Quenching trolley furnace is a periodic operation furnace, the furnace part is a box type structure: the furnace bottom is a movable trolley. Before heating, the trolley is loaded outside the furnace, the heating parts are placed on the high-temperature furnace bottom plate, then the trolley is pulled into the furnace by the traction device for heating. After heating, the trolley is pulled out of the furnace by the traction device for unloading, then the heated workpiece is hoisted to the forging equipment for secondary processing by crane. The trolley quenching furnace is mainly used for steel castings, automobile parts, rolls, steel balls, metal structural parts, welding parts, high chromium, high manganese steel castings, ductile iron, rolls, steel balls, 45 steel, stainless steel quenching other heat treatment purposes.
The trolley type quenching furnace is divided into high-temperature furnace, medium temperature furnace low-temperature quenching furnace. The rated service temperature of high-temperature furnace is within 1200 ℃, that of medium temperature furnace is within 950 ℃, that of low-temperature quenching furnace is within 650 ℃. The extruded products can be heated uniformly rapidly; the materials can be put into the quenching pool in a very short time; the bending torsion deformation of extruded products caused by self weight heating can be avoided, the shape of products can be maintained; the mechanical properties of the extruded products after quenching are uniform.
Features of all fiber trolley type quenching furnace are as follows:
1: Compared with the traditional furnace, the new ceramic fiber structure can save energy by 15-30% the service life can be up to 5-8 years.
2: Trolley walking furnace door lifting are all electric, stable operation simple operation.
3: The heating element is wound into wave shape with high resistance electrothermal alloy tape. The surface load can reach 1.6 ~ 2.0w/cm2, the service life is up to 3-5 years. The material of resistance band is 0cr21a16nb.
4: Sand seal is used for trolley seal spring compression device is used for furnace door seal, which has high sealing performance, greatly saves energy consumption reduces the use cost.
5: The control system is composed of a microcomputer intelligent controller a silicon controlled rectifier module. The control accuracy can reach ± 1 ℃ to ensure the process temperature curve of the product.
6: The self-locking device is used for trolley access furnace door lifting to prevent workers misoperation equipment damage.
7: The load-bearing part of the trolley is built with high strength high aluminum heavy bricks.
8: Integrated rail connection, no foundation is needed, ground plane can be fixed, installation is simple.
The trolley furnace is mainly used in glass, aerospace, mechanical electronics, bioceramics, powder metallurgy other fields. It is used for glaze sintering of ceramic products, baking of silicon carbide coating heat treatment of mechanical parts.
