Method and device for thermal treatment of rails

FIELD: metallurgy. SUBSTANCE: proposed method comprises the steps that follow. Rail head, web and foot are preheated from austenitising start temperature to that of its end. Additional heating by heat cycling in the region of phase α-γ transitions with cooling of rail cross-section to temperature that provides for fine perlite structure. Note here that heating is controlled continuously or in steps by separate heaters so that temperatures over rail cross-section are leveled. After cooling, self-tempering is performed at temperature sufficient for stress removal. Now, additional differential cooling of rail is performed to ≤250°C. Final cooling is made to temperature below 60°C. Proposed device comprises induction heaters with preliminary and final heating zones, cooling modules with the unit of control and adjustment of cooling parameters, differential and final coolers, self-tempering zone.

The oven is essentially characterised in that it includes heating means and means for moving the components to be treated, these means including a bed 96 of wires 60, 61, 62, first and second means for holding respectively the two ends of the said bed of wires, as for example rollers 30, 31 mounted so as to rotate respectively on two shafts 38, 39, means 50 for controlling the movement of the first means for holding an end of the bed of wires, and means 44, 45, 46, 66 for controlling the movement of the second means for holding the other end of the bed of wires, as a function of the movement of the first holding means. Application, especially, to the production of through-type ovens for melting, reflowing, drying, curing (firing) or polymerising of pastes, solder pastes, and resins used in electronics, microelectronics, etc.

Hot rolling mill with reheat furnace - heats continuously cast material for continuous charging of rolling mill

The heating arrangement is used for heating workpieces by reheat furnace of a rolling mill. The arrangement incorporates a casting process for casting of the workpieces to be rolled and also the rolling train connected directly by the heating process. Workpieces are rolled at a speed greater than that of the casting operation. Heat losses in the compact reheat furnace are reduced. The reheat furnace ensures stable operation and it is readily incorporated into a hot rolling train connected directly by the heating process. Workpieces are rolled at a speed greater than that of the casting operation. Heat losses in the compact reheat furnace are reduced. The reheat furnace ensures stable operation and it is readily incorporated into a hot rolling mill. The workpieces are heated in the longitudinal direction in a first and second heating chamber of the furnace in the travelling direction of the workpieces. The first and second heating chambers are alternately charged with the workpieces arriving from the continuous casting operation. Workpieces are placed successively into the second heating chamber after the first heating chamber has been continuously charged and filled with workpieces.

Heat treatment furnace

Device and method for heat-treating steel wires

The invention relates to a furnace (1) for heat-treating at least one elongated, in particular metal object such as one or more wires (2), in particular steel wires, in a continuous process, comprising a furnace entrance (3) and a furnace exit (4) and one or more furnace sections (5), which extend between the furnace entrance (3) and the furnace exit (4) and form a first shaft (8), wherein in the furnace (1), in particular in the first shaft (8), one or more heating elements (6) for setting a temperature in the one or more furnace sections (5) are arranged, and wherein the elongated, in particular metal object can be transported along the first shaft (8). According to the invention, at least one second shaft (9) connected to the first shaft (8) and at least one fan (7) are provided, wherein an atmosphere in the furnace (1) can be circulated by the fan in the circuit along the first shaft (8) and the second shaft (9). The invention further relates to a module for heat-treating at least one elongated, in particular metal object such as one or more wires (2), in particular steel wires, in a continuous process, and to a device comprising a furnace (1) and such a module, and to a method for heat-treating at least one elongated metal object such as one or more wires (2), in particular steel wires, in a continuous process.

Slab heating furnace

Preheating furnace for wire blooms - with divided girder support and transport mechanism

Wire blooms are supported across fixed longitudinal girders in a preheating furnace. Two sets of moving girders, offset relative to each other, and overlapping at the middle of the furnace, move the blooms along. Each set lifts only those blooms in its own half of the furnace at any time. The moving girders in one half of the furnace are aligned with the fixed girders in the other half, and retract into slots below their level. They are raised and lowered in sets alternately by carriages moving on opposed inclined planes, and moved longitudinally by tie-bars connected to a balance beam. Dividing the moving girders into two sets saves a considerable amt. of energy. As only half the furnace load is moved at a time the structure can be lighter, and as the two halves are balanced, and as one is raised the other is lowered, effectively only the half load plus an allowance for mechanical losses has to be raised and moved.

Drive unit for conveyors in walking-beam furnaces - using hydraulic by-pass control circuit to ensure smooth travel of beam

Drive unit for conveying heated material through a furnace, consists of a double-acting hydraulic cylinder contg. a piston connected to the conveyor and a distributor with outlet pipe (a) feeding the cylinder, and outlet pipe (b) feeding the piston side of the cylinder; the distributor inlet is connected to a source of oil under pressure, and a non-return valve is fitted in pipe (b). A by-pass is provided between pipe (a) and the section of pipe (b), between the non-return valve and the cylinder, the by-pass being fitted with a pilot non-return valve opposing the flow of oil from (b) to (a) when the oil pressure is below a specified value, and a control valve is provided to ensure flow when the specified value is exceeded. Used e.g. on walking beam- or moving hearth-furnaces. A smaller, simpler hydraulic circuit is used cf. conventional circuits.
