高温热压炉结构特点：

燃烧室和热区

试验箱从前面加载，并包含直径为4“x 8”高（102 mm x 203 mm）或8“直径x 10”高（203 mm x 254 mm）的热区，温度梯度为+/-10°C。加热元件是1/2-1/2分体式设计，允许模具主体直接插入区域。炉室由双壁不锈钢制成，焊接在一起，经过电抛光，表面光洁度和真空度良好。

热区有三种选择：石墨带元件和刚性纤维石墨绝缘包，钼-D棒元件和陶瓷绝缘包，或高温金属网加热元件和层状金属屏蔽。在热压配置中，工作温度可达2300°C（陶瓷区为1650°C）。通过提供端塞护罩来堵塞顶部和底部热棒开口，熔炉可以用作一个操作温度为2600°C的间歇/烧结炉。

液压机

高温热压炉带负载链的柱压板压力机的设计和制造可承受超过15吨的力。与市场上的一些标准焊接“H”型框架不同，这种立柱和台板框架可调，以实现良好对齐。负载系统包括水冷不锈钢顶部和底部冷棒，以及高强度顶部和底部热棒。顶杆具有4、0〃冲程，顶部冷杆由波纹管组件上的静态O形环密封，以提供高真空额定密封。

液压机控制系统包括4、0〃行程液压缸、液压动力单元、压力表和测压元件，用于测量和控制压力。计算泵尺寸和伺服阀尺寸，以允许快速点动加载和定位。提供了用于精细定位的慢速点动速度。气缸位置精度为0.001〃，压力精度为1 lb（5 N）。

电源和控制

热区的电源由三相可控硅控制电源供电，符合*新的NFPA和NEC规范（可获得CE认证）。电源的设计与加热元件相匹配，并且其尺寸允许快速上升。变压器包括多个抽头，可在元件和屏蔽老化但仍可用时使用。一组水冷电力电缆为熔炉的热区供电。

温度和力控制可通过经典仪器和按钮，或通过SCADA/HMI系统实现。压力和温度控制程序可以同步。HMI系统记录数据，提供用户安全性，显示图形、警报，并为全炉控制提供直观的图形用户界面。

提供“C”型铠装和涂层热电偶，可用于测量高达2000°C的炉温。当炉子运行到高于2000°C的温度时，控制自动切换到高温计。

真空和气体系统

基本抽真空系统由旋转叶片机械泵、电空真空阀、真空计控制器和真空计组成。该真空系统允许在真空环境（10-2托范围）下运行，也可提供可选的4〃或6〃扩散泵送系统或涡轮泵送系统，并可达到10-6 Torr（扩散泵送系统）和10-7 Torr范围（涡轮泵送系统）的真空水平。

在热试验和物理试验期间，所提供的基本气体系统为工作样品提供了一个惰性环境。工艺气体系统包括一个电磁阀操作的入口阀、一个复合仪表（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，以保持正的腔室压力。可选的分压系统，氢气操作，气体比率的质量流量控制器，和其他选项也可用。

水冷系统

炉水冷却歧管由多个回路组成，以充分冷却熔炉的所有部件，包括过滤器、压力调节器、压力计、进水和出水歧管、水流开关（作为可视水流指示器，带有流量联锁装置），以在水流发生故障时保护熔炉。如果水流量低于建议的*小值，此开关将关闭热区的电源

Chamber and hot zone

The chamber is loaded from the front and contains hot zone sized 4” diameter x 8” high (102 mm x 203 mm) or 8” diameter by 10” high (203 mm x 254 mm) with a +/- 10°C temperature gradient. The heating element is a 1/2- 1/2 split design allowing the die body to be inserted straight into the zone. The furnace chamber is manufactured from doubled-walled stainless steel welded together and electro-polished for a clean finish and good vacuum integrity.

Three hot zone choices are available: a graphite bａnd element and rigid fibrous graphite insulation pack, a Moly-D rod element and ceramic insulation pack, or a high temperature metal mesh heating element and layered metal shielding. In the hot press configuration, the maximum operating temperature is 2300°C (1650°C with ceramic zone). With the end plug shields supplied to plug the top and bottom hot rod openings, the furnace can be used as a batch/sintering furnace with operation temperatures to 2600°C.

Hydraulic Press

The Post and Platen Press Frame with load train is designed and manufactured to withstａnd well over 15 tons of force. This Post & Platen Frame is fully adjustable for perfect alignment, unlike some standard welded “H” frames on the market. The load train includes water-cooled stainless steel top and bottom cold rods, and high strength top and bottom hot rods. The top rod has a 4、0″ stroke and the top cold rod is sealed by a static O-Ring on a bellows assembly to provide a high-vacuum rated seal.

The Hydraulic Press Control System includes a 4、0″ stroke hydraulic cylinder, a hydraulic power unit, a pressure gauge, and a load cell to measure and control press force. The pump size and servo valve size are calculated to allow fast jogging speeds for loading and positioning. A slow jog speed for fine-positioning is also provided on our HMI systems. Cylinder positional accuracy will be 0.001″ and press force accuracy of 1 lb (5 N).

Power Supply & controls

Power to the hot zone is supplied by a three phase SCR-controlled power supply, meeting the latest NFPA and NEC codes (CE certification available). The power supply is designed to match the heating element, and is sized to allow for fast ramp rates. The transformer includes multiple taps which can be used when the element and shields are aging but still usable. A set of water-cooled power cables supplies power to the hot zone of the furnace.

Temperature and force control is accomplished either with classic instruments and push buttons, or by means of a SCADA/HMI  system. Press force and temperature control programs can be synchronized. The HMI system logs data, provides user security, displays graphs, alarms, and provides an intuitive graphical user interface for full furnace control.

A type “C” sheathed and coated thermocouple is supplied and can be used to measure the furnace temperature up to 2000°C. When operating the furnace to temperatures above 2000°C, control is automatically switched over to a Pyrometer.

Vacuum and Gas System

The basic evacuation system consists of a Rotary Vane mechanical pump, an electro-pneumatic vacuum valve, vacuum gauge controller and a vacuum gauge. This vacuum system will allow for operation in a vacuum environment (10-2 Torr range) An optional 4″ or 6″ diffusion pumping system or a turbo pumping system can be provided as well and can achieve vacuum levels down to 10-6 Torr (diffusion pumping system) and 10-7  Torr range (turbo pumping system).

The basic gas system supplied provides an inert environment for the work samples during the heat and physical testing. The process 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 positive chamber pressure. Optional partial pressure systems, hydrogen operation, mass flow controllers for gas ratios, and other options are also available.

Water cooling system

The furnace water cooling manifold consists of multiple circuits to adequately cool all the furnace parts and includes a strainer, pressure regulator, pressure gauge, water inlet and outlet manifold, a water flow switch as a visual water flow indicator with a flow interlock to protect the furnace in the event of a water flow failure. This switch turns off power to the hot zone if water flow is below recommended minimum for a certain amount of time. Each part of the furnace is supplied with a separate cooling circuit that can be regulated by independent manual ball valves.

Utilities

Power: kVA dependent on max temperature rating, 380-480 V/3/50-60 Hz (other voltages available)

Water: 70 F (20°C) and 50 P.S.I.G. (3、4 bar), required flow dependent on kVA rating.
