Category:
【Summary Description】Products like vacuum double-action pressure sintering furnaces are essentially industrial tools—most of us have never seen or even heard of them. You could say they’re not commonly encountered in everyday life, yet they play an indispensable role in the industrial sector. So, the first thing we need to understand clearly when using these machines is their structure. Let’s dive in and explore it together!
Like Vacuum Dual-Direction Pressurized Sintering Furnace These products are primarily used in the industrial sector—most of them are unfamiliar to us, and we’ve likely never even heard of them. You could say they’re not commonly encountered in everyday life. Yet, in the industrial world, they play an indispensable role. So, the first thing we need to understand clearly when using them is the structure of a vacuum double-action pressurized sintering furnace. Let’s dive in together and explore it further!
Vacuum Dual-Direction Pressurized Sintering Furnace It refers to a furnace used for protective sintering of heated objects in a vacuum environment. There are various heating methods, such as resistance heating, induction heating, microwave heating, and more. The vacuum sintering furnace specifically employs induction heating to achieve protective sintering of the material being processed. Meanwhile, the vacuum dual-pressure sintering furnace is a complete set of equipment designed for industrial production; it utilizes the principle of medium-frequency induction heating under vacuum or protective gas atmospheres to sinter cemented carbide cutting tools and compacted metal powder briquettes.
The vacuum double-action pressurized sintering furnace features a vertical design with a dual-layer water jacket. Both the inner and outer walls, as well as the flanges, are made of 304 stainless steel. The furnace body is divided into two sections: one-third consists of the furnace lid, which can be manually opened fully to the side, while the remaining two-thirds comprise the fixed furnace housing—a uniquely designed component that ensures convenient operation. The vacuum system includes an oil diffusion pump, a Roots pump, and a mechanical pump equipped with an electromagnetic differential pressure valve (to prevent oil backflow in case of sudden power failure). It also features inflation valves, exhaust valves, a vacuum butterfly valve, and a vacuum pressure gauge (with ±Pa accuracy), all connected via a network of vacuum pipelines and supporting brackets. The hydraulic system of the vacuum double-action pressurized sintering furnace primarily utilizes electrically powered input. The hydraulic station is outfitted with imported proportional valves, pressure sensors, displacement indicators, and grating scales (offering measurement accuracy down to 0.02 mm), along with hydraulic cylinders and other essential components. Pressure adjustment is semi-automatic, allowing manual overrides when needed. Additionally, the system can be programmed for automatic pressure regulation, enabling stable pressure maintenance and extended holding pressure during the process.
Vacuum Dual-Direction Pressurized Sintering Furnace The water-cooling system consists of various valves and piping components, equipped with a water-loss audible and visual alarm that automatically shuts off the heat source or system function. The temperature-control system utilizes thyristor-based temperature regulation, featuring PID-controlled instruments and digital display meters—with an over-temperature audible and visual alarm capability. Alternatively, it can be configured for PLC-based touchscreen automatic control, while also retaining historical data for easy analysis of the sintering process. The inflation system is composed of diverse pipes and valves, complete with an electromagnetic vent valve and pressure sensors. If the furnace pressure exceeds the safety threshold, the system automatically releases excess gas. Additionally, the inflation lines are fitted with needle valves to precisely regulate the amount of gas introduced.
The above article provides you with the basic information about vacuum double-action pressurized sintering furnaces—have you already gotten a grasp of it? If not, be sure to read through it right away! Alright, that’s all for now on the key points about vacuum double-action pressurized sintering furnaces. I hope this has been helpful to you.
