Problems solved by technology

This process requires two ladle containers, and requires that the different metals contained in the two ladle containers are difficult or partially miscible in the liquid state; in addition, because the two-roll mill used for rolling deviates from the spraying position of the atomized metal, the bimetallic composite When the belt enters the roll gap of the rolling mill, the deposited metal on the back belt has experienced a long cooling time and is in a solid state. The binding force of the person is not enough an

Embodiment Construction

[0047]The nozzle 1 is placed above two horizontally placed rolls 4 and 41, and the interior of the rolls 4 and 41 is cooled by water, and the two sides above the gap between the rolls 4 and 41 are provided with side sealing plates 15, spraying and rolling bimetallic sheets or strips The master strip is pre-tensioned by means of twin nip rolls and take-off or helper rolls.

[0048] The atomizing nozzle can be placed directly above the gap between the two rolling rolls to spray on the mother strip 11 .

[0049] The process steps are as follows:

[0050] 1) Preparation of liquid alloy: smelt the metal to be sprayed, and control the superheat between 50 and 200 °C;

[0051] 2) Preparation of the master strip: the master strip 11 is a hot-rolled coil or a cold-rolled coil;

[0052] 3) uncoiling and flattening the master tape 11;

[0053] a) Decontamination: remove the oil stain on the surface of the master tape 11;

[0054] b) Removing the oxide layer: removing the oxide layer ...

Abstract

The present invention relates to metal atomizing and spraying process and apparatus to produce thin bimetal plate or belt and belongs to the field of metallurgical technology. The present invention features that a nozzle is set over two horizontal rollers capable of being cooled with inside water and side sealing plates are set on two sides of the roller gap. The atomizing nozzle sprays high speed inert gas flow to crush liquid metal flow so as to form disperse semi-solidified metal grains sprayed to between the pre-treated base metal belt pre-stretched with one of the rollers and the other roller, and the deposited metal grains are adhered firmly onto the base metal belt at high temperature. The double roller rolling strengthens the combination between the base metal belt and the deposited metal to form excellent bimetal plate (belt). The present invention has the advantages of short technological process, compact apparatus structure, high combination strength, low power consumption, etc.

Description

1. Technical field [0001] The invention relates to a process and equipment for continuous production of bimetal thin plates and thin strips by metal atomization spraying, belonging to the field of metallurgy. 2. Background technology [0002] The composite and functionalization of metal materials is the main trend of the development of metal materials in the new century. Bimetal composite plate (strip) is a new type of metal composite material that combines two metal materials with suitable properties through temperature and pressure. It can give full play to the performance characteristics of each component according to the design requirements, and meet the requirements of modern industry for various properties of materials with its high strength, wear resistance, corrosion resistance and other mechanical, physical, chemical and other engineering properties. A single metal plate is no match for it. Bimetallic composite materials can play the role of measurement, overload ...
