a water channel group 9 by an internal partition plate 8. That is, the box-shaped jacket 1 has an independent metal unit structure with a length of about 1 to 2 m, and a water supply header 2 is piped to the lower end of one end in the length direction, and the box-shaped jacket 1 is partitioned in the vertical direction. The water channel group 9,
9, . . . are detoured along the length of the box jacket 1, and their terminal ends are connected to the drain header 3 at the upper end on the opposite side from the water supply header 2. Water supply header 2 and drainage header 3
are connected to water supply and drainage connection pipes not shown in the diagram. Place this box-shaped jacket 1 on the firebrick 5.
The bases of the gutter are formed by placing them facing each other, restricting their positions, and extending and arranging a large number of them in the longitudinal direction.
These box-shaped jackets 1 are embedded in a concave base preformed in the shape of a trough and are restrained from opening outward.

Pour the monolithic refractory 4 on top. The layer thickness of this monolithic refractory 4 may be approximately 200 to 400 mm. Note that the inner wall surface of the box-shaped jacket 1 above the upper surface of the monolithic refractory 4 is exposed and remains the metal surface of the raw material.

冷却水は給水ヘツダー２に入つて箱型ジヤケツト
１を通り排水ヘツダー３より排水されている状態
で樋内を溶滓７が流動していく。冷却水が通過す
ることにより箱型ジヤケツト１は冷却されている
のでこれによつて温度は高いが比熱の比較的低い
溶滓７は箱型ジヤケツト１との接触面において硬
化しコーテイング６を形成する。(Function) When using the gutter for transporting slag of the present invention, cooling water first enters the water supply header 2, passes through the box-shaped jacket 1, and is drained from the drainage header 3, while the slag 7 flows in the gutter. I will do it. Since the box-shaped jacket 1 is cooled by the cooling water passing through it, the molten slag 7, which has a high temperature but a relatively low specific heat, hardens at the contact surface with the box-shaped jacket 1 to form the coating 6. .
コーテイング６が形成されるまでは、箱型ジヤ
ケツト１と溶滓７の接触面は一時的に高温となる

役割りを果たし、箱型ジヤケツト１の熱負荷は低
減される。又コーテイング６は溶滓７による箱型
ジヤケツト１の摩耗を防止する効果も有する。 Until the coating 6 is formed, the contact surface between the box-shaped jacket 1 and the molten slag 7 is temporarily at a high temperature, but once the coating 6 is formed, it acts as a heat insulating layer and the heat of the box-shaped jacket 1 is absorbed. The load is reduced. The coating 6 also has the effect of preventing the box-shaped jacket 1 from being worn away by the molten slag 7.

The box-shaped jacket 1 has a height of 700 mm and a length of 2000 mm. Furthermore, the partition plate 8 was assembled by welding four 12 mm steel plates at appropriate intervals.
