Lead, aluminium, zinc three-plate automatic temp.-controlled method lip

Abstract

A sort of auto-temperature-control metal casting nib is disclosed, which comprises two casting nib plates, which suitable for casting and rolling of lead, aluminum, zinc plate. The invention's character as follows, the metal casting nib comprises plates parallel upper and down made from cast iron, steel plate, copper and aluminum material, which has an automatic temperature-control device. Between the two plates there is a flow-guide wedge. The melten liquid outlet gap height of the parallel metal plates can be regulated. The top plate retracts 2mm comparable to the bottom plate whose outer edge directly contacts the discharge roller. The auto-control device is oblong or block shape carborundum heating plate, fitted with thermocouple and temperature sensor, externally connected with low voltage power supply and temperature controller and the outer layer is heat-insulation material. Advantages: it is not easy to be damaged, can automatically control temperature, simple process, high quality and low cost.

Description

technical field [0001] The invention belongs to metal casting and rolling technology and equipment, in particular to an automatic temperature-controlling metal casting nozzle suitable for the casting and rolling stages of three kinds of plates of lead, aluminum and zinc. Background technique [0002] At present, the casting nozzles in the metal casting and rolling stage are mostly made of aluminum silicate insulation materials. When the molten metal passes through the casting nozzles and is cast and rolled into a plate shape, the temperature of the casting nozzles is often unsuitable and the structure is not reasonable enough. There are often dimensional defects in the rolled plate shape, and the casting nozzle is easily damaged and cracked, easily absorbs moisture, reduces the heat preservation effect, and is difficult to complete multiple uses for a long time, resulting in high production costs, complicated processes, and unstable product quality.

[0002] At present, the casting nozzles in the metal casting and rolling stage are mostly made of aluminum silicate insulation materials. When the molten metal passes through the casting nozzles and is cast and rolled into a plate shape, the temperature of the casting nozzles is often unsuitable and the structure is not reasonable enough. There are often dimensional defects in the rolled plate shape, the nozzle is easily damaged and broken, and it is easy to absorb moisture, which reduces the heat preservation effect and makes it difficult to complete long-term multiple uses, resulting in high production costs, complicated processes, and unstable product quality.
