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-shaped, two-roll mill out of the product are two sides of the ribs, and easily confused with the hot-rolled steel cold rolling 9mm steel wire rod mill, now less used; three-roll products are on three sides of ribs, more than 90% of the mill are three-roll mill. It is consistent with the foreign standards. Three-roll mill by traction distinguish 9mm steel cold rolled wire rod sales, can be divided into two kinds of passive and active. Design features rolled ribbed steel structure: tensile (compressive) strength selection. According to "cold-rolled ribbed steel Technical specification for concrete structures" in the reinforced concrete structure 9mm cold-rolled steel wire rod prices for general configuration, CRB550 grade steel tensile, compressive strength design value of 360N / mm; for the axis tension and small eccentric tension member of cold-rolled ribbed steel design value is greater than the tensile strength 300N / ram2, should 300N / tom2 adoption. 9mm cold-rolled steel wire rod mill, cold rolling Ding Ding, 9mm cold-rolled steel wire rod by Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In cold-Ding Ding leadership with the staff warmly welcome all inquiries negotiations to create a better future for cold-Ding Ding.
