【発明の詳細な説明】
本発明は動いている金属製品、特に縦列進行している金
属製品の冷却方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cooling moving metal products, particularly metal products traveling in tandem.
本発明は圧延機の出口における金剛製品、たとえば鋼板
１形鋼またはレールに特に適用されるが、またブルーム
またはビレットのような連続した鋳造製品にも適用され
る。The invention applies in particular to rigid products at the exit of a rolling mill, such as sheet steel sections or rails, but also to continuous cast products such as blooms or billets.
これら鋳造または圧延製品の冷却の問題は常に特別な注
意を引く課題であった。何故ならそれは先ず第一に製品
の構造の均整性または時間の経過によるその均整な進展
を決定するからである。The problem of cooling these cast or rolled products has always been a subject that has received special attention. This is because it first of all determines the symmetry of the structure of the product or its uniform evolution over time.
この見地においてこの冷却を確実にする最もよく用いら
れる手段の一つは、縦列進行する製品の上に、空気、水
、水蒸気のような適当な冷却剤の噴流を、適当な装置を
用いて単独にまたは互いに混合してまたは霧状にして注
ぐことである。One of the most commonly used means of ensuring this cooling in this respect is to apply a jet of a suitable coolant, such as air, water or steam, over the product traveling in tandem, using suitable equipment. to pour into or mixed with each other or atomized.
本出願者はそのベルギーＷＮ第８５１３８１号において
−この種の製品の冷却を確実に行なうための一つの装置
をすでに提案した０それは空気で霧状にされた水を噴流
の形で製品の上に注ぐものである。The applicant has already proposed in his Belgian WN No. 851 381 - a device for ensuring the cooling of products of this kind, in which water atomized with air is poured onto the product in the form of a jet. It is something to pour.
この装置は所望の冷却を満足に行なうことができるが、
冷却すべき製品の幅が大きくなるに従っである権の不都
合が生ずる。Although this device can satisfactorily perform the desired cooling,
Certain disadvantages arise as the range of products to be cooled increases.
先ず第一に、その装置を用いると圧縮空気の大きな容積
が必要となり、そのため幅の広い製品には操業費が著し
く高くなる。First of all, the equipment requires large volumes of compressed air, which makes operating costs significantly higher for wide products.
その上、長さの大きい装置の中で空気と冷却水の流量の
均一な配分を確実にしかつ維持することは、装入量の損
失の差異のため、困難である。Moreover, it is difficult to ensure and maintain a uniform distribution of air and cooling water flow rates in large length equipment due to differences in charge losses.
本発明はこれらの不都合を矯正することを目的とする。The present invention aims to correct these disadvantages.
