摘要： The subject of the present invention is a shielding shoe for covering openings in the bottom of a walking beam furnace, the shielding shoe having a semi-circular recess and can thereby be taken up by a vertical support of the walking beam furnace. The shielding shoe consists essentially of refractory cast concrete or refractory rammed concrete and, according to the invention, has a honeycomb-like structure below the shielding jacket. The present invention also relates to a walking beam furnace with such shielding shoes.

摘要： A furnace door sealing device for a low-pressure diffusion furnace is provided. The furnace door sealing device includes a furnace door, a fixed shaft and a fixed base which are coaxially arranged in sequence from front to back. A bearing pedestal is fixed at the center of the rear end surface of the furnace door. A centripetal knuckle bearing is arranged in the bearing pedestal. An outer ring of the centripetal knuckle bearing is fixed in the bearing pedestal. An inner ring of the centripetal knuckle bearing fixedly sleeves the front end of the fixed shaft. The rear end of the fixed shaft is fixed in the fixed base. A supporting plate is also fixed on the front end surface of the fixed base. Multiple spring adjusting assemblies are arranged on the supporting plate at an interval.

摘要： The present invention relates generally to furnace systems and more particularly, but not by way of limitation, to a split-ring assembly for sealing a junction between a catalyst tube and a furnace. In one aspect, the present invention relates to a ring-seal assembly. The ring-seal assembly includes a housing ring coupled to an outer surface of a furnace. The housing ring is disposed around a circumference of a tube proximate a junction with the furnace. The ring seal assembly further includes a brush seal that is at least partially disposed within the housing ring. The brush seal is disposed around the circumference of the tube. A plurality of brushes extend radially inwardly from the brush seal towards the tube.

摘要： A combustion tube mounting system releasably mounts a combustion tube to an aperture in the floor of a furnace housing. The combustion tube has a base assembly with a cam and can be manually or automatically unlocked by cam pins in the floor for selectively engaging the cam for lowering the combustion tube from the floor of the furnace. When a new combustion tube is placed on the lower seal assembly and raised, it automatically aligns and engages the upper furnace seal and engages cams on the floor of the furnace housing which lock the combustion tube in place as it is introduced into the furnace.

摘要： The invention relates to a roller hearth furnace for heating workpieces, comprising at least one furnace chamber for receiving the workpieces, the chamber having at least two lateral furnace walls. At least one transport roller for transporting the workpieces through the furnace chamber is arranged inside the furnace chamber, and each of the furnace walls has at least one opening through which the transport roller can be guided. At least one rolling bearing unit is arranged on each of the outer sides of the furnace walls, said rolling bearing unit being designed to accommodate and support the transport roller outside the furnace chamber. The roller hearth furnace comprises a flushing system for the rolling bearing unit, said flushing system being designed to conduct a flushing gas through the rolling bearing unit, wherein the flushing gas can be conducted from a side of the rolling bearing unit facing away from the furnace wall through the rolling bearing unit and through the opening of the furnace wall into the furnace chamber of the roller hearth furnace. The invention further relates to a method for heating workpieces in such a roller hearth furnace.

摘要： A continuous annealing furnace for annealing steel strips that is a vertical-type annealing furnace is configured so that part of gas inside the furnace is drawn and introduced to a refiner disposed outside the furnace including an oxygen removing apparatus and a dehumidifying apparatus, oxygen and moisture contained in the gas are removed to lower the dew point of the gas, and the gas having a lowered dew point is put back into the furnace. At least one gas inlet through which gas is drawn from the furnace into the refiner is disposed in the vicinity of the entry side of the furnace at a distance of 6 m or less in the vertical direction and 3 m or less in the furnace-length direction from the steel-strip-introduction section located at the lower part of the heating zone.
