Problems solved by technology
As a key component of the holding furnace, the furnace door of the holding furnace needs to be opened and closed frequently, and it is the most likely to be damaged or leaked. Therefore, the furnace door should also have the disadvantages of being convenient and flexible to open and close, and having the effect of heat preservation and sealing
The existing low-pressure casting holding furnace mainly adopts the traditional furnace door structure with a handle, which can only withstand a pressure of no more than 0.1 MPa, while the furnace pressure of a high-pressure pressure casting machine can reach 0.6 MPa. At the same time, the furnace wall of the holding furnace needs to bear the huge pressure in the furnace. Therefore, in the casting process, in order to ensure safety, the furnace wall must have sufficient strength, resulting in thicker insulation or refractory materials for the furnace wall, increasing cost

The invention discloses a casting holding furnace with a round a quick double-furnace-door structure. The casting holding furnace with the round quick double-furnace-door structure is characterized in that the double-furnace-door structure comprises a first clamp and a second clamp which are installed on the two sides of the double-furnace-door structure, the first clamp and the second clamp are installed on a furnace opening, locking is achieved through quick locking mechanisms, the first clamp and the second clamp slide leftwards and rightwards through a sliding mechanism and are both semicircular, and when the first clamp and the second clamp are locked, a circular frame is formed and the frame fastens furnace doors, and a furnace door rotary arm is installed on the furnace doors and connected with a swing arm shaft in a hinged or pivoted mode. According to the casting holding furnace with the round quick double-furnace-door structure, quick locking / opening and good airtightness of the furnace doors are achieved, locking strength is high, the pressure-bearing level is high, the structure is simple and flexible, and the service life is long.
Description
technical field [0001] The invention belongs to the technical field of casting equipment, and in particular relates to a casting holding furnace with a circular quick-opening door. Background technique [0002] In the field of casting, when it comes to smelting, heat preservation, transfer or pouring of metal melt, it is necessary to use the holding furnace of the metal melt. Taking aluminum alloy low pressure casting as an example, the holding furnace is an important part of the low pressure casting system. For aluminum In terms of alloy heat preservation, the basic requirements include heat preservation performance and sealing performance, and the sealing performance and heat preservation performance are directly related to the controllability of casting process parameters and the stability of molten aluminum temperature. At the same time, the pressure that the holding furnace needs to bear includes the gas pressure in the process of raising the liquid and maintaining the ...
