Problems solved by technology

At present, there are many ways to strengthen the surface of the copper plate of the crystallizer. Among them, the flame spraying method using nickel-based alloy particles as the main spraying material is generally seldom used at present. The bonding strength has not been high, and it is very easy to affect the use effect of the crystallizer copper plate
Secondly, because nickel-based alloy materials are prone to coating particles sticking to the inner surface of the nozzle and cannot work stably for a long time, the nozzle of the spray gun needs to be cleaned frequently, which affects the efficiency of spraying work and the quality of spraying work

Embodiment Construction

[0010] A method of supersonic flame spraying crystallizer copper plate according to the present invention comprises the following method steps: first, the surface of the crystallizer copper plate is cleaned and sandblasted with a conventional cleaning process; secondly, nickel-based 50% to 95% alloy particles, and add 5% to 50% alumina particles to mix evenly to obtain the required spray coating; then, put the spray coating into the supersonic spraying equipment and spray the surface of the crystallizer copper plate according to the conventional procedure Go ahead and spray. In order to enable the crystallizer copper plate to obtain a higher quality coating surface, the preferred mass percentages of the sprayed coatings obtained by the above mixing are respectively: 80% to 92% of nickel-based alloy particles and 8% to 20% of aluminum oxide particles; The optimum mass percentages are: 90% of nickel base alloy particles and 10% of aluminum oxide particles. In this way, the pres...

Abstract

The method to spray copper plate of crystallizer with supersonic-speed flame comprises: cleaning and sand blasting to the copper plate with conventional cleaning tool; mixing 50~95% nickel alloy particle and 5~50% alumina particle to obtain require coating material; putting the coating into supersonic-speed spraying device for blasting the crystallizer surface. This invention improves the bond strength of coating greatly to ensure quality, and overcomes the problem that alloy particle bonds spray nozzle.

Description

technical field [0001] The invention relates to a method for spraying crystallizer copper plates with supersonic flame. Background technique [0002] Supersonic flame spraying technology is especially suitable for spraying some cermets due to its advantages of fast flame speed, low temperature, high coating bonding strength, no decomposition of coating components, simple process and convenience. At present, there are many ways to strengthen the surface of the copper plate of the crystallizer. Among them, the flame spraying method using nickel-based alloy particles as the main spraying material is generally seldom used at present. The bonding strength has not been high, and it is very easy to affect the use effect of the crystallizer copper plate. Secondly, because nickel-based alloy materials are prone to coating particles sticking to the inner surface of the nozzle and cannot work stably for a long time, the nozzle of the spray gun needs to be cleaned frequently, which aff...
