Furnace Rolls for thin Slab Caster RHF

タイトルまたは説明

Re-heating Furnace Rolls, life 5 years!
1.Re-heating Furnace Rolls for Slab Caster and for Si Steel Hot rolling

1. We developed a new Ni-Cr-W alloy for Re-heating furnace rolls, it’s melting temperature is ********0 Degree C, which is about **0 Degree C higher than normal heat resistance alloy.
2. The New generation of CamZone furnace rolls made from this new alloy, can work at ***0 degree C. CamZone furnace rolls have a higher wear resistance (less than 2.8 mm wear out in 3.5 years). These two technical advantages can reach the requests of Si Steel hot rolling.  
3. Application and installation

1. Spindle made by cold drawn seamless pipe, Rings made by CamZone new Ni-Cr-W Special alloy casting, with resistance to high temperature, to wearable, to impact of moving slab.
2. High temperature resistance: up to ***0 C, CamZone Furnace Rolls can accept higher furnace temperature for Si Steel.
3. Life: less than 2.8 mm wear out in 3.5 years, Clients can decrease the replacement of rolls.

1. Client’s purchasing Plan, connected to CamZone’s production plan.
2. Client’s life database
3. Client’s un-normal Life alarm
4. Site Installation process, site condition request, installation know-how for long life,
5. Off-line conditions: *2 mm ware out (WuHan Steel Co, CSP)

1. WuHan Steel Co
   1. Caster and HSM builder: SMS – Demag CSP
   2. Furnace builder: Techint Italy
   3. Steel Grade: mix of Silicon Steel and carbon steel
   4. Life comparison:

1. TongHua Steel Co, Danieli Caster, Bricmont Reheating furnace
   1. 1 Caster 2 strands supplied by Danieli, Reheating furnace supplied by Bricmont. Width ***0 mm, thickness *0 – *0 mm. Products: X*0, SS**0, Q**5B, SPHC. Yearly production: 2.5 M TPY.
   2. Since ***6, CamZone has been supplying Furnace Rolls to Reheating Furnace of CSP of TongHua Steel Co, average life *6 months.
   3. Since ***9, CamZonesupply by “pay by production tons”, decrease the Cost to 1 USD/production ton.
