To be more economical and convenient, the demand for non-standard specifications of wire rod increases. 2. The single roll weight of wire rod is expected to increase on the basis of the current. 3. The demand for high-quality steel and alloy steel has increased significantly. As the mainstream wire rod mill type in domestic wire rod production, the design product outline of high-speed wire rod mill is generally finished product 5.5mm-20mm with 0.5mm increment smooth wire rod. In order to meet the progress of wire rod deep processing technology and the expansion of deep processing products of downstream metal product enterprises, the market demand for Φ17.3mm specification wire rod is large, and many wire rod mills are limited by equipment level and process design and cannot produce. To meet the individual needs of users, Φ17.3mm specification needs to be designed and produced, which not only broadens the product outline, but also reserves technical capability. When developing Φ17.3mm specification products for high-speed wire rod mill, the design of finished product frame ring and pass is a key link. The finished product frame ring and pass rotate at high speed with the rolled piece in production, which plays a role in rolling deformation to standard shape for the rolled piece. The rationality of the design of pass width, depth and curvature related parameters is the key to ensure smooth production.
[0003] Especially, the stability is poor because the roll ring is easy to rotate with the shaft during use. Therefore, the utility model provides a high-speed wire rod finish rolling mill finished product ring to solve the above problems. UTILITY MODEL CONTENTS
