Definitions
- the invention relates to a pusher furnace with rails and with sliding shoes guided thereon, which carry the items to be transported through the furnace, wherein sliding supports are provided on the rails, which have grooves for absorbing material abrasion
- Shock furnaces are mostly used for the annealing treatment of bars, e.g. aluminum bars. Such bars can weigh several tons and are therefore usually moved with the help of hydraulic pushing devices
- EP 0 108 047 B1 discloses a pusher furnace, the rails of which are provided with a large number of sliding elements. These sliding elements are - each sliding element for themselves - inserted in flat recesses on the surface of the rails, one behind the other and next to one another, and protrude from the surface of the rails These sliding elements can have surface grooves that run diagonally to the longitudinal direction of the rail to absorb material abrasion. With their short sides, which are designed to be normal to the longitudinal direction of the rail, the plate-shaped sliding elements form smooth abutting edges for the sliding shoes that can be displaced on the sliding elements.
- the object of the present invention is now to provide a pusher furnace of the type mentioned at the outset which, with a simple structure, enables jerk-free displacement of highly loaded sliding shoes
- the sliding supports are plate-shaped, they each completely cover the rails in their width and are provided on their upper sides with arrow-shaped grooves running in the longitudinal direction of the rails for receiving material abrasion and that several sliding supports are formed arrow-shaped butt joints are lined up, the cross-section of the butt joints essentially corresponds to that of the grooves.By designing sliding elements that cover the entire rail width and have arrow-shaped grooves, jerky impacts when hitting sliding elements are significantly reduced.
- arrow-shaped butt joints make them wider Transition area created in which one rail can hardly move laterally compared to another. Jerky impacts due to height differences between two rails are alleviated by the arrow-shaped transition area This means that the durability of rails and shoes can be significantly increased
- the sliding supports can be screwed to the rails.
- This screw connection is particularly suitable for high-quality sliding supports.
- the rails and the sliding supports can each be connected in one piece
- the rails and the sliding supports can each be connected in one piece as a cast piece.
- the one-piece design for example in the form of a cast piece, enables simple manufacture, assembly and disposal
- the sliding supports can be made of cast steel
- the pusher furnace can be designed in such a way that the tips of the arrow-shaped grooves of the sliding supports are directed against the direction of transport. This improves the absorption and discharge of material abrasion
- FIG. 1 shows a pushing furnace according to the invention schematically in cross section
- Fig. 2 shows a rail with an attached slide shoe
- Figure 1 shows a pusher furnace 1 with a furnace chamber, in which heating burners 2 are arranged on both sides.
- the pusher furnace is provided with a ceiling fan 3 and gas baffles 4 for the circulation of the furnace gases.
- On the bottom 5 of the pusher furnace 1 there are 6 rails in two rows on nozzles 7 attached with sliding supports 8, which protrude into the zone protected on both sides by the gas baffles 4 from the heating burners 2
- Figure 2 shows a U-shaped rail 7, on which a plate-shaped sliding support 8 is mounted, the width of which is greater than the width of the rail 7, so that a protruding flange 11 is formed on each of the two longitudinal sides of the rail 7, among which both Sides of a sliding shoe 9 which slides over the sliding support 8
- the area of the sliding shoe 9 which rests on the sliding support 8 is essentially cuboid in shape.
- a plurality of sliding supports 8 can also be mounted in series be fastened over the joint of two rails 7.
- grooves 12 are arrow-shaped against the transport direction so that a sliding shoe 9 sliding over the sliding supports 8 is not jerkily loaded when it hits a groove edge
- the two ends are 13, 1 4 of the sliding support 8 are designed such that they likewise form an arrow-shaped groove with the ends of the sliding support of an upstream or downstream similar rail, not shown here
