Cold-rolled ribbed steel production equipment: cold-rolled ribbed steel production equipment based on the number of rolls in two and three-roll-shaped roll shape. Three-roll mill Passive: Passive three-roll mill is currently the largest domestic application of a cold rolling mill steel wire rod imported from overseas mills are mostly belong to this category. In this mill, each consisting of three rolls by, was Ah-type layout, its angle of 120 ° 9.5mm cold-rolled steel wire rod price, composed by this mill production line. Cold-rolled ribbed steel structure design points: fatigue stress amplitude limit. Steel plate for class members under fatigue loads Buying 9.5mm cold-rolled steel wire rod, when the maximum stress fatigue checking does not exceed 300N / ram2, fatigue stress ratio is not greater than 0.3, the fatigue stress amplitude steel should not exceed 120N / ram2. Concrete strength selection. For reinforced concrete structures in a class environment, the concrete strength grade of not less than C20. 9.5mm cold-rolled steel wire rod price _ _ Dingding cold rolled steel cold-rolled rod is provided by Ding Ding Industrial Co., Ltd., Henan Province.
