The side guide is also called guide, which is an important part of the hot rolling production line and is used to ensure the stability and directionality of the hot-rolled strip during traveling (especially before coiling), generally, there is a group or many groups of side guides. During operation of the hot rolling unit, the high-temperature and high-speed hot-rolled sheet contacts and rubs with the side guide, which results in are serious wear of the contact part and cause such quality problems as burrs and scratch on the edge of the hot-rolled sheet. The wear loss of the side guide made of conventional carbon steel is 10-15mm a day, which results in replacement and repair of the side guide of the hot rolling unit every day.

The amorphous composite ceramic coating fabricated by our company with advanced plasma cladding technology has excellent normal temperature hardness and high temperature hardness, meanwhile, with optimized chemical composition of the material, the friction coefficient is effectively reduced and the wear-resisting property of the material is greatly improved. The product is characterized by domestic-leading and international-advanced technology, and the side guide manufactured has a service life of up to 5-7 days.

Excellent cost performance

• Reduce the workload at the production site

Replacement made once a day is improved to once every 5-7 days, the workload for replacement of the maintenance personnel is reduced and repair welding is eliminated; the site is released and the amount of spare parts for the side guide is reduced. 

• Reducing wear and improving product quality

The groove depth of long-life side guide decreases after wear, reducing the damage to the hot rolling strip and improve the quality of the hot rolling strip product.The wearing depth of carbon steel side guide is more than 5 mm per day, and can even reach 10-15 mm.The total wearing depth of side guides adopted with new technology can be reduced to 1 mm per day.

• Improving the output of hot rolling production line 

The reduction of replacement frequency is beneficial to the increase of field production. If the service life of side guide is increased from 1 day to 5 days, the production time of the hot rolling production line may be increased by 8 hours every month. Taking the 1780 hot rolling production line as an example, at least 1,000 tons of hot-rolled sheets may be increased per year.
