A retort for thermally processing sinterable objects including a retort body having an interior cavity configured to receive at least one part for sintering. The retort body includes a retort inlet, a fore volume, an inlet plenum, an outlet plenum and a retort outlet. The retort inlet is configured to be fluidly connected to a process gas inlet tube and receive a flow of process gas. The retort inlet is fluidly connected to the fore volume, the fore volume being configured to receive a cleansing object. The fore volume is fluidly connected to the inlet plenum, which is fluidly connected to the interior cavity, which is in turn fluidly connected to the outlet plenum. The outlet plenum is fluidly connected to the retort outlet which is configured to be fluidly connected to an effluent gas outlet tube via a Peclet sealing element.

A sealing device for a vessel to achieve a fluid-tight seal in an aperture made in the lateral wall of said vessel, into which aperture a shaft is inserted. The sealing device comprises first sealing means disposed in contact with the shaft in the zone of said aperture, and second sealing means, comprising a containing body and a flexible connection element. The first sealing means comprise a plurality of sealing rings, disposed coaxial to the shaft and in contact with the latter, and a containing tube to contain the sealing rings. The lateral wall of the vessel comprises an interface flange. A closing flange is connected to the interface flange and to a flanged end of the containing body by means of attachment means and is positioned in contact with the containing tube and with the flexible connection element to keep the first sealing means in a determinate axial position with respect to the shaft.

An apparatus for the thermal heating of steel products that includes inside it a path for feeding the steel items which extends between an entry end and an exit end of the steel items, a mechanism for feeding a fuel, and a mechanism for feeding a comburent including oxygen, and burners able to operate the combustion of the fuel and of the comburent.

A sealing assembly for installation sealing between upper and lower hearths of a reflow oven, the sealing assembly comprising a sealing strip and a mounting seat, the mounting seat being disposed at the bottom of the sealing strip. The mounting seat is configured to be mounted on the reflow oven; the sealing strip is elastic and can be removably mounted on the mounting seat. A support part is disposed at one side and abreast of a sealing part, the support part being closer to a hearth position of the reflow oven than the sealing part is. The mounting seat enables quick fitting and quick removal of the sealing strip; the support part can greatly reduce the pressure acting on the sealing part, and effectively obstruct corrosion by flux and heat from inside the reflow oven, greatly extending the service life of the sealing strip.

A rotary tube kiln, with a rotatably mounted rotary tube, which has a motorized drive, a mounting, a material inlet and a material outlet, wherein the interior space of the rotary tube has a process space, the inside atmosphere of which is separate from the outside atmosphere. The process space is sealed off from a pressure space by means of a first seal and the pressure space is sealed off from the outside atmosphere by means of a second seal and, by means of a pressing device, a first pressing force can be applied to the first seal and a second pressing force can be applied to the second seal, the first pressing force can be set independently of the second pressing force and, during operation, the internal pressure of the pressure space is higher than the internal pressure of the process space.

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.

A furnace system has a furnace-tube-cap (FTC) and a slider. The FTC has a first-cap-portion coupled to a furnace tube of a furnace, a second-cap-portion with a bearing-assembly-arrangement (BAA), and an inner-tube-cap-channel (ITCC) passing from the first-to-second cap portion with an ITCC sealing arrangement extending outside the ITCC. The slider slides in the BAA to/from inject-and-rinse positions, and has a first-ramp (FR), a first-raised-surface (FRS), an intermediate-lower-surface (ILS), a second-ramp (SR), and a second-raised-surface (SRS). When the slider moves to the inject-or-rinse positions, the BAA forces a slider-part to push against an inner-channel-sealing-arrangement (ICSA) as the BAA goes from the FR-to-FRS, or the SR-to-SRS. When the slider is in the inject-or-rinse position, a first-slider-part seals the ITCC sealing arrangement. When the slider transitions between the inject-and-rinse positions and the BAA rides along the ILS, the BAA allows the slider-part to float above the ICSA arrangement.

A rotary tube kiln, with a rotatably mounted rotary tube, which has a motorized drive, a mounting, a material inlet and a material outlet, wherein the interior space of the rotary tube has a process space, the inside atmosphere of which is separate from the outside atmosphere. The process space is sealed off from a pressure space by means of a first seal and the pressure space is sealed off from the outside atmosphere by means of a second seal and, by means of a pressing device, a first pressing force can be applied to the first seal and a second pressing force can be applied to the second seal, the first pressing force can be set independently of the second pressing force and, during operation, the internal pressure of the pressure space is higher than the internal pressure of the process space.

A sliding style furnace cap features a furnace tube cap and a slider. The furnace tube cap has a first cap portion to couple to a furnace tube of a furnace, and a second cap portion with a bearing assembly arrangement. The furnace tube cap also has an inner tube cap channel passing through it with an inner tube cap channel sealing arrangement configured to extend outside the inner tube cap channel. The slider has an orifice/channel configured therein passing through the slider, couples and slides in the bearing assembly arrangement from an inject position to a rinse position, and vice versa, has a cam-like contoured surface with a first ramp configured to couple a first raised surface and an intermediate lower surface, and with a second ramp configured to couple the intermediate lower surface to a second raised surface. The slider also moves towards the inner tube cap channel and causes the bearing assembly arrangement to force a part/side of the slider to push against the inner channel sealing arrangement as part of the roller bearing arrangement rides up either the first ramp to the first raised portion when the slider is moved to the inject position, or the second ramp to the second raised portion when the slider is moved to the rinse position, and the first part of slider configured to seal the inner tube cap channel sealing arrangement when the slider is in either the inject position or the rinse position. The slider also moves away from the inner tube cap channel and causes the bearing assembly arrangement to allow the part/side of the slider to float above the inner channel sealing arrangement as the part of the roller bearing assembly rides along the intermediate lower surface when the slider is in transition between the inject position and the rinse position.
