Closable type automatic material throwing copper furnace cover used for continuous casting of copper and aluminum composite materials

Abstract

This invention provides a closable type automatic material throwing copper furnace cover used for continuous casting of copper and aluminum composite materials. The closable type automatic material throwing copper furnace cover used for continuous casting of the copper and aluminum composite materials comprises a sealing cover which is provided with a sealing device; the sealing device comprises a melting furnace cover and a heat preserving furnace cover; and the sealing cover is provided with an automatic material throwing device which is controlled by an electrical control device. The closable type automatic material throwing copper furnace cover used for continuous casting of the copper and aluminum composite materials is good in sealing performance, good in heat preservation effect, low in energy consumption, capable of achieving automatic material throwing, convenient to operate and high in safety. When a copper plate is added, a worker mainly performs operation through a switch on a remote controller, the labor force is saved, the production efficiency is improved, an electrical mechanism is controlled through a cylinder, and cost is low; and besides, a furnace cover material adding port is small, the material adding position is low, copper liquid cannot be splashed out easily, and safety is high.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and in particular relates to a sealable automatic feeding copper furnace cover for continuous casting of copper-aluminum composite materials. Background technique [0002] At present, the melting and holding furnace cover for copper alloy casting generally uses the traditional furnace cover or is designed as a normally open integral furnace cover. This type of melting and holding furnace cover has many disadvantages in the long-term use process: a. Poor airtightness. When the furnace cover is often open or the airtightness is not good, the air outside the furnace and the furnace are in a state of alternating flow. At this time, the copper liquid in the furnace can easily absorb harmful gases such as hydrogen and oxygen, which makes the castings prone to casting defects such as pores. Lead to a decline in product quality; b Manual feeding. When adding copper plates, workers feed m...
