Abstract
The invention relates to a manufacturing method for a welding electrode and the welding electrode manufactured by using the same. The method is obtained by improving the existing manufacturing method for the welding electrode and is characterized in that yttrium, yttrium oxide, calcium silicon alloy and iceland spar are added in the existing mixed welding flux comprising manganese, atomized iron powder, ferrotitanium, red copper powder, sepiolite, while mud, titanium dioxide, marble, fluorite, quartz, low-silicon iron, nickel powder, sodium carbonate and high-modulus sodium silicate. The welding flux in the manufacturing method has the advantages of being reasonable in formula and matching and good in technical stability. The welding electrode manufactured by using the method has generality that the electrode can be used for welding different black metals, can be used for conducting mutual welding, is firm in welding and good in reliability, can be used for conducting welding under low temperature, resists thermal expansion and cold contraction and is low in welding production toxicity (10 times lower than the national standard), huge in economical benefit and the like.
Description
Affiliated technical field
The present invention relates to a kind of preparation method of welding rod and the welding rod made from the method thereof.
Background technology
It is reported that at present, although it is of a great variety to be used for the welding rod of welding, ubiquity has the monistic problem of use, namely different ferrous metal must select different welding rods to weld.All can not weld under the condition of low temperature in addition, and can produce the dense smoke of high poison in the process of welding, especially be unsuitable for the operation in the small space, it not only has harm but also affects operating efficiency human body.Studying carefully its main cause is prescription and the proportioning existing problems of its welding agent in the process of making welding rod.In order to solve this difficult problem, many people are being devoted to the work of this respect, do not see also that so far desirable welding rod comes out.For this reason, we have also done a large amount of steadfast and assiduous careful R﹠D works, and have obtained gratifying significant effect.
Summary of the invention
The present invention aims to provide the preparation method of a kind of welding agent prescription and reasonable mixture ratio, a kind of welding rod that technical stability is good and has the versatility that can weld different ferrous metal and can weld mutually with what the method was made, the firm welding unfailing performance is good, can under the condition of low temperature, weld, the heat resistanceheat resistant shrinkage of expanding, welding produces low toxicity, the welding rod that economic benefit is huge.
The technical scheme that the present invention solves its technical problem is: with the existing welding wire that pulls out; Cut welding wire; Make the mixing welding agent with manganese metal, atomized iron powder, ferrotianium, red copper powder, sepiolite, white clay, titanium dioxide, calcite and fluorite, quartz, low-silicon iron, nickel powder, soda ash, high mould waterglass; To mix welding agent and press group; The mixing welding agent of the group of being pressed into and welding wire dropped in the welding rod hydraulic forming machine carry out extrusion modling; The welding rod of extrusion modling is delivered to top and end grinding machine carry out bistrique mill tail; Welding rod after bistrique grinds tail is carried out natural drying under normal temperature condition; Welding rod after natural drying sent into carry out high temperature drying in the high temperature kiln; Stopped heating carries out the nature cooling after the high temperature drying; To take out through the welding rod of naturally cooling the method for packing making welding rod is improved.For the versatility that welding rod had to weld different ferrous metal and can weld mutually, the firm welding unfailing performance is good, can under the condition of low temperature, weld, the heat resistanceheat resistant shrinkage of expanding, welding produces low toxicity increase in mixing welding agent yttrium and yittrium oxide, calcium-silicon, ice state stone, its manganese metal, atomized iron powder, ferrotianium, the red copper powder, sepiolite, white clay, titanium dioxide, marble, fluorite, quartzy, low-silicon iron, nickel powder, soda ash, high mould waterglass, yttrium and yittrium oxide, calcium-silicon, the weight ratio of ice state stone is: 3: 2: 10.5: 1: 1.6: 1.6: 2: 45: 20: 6: 4: 4: 0.8: 15～20: 0.1: 0.5: 0.1.
For its high temperature drying of quality that guarantees product is to rise to 120 ℃ by normal temperature, constant temperature 25～40 minutes; Then be warming up to 280 ℃ by 120 ℃, constant temperature 25～40 minutes; And then be warming up to gradually 430 ℃ by 280 ℃; Stopped heating after being warming up to 430 ℃.
The invention has the beneficial effects as follows, because by manganese metal, atomized iron powder, ferrotianium, the red copper powder, sepiolite, white clay, titanium dioxide, marble, fluorite, quartzy, low-silicon iron, nickel powder, soda ash, yttrium and yittrium oxide have been increased in the mixing welding agent that high mould waterglass consists of, calcium-silicon, ice state stone, and filtered out its manganese metal, atomized iron powder, ferrotianium, the red copper powder, sepiolite, white clay, titanium dioxide, marble, fluorite, quartzy, low-silicon iron, nickel powder, soda ash, high mould waterglass, yttrium and yittrium oxide, calcium-silicon, the weight ratio of ice state stone is: 3: 2: 10.5: 1: 1.6: 1.6: 2: 45: 20: 6: 4: 4: 0.8: 15～20: 0.1: 0.5: 0.1 optimum weight ratio, therefore, make the welding agent in the preparation method have prescription and reasonable mixture ratio, technical stability is good, and have the versatility that to weld different ferrous metal and can weld mutually with the welding rod that the method is made, the firm welding unfailing performance is good, can under the condition of low temperature, weld, the heat resistanceheat resistant shrinkage of expanding, the advantages such as welding produces low toxicity (than low 10 times of national standard), and economic benefit is huge.
