摘要： A metal melting installation in which a movable carrier has a kiln door fixed at its front end for closing an entrance opening of the kiln and a crucible provided forwardly of the door so as to lodge in the kiln when the entrance opening is closed. A drive means for closing the carrier comprises: an electric motor in a control circuit that also includes a limit switch mounted adjacent the kiln entrance opening; a chain and sprocket gear for moving the carrier; a damper device interconnecting the drive shaft of the motor and one sprocket wheel of the gear for allowing it to keep on rotating to dissipate accumulated momentum energy when the motor is de-energized, a push button being provided on the carrier for contacting the limit switch to thus cut off the electric circuit and deenergize the motor when the door on the carrier closes the kiln opening.

摘要： A high temperature car bottom furnace is provided with an improved seal on the mating closing surfaces. The side walls of the furnace chamber have tapered bottom surfaces sloping toward the end wall of the furnace chamber. The moving furnace floor is provided with complementary tapered sealing surfaces mating with the bottom surfaces of the side wall. A resilient compressible insulating layer is secured therebetween for sealing the chamber along each side wall. This arrangement not only reduces the abrasive contact between the moving surface and the compressible insulating layer but also facilitates non-abrasive closing action by the door wall of the furnace.
摘要翻译：高温车底炉在配合的关闭表面上提供改进的密封。炉室的侧壁具有向炉室的端壁倾斜的锥形底面。移动的炉底设置有与侧壁的底面配合的互补的锥形密封表面。弹性可压缩绝缘层被固定在它们之间以沿着每个侧壁密封腔室。这种布置不仅减少了移动表面和可压缩绝缘层之间的磨料接触，而且还有助于炉的门壁的非研磨闭合作用。

摘要： Disclosed is a sintering furnace comprising a furnace body and a lifting device, wherein the furnace body comprises a furnace chamber (10) and a furnace mouth (20), the furnace chamber (10) is connected with the furnace mouth (20), wherein the sintering furnace further comprises a sealing member (30) provided at the lifting device; when the sintering furnace is in a loading or unloading condition, the sealing member (30) blocks the furnace mouth (20). When the sintering furnace is in an unloading condition, the sealing member (30) can block the furnace mouth (20), the furnace chamber (10) does not contact with the outside directly, thus the temperature in the furnace chamber (10) will not drop sharply, and the service life of the sintering furnace will be increased.

摘要： An industrial furnace (1) into which protective gas is admitted for the heat treatment of batches (5) of metal workpieces is described. The heat treating furnace includes an entrance lock (2) which can be sealed with respect to the surrounding environment by means of a first gas-tight closure device (2.2.1). The heat treating furnace also includes a third gas-tight closure device (3.1) disposed between a heat treatment chamber (3) of the furnace and a quenching facility (4) at the exit of the heat treatment chamber. With the foregoing arrangement a pressure of the protective gas admitted into the heat treatment chamber (3) can be maintained during loading and unloading of a batch of metal workpieces (5). The entrance lock may be configured as a dual-chamber vertical arrangement or as a single chamber horizontal arrangement.

摘要： An oven for the partial heat treatment of tools, for example, twist drills,omprises a first section, which contains the heating chamber that is constantly at the desired operating temperature. A second section for the loading and unloading and the quenching is provided. Between the two sections there is arranged a transport device for the charges of tools. The oven may be in the form of a one-chamber or three-chamber vacuum oven. The oven provides a high heat transfer rate, because the heating chamber is constantly at the desired operating temperature and the heat transfer by heat radiation under vacuum is started immediately when the charge is at its final position inside the heating chamber.
