Product Introduction

The furnace ZY-XA-27 as shown in the figure integrates the control system and the furnace chamber. The furnace lining is made of vacuum-formed high-purity alumina lightweight material.

The control panel is equipped with an intelligent temperature regulator, a power switch, a main heating start/stop button, voltage and ammeters, a computer interface, and an observation port/air inlet for continuous monitoring of the system's operating status. This product uses reliable integrated circuitry, providing a good working environment and strong anti-interference capabilities. The furnace shell temperature is ≤45℃ at its highest, significantly improving the working environment. It features microcomputer program control, programmable curves, fully automatic heating/cooling, and the ability to modify temperature control parameters and programs during operation, offering flexibility, convenience, and simple operation.

Temperature control accuracy: ±1℃ with no overshoot. Constant temperature accuracy: ±1℃. Rapid heating rate, with a maximum heating rate ≤30°C/min.

The furnace lining is entirely made of vacuum-formed high-purity alumina lightweight material, offering high operating temperature, low heat storage, resistance to rapid heating and cooling, no cracking or slag shedding, and excellent insulation performance (energy saving is over 60% of that of traditional electric furnaces). The rationally designed structure, with inner and outer double-layer furnace jackets and air-cooled heat dissipation, significantly shortens the testing cycle.

Application

It is a specialized piece of equipment designed for laboratories in universities and research institutes, as well as industrial and mining enterprises, for the sintering, melting, analysis, and production of ceramics, metallurgical, electronic, glass, chemical, mechanical, refractory materials, new material development, special materials, building materials, metals, non-metals, and other chemical materials.

Warranty	1-year free warranty for the whole furnace. Heating element: not covered by general warranty; free replacement for natural damage within 3 months.
Optional Accessories	1. Crucible, saggar, corundum / silicon carbide furnace plate 2. PC control software & hardware 3. Touch screen temperature controller 4. Consumables: heating elements
Notes	1. Recommended heating & cooling rate: 10-20℃/min. Excessively fast heating at high temperature will shorten service life of heating elements. 2. No vacuum sealing structure. Flammable and explosive gases are prohibited. 3. Tiny cracks on lining after long-term use are normal and do not affect operation. Can be repaired with alumina coating. 4. Corrosive gases are not recommended. Inform us in advance if strong corrosive gases (Sodium, Sulfur etc.) are required for special lining treatment. 5. Avoid high-temperature solution leakage onto furnace bottom; use bottom plate or alumina powder for isolation. 6. Place the furnace in dry and well-ventilated area.
