ブ１からの放熱量の低減をはかつていた。[Prior Art] In steel rolling equipment, a slab coming out of a heating furnace or the like is transported by a transport line and charged into a hot mill, but generally the length of the transport line is
Since it reaches 80 to 100 m, if the slab is exposed to the atmosphere during this period, the temperature of the slab will decrease due to heat radiation. In order to prevent such a temperature drop in the slab, conventionally, as shown in FIG. It used to be possible to reduce the amount of heat dissipated.
（特開昭60−17015号公報）
［考案が解決しようとする問題点］
上記のような保温カバーは、セラミツクフアイ
バー等のような耐火物から構成されているため、
保温カバー自体がスラブによつて加熱され、所定
の温度に保持されて搬送されるスラブの放熱量の
低減をはかつている。 (Unexamined Japanese Patent Publication No. 17015/1983) [Problems to be solved by the invention] Since the above-mentioned heat insulation cover is made of a refractory material such as ceramic fiber,
The heat insulating cover itself is heated by the slab, and is maintained at a predetermined temperature to reduce the amount of heat radiated from the transported slab.
しかしながら、耐火物からなる保温カバー自体

のに対し、スラブは加熱炉等から断続的にしかも
高速度でホツトミルに搬送されるため、スラブが
搬送ライン上を通過しても保温カバーは充分に昇

られないので、加熱炉においてスラブを必要以上
に加熱しなければならず、省エネルギー上も問題
であつた。 However, while it takes a relatively long time for the heat insulating cover itself made of refractories to reach a predetermined temperature, the slab is transported from a heating furnace etc. to the hot mill intermittently and at high speed. Even when it passes over the line, the temperature of the insulation cover does not rise sufficiently, and therefore the slab cannot be effectively insulated, so the slab must be heated more than necessary in the heating furnace, which reduces energy consumption. was also a problem.
また、耐火物からなる保温カバーは、温度の変
化によつて伸縮して亀裂や脱落を生じ、あるいは
経年使用により劣化するため、保守や改修に多額
の費用を要する等の問題があつた。 In addition, heat insulating covers made of refractory material expand and contract with changes in temperature, causing cracks and falling off, or deteriorate over time, resulting in problems such as requiring a large amount of cost for maintenance and repair.
さらに、保温カバーを搬送ローラの下方に設け
た場合、搬送ローラ上を通過するスラブから落下
したスケールが保温カバー上に堆積し、保温効果
が低下する等、多くの問題があつた。 Further, when the heat insulating cover is provided below the conveying roller, there are many problems such as scales that have fallen from the slab passing over the conveying roller are deposited on the heat insulating cover, reducing the heat retaining effect.

延設備におけるスラブの保温装置である。[Means for Solving the Problems] The present invention was made to solve the above problems, and includes a stainless steel plate, which is a clad steel plate consisting of an ordinary steel plate and a stainless steel plate, in the slab conveying line on the hot mill entrance side. A heat insulating cover with chrome plating on the side is arranged at least below the conveyance roller of the slab conveyance line with the chrome plating side facing inward, one end of the heat insulating cover provided below is fixed to the shaft, and the heat insulating cover is rotated. This is a slab heat retention device in rolling equipment that is movably installed.

増大することを知見した。[Function] The present inventor believes that in the case of conventional heat insulation covers such as ceramic fibers, it is difficult to raise the temperature, and hardly any heat retention effect due to radiant heat can be expected. On the contrary,
A heat insulating cover with chrome plating applied to the stainless steel plate side of a clad steel plate consisting of an ordinary steel plate and a stainless steel plate is placed at least below the conveyance roller of the slab conveyance line, with the chrome plated surface facing inside, and one end of the heat insulating cover is attached to the shaft. It has been found that when the heat insulating cover is rotatably provided, the heat insulating effect due to reflected heat increases.

である。 Therefore, the present invention reflects the heat radiated from the slab on the heat insulation cover, reduces the amount of heat radiated from the slab conveyed on the conveyance line, and also reflects the scale that has fallen from the slab passing on the conveyance roller onto the heat insulation cover. It is possible to improve the heat retention effect without depositing it on the surface.

The heat insulating covers 3 and 3a are made of a common steel plate as a base material, a stainless steel clad steel plate with a stainless steel plate crimped onto the surface thereof, with the stainless steel plate side facing inside, both sides bent downward and chrome plating applied to the inner surface. be.

本実施例における保温カバー３の厚さは６mmであ
つた。 The heat insulation covers 3 and 3a configured in this way are
Since the heat radiated from the slab 1 is reflected on its inner surface (reflectance of about 85%) and the slab 1 is kept warm by the reflected heat, there is no need to maintain the heat insulation cover itself at a high temperature. Therefore, the slab 1 that is transported intermittently and at a high speed can be kept warm with high efficiency. In addition,
The thickness of the heat insulating cover 3 in this example was 6 mm.
第３図は保温カバー３ａを搬送ローラ２の下方

果が低下する。 As shown in the heat insulating cover installation diagrams in FIGS. 2 and 3, when the heat insulating cover 3a is provided at least below the conveying roller 2 (or between the conveying rollers), the heat insulating cover 3a is installed at least below the conveying roller 2 (or between the conveying rollers). Scale 5 accumulates on the heat insulation cover 3a, and as shown in FIG. 5, the heat retention effect decreases in accordance with the amount of scale 5 accumulated.
このような問題に対処するため、第４図に示す

動させるようにしてもよい。 Thereby, the heat insulating cover 3a is rotated as shown by the broken line, and the scale 5 is dropped, thereby preventing the heat insulating effect from decreasing. Such heat retaining covers 3a may be rotated individually, but since several dozen transport rollers 2 of the slab 1 are arranged, for example, each heat retaining cover 3a is connected to one lever, and this The levers may be actuated by an air cylinder or the like to rotate all the heat insulation covers 3a at the same time.

い。 In the above explanation, a heat insulating cover is provided on the conveyor line from the outlet of the slab heating furnace to the inlet of the hot mill. It goes without saying that the present invention can also be applied to the conveyance line from the outlet of the hot mill to the hot mill.

果が大である。[Effects of the invention] As is clear from the above explanation, the slab heat insulation device in the rolling equipment of the present invention consists of a normal steel plate and a stainless steel plate, and the heat insulation cover is made of a clad steel plate with chrome plating on the stainless steel plate side. Therefore, most of the radiant heat from the slab is reflected by the insulation cover, making it possible to efficiently insulate the slab that is being transported at high speed intermittently on the conveying line, thereby reducing the energy used to heat the slab. You can save money. In addition, there is no risk of deformation or deterioration even after long-term use, and it can be used semi-permanently, so equipment and maintenance costs can be significantly reduced. Since it is configured to be rotatable,
By removing the scale that accumulates on the heat insulation cover, it is possible to prevent a decrease in heat retention, and the effects of implementation are significant.
