Description of the invention (The present invention relates to a coil box furnace which has a heating device for reheating the coil to the rolling temperature and a saddle for containing the coil to be reheated. The tropical material is produced at the best cost Peripheral equipment is gradually required to reduce defective products. These include more specific equipment, which can be re-introduced into the processing line to continue production and eliminate errors if the strip initially processed on the processing line has errors. The coil box at the entrance allows the initial strip to be coiled and polished for about 10 minutes and then used in the case of mild steel. However, these reserved properties are not owned by high-grade steel, such as stainless steel, and high-grade steel can only be rolled at extremely narrow temperatures. Therefore, if the error lasts for several minutes, the strip is initially deposited into coils, but it was not possible to introduce coils into the rolling line in the past. Using reheating furnaces on coil boxes can provide a remedy. The coil box furnace makes any The coil strip is initially heated to the rolling temperature and integrated into the rolling process again. The coil coil furnace, which is known in practice, is configured as a cavity with a fixed and movable tank portion. Form of melting furnace. The movable box is electrically driven and can be moved on the road by wheels. The melting furnace is heated by zigzag heating conductors. The conductors are installed on the four side walls of the melting furnace and are combined into individual control groups. After additional heating and in the form of a circular section, it is erected on the refractory concrete floor and heat-resistant steel frame (refer to Figure 1). However, in the coil box melting furnace of the prior art, the initial strip measurement during the re-introduction rolling process Significant regular changes in the temperature are found, which adversely affects the rolling performance such as the finishing line and the tolerances achieved by the final rolling thickness. -4-The size of the wood paper is applicable to China National Standard (CNS) A4 (210X297 mm) ) ^ Installed ----- one order, ------ (Please read the notes on the back before filling out this page) Printed by the Ministry of Economic Affairs, Intellectual Property / i Bureau, Industrial and Industrial Consumer Cooperation Fi 490491 A7 _ ____ B7_ V. Description of the invention (2) The purpose of the present invention is to improve the coil box furnace so that the coils temporarily stored therein can be uniformly heated to the rolling temperature as much as possible, thus reducing the number of strips rolled after finishing. The final temperature tolerance for temperature conditioning is minimized. To solve this problem, according to the present invention, at least two bearing surfaces of the saddle can bear the tangent direction of the coil at its outer periphery. The saddle is preferably configured as a trapezoid. The solution provided by the present invention is based on the prior art coil box furnace. The cyclical change in the temperature of the strip taken out is mainly due to the fact that the furnace coil and the saddle are in the form of round segments. The arc-shaped saddle can remove the thermal energy from the strip by a relatively wide area of radial heat conduction. Periodic temperature changes. On the contrary, in the coil box furnace according to the present invention, the size of the load-bearing section containing the saddle is reduced, and with the decrease of the perceivable heat loss, the rolling performance of the finishing line and the rolled strip after finishing The thickness tolerance of the material is relatively improved. In the preferred embodiment of the present invention, the bearing surface is formed by the plurality of bumps spaced in the width direction of the coil. This further reduces the actual contact area between the saddle and the coil. At the same time, the preferred saddle is made of high-grade flat steel with interactive meshing, especially stainless steel flat steel with raised bumps. In contrast to the aforementioned circular segment saddle of the prior art, it is not necessary to use a refractory material to stably accommodate the saddle according to the present invention. It is also preferred that according to another feature of the present invention, a heating device is also provided on the side wall of the furnace for accommodating the saddle. Preferably use induction saddle heating. According to yet another advantage of the present invention, the saddle also has a dress for rotating or swinging the coil. This configuration makes it possible to uniformize the temperature profile of the preliminary strip re-introduced into the finishing line. -5-Apparel and paper scales are applicable to China National Standards (CNS) M specifications (21〇 > < 297 Gongguang) ^ ----- 1— (Please read the notes on the back before filling this page) Order- # Printed by the Consumer Cooperatives of the 4th Bureau of Wisdom and Finance of the Ministry of Economic Affairs
