Abstract
A technology for lining lead plate with heat conducting method includes such steps as setting several fixing points on the internal surface of equipment, setting the fixing points on the lead plate corresponding to the fixing points on the internal surface of equipment, coating flux on the fixing points, baking a layer of tin (8-10 microns) on the fixing points, coating molten tin on the fixing points, hardening, lining the lead plate on the equipment, and heating to 185-205 deg.C for adhering the tin on the lead plate to the tin on the equipment.
Description
The present invention relates to a kind of is the process of lining with lead in the industrial equipment, pipe, pipe fitting of matrix with steel, cast iron.
Operations such as chemical industry, petrochemical industry, metallurgy for the corrosion-resistant purpose, need lining with lead in the industrial equipment, pipe and the pipe fitting that with steel, cast iron are matrix.The method of lining with lead is warded off nail fixation, bolt and hanger in place, pressing plate or press strip fixation, plumbous rivet fixation and welding rivet fixation.All there is the problem that speed of application is slow, difficulty big, construction quality is not high in these methods, when especially the patching stereotype is faced upward at the top of equipment, no matter adopt which kind of fixation lining with lead, all must before installing, equipment weigh lining in the hand, or top cover hung opening turns over welds, to the construction of just can't welding in the overhead position of mounted equipment.In addition, adopt bolt and hanger in place and pressing plate or press strip fixation lining with lead,, will be affected if when carrying out compound lining in the equipment.And when adopting plumbous rivet fixation lining with lead, the integrality of apparatus casing and pressurized performance all can be affected.
Adopt above-mentioned several method lining with lead, for negative pressure equipment and the equipment that has uniform temperature to require, as not carrying out compound lining, the stereotype that is served as a contrast just is easy to produce hollowing even come off.
Purpose of the present invention is exactly the problem that exists at said method, proposes that a kind of speed of application is fast, liner plate adhesion strength height, reduces the lining with lead process of difficulty of construction greatly.Adopt this method to need not the equipment top cover hung to open to turn over, can carry out lining with lead top cover.
The objective of the invention is to be realized by the following technical programs:
On the inner surface of equipment, establish the plurality of fixed point, establish on the stereotype with the equipment inner surface on the corresponding fixing point of fixing point, coated with flux on the fixing point.On the fixing point of equipment inner surface, iron last layer tin, tin thickness is 8-10 μ m, on the fixing point of stereotype, coat the Xi Shui that is dissolved again, tin thickness is after 8-10 μ m treat that the tin hydraulic is solid, stereotype is served as a contrast on equipment, and make that the fixing point on the fixing point and equipment matches on the stereotype, at device outer surface each fixing point is heated at last, the temperature of fixing point reaches 185 ℃-205 ℃ on equipment, tin on the stereotype and the tin on the equipment are bonded together, stereotype after will descending the piece stereotype then and fixing welds together, and presses the preceding method construction, has all served as a contrast until equipment inner surface stereotype.
Technical characterstic of the present invention and good effect:
Technology of the present invention is simple, grasps easily.During sidewall patching stereotype, no matter much equipment all need not to carry out on roll packer.To mounted equipment, no matter the great top cover of diameter, the liner stereotype does not need top cover hung opens the construction that turns over.The outstanding feature of the present invention is that speed of application is fast, and speed of application is more than 5 times of existing fixed method, can replace the existing plumbous method of warding off, and be to ward off more than 50 times of plumbous method indirectly, and adhesion strength is considerably beyond the adhesion strength of present various construction methods.
Accompanying drawing and description of drawings:
Accompanying drawing is that 1 is stereotype, the 2nd among the figure by the schematic diagram of the stereotype lining after the present invention's construction with the equipment bonding, apparatus body, 3 and 3 ' and be fixing point.
Below in conjunction with accompanying drawing narration embodiments of the invention.
On the inner surface of apparatus body 2, establish plurality of fixed point 3 ', fixing point 3 ' shape, size and mutual alignment identical with existing lining with lead fixing means, establish and the corresponding fixing point 3 of fixing point on the equipment inner surface coated with flux on the fixing point on the stereotype 1.On apparatus body 2 inner surface fixing points, iron last layer tin, tin thickness is 8 μ m, on the fixing point of stereotype 1, coat the Xi Shui that is melted, tin thickness is 8 μ m, after treating that the tin hydraulic is solid, stereotype is served as a contrast on equipment, and make the fixing point 3 on the fixing point 3 and equipment on the stereotype 1 ' corresponding one by one, and at device outer surface each fixing point being heated then, the temperature that is heated to fixing point on the equipment is 185 ℃, tin on the stereotype 1 and the tin on the equipment 2 are bonded together, then, the stereotype after will descending the piece stereotype again and fixing welds together, and presses the preceding method construction, so go down, all served as a contrast until equipment inner surface stereotype.
Claims (1)
1. the process of a heat transferring lead plate lining, establish the plurality of fixed point on the inner surface of equipment, it is characterized in that establishing on the stereotype with the equipment inner surface on the corresponding fixing point of fixing point, coated with flux on the fixing point, on the fixing point of equipment inner surface, iron last layer tin, tin thickness is 8～10 μ m, on the fixing point of stereotype, coat the Xi Shui that is melted again, tin thickness is after 8～10 μ m treat that the tin hydraulic is solid, stereotype is served as a contrast on equipment, and make that the fixing point on the fixing point and equipment matches on the stereotype, and at device outer surface each fixing point being heated, the temperature of fixing point is 185 ℃～205 ℃ on the equipment, tin on the stereotype and the tin on the equipment are bonded together, to descend piece stereotype and the stereotype of fixing to weld together then, press the preceding method construction, all serve as a contrast until equipment inner surface stereotype.
