Skids used to support a workpiece in a reheat furnace are adjustably positioned and anchored to resist longitudinal movement of the skids while workpieces are moved therealong. The anchor apparatus includes a rectangular housing, one end of which is attached by an anchor rod to a foundation while the other end has an aperture to pass an anchor rod into the space between the side walls of the housing. An internal bearing wall subdivides the space in the housing into two cavities. A bearing plate on the movable anchor rod in one cavity is forced by a piston and cylinder assembly to move the rod into the housing to thereby adjust the position of a skid to which it is attached. Shim plates are placed in the second cavity within the housing between an internal wall and a bearing flange attached to the movable anchor rod. Other shim plates are inserted between the end wall of the housing and the actuator to maintain an effective range of adjustment by the actuator.

Spaced-apart skid frames support workpieces in a reheat furnace. Each skid frame includes a plurality of spaced-apart rails arranged to extend along the path of travel of the workpieces in the furnace for engaging the underside faces of the workpieces. A tubular top cord member carries rail members. Two horizontally-spaced tubular lower cord members extend parallel and below the top cord member. Tubular web members extend angularly between joints which intersect with the top and lower cord members to form a lattice structure having triangular open spaces between the top cord member in each of the lower cord members for passage or radiation to heat the underside faces of workpieces along either side of the skid frames. Coolant is supplied to each of the top and lower cord members and the tubular web members to prevent overheating.

A steel workpiece reheating apparatus and method for raising the temperature of a thin continuously-cast hot workpiece to a required working temperature without causing harm to the workpiece. The apparatus includes a high intensity heating chamber provided at the charging end of a reheat furnace structure which briefly and intensely heats the workpiece above its melting temperature before it enters the remainder of the reheat furnace. The provision of the high intensity heat chamber at the charging end of the reheat furnace structure permits substantial reduction in the length normally required of the reheat furnace to raise the workpiece to the desired working temperature and thus reduces the time spent by the workpiece in the reheat furnace. The high intensity heating chamber uses in its combustion process combustion air preferably preheated by a heat recovery system associated with the heat derived from the combustion occurring within other portions of the reheat furnace. Upon combustion of the preheated combustion air with an appropriate fuel, temperatures above the melting temperature of the steel are achieved within the high intensity heating chamber.

While the leading end of a first heated workpiece is processed in a rolling mill, the trailing end is joined to the leading end of a second heated workpiece. End portions of the workpieces at the gap therebetween are held by clamp members at a spaced-apart location so that both workpieces advance at the same speed toward the rolling mill. The end portions of the workpieces are cleaned to remove scale and then a mold is positioned to span the gap and contact the end parts of the workpieces. Liquid-weld metal is introduced into the mold and allowed to at least partially solidify before the mold is removed while the rolling operation continues. The weld metal substantially solidifies and is passed through the rolling mill.

A hearth cleaning apparatus includes a wheeled car movable along a floor at the side wall of a reheat furnace wherein metallic workpieces are heated while they are advanced along the furnace hearth. The car is latched to the side wall of the furnace at any one of the normally-closed openings therein. An inverted U-shaped spacer slab is passed through the furnace between two workpieces for access to the hearth. An elongated digging bar which may be cooled by the internal flow of water is supported by the car and advanced through an opening in the side wall of the furnace to engage and loosen slag or other materials adhered to the soaking hearth while exposed by the spacer slab. The car includes a vernier elevation adjustment for the digging bar at the point of support adjacent the furnace and a course elevation adjustment for the digging bar at the opposite end of the car. The digging bar is propelled along the furnace hearth by a pair of pinch rolls. An eccentrically-pointed end on the digging bar is rotated by skewing one of the pinch rolls.

A dual flow distribution header system in which the flow is divided into two paths before the distribution header but after a metering device. The flow is controlled by separate butterfly valves in each path, whereby the control function is magnified and becomes more precise in each path. The invention is particularly adapted for use with industrial heating furnaces employing dual burner systems.

Walking beam assemblies used to advance workpieces in a reheat furnace include upper and lower runs of coolant pipes spaced and joined together by web plates to extend along each of the opposite lateral sides of a body of refractory that contacts the workpieces. The web plates support clip members that have a bent midportion to wrap around the upper run of the coolant pipe. A leg section of each clip member extends along the side of the refractory material to an elevation spaced below the workpiece-engaging face of the refractory. Support members including gusset plates are carried by the refractory support member to engage the lower run of the coolant pipe and extend along the web plates for support.

A process for selective vaporization of oxides from recovered waste dust collected from a bag house. Pellets are formed from the waste dust and dried to permit charging in an oxidizing chamber wherein an oxidizing atmospheric is maintained. The chamber is heated to a temperature sufficient to vaporize lead oxide and, if present, also oxides of cadmium, potassium and sodium. The vapors are cooled and separated from furnace gas. The residual oxidized mass is cooled after removal from the oxidizing chamber and fed into a reduction chamber wherein a reducing atmosphere is maintained. The reduction chamber is heated to a temperature of between 1800 and 2000 degrees Fahrenheit to reduce zinc oxide and form zinc vapors which are cooled and separated from furnace gas. Lead oxide particles recovered from the oxidizing process are reduced to lead.
