How To Deal with The "frequent Process Switching And Long Temperature Adjustment Time" in Multi-variety Sintering?

When dealing with the production mode of multiple varieties and small batches, traditional equipment often has low efficiency due to the cumbersome process switching. The requirements for sintering temperature curves, holding times, and atmosphere conditions of different materials vary significantly. If the equipment does not have flexible process adaptation capabilities, frequent process switching will lead to a large amount of waste of auxiliary time and energy consumption. The sintering furnace of Hunan Jingtan adopts a modular temperature control design, equipped with a programmable controller and a human-machine interface. It can store multiple process heating curves. Operators only need to call the process formula of the corresponding product, and the equipment can automatically execute the entire process of heating, holding and cooling, significantly reducing the time for production change adjustment. This "one machine, multiple processes" design enables enterprises to avoid configuring multiple dedicated devices for different products, significantly reducing equipment investment and factory space occupation.

The atmosphere switching function of the sintering furnace is another key to its adaptability to multi-variety production. The equipment can flexibly switch between vacuum and various protective atmospheres, meeting the full process requirements from degassing, degreasing to densification sintering. For materials that require treatment in a reducing atmosphere (such as anti-oxidation sintering of metal powders), hydrogen can be introduced during the sintering process. For materials that need to prevent the volatilization of alloy elements, the partial pressure sintering mode is adopted, and an appropriate amount of inert gas is filled in the high-temperature stage. The working atmosphere inside the furnace can be switched between vacuum and inert gas protection (slightly positive pressure). The equipment adopts resistive heating. The graphite tube heating element has a long service life, good heating effect, and is easy to maintain, ensuring the uniformity of the furnace temperature under vacuum conditions. This "multi-purpose in one furnace" design enables users to cover a wider range of process requirements with lower equipment investment.

The controllable cooling function of the sintering furnace during the cooling stage further enhances the process flexibility. The high-temperature section of the furnace body is cooled naturally, while the low-temperature section can be cooled at a faster rate by injecting positive pressure inert gas. Users can select different cooling rates based on the sensitivity of the materials - slow cooling is adopted for hard alloys that are prone to hot cracks, while rapid cooling is used for materials such as stainless steel to enhance efficiency. The explosion-proof valve for the furnace body designed by d Company is safe and reliable. The inner liner and flange of the furnace body are made of stainless steel, which does not rust and has a long service life. The modular design of the equipment also facilitates later expansion. Users can increase the furnace size or heating power configuration according to the demand for production capacity growth.
