Hot Strip Mill shearing Knives
jinyu Hot Strip Mill shearing Knives crop the head and tail ends, or divide and cut-to-length continuously cast shapes whether slab, thin slab, strip, billet, bloom, or bar. They also remove the dross or beard that develops on the edge of continuously cast slabs. They are used between the caster delivery section and the first rolling mill stand, tunnel, or re-heat furnace. They typically operate at temperatures in excess of 1800s/1000 and may be used without or with indirect coolant.
Shearing Blades
