Fan Segment

Product Description

The main function of the fan segment is to guide the billet pulled out from the support guide segment to prevent the billet shell from bulging and deforming under the static pressure of the molten steel. At the same time, the billet with the liquid core is continuously sprayed with water or gas-water atomization cooling, so that the billet continues to be sprayed and cooled until the billet is completely condensed and stopped; the billet is pulled out and straightened into a slab through the driving wheels installed on each fan segment; the fan segment also has the function of guiding, transporting and clamping the ingot rod for pouring and billet drawing. A complete fan segment is mainly composed of inner and outer arc structures, rod installation (including driving rod and free wheel), clamping guide device, driving wheel pressing device, stick gap adjustment device and water cooling, lubrication, hydraulic piping, etc.

Some fan-shaped segments are also equipped with two side structures, which are fixed on the outer arc structure, and the mixed seam adjustment device is fixed on the side structure. The side structure has the function of guiding the upper structure. A lifting shaft for lifting the fan-shaped segment is installed above the side structure. The side structure and the outer arc structure are also equipped with guide shafts for replacing the fan-shaped segment.

The single continuous casting machine that constitutes the continuous casting line in continuous casting production is generally called a fan-shaped segment, which is generally divided into an arc segment (or a curved segment), a straightening segment, a horizontal segment, etc. According to the different billets, it can be divided into slab fan-shaped segments, square billet fan-shaped segments, and round billet fan-shaped segments. The most common ones in production are slab fan-shaped segments and square billet fan-shaped segments.

The fan-shaped segment of the continuous casting machine plays the role of supporting and guiding the billet. It is a device that directly contacts it during the billet cohesion process, and has a great influence on the surface quality and internal quality of the billet. The purpose of fan-shaped segment control is mainly to ensure accurate and stable roll gap according to process requirements.
