针对传统的气氛保护加热炉炉门出现的问题,提出了一种改进结构的炉门及其升降装置。实践表明,上述结构的应用提高了炉门的密封效果,降低了设备的生产和维护成本,保证生产工艺的连续性,提高炉子的使用安全性和可靠性。 Aiming at the problems that occur in the furnace door of traditional atmosphere protection furnace, an improved structure door and its lifting device are proposed. The practice shows that the application of the above structure improves the sealing effect of the furnace door, reduces the production and maintenance costs of the equipment, ensures the continuity of the production process and improves the safety and reliability of the use of the stove.
