Tungsten carbide is hard and long-lasting. It is utilis to construct tools, dies, and wear-resistant piece. For producing these long-lasting parts, Carbide Sintering is one of the key processes. The process hardens the material and makes it ready for use.
In short, sintering is a process of heating a powder substance to extremely high temperatures. It does the job of keeping the powder intact as a solid. When it comes to tungsten carbide, it's one process that's a necessity. It determines the shape of the end product and even hardens it. The chief instrument which is employed to accomplish the same for tungsten carbide is that of its sintering furnace.
What is Carbide Sintering
Sintering of carbide is heating of metal powder so that particles bond with each other. Furnace heats material to about 1,400°C to 1,600°C. That is when metal powder begins to melt . The material does not melt. It gets only heated enough so that the particles adhere to one another.
This process forms voids between the powder particles. It hardens and densifies the material. It helps improve the product's strength, form, and finish.
Role of the Tungsten Carbide Sintering Furnace
Two major steps are involved in carbide sintering. The first occurs when pressed tungsten carbide powder is loaded into the furnace. Then the stove is heated gradually.
As the temperature increases, a binder substance in the powder melts and flows into the structure. This causes the grains to stick together more. Then, the binder is dissolved in the subsequent step. The piece is then cooled under controlled conditions.
The Tungsten Carbide Sintering Furnace helps maintain consistency in the process. It employs sensors and timers to control the heat and pressure. This keeps cracks and weaknesses from occurring.
Types of Sintering Methods
There are two major types of carbide sintering:
● Vacuum Sintering: This method evacuates air from the furnace. It avoids undesirable chemical reactions and keeps the material clean and robust.
● HIP Sintering (Hot Isostatic Pressing): This process consists of adding the pressure of gases along with heating. It packs grains more closely together. It also gives a more even and crack-free surface.
A case study at a factory producing tools revealed remarkable results. Vacuum sintering enhanced the strength of the tools by 15%. It also made the parts last for 20% longer in harsh-duty applications.
Why Temperature Control is Important
Good heat control is important. Any small temperature change will affect the final strength of the part. A 10°C increase or decrease alone will make an impact.
Intelligent temperature sensors are used in modern furnaces today. These sensors help keep the amount of heat stable. That means fewer flaws and better quality with every batch.
Energy Consumption in Sintering
Sintering uses a lot of energy. Having low energy use saves money and reduces wastage. Some types of tungsten sintering furnaces use power-saving technology. These can decrease the use of electricity by 12%. That is good both for cost savings and performance.
Advantages of Carbide Sintering
This sintering is a consistent process. It yields hard, wear-resistant components with good shape and surface finish. If done properly, it reduces material wastage and product life span. Different industries like mining, metal cutting, and drilling often employ the process. The reason is that it generates good results with no excessive failure rates.
