Description
Technical field:
The invention belongs to a kind of wlding material that helps, particularly a kind of novel welding material.
Background technology:
Knot 422 is welding rods of titanium-calcium type coating, be the leading products of China each producer of welding rod industry, and electrode coating coating main component is made up of titanium dioxide, silicate, carbonate etc.In recent years because the rise of the prices of raw and semifnished materials, particularly be rich in the rise of carbon dioxide material price, the welding rod product cost risen greatly, therefore, successively many producers all replacing with ilmenite or partly replacing rutile and titanium white production welding rod, obtain than remarkable economic efficiency in the industry.But because the adding of a large amount of reduced ilmenites reduces and maybe need not slide plasticity titanium dioxide preferably, it is unfavorable that the welding rod extrusion is brought, the mobile variation of coating during as the welding rod extrusion, coating easily harden the heating shaping have some setbacks, the welding rod rough surface of extrusion, wool top more easily takes place.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, and a kind of novel welding material is provided, and this material can improve the extrusion of coating paint, improves the welding rod presentation quality, and can reduce the production cost of welding rod greatly.
Technical scheme of the present invention is: a kind of novel welding material is characterized in that: it forms formation and parts by weight are respectively: sepiolite 2-6 part, reduced ilmenite 20-38 part, rutile 5-10 part, white clay 10-12 part, mica 2-6 part, marble 8-12 part, mid-carbon fe-mn 9-12 part, feldspar 10-12 part, other composition 1-2 part.
Can add 2 parts of titanium dioxides in the above-mentioned constituent.
The optimum weight umber that above-mentioned composition constitutes is 5 parts of sepiolites, 37 parts of reduced ilmenites, 10 parts of rutile, 12 parts of white claies, 5 parts on mica, 12 parts in marble, 9 parts of mid-carbon fe-mns, 10 parts of feldspars.
The optimum weight umber that above-mentioned composition constitutes is 3 parts of sepiolites, 37 parts of reduced ilmenites, 8 parts of rutile, 12 parts of white claies, 5 parts on mica, 12 parts in marble, 9 parts of mid-carbon fe-mns, 10 parts of feldspars, 2 parts of titanium white parts.
Above-mentioned other composition is the mixture of starch, microcrystalline cellulose, wood powder, bamboo powder.
Sepiolite among the present invention belongs to palygorskite-sepiolite clay mineral family, also cries silicon U.S. breeze, its molecular structural formula Mg
8[Si
12O
30] (OH)
4(OH

2O, molecular weight are 1292, and the actual sepiolite main chemical compositions of using is Mgo 〉=20%, and Sio 〉=56% contains a spot of AI
2O
3, Feo etc., contain S.P all≤0.030%; Granularity is 100% mistake, 80 orders, and 80% crosses 150 orders, and loose specific weight is 0.71 gram/cm
3, it is thin to have a particle, and light weight is compared with titanium dioxide, the white clay of tradition usefulness, and the sliding property of feel is identical with titanium dioxide, and is better than white clay; Mobile all better than titanium dioxide, white clay; Stronger caking property and plasticity are arranged after the suction.Sepiolite can improve greatly coating visco-plasticity, improve the extrusion performance, help compression moulding, improve coating intensity, improve presentation quality, therefore sepiolite can replace titanium dioxide fully, because the unit price of sepiolite is 415 yuan/ton, can reduce the production cost of welding rod greatly again.
With regard to the welding technological properties influence of sepiolite to welding rod, sepiolite is to welding rod extrusion Effect on Performance below, and the influence of sepiolite butt welded seam Mechanical Property of Metal, chemical composition is analyzed:
1. sepiolite influences the welding technological properties of welding rod:
Because sepiolite has than the better sliding property of titanium dioxide, white clay, flowability and bonding, think that promptly available volume sepiolite replaces titanium dioxide and a part of white clay, but find through two-wheeled test back, the sepiolite consumption more for a long time, though coating has advantages such as better sliding property, extrusion flowability and caking property, but welding the time cause splash bigger, slag is rare excessively, slag fluidity is bad, wayward, slag covers inhomogeneous, appearance of weld is coarse, and full position operation performance is bad, and welding technological properties is worsened.In order to inquire into sepiolite to tying the influence of 422 usabilities of electrode energy, so that find out the best scope of application, we compare test with four levels of sepiolite consumption work done in the manner of a certain author (3%, 5%, 7%, 9%).(seeing Table 1)
Result from table 1 test, sepiolite should not adopt in this type of prescription in a large number, after surpassing 5%, will cause consumption the welding molten slag thinning, the molten slag flowability is wayward, it is inhomogeneous that weld metal is covered, splash to increase to wait and worsen welding technological properties, and consumption is tending towards normal less than 5% o'clock welding technological properties.Table 1
It is big to splash, and slag is rare, and mobile bad, slag covers inhomogeneous, and moulding is bad.It is big slightly to splash, and slag fluidity can cover by slag, and moulding is good.It is general to splash, and slag fluidity is good, and operation is light, and slag covers evenly, and moulding is attractive in appearance.</entry></row></tbody></tgroup></table></tables>
2. sepiolite is to welding rod extrusion Effect on Performance
According to the situation of above-mentioned test, we are only with regard to 3
#, 4
#Prescription carries out the test of spiral extrusion with the original formulation that does not add sepiolite.(subordinate list 2) adds the paint formulation of sepiolite from the extrusion result of the test of table 2, and the extrusion performance makes moderate progress, and has improved electrode coating intensity, makes the coating any surface finish, has reduced the waster rate.
Table 2

3. the influence of sepiolite butt welded seam metal physicochemical property
On the basis of above-mentioned discussion, we have only done 3
#, 4
#With the weld metal mechanical performance of original formulation welding rod and the analysis of experiments of chemical composition thereof, it the results are shown in Table 3, table 4.From table 3, the contrast situation of table 4 sees that the physicochemical property that adds an amount of sepiolite butt welded seam metal can not cause adverse effect, the intensity of its weld metal is moderate, plasticity, toughness index be also than higher, and it is also relatively more an amount of that the composition of weld metal chemistry contains manganese, silicon amount, and sulfur-bearing, phosphorus amount are lower.
