Success in Cold rolling strip threading through continuous annealing unit

In June 5th, the four section of tie steel 1550 cold rolling mill, which was built by China twenty Metallurgical Group, was successful in strip threading process, 2 days ahead of schedule.

Since October 2016 Continuous annealing set the installation of equipment , the total weight of installation of equipment is 4100 tons, a total of 800 km cable laying, total 250 tons of column and the unit medium pipe, 500 tons of flue pipe. Which even the furnace is long and high, complex equipment,installation is difficult, and other regional installation tasks intensive and heavy. In the process, the project department optimized the construction, co-ordination arrangements, meticulously planned, high quality and efficient completion of the construction tasks, during the peak of construction period， the staff reached 300 people.

During strip threading, the steel through more than 435 meters long units, from the entrance, through cleaning section, entrance looper, cleaning section, annealing furnace, export loop, flat machine, check the loop, outlet area to a coiling machine end. Among them the annealing furnace is 28.6 meters high, 3 Sets are 32.2 meters high, the construction is very difficult. Under the high temperature of more than 30 degrees, China twenty Metallurgical Group construction personnel to actively cooperate with the owners according to plan and ordered wearing a success, the construction personnel professionalism and skill won the party and the supervision of praise.
