Product Description
Long Bar Induction Heat Treatment Machine
Application: Continuous hardening and tempering
Part: long bar, threaded rod
Size: 6-100mm
Length: 1000-14000
Grade: 8.8, 10.9, 12.9
Material: Carbon steel, alloy steel
Long bar heat Treating is induction heating for Quench and Tempered Bars. Heat treatments available by heat treating line are Quench and Temper, Stress Relieving, Thru Hardening, Surface Hardening.
Feature
Okay for small &big production capacity as threaded rod heated continuous one by one, and also the machine can start &stop work by only press a bottom
• The quality of finished product highly improved as single pieces continuous faster heating to avoid seriously oxidation &decarbonization (carbon lost along with heating)
• Power and water can support the running of whole system , no pollution, good for environment
• Hardening, tempering, surface finishing (to avoid oxidation) can be finished in one production line
Duolin long bar heat treating line can process bar size from 6-100mm, length from 1000-14000, meet small & big production capacity.
Application: Continuous hardening and tempering
Length: 1000-14000
