Shanghai Qunjie Machinery Equipment Co., Ltd. adheres to the entrepreneurial spirit of "proactive and creative excellence", is based on the machinery manufacturing industry, is dedicated to hot air fans (industrial hot air sources), fast drying equipment, heating equipment, hot air drying tunnels / ovens / drying Housing, hot air tunnel furnace, heating project, temperature environment simulation system, fast-drying production line, high temperature sterilization and other related products, systems, engineering design, research, production, installation and commissioning, maintenance and other services, is an independent research and development Capabilities of modern scientific and technological manufacturing enterprises.

Shanghai Qunjie, as Shanghai's first hot air blower production base, produces a cast industrial hot air blower ; a comprehensive all- rounder for you to specifically address the problems encountered in the production process of castings, and summarizes a few points for your reference:

First, after the mold cavity is demolded, it needs to be cleaned up, coated with coating, and then transferred into the drying room. After a long period of high temperature baking, it comes back and forth, resulting in a lot of waste of manpower and material resources. Finally, the cavity is not completely dried. The waiting time after closing the box is too long, which causes the surface of the cavity to regain moisture. During the pouring process, a large amount of gas is generated, which affects the flow rate of molten steel (molten iron) in the cavity to slow down, which causes the product to contain sand and pores. Defective or scrapped.

Second, the traditional cavity baking mode, it seems that after a long period of high temperature baking, the fuel and the torch are used, why the cast product may still have defects or scraps, which is actually incomplete, so-called If the speed is not reached, it may also affect the way of the sand box, and the sand mold may cause looseness or strength reduction due to the local surface temperature being too high. When pouring molten steel (hot metal), the phenomenon of sand inclusion will occur.

Third, the industrial mold hot air blower fills this gap. You just need to clean up the sand mold and close it to meet the pouring requirements. Then start the industrial mold hot air blower and set the required temperature, provided that the air outlet of the hot air blower must be It can only match with the gate or riser of the cavity, and send the wind speed, temperature, pressure; hot air with sufficient air volume to the inside of the cavity, and at the same time cover the excess riser and gate accordingly, without special strictness, so that the inside of the cavity Forming positive pressure, hot air will penetrate the surface and interior of the cavity, forcing away moisture for 2-3 hours. Production can be arranged according to the production cycle, and the operation is simple. It can be removed before pouring. Repeatedly. Improved the quality of castings and greatly improved production efficiency.

4. The role of the mold industrial hot air blower in the foundry industry. The specifications and sizes of the products produced by various enterprises are different, and the models they choose are different. The above points briefly describe the conclusions of the company after serving the relevant enterprises. You reference.
