Induction heating device for membrane type wall tube row surface spray welding layer alloy and process

Abstract

The invention discloses an induction heating device for a membrane type wall tube row surface spray welding layer alloy and a process. The device comprises a tube row walking supporting rack capable of supporting a membrane type wall tube row, a tube row walking supporting body arranged on the tube row walking supporting rack and capable of driving the membrane type wall tube row to advance on thetube row walking supporting rack, tube row heating induction coils arranged above the top of the tube row walking supporting rack and a heat insulating cover capable of detachably covering the membrane type wall tube row. Compared with the traditional technology, the surface coating alloy and a membrane type wall tube row matrix can be metallurgically bound, the whole membrane type wall tube rowis more uniformly heated, the production efficiency is improved, and the induction heating device and the process are suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of heat treatment of membrane-type wall tubes, in particular to an induction heating device and process for spray-welding layer alloys on the surface of membrane-type wall tubes. Background technique [0002] With the rapid development of urbanization and the continuous expansion of cities and towns, the amount of industrial waste and domestic waste has also increased sharply. Their disposal has become a major issue related to the sustainable development of urban civilization, and waste incineration power generation technology can maximize the realization of The harmless, volume reduction, stabilization and recycling of garbage can promote the healthy and civilized development of urbanization, so it has attracted more and more attention. In the actual engineering application of waste incineration power generation, the membrane wall tube row is an important heat exchange component (heat exchanger), and its heating surf...

AI Technical Summary

Problems solved by technology

In the actual engineering application of waste incineration power generation, the membrane wall tube row is an important heat exchange component (heat exchanger), and its heating surface is often corroded by high-temperature chlorine-containing sulfur-containing atmosphere and its molten salt during operation. The heating surface of the membrane wall tube row is often coated with a high temperature corrosion resistant coating to prolong its service life, but the surface coating of the current membrane wall tube row is prone to uneven heating during production, resulting in quality problems. Correspondingly, Production efficiency has also been reduced, unable to meet the needs of industrial production
