The caster tip for continuous casting is generally made of a low-density ceramic material that can withstand the wear and thermal shock associated with liquid aluminum contact, such as a ceramic fiber board formed into the necessary shape. Because of the low density of these materials, they have a low thermal conductivity and can provide […]
Casting nozzles have been made of various refractory materials. The part of the nozzle in contact with the molten metal is a refractory material composed of silica, asbestos, sodium silicate and lime. Although the refractory nozzle exhibits good thermal insulation and low heat capacity, it is not very uniform in terms of chemical composition and […]
During the assembly process of the roll caster feed tip, the gasket is also permanently fixed to the top or bottom member by any means. The spacers extending through these guides are made of refractory material that is not wetted by molten aluminum alloy. Most preferably, the guide and the spacer are adapted to extend […]
By combining a pair of slender feed nozzle components with a non-corrosive cushion, a molten metal feed nozzle for a continuous roll casting machine is made. The feed nozzle members are spaced a sufficient distance apart to allow molten metal to pass through the downstream edge to engage the surface of the continuous casting roll. […]
Caster nozzle is the key component of aluminum strip continuous casting and rolling mill, its quality directly affects the quality and output of aluminum strip. Special treatment of caster nozzle material can effectively prevent molten aluminum from corroding the casting nozzle and avoid carbonization. Fracture tissue is a fine and uniform layered fiber structure, which can […]
Aluminum silicate casting tip, also known as casting nozzle, is a key component to transport and distribute metal body directly to casting roll during continuous casting and rolling. It consists of upper and lower fans, several gaskets and side ears. Aluminum silicate casting tip is a refractory board made of ceramic fiber and silicon aluminum […]
The structure of the feed nozzle is diverse, which can be selected according to the respective process and equipment conditions. The open size of the gasket can change with the change of the plate width. During processing, try not to have sharp corners and dead corners in each runner and block. When assembling the gasket […]
At present, the customers have higher and higher requirements for the surface quality and finish of foil, so they put forward higher requirements for the surface quality of cast rolling strip. The surface quality of cast rolled strip is one of the key factors affecting the surface quality of aluminum foil products. In order to […]
In order to cooperate with the cooling and increasing speed of casting and rolling, based on the increase of the nozzle roll gap, the flow pattern of the nozzle must be improved to make the flow field, temperature field and concentration field in the tip cavity uniform. Due to the cooling and increasing speed of […]
Due to the uneven contact surface between the casting nozzle and the upper and lower rolls during installation, the casting nozzle partially contacts the roll surface tightly, resulting in strong friction, obvious traces on the roll surface, and white stripes on the plate surface. Therefore, when installing the casting nozzle, you must pay attention to […]
