linea di tempera e rinvenimento per nastri di acciaio ad alto tenore di carbonio

Hardening and tempering lines for steel strip with electric heating.

Prodction: 80 - 150 Kg / h

The plant is composed by a storage hopper, a screw barrel and a exhausted system.
The material to polish is put in the barrel by a vibrator storage hopper and after a programmable time is discharged with automatic inversion of
screw rotation in the container.
During the crossing in the screw barrel, the material is polished and separated from sawdust and scales trought an exauster cyclon and a special valve
connected to the barrel.
The scales are collected in a container and the sawdust are collected in a bag to be recycled.

CB300

Output: 300Kg / h - 12 Kw

CB1000

Output: 1000Kg / h - 30 Kw

COATINGS

material	hardness	roughness after grinding	thickness	anchoring strenght
chromium steel (Cr Mo )	HRC 48 - 58	0.1 - 0.5 Ra	3 - 8 mm	base material

This coating is used for thick har facing on wiredrawing machines' catheads.

Disadvantages: cracks can appear on pig iron base.

COATINGS IN TUNGSTEN CARBIDE

material	hardness	roughness after grinding	thickness	anchoring strenght
tungsten carbide + C-kind stellite	HRC 62 - 74	0.09 - 0.1 Ra	0.3 - 2 mm	base material

This facing is used for wiredrawers cones and rings; it's compact and not porous as it's (casting). It's an excellent facing for valve seats, shafts for rotating pumps, endless screws, plastic extrusion machines.

Disadvantages: the components has to be warmed up till 850 °C, so can be affected by distortion.

Advantages: water-proof and impermeable with materials that are not corrosive for cromel and tungsten carbide.

COATINGS (FLAMMIZZATI)

material	hardness	roughness after grinding	thickness	anchoring strengt
all metallic materials	various	various	0.3 - 10 mm	12 Kg/mm2

This coating is used for regenerating weared bushings' fittings, shaft-pumps or hard-packing for aluminium, stainless steel, plastics.

Disadvantages: facings are microporous.

Advantages: the material to be coated won't have any variation for >2 mm thicknesses.

CERAMIC COATINGS

materiae	hardness	roughness Rms	thickness	anchoring strenght	density
CrO2	Rn15=93 - 95	6 - 10	0.3 - 1.5 mm	2000 psi	3.2
Al2O3	Rn15=90 - 94	12 - 14	0.3 - 1 mm	2200 psi	3.7
COSIDE	Rn15=92 - 96	6 - 1	0.3 - 2 mm	2200 psi	3.9

CrO2 facings are more lasting and abrasion-resistant. For safety reasons, as CrO2 at the sublimation temperature makes (esavalente) chrome, extremely toxic and carcinogenic, during the (plasmatura), is replaced by Tentorio with a blend of inert oxide refractory "COSIDE", a bit harder but less thick than CrO2.
The basic blends of Al2O3 and TiO2 are used for txtile machines' components with good resulti, lower than CrO2 and "COSIDE".

Disadvantages: facings are micro-porous, in presence of water or compounds the inner base can oxidize or change composition although the phenolic sealing.
Basi\es in AISI 316 o AISI 304 are adviced.
