结构特点:

Chamber and Hot Zone

燃烧室和热区

The chamber is loaded from the front and contains a Hot Zone with a 24″ x 24″ x 24″ usable zone and a +/- 10℃ temperature gradient. The rod heating elements provide four-sided heating. The elements feature excellent uniformity and longevity. The furnace chamber is manufactured from double-walled stainless steel welded together and polished for a clean finish and good vacuum integrity.

燃烧室从前面加载,并包含一个热区,其可用区为24〃x 24〃x 24〃,温度梯度为+/-10℃。棒加热元件提供四边加热。这些元素具有极好的均匀性和寿命。炉室由焊接在一起并抛光的双层不锈钢制成,以获得干净的表面光洁度和良好的真空完整性。

Chamber ports allow auxiliary equipment and sensors to access the chamber environment. The hot zone shields are mounted in a chamber frame, allowing for the thermal growth of the zone during the heat cycling. The chamber has both a front and rear door for complete and easy access to the hot zone, facilitating loading, unloading and maintenance.

腔室端口允许辅助设备和传感器访问腔室环境。热区护罩安装在一个腔室框架内,允许热循环期间区域的热增长。燃烧室有一个前门和后门,便于进入高温区,便于装卸和维护。

The gas heat exchanger and circulator allows for quick-cooling down to room temperature.

气体热交换器和循环器允许快速冷却到室温。

A load frame supports the furnace load and is engineered to allow a high load capacity while minimizing thermal conductivity losses to the chamber walls. An optional load cart facilitates loading and unloading of large and heavy loads.

一个负载框架支持熔炉负载,并设计成允许高负载能力,同时尽量减少对炉壁的热导率损失。可选的装载车便于装载和卸载大型和重型货物。

Power Supply & Controls

电源和控制

The power supply is sized and designed to match the elements and power usage at the maximum furnace temperature. Extra secondary transformer taps are provided to accommodate changing characteristics of aging elements and shielding and to extend the useful life of the hot zone.  Water-cooled power cables supply power to the hot zone of the furnace, allowing the cables to be smaller in size. All protective and safety devices are incorporated, meeting all applicable NFPA standards.

电源的大小和设计应与*高炉温下的元件和功率使用相匹配。提供额外的二次变压器分接头,以适应老化元件和屏蔽的变化特性,并延长热区的使用寿命。水冷电力电缆为熔炉的热区供电,使电缆尺寸更小。所有的保护和安全装置都是一体的,符合所有适用的NFPA标准。

Furnace control is established through either the classic control panel with switches, lights, temperature controller and vacuum instrument, or by means of a Computer Interface package with HMI software and Industrial touch-panel PC. Both offer full control of the furnace and are easy to operate. The Computer package adds data acquisition, alarms, recipe storage, security and networking.

熔炉控制通过带开关、灯、温度控制器和真空仪表的经典控制面板,或通过HMI软件和工业触摸屏PC的计算机接口包来建立。这两种控制都提供了对熔炉的完全控制,并且操作简单。计算机包增加了数据采集、报警、配方存储、安全和联网。

A type “C” sheathed thermocouple is used to measure the furnace temperature. A safety over-temperature controller shuts off power to the hot zone if the maximum operating temperature is exceeded.

“C”型铠装热电偶用于测量炉温。如果超过*高工作温度,安全超温控制器会切断高温区的电源。

Vacuum System

真空系统

The basic system, an evacuation system, consists of a Rotary Vane mechanical pump, an electro-pneumatic

vacuum valve, and a vacuum gauge. This vacuum system will allow for operation in a vacuum environment (10-2 to 10-3 Torr range).

真空阀和真空计。该系统在真空环境下工作(真空范围为10-10)。

A 16″ or 20″ diffusion pumping system can be provided to achieve vacuum levels down to 10-6 Torr. All our diffusion pumping systems include a refrigerated cold trap to prevent oil backstreaming and to obtain a lower ultimate vacuum.

可提供16〃或20〃扩散泵系统,以达到10-6托的真空水平。我们所有的扩散泵系统都包括一个冷藏的冷阱,以防止石油回流并获得较低的极限真空度。

A turbo pumping system is available upon request to obtain a vacuum level of 10-7 to 10-8 Torr range.

可根据要求提供涡轮泵系统,以获得10-7至10-8托范围的真空度。

Gas System

气体系统

An inert or hydrogen gas system provides an inert or reducing environment for the work samples during the heat testing.

惰性或氢气系统在热试验期间为工作样品提供惰性或还原性环境。

The basic inert gas system includes a solenoid-operated inlet valve, a compound gauge (30 P.S.I.G. x 30 in. Hg.), a gas flow meter, and a 2 P.S.I.G. outlet relief valve to maintain a positive pressure.

基本惰性气体系统包括一个电磁阀操作的进气阀,一个复合压力表(30 P.S.I.G.x 30 in。一个气体流量计和一个2P.S.I.G.出口安全阀,以保持正压力。

Mass flow controllers for programmable gas flows, partial pressure control, and operation in wet or dry hydrogen is all available. We customize the gas system to meet process requirements.

可编程气体流量、分压控制和湿氢或干氢操作的质量流量控制器均可用。我们定制气体系统以满足工艺要求。

Water Cooling System

水冷系统

The furnace water cooling system consists of an inlet and outlet manifold to distribute water effectively throughout the furnace components. Each water circuit can be regulated by independent manual ball valves to maximize cooling efficiency. A water flow interlock protects the furnace in the event of a water flow failure. Power to the hot zone is turned off if water flow is below recommended minimum for a certain amount of time.

炉水冷却系统包括一个入口和出口歧管,用于在整个炉子部件中有效地分配水。每个水回路可由独立的手动球阀调节,以*大限度地提高冷却效率。水流联锁装置在水流故障时保护熔炉。如果水流在一定时间内低于建议的*小值,则关闭热区的电源。
