Continuous Mesh Belt Type Austempering Furnace - ZAMS With high toughness and superior impact resistance, austempering process can be achieved continuously and automatically.

Equipment Overview
Generally, steel fasteners (springs, etc.) are heated up to around 850°C at 1atm and quenched in a 350-400°C salt bath to achieve continuous high toughness, high impact resistance, and minimal deformation treatment.
Treatment capacity of 50-200kg/hr.

Equipment Features
* Mesh belt type heating furnace with a regulator for zigzag belt movement.
* Optional automatic gauge and feeder
* Heating furnace coupling segment equipped with various devices and structures, such as a salt curtain to block salt vapor and atmosphere, and to prevent deformation and workpiece chute adhesion.
* Optional sludge separation tank salt quenchability tester (IVF QUENCHOTEST), and waste water disposal plant for total nitrogen regulatory compliance, etc.
*Non-hazardous salts which can be used with the above devices are also available.

ZAMS is a next generation austempering furnace, designed to save energy and labor, and reduce maintenance overhead. We are the sole manufacturer in Japan of industrial salts to be used in this equipment as well as the equipment itself.

applicable parts
Continuous ISO-Quenching System - CADIS Heat treatment for less deformation can be made by salt quenching. It is most suitable for gas carburizing of gears and ADI treatment of FCD materials.

Equipment Overview This system is capable of unmanned continuous operation using its tray batch style automatic carrier. It is also equipped with a salt quenching tank, which reduces thermal shock and produces treatment with far less distortion and deformation. ADI treatment of FCD materials is made possible by raising the temperature of salt up to approx. 400°C. Bainitic structures obtained using this treatment are exceptionally tough, with tensile strengths reaches of up to 100kgf/mm2.

Equipment Features
* Freely changeable atmospheric gas makes various types of heat treatment possible
* The system's preheating furnace makes effective and continuous operation possible
* Considerable reduction in gas heating energy costs
* High salt volume produces stable cooling performance


Application Examples
* Gas carburizing salt quenching (various types of gears and shafts)
* ADI (construction joints and various types of strut fittings)
