Traditional methods for mold baking mould for foundry, an extended box-type electric furnace, diesel-powered Grill. This method of baking is the sand mold is placed in the baking mould heating furnace, hot place gradually from within the sand penetrated the outer wall layer is dry. Because of this method of heating the sand cast appearance parts that must not be heated at the same time, such as heating, both heating time, and wasted energy. While this heating mode does not enable the cavity, various sections within the sand cement sand and sand filling, sealing PuTTY, Shi Miansheng fully dry, as well as sand and mud core bad vent. -Sand and mud core cracks, thus affecting the casting quality of castings. In particular this heating method for large cast in boxes, cores in mold oven kiln baked, cool in distribution boxes in the process result in the return of damp, cannot cast meets the necessary requirements. In order to address these challenges, my factory technical force, the advantages of collecting a variety of baking furnaces, research, development of modern casting technology requires ZTK series casting drying furnace, casting bake mode, the maintenance of mould dehumidification and thermal moisture removing device of choice, among which ZTK-80-3 casting drying furnace in November 2005 by the Zhejiang Provincial Science and Technology Commission to identify new products.
Save for cast appearances and sand boxes, which do not need to be heated when partially dry heat, but also save the sand, core drying time.
Hot-blast stove in a certain amount of pressure from within the cavity to the outside heat, which can speed up the drying process, but also within the cavity in the sand is a part of core and some sand, sealing PuTTY, asbestos rope fully dry, keep the heat, the sand core vent-free, to cast exhaust.
Because of the mechanical equivalent of wind is a continuous flow of hot gas flow, thus the cavity heating surface is very uniform, small temperature difference, the sand mold and core will not warp and crack, so casting quality is assured.
Automatic control of hot stove during normal operation may implement, from low temperature to high temperature during the entire heating process step by step, and casting requirements can be controlled within the cavity temperature, ensure the quality of casting.
Hot-blast stove used method is a simple, casual lifting moves in the ring when baking tu no pollution, no residues inside the mold cavity, reduce labor intensity.
Note: according to user needs to provide a variety of products.
