What waste gas does the mesh belt sintering furnace produce during high-temperature sintering? How to deal with it?

Generally speaking, when the mesh belt furnace is sintered, hydrogen is passed. The possible exhaust gas is carbon monoxide, etc. You can open vents in the high-temperature furnace. If you directly use an open flame to ignite the exhaust carbon monoxide, it will be dangerous, because it cannot be completely carbon monoxide. , There will be hydrogen (because it is necessary to eliminate the risk of explosion caused by hydrogen), it is best to connect a pipe to the exhaust hole and exhaust the exhaust gas outside.

Hydrogen is mainly used to reduce oxides in iron-based products. Nitrogen is mainly used for protection. Because the concentration of hydrogen is too high, it will explode. Therefore, the ratio of hydrogen to nitrogen must be controlled.

This difference should be called a stove because of the smaller ones, because the large-scale gasifiers basically do not use electricity and water. Most of our company's gasifiers are 30-300KG gasifiers. Generally, we can also make them. It's called a gasifier, I don't know if it's right

(1) The processing temperature is low, the time is short, and the deformation of the workpiece is small.

(2) Not limited by steel type, carbon steel, low alloy steel, tool and die steel, stainless steel, cast iron and iron-based powder non-metallurgical materials can all be soft-nitrided. The surface hardness of the workpiece after nitrocarburizing is related to the nitriding process and material.

(3) It can significantly improve the fatigue strength, wear resistance and corrosion resistance of the workpiece. It also has anti-abrasion and anti-seize properties under dry friction conditions.

(4) Since there is no brittle ξ phase in the soft nitrided layer, the nitrided layer has certain toughness and is not easy to peel off.

Therefore, nitrocarburizing has been widely used in the treatment of wear-resistant workpieces such as molds, measuring tools, cutting tools (such as high-speed steel cutting tools), crankshafts, gears, cylinder liners, and mechanical structural parts.
