The hot rolling mill cooling bed is the working table for cooling rolling products (threaded steel, circular steel, steel pipe, etc.) effectively in metallurgical rolling industry. The hot mill cooling bed is composed of a mechanical transmission system, water cooling system, the working table of the cooling bed, fixed support, etc. The main cooling beds are the pull-out cooling bed, walking beam cooling bed, pull-claw cooling bed, transport chain cooling bed, rolling disc cooling bed and so on.
The hot rolling mill cooling bed is one of the indispensable auxiliary equipment in medium and small bar rolling mill workshop. Its function is to cut the rod of double length by flying shear after rolling, transport and unload it to the rack of cooling bed for cooling so that its temperature can be lowered from 900 to 100-300 degrees. Then it is collected by the cooling bed blanking device and sent to the output roll table in groups, and then sent to the cold shear by the output roll table to be cut into fixed-length finished products. The design quality and installation accuracy of the cooling bed directly determine the final quality of the product.
The hot rolling mill cooling bed consists of three parts: the feeding device of the cooling bed, the sawtooth step-by-step body of the cooling bed, the feeding device of the cooling bed and the output roller. Among them, the cooling bed material device is the difficulty in the design of the cooling bed, and it is also the throat equipment.
The main hot rolling mill cooling beds are the pull-out cooling bed, walking beam cooling bed, pull-claw cooling bed, transport chain cooling bed, rolling disc cooling bed and so on.
Walking Beam Cooling bed
Walking beam cooling bed is important auxiliary equipment in the process of pipe and bar continuous rolling production line. It is an indispensable and important component in the production process. Waking beam cooling bed has the advantages of high speed, continuous rolling, slitting rolling, automation and so on. It has been widely used in cooling rod, tube, and some small cooling equipment. Increased production efficiency. However, because the structure of the walking beam cooling bed is complex and the tonnage needed to be set in use is large, the difficulty of manufacturing and installation of walking beam cooling bed is also increased.
Automatic TMT Rebar Rolling Mill Cooling Bed
Used for purpose of uniform air-cooling of TMT bars and transporting the same in a phased manner.
This transporting is done from the entry of the cooling bed to the discharge side. In this, the front end of the bars is also leveled at the discharge side and a fixed number of bars are sent for final length cutting by cold shear and bundling.
Designed considering the finishing mill stand of the mill and cooling time required for the various sizes of the bar.
