Praise by users. Three hollow steel rolling process with a core drilling method ── hot-rolled, hot to wear - Heat pull method, thermal wear - hot rolling method, hollow steel surface contrast three processes produce macroscopic and microscopic quality, will use this Three processing technology H22-40SiMnCrNiMo Rod industrial assessment test results showed that: drilling with a core drill rod hot rolling wear life than hot - hot pull method, thermal wear - hot rolling method of brazing rod length, the existing Thermal wear - Heat pull method and thermal wear - Rod life hot rolling method is basically the same, but the failure modes and the longest life expectancy analysis, thermal wear - hot rolling heat wear - Hot Rod pull method for increasing life expectancy, potential big.
