DE4405352A1 - Roller conveyor transport of hot flat metal product - Google Patents

Abstract

In a method of transporting a hot thin steel or other metal flat product on a roller conveyor, product travel on the conveyor is stabilised as soon as possible after product shaping/heating by curving the product across its width and conveying it in this state until it is forcedly further transported and/or cooling it to achieve a stiffness sufficient to ensure that it remains in non-rubbing contact with the horizontal rollers during further travel on the conveyor. Also claimed is a roller conveyor arrangement for carrying out the above method.

Description

It is known that hot / warm, flat production goods small thickness when passing on the roller table u. a. therefore too Disruption leads because there is increasing throughput speed tends to lift off the roller table ("go up"). These disruptions lead to dangers for the workforce, too Damage to the systems, loss of generation Quantity and considerable loss of production time.

The invention specified in claims 1 and 2 is the problem underlying, especially the 'going up' largely with increasing throughput speed impossible to make and the dangers involved and Not to let losses arise.

This problem is solved by the in claims 1 and 2 listed characteristics, the crowning of the production goods over a defined roller table length.

The advantages achieved with the invention are in particular in avoiding operational accidents, malfunctions and -Damage, in increasing the yield and increasing the Production quantity. The cost and remodeling time for that Implementation of the training mentioned in claim 2 Roller tables are low.

Advantageous embodiments of the invention are in the patent pronounced 3 and 4.

Embodiments of the invention are in the drawing shown schematically.

In the diagrams, the production goods are labeled ( 1 ) and the rolls are labeled ( 2 ).

The height of the crowning depends on the quality, with a higher one It is low in heat resistance and higher in lower ones. The The height of the crowning is shown exaggerated in the diagrams.

Claims (4)

1. Process for the passage of a hot / warm, flat steel and metal production goods of small thickness on a roller table characterized in that the production goods after shaping / heating, to stabilize its run on the roller table as far as possible over the width of the goods and as long as it is cambered and runs until the material to be produced is again positively guided and / or by cooling the stiffness is reached, which is sufficient for it to remain in non-tearing contact with its horizontal rollers during the further course of the roller table. 2. Training the roller table to carry out the procedure according to claim 1 for crowning the continuous Pro production goods, characterized, that the rollers of the roller table, as early as possible according to the shape in the roll intended for crowning aisle length, alternating skew on the right and left adjustable, arranged. 3. Training according to claim 2, characterized, that the mantle of the rollers of the roller table in which to the bom the length of the roller table provided, convex in relation to the rolling stock and / or is concave. 4. Training according to claim 2, characterized, that the mantle of the rollers, especially with very wide Production goods, convex in the middle and to the Edge areas are concave or vice versa returns.
