冷軋三級鋼生產線 Cold-rolled three-stage steel production line
冷軋機是將Ⅰ級熱軋Q235圓鋼經冷軋、冷軋軋制出成品形似螺旋狀的鋼筋的機器設備。冷軋機設備在軋制冷軋帶肋鋼筋的過程中可對母材的經緯方向同時進行冷加工，在保留原截面*區(qū)域品體的相對平衡和穩(wěn)定的前提下，在提高抗位、抗壓的同時，仍保留足夠的延伸性能，從而使得幾何參數(shù)(軋扁厚度、截面寬厚比，面縮率和節(jié)距)和四項材質指標(抗拉強度，條件屈服值，伸長率和冷彎)可用于甲等*等級的重要工業(yè)與民用建筑，節(jié)約用鋼量，降低建筑價格。
冷軋螺紋鋼軋機采用五輪珞鋼除磷，除磷效果透徹。雙軋工藝，副軋機與主軋機均采用主動式同步工藝鉆石合金軋輥。 軋輥選用國內質量較好的株洲601鉆石牌硬質合金。成品鋼筋達到高延性冷軋帶肋鋼筋鋼筋標準和GB13788-2008標準。軋輥損耗：按鋼筋型號單槽生產：Φ6/1000T、Φ8/1200T、Φ10/3000T、Φ12/4000T、Φ14/6000T。自主研發(fā)雙井式收線機，可自動切換無需停機，三面冷軋帶肋鋼筋機，收卷外觀及性能和三級鋼盤螺相同。
延性冷軋帶肋鋼筋生產線是將Q235、Q215、Q195熱軋盤園鋼筋經冷軋、表面形成二面帶有月牙的帶肋鋼筋，經研究國內外冷軋工藝裝備的長處與不足，高延性冷軋帶肋方案，成功研制二面肋冷軋帶肋鋼筋生產線，新型冷軋帶肋軋機，透徹解決了長期困擾冷軋帶肋鋼筋延伸率不達標的難題。冷軋兩肋螺紋鋼筋加熱生產線產品可節(jié)約三級鋼中的貴重金屬V釩、Nb鈮、Ti鈦，該機組操作方便，更換不同的鋼筋不需要更換軋輥，機器制作簡單調整，浙江冷軋帶肋，不用潤換粉、冷卻液，生產成本低，是一套直條生產線，也可配收線機收卷。
Cold rolling machine is a machine and equipment for cold rolling grade I hot rolled Q235 round steel to produce the finished steel bar in the shape of spiral. Cold rolling machine can cold process the warp and weft direction of the base metal at the same time in the process of cold rolling ribbed steel bar. Under the premise of preserving the relative balance and stability of the body in the central area of the original section, while improving the position resistance and compression resistance, it still retains enough extensibility, so that the geometric parameters (rolling thickness, section width-thickness ratio, Surface shrinkage and pitch) and four material indexes (tensile strength, conditional yield value, elongation and cold bending) can be used for important industrial and civil buildings of class A safety grade, saving the amount of steel, reducing the construction price.
The cold rolled spiral steel mill uses five rounds of Luosteel to remove phosphorus, and the phosphorus removal effect is thorough. Double rolling process, secondary mill and main mill adopt active synchronous diamond alloy roll. Roller selection of domestic quality Zhuzhou 601 diamond brand hard alloy. The finished steel bar meets the high ductility cold rolled ribbed steel bar standard and GB13788-2008 standard. Roll loss: according to the steel bar type single slot production: Φ6/1000T, Φ8/1200T, Φ10/3000T, Φ12/4000T, Φ14/6000T. Independently developed double well winding machine, can automatically switch without stopping, three side cold rolling ribbed steel bar machine, winding appearance and performance is the same as three level steel coil screw.
Ductile cold rolled ribbed steel production line is to cold-rolled Q235, Q215, Q195 hot rolled coil steel bar, the surface of the ribbed steel bar with two sides with crescent. After studying the advantages and disadvantages of cold rolling process equipment at home and abroad, high ductibility cold rolled ribbed steel production line with two sides of cold rolled ribbed steel bar, a new cold rolled ribbed steel mill, The problem that the elongation of cold rolled ribbed steel bar is not up to standard has been thoroughly solved. Cold rolled two ribbed thread steel heating production line products can save the precious metal V vanadium, Nb Nb, Ti titanium in three steel, the unit is convenient to operate, the replacement of different reinforcing bars do not need to replace the roll, the machine is simple to adjust, Zhejiang cold rolling rib, no need to run the powder, coolant, low production cost, is a set of straight line production line, can also be matched with line winding machine.
