優(yōu)化水量,優(yōu)化步距。盡可能的使型鋼完整進入水區(qū),加強現(xiàn)場通風(fēng),保證型鋼進入水區(qū)前溫度小于400℃。水冷時間不宜過長,因為冷卻時翼緣為拉伸—壓縮—拉伸過程.

Optimize the amount of water and optimize the step distance. As far , the steel can be fully entered into the water area, and the field ventilation is strengthened. The temperature of the steel before entering the water area is less than 400. The time of water cooling should not be too long, because the flange of the wing is stretched, compressed and stretched.


明確軸向位置,加大矯直壓力。不要單獨打8輥軸向,調(diào)整側(cè)彎時應(yīng)以每相臨的3個輥為一個調(diào)整單元,保證矯直穩(wěn)定性。側(cè)壁斜度的處理措施是經(jīng)常注意檢查各輥軸向位置,竄動情況。帶潛行裝置的拉鋼式冷床很大優(yōu)點足冷床床面利用率可達60%,可以自由地儲存軋件,機動性能較好。注意在不同間隙情況下,矯直力的選取。對H2與H3的測量做到每批抽查,以做到及時調(diào)整。



The axial  is clearly defined and the straightening pressure is increased. Do not play the 8 roll axis alone. When adjusting the side bend, 3 rolls per phase should be used as an adjustment unit to ensure the straightening stability. The treatment of side wall slope is to check the axial  and movement of each roll. Pay attention to the selection of maximum straightening force under different clearance conditi. The measurement of H2 and H3 is done in each batch, so as to adjust it in time.


中型軋鋼車間生產(chǎn)的各種鋼材,經(jīng)軋鋼機軋制后由熱鋸機(或剪切機),切成定尺長度,還需要冷卻到常溫,再進行矯直。軋制后的熱軋件冷卻時,由于連續(xù)生產(chǎn),一般都是在緩慢的橫向移動過程中逐漸冷卻的。這種使軋件橫向移動并冷卻的設(shè)備,叫做冷床。



All kinds of steel produced in medium rolling mill are cut by hot saw (or shearing machine) after rolling mill, and it is cut into length of fixed length. It also needs to be cooled to normal temperature and then straightened. After rolling, the hot rolled parts are cooled down gradually because of continuous production. The equipment for rolling and cooling the workpiece is called cold bed.


拉鋼式和往復(fù)多爪推齒式兩種冷床對于圓鋼都不太適用,容易拉斜、滾亂。冷卻圓鋼(管坯)以使用鏈式冷床較好,上鋼一廠、大連鋼廠的650軋鋼車間都采用鏈式冷床,兩者所不同之處在于:上鋼一廠的圓鋼擱在臺架上,鏈條拉著圓鋼緩慢前進,由于圓鋼單重較大,一般不會亂滾。大連鋼廠的圓鋼直接擱在鏈條上,前進過程中圓鋼與鏈條無相對運動。oftenstraighteningandfinishedplatefilletfillet。兩種鏈式冷床使用單位反映都較好。



The two kinds of cooling beds, pulling steel type and reciprocating multi tooth type, are not very suitable for round steel. Cooling round steel (Guan Pi) to use the chain type cold bed is better, the 650 steel mill of Shanghai steel factory and Dalian steel mill use chain cold bed. The difference lies in that the round steel in the first steel plant is on the bench, the chain pulls the round steel slowly forward, because the single weight of the round steel is larger, it will not roll out. The round steel of Dalian steel plant is directly placed on the chain, and there is no relative movement between round steel and chain during the progress. The use unit of the two types of chain cold beds is better.
