Drawing Furnaces

• indirectly electrically heated
• as continuously operating plants for hardening and tempering of bimetal saw bands, knife blades, razor blades, technical blades, surgical blades etc.

Drawing Furnace Hardening Plant with Protective Gas Operation

• e. g. for hardening and tempering of band steel, technical blades, saw bands
• continuous process
• hardening up to 1,230 °C
• tempering up to 650 °C

New Development:
“Static Cooling Track for Bimetal Saw Band Hardening Plant”

The new ”cooling track” developed by RUHSTRAT works more effectively than the present methods of quenching and cooling saw bands and it provides many advantages for you:

• cost saving due to lower energy consumption – omission of cooling agent and cooling machine
• environmentally friendly thanks to omission of the cooling agent – only cooling water is used for cooling
• reduction of the susceptibility to interference and low wear and tear – thanks to the omission of the cooling machine with rotating components
• operation, service and maintenance of the ”cooling track” are facilitated
