Amount requires to be increasingly stringenter, and common practice is to improve plate shape by smooth process in finishing at present.Leveling roll is that control changes
The final step of kind hot-rolled product is directly related to product quality, therefore also corresponding very high to leveling roll roll surface quality requirement.Now by
The use cost of the limitation of service life, leveling roll is high, and production efficiency is low, so promoting roller surface hardening technology, extension makes
With the period, reduce use cost, improve production efficiency the emphasis for being current propulsion and studying.
The service load of hot rolling and leveling machine leveling roll is respectively 1200,1700,1360 tons of (2050,1880,1580 areas
Domain), impulsive contact force is up to 200kg in work, and since the shock and frictional force with steel plate are all very big, leveling roll often occurs
Abrasion, pit and dry slag etc. destroy.Again since the quality requirement to steel plate is very high, to the roll surface quality requirement of leveling roll also phase
Should be very high, as roll surface roughness difference to reach respectively with rack by region 0.2-0.4,0.8,1.0-2.0 (2050,1880,
1580 regions) etc., abrasion is not less than 0.3mm, the average roll change period is respectively 600 tons, 2000 tons, 3000 tons (1580,1880,
2050 regions) therefore leveling roll roll change frequency it is very high.And if scratch, de- block or plucking occurs in surface of steel plate, just in production
Roll change is shut down, going on smoothly for production has been seriously affected.
