Abstract
The invention was involved in the preparation method of printing and dyeing of selvedge roll, printing roll and mill roll. General carbon steel was used as pipe and the process consist of the following steps: a) General carbon steel pipe was turned to form the roll. b) The surface of roll was implemented by frosted treatment. c) The static equilibrium test and alignment were done for the roll. d) Plasma spray coating to the roll surface was carried out. The spray coating material was complex rustless iron ceramic powder. e) The roll surface was burnished. The invention used high-energy plasma spray coating technology to produce complex ceramic coating on the surface of roll. So the corrosion resistance, wear-resisting property of roll were improved. Complex ceramic coating bonding with base firmly was formed on the surface of general carbon steel selvedge roll. So the surface hardness of roll was more than HRC 40, bond strength was more than 30MPa and the porosity was less than 5%, the corrosion resistance, wear-resisting property of roll were optimized, so they were used to substitute for integral rustless iron roll with obvious economic performance.
Description
Technical field
Fabric guide roll and the printing press complete processing with roller, roll etc. the present invention relates to print and dye.
Background technology
Three directions mainly are devoted in fabric guide roll research and production in the at present domestic and international dyeing machine:
(1) is devoted to strengthen the physical strength of roll body.Along with the printing and dyeing trend of constantly widening of breadth and some denims and military extraordinary cloth hightension, high unit mass, the printing and dyeing amount of finish of cloth is big, compares with traditional fabric guide roll, and fabric guide roll has been proposed major diameter, overlength requirement.Overwhelming majority solution: A, the former body thickness of increase; B, in former body, increase the keel bracing frame; C, employing stainless steel and the compound body of plain carbon stool machinery; D, in former body the poly-ammonium ester foaming material of filling.There is several problems: A in the employing of above technology, increases material usage, causes cost significantly to promote; B, increase technology difficulty, other technical indicator is difficult to reach; Reinforced effects is not obvious after C, the filling.
(2) be devoted to increase roll body surface flatness and abrasion strength resistance.Along with the printing and dyeing of the world and the ultra-fine ultra-thin lining of the domestic top grade of part, printing and dyeing fabric guide roll surface smoothness is required more and more high, a little face such as minute surface that reaches is arranged, traditional fabric guide roll is because the limitation of material, extremely difficultly reaches by processing means; Wear-resistant problem is for many years because the limitation of material itself, do not obtain fine solution always, some research approach is taked to increase wear resistant alloy in the body alloy material, but because metallurgical material enterprise is difficult to be difficult on satisfied or the cost control, right to use problem fails to solve, and just does some trials on the extraordinary roller of some short runs.
(3) be devoted to reduce product cost, enhance one's market competitiveness.Because dyeing machine belongs to a kind of sophisticated processing manufacturing industry in the world, particularly day, Ou Ji advanced manufacturing technology and OEM mode for many years descend on cost greatly; Taiwan products enters and the adding of joint venture in recent years, make market competition be growing more intense, all kinds of enterprises are saving starting material, are strengthening in share of market, the enterprise's scientific management and make an issue of one after another, but owing on the fabric guide roll processing technology breakthrough is not arranged, the space that reduces cost has been subjected to limitation, enterprise profit drops many times, and later stage research ability is difficult to form, and has seriously hindered technical progress.
Summary of the invention
The object of the invention is a kind of production of high-strength corrosive proof roller, has characteristics such as intensity height, flexing resistance is good, corrosion resistance is high, cost of goods manifactured is low.
The present invention is a body by general carbon steel, makes through following production stage:
A, Vehicle Processing general carbon steel pipe form roll body;
B, pair roller external surface are implemented texturing and are handled;
C, roll body is carried out statical equilibrium test, alignment;
Plasma spraying is carried out in d, employing pair roller surface, and spray material is the composite stainless steel ceramics powder;
E, polishing roll external surface.
The present invention utilizes the high energy plasma spraying technology at roller spare surface preparation composite ceramic coat, corrosion-resistant, the abrasion resistance properties of roller spare have been improved, combine firm composite ceramic coat with base material in the formation of carbon structural steel fabric guide roll surface, make that roller spare surface hardness reaches that HRC40 is above, bonding strength 30Mpa above, porosity is below 5%, coating wear resistance and excellent anti-corrosion performance, replacing the stainless steel rider spare of former integral body, and has remarkable economic efficiency.
For improving anchoring strength of coating, in the step b), the roughness after the roll body hair is handled is Sa3.。
The present invention also provides composite stainless steel ceramics powder component, mainly is made up of titanium oxide and aluminum oxide.
In order to improve anchoring strength of coating and to reduce coating porosity, the spray gun power of spraying equipment of the present invention is 60～80kw, and gas flow is 4～6m
3/ h, the outlet jet speed is 3000～5000m/s, can effectively ensure corrosion resistant, the wear resisting property of fabric guide roll.
Specific embodiment
One, Vehicle Processing general carbon steel pipe forms roll body.
Two, the pair roller external surface implement texturing handle to roughness be Sa3.
Three, roll body is carried out statical equilibrium test, alignment.
Four, plasma spraying is carried out in the pair roller surface, and spray material is the composite stainless steel ceramics powder of being made up of titanium oxide and aluminum oxide.Spray gun power is 60～80kw, and gas flow is 4～6m
3/ h, the outlet jet speed is 3000～5000m/s.
Five, polishing roll external surface.
