摘要:
In order to be able to carry out a multiplicity of continuosly recurring activities at a continuous casting plant having at least one multifunction robot for implementing a plurality of different process-controlled or automated interventions at the continuous casting plant, at least one working region at the continuous casting plant and at least one multifunction robot assigned to each working region. The multifunction robot is arranged on a pivotable arm at a rotary column fastened to the pouring platform of the continuous casting plant and the robot can be pivoted with the pivot arm between a retraction position and a working position. The robot is also movable with respect to its arm.

In order to effectively stop noises in the interior of a vehicle occurring to relative movements between individual components or a component and associated support part, it is proposed to coat them with a lacquer at the contact points.
摘要:
A roll (1) for supporting and conveying hot material, including a roll element that has a roll jacket (2) made of a basic material and a wear coat which is applied to the basic material by means of a surface welding process (4) using a welding additive which surrounds the surface of the roll jacket. In order to increase the service life of the wear coat, improve the resistance to wear, and reduce the cost for producing the welded-on surface. The basic material of the roll jacket (2) is steel and contains up to 0.45 percent of C. The welded-on surface (4) is designed as a single-layer weld, and the wear coat contains 12.5 to 14.0 percent of Cr at least in an external zone that surrounds the surface of the roll jacket. Also disclosed are a method for producing the roll (1), a method for repairing a used roll (1), a welding additive and a welding rod for producing the welded-on surface.
摘要:
Aqueous emulsions of organopolysiloxanes functionalized with a limited amount of aminoalkyl-functional end groups and silicone resins are storage stable, yet capable of adequate crosslinking upon application to substances to be hydrophobicized.
摘要:
A device for interchangeable connection of a casting tube to a spout of a melt vessel with a sliding closure fastened on a melt vessel. The closure is formed by at least one stationary closure plate and a closure plate that can be displaced relative thereto, wherein the displaceable closure plate is coupled to a sliding drive system and carries the casting tube. To improve the changeover process of a casting tube and to make it safer, the displaceable closure plate carries a connecting ring for the centered accommodation of the casting tube and the displaceable closure plate carries a changing device for the casting tube. The changing device is synchronously displaceable with the displaceable plate. A tensioning device presses the casting tube onto the displaceable closure plate.
