軋輥設備生產詢問報價

軋輥由輥身、輥頸和軸頭二部分組成。輥頸安裝在軸承中，并通過袖承座和壓下裝置把軋制力傳給機架。鉑頭和連接軸相連接，傳遞軋制扭矩。軸頭有三種主要形式；梅花軸頭、萬向軸頭、帶鍵槽的或圓柱形軸頭。

The roll is  of two parts of the roller body, the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum, a universal shaft, or a cylindrical shaft with a keyway.

19世紀下半葉歐洲煉鋼技術的進步要求軋制更大噸位的鋼錠，無論是灰鑄鐵或冷硬鑄鐵軋輥的強度均已不能滿足要求。含碳量為0.4%～0.6%普通鑄鋼軋輥相應誕生。重型鍛壓設備的出現更使這種成分的鍛造軋輥的強韌性得到進一步提高。

In the second half of the nineteenth Century, the progress of steelmaking technology in Europe requires larger tonnage steel ingots to be rolled. Neither the strength of gray iron or chilled cast iron rolls can meet the requirements. The ordinary cast steel roll with a carbon content of 0.4% to 0.6% is born accordingly. The emergence of heavy forging equipment makes the strength and toughness of the forging roll of this component further improved.

通常對粗軋輥以強度、抗熱裂為主要要求；小型20輥軋機的工作軋輥重僅 100克左右，而寬厚板軋機的支承輥重量已超過200噸。選用軋輥時首先根據軋機對軋輥的基本強度要求，選定安全承載的主體材料（各種級別的鑄鐵、鑄鋼或鍛鋼等）。

Usually, the main requirements for rough rolling roll are strength and thermal cracking. The working roll weight of small 20 high mill is only 100 grams, while the weight of backup roll of wide plate mill has exceeded 200 t. When selecting the roll, first, according to the requirements of the mill's basic strength for the roller, we select the main material for safety loading (various grades of cast iron, cast steel or forged steel, etc.).

當軋制其它型材時，可以用水平機架更換機架。水平機架的軋輥有很深的孔型，而機架沒有。  

較大直徑的水平軋輥確定型鋼的的形狀，而較小直徑的一對立輥用于軋制邊部。當坯料穿過傳統機架和機架精軋軋輥時，可以獲得很好的表面光潔度和尺寸公差。  

When rolling other profiles, the universal rack can be replaced with a horizontal rack. The roll of the horizontal frame has a very deep pass, but the universal rack does not.

Horizontal rolls with larger diameters determine the shape of the section steel, and a pair of rolls with smaller diameters are used for rolling edges. Good surface finish and dimensional tolerance can be obtained when the blank passes through the conventional stand and universal stand finish rolls.
