Oxygen-free copper strip horizontal electromagnetic casting device

Abstract

The invention relates to an oxygen-free copper strip horizontal electromagnetic casting device and belongs to oxygen-free copper strip production and processing matched equipment. The oxygen-free copper strip horizontal electromagnetic casting device comprises a crystallizer shell, a medium-frequency power supply, an induction coil, an electromagnetic oscillator, a shielding cover, a cooling water tank, a bottom die and a pouring mechanism; the pouring mechanism consists of a tundish and a pouring gate plug; the tundish is arranged on the upper part of the crystallizer shell; the bottom of the crystallizer shell is provided with a pouring gate; the pouring gate plug is arranged in the pouring gate; the tundish is communicated with the upper part of the crystallizer shell through the pouring gate; the upper part of the crystallizer shell is provided with the induction coil; the electromagnetic oscillator is connected with the induction coil; the induction coil is connected with the medium-frequency power supply; the induction coil is formed by winding pure copper of which the section is rectangular; the circulating cooling water is filled in the hollow part of the induction coil for the primary cooling; a cooling water box and a shower pipe are arranged on the lower part of the crystallizer shell, and spray water to cool the crystallized stripped copper blank for the secondary cooling; and the bottom of the crystallizer shell is provided with the bottom die.

Description

technical field [0001] The invention relates to an oxygen-free copper strip horizontal electromagnetic casting device, which belongs to supporting equipment for the production, processing and manufacturing of the oxygen-free copper strip. Background technique [0002] Because copper and copper alloys have many excellent properties, they are widely used in various sectors of the national economy, such as machinery, electronics, automobiles, electric power, communications, transportation and light industry sectors. The consumption of copper strips is very large. In 2009, the statistical production capacity of copper strips in my country was 1.435 million tons, the actual production capacity was 900,000 tons, and the capacity utilization rate was 63%. In that year, the imported copper strips were 350,000 tons, and the exports were about 20,000 tons. showing a trend of rapid increase year by year. However, the production capacity of general products in my country has been overcap...

Problems solved by technology

In recent years, oxygen-free copper materials with high thermal conductivity, high electrical conductivity, high density, low gas content and excellent mechanical properties are the basic materials in cutting-edge fields such as vacuum electronics. In this product field, only a few manufacturers in my country use small-tonnage vacuum melting production method, and the production volume is small, the equipment structure is complex, the maintenance is difficult, and the shortcomings of low yield are difficult to meet the needs of my country's supporting industries.

The oxygen-free copper strip casting equipment is relatively backward, and the quality of the copper strip produced cannot meet the requirements
