Abstract
The invention provides a processing technique for an anticorrosion pipe plate of a tube shell type heat exchanger. The non-ferrous metal with anticorrosion property is molten and then is tightly and integrally combined with a carbon steel alloy, so that the problem of easiness in corrosion of the pipe plate of the heat exchanger is solved. The processing technique for the anticorrosion pipe plate of the tube shell type heat exchanger is characterized by comprising the following steps: using a medium frequency heater for heating a processed pipe plate, namely, a substrate carbon steel pipe plate, to be above 890 DEG C of the melting point of the covering material iron brass, and then starting to use a first auxiliary heating oxy-acetylene flame and a second auxiliary heating oxy-acetylene flame for auxiliary heating and melting the covering material iron brass, thereby causing the covering material iron brass to be under a liquid state and flow in a sunken space pre-processed on the processed pipe plate, namely, the substrate carbon steel pipe plate. The invention has the beneficial effects that the processing technique for the anticorrosion pipe plate of the tube shell type heat exchanger is an energy-saving production technique which is developed by gathering multi-subject knowledge on the basis of metal material science, welding and heat treating and automatic control for medium frequency heating technique and equipment.
Description
Technical field
The present invention relates to heat exchange process manufacturing field of equipment peculiar to vessel, particularly relate to the processing technology of a kind of shell-and-tube exchanger with anticorrosion tube sheet
Background technology
The present invention relates to the processing technology (flying copper) of the anticorrosion tube sheet of a kind of shell-and-tube exchanger, make it melt by heating the non-ferrous metal possessing decay resistance also to combine closely integral with the carbon steel possessing intensity index, become the heat exchanger tube sheet simultaneously possessing intensity and decay resistance, to meet the manufacture needs of tube side heat transferring medium for heat exchanger during corrosivity object, and save nonferrous metal resource.
Summary of the invention
The problem to be solved in the present invention is to provide the processing technology of a kind of shell-and-tube exchanger with anticorrosion tube sheet, by separating the corrosion-prone problem of heat exchanger tube sheet by being closely as one with carbon steel alloy after the non-ferrous metal melting with decay resistance.
Technical scheme of the present invention is as follows: a kind of shell-and-tube exchanger processing technology of anticorrosion tube sheet, after it is characterized in that being heated to cover material iron brass 890 DEG C of above temperature of fusing point for processing tube sheet and base material carbon steel tube plate by use intermediate frequency heater, start the first auxiliary heating oxy arc and the second auxiliary heating oxy arc carry out auxiliary heating and melt cover material iron brass welding wire make its be in a liquid state generation processing tube sheet and base material carbon steel tube plate on flow in the dented space that processes in advance, period cover material iron brass welding wire automatic feeding confession fusing is used, cover material iron brass after fusing closely combines with base material carbon steel tube plate, form one possess decay resistance and meet the tube sheet of heat exchanger strength demand.
Beneficial effect of the present invention is: the present invention relies on the automatic control of Metal Material Science, welding and heat treatment, heating in medium frequency technology and equipment, be that a set multi-subject knowledge shares a kind of energy-saving processing technique developed, this technique effectively can improve the anticorrosion effect of carbon steel tube plate and reduce the waste of nonferrous metal resource.
