Product specifications for the Φ 5.5 ~ 20 mm, single reel weighs about 2.1 tons. The main products of the design quality carbon steel. The content of this workshop design mainly include: product outline and the formation of metal sheets; Design process and process flow; The determination of working system and the rolling mill production ability analysis; The main equipment choice; Selection and calculation of the auxiliary equipment; Workshop layout and lifting transportation; Workshop technical and economic indicators; Pass design; Rolling force can parameters calculation and motor equipment checking, etc. This design materials using continuous casting billet, in order to reduce the loss of metal, and the organizational structure of the continuous casting billet is better, it also improve the quality of the products; Also can reduce the gap of rolling time and improve productivity. As the walking beam type reheating furnace, heating furnace front-rear way using side in side out.Heating furnace is controlled by microcomputer, melt temperature is 1050 ~ 1250 ° C. Rolling mill and high-speed wire mill, across all is no twist rolling. Microstructure, to improve the product after rolling by adopting the technology of co
