Abstract
The utility model relates to a high manganese steel integrate cast frog specific welding rod. The welding core of the welding rod adopts the H08 or H08A, and the percentages of the ingredient and the weight of the medicine coating are respectively that the marble contains 15%-30%, the titanium dioxide contains 15%-25%, the metal manganese contains 40%-80%, the ferromolybdenum contains 3%-7%, the metal chromium contains 1%-4%, and the wood powder contains 0.2%-0.6%. Besides, on the basis of the dispensation, the water glass of 25%-30% is added. When the welding rod provided by the utility model welds the high manganese steel integrate cast frog, the welding technological property is admirable, and compared with the repairing welding quality of the existing welding rod, the repairing welding quality of the utility model is improved.
Description
The utility model relates to the welding rod that is used to weld.
When potassium steel block cast frog uses, defectives such as wearing and tearing, crackle often occur on railway, need carry out repair welding.At present, when China carries out repair welding for potassium steel block cast frog defective, general adopt welding rods such as heap 256, heap 266, heap 276 and difficult to understand 102, difficult to understand 103, arc welding method welding by hand.With above welding rod potassium steel block cast frog is carried out repair welding, ubiquity welding procedure complexity is to welding operator specification requirement height.In the welding operation, the workman must constantly knock layer, and labour intensity is big, and fire check and cold crack often occur in welded joints.Abroad, have and adopt nickel-base welding rod that potassium steel block cast frog is carried out repair welding, adopt this welding rod, cracking resistance is higher, and processing performance is better, but because layer hardness is very low, behind the potassium steel block cast frog upper track behind the repair welding, very easily produce overlap, can not satisfy the specification requirement of potassium steel block cast frog actual operating conditions, simultaneously, the cost of nickel-base welding rod is high.More than all kinds of welding rod, its composition all belongs to high-carbon Gao Meng.
The purpose of this utility model is to overcome above-mentioned shortcoming, proposes a kind of potassium steel block cast frog welding rod special for special.
The welding rod that the utility model proposes (such as figure) be by core wire (1) and coating (2) formation, core wire (1) employing H08A or H08, the percentage by weight of coating is as follows:
Marble 15～30
Titanium dioxide 15～25
Manganese metal 40～80
Molybdenum-iron 3～7
Crome metal 1～4
Wood powder 0.2～0.6
On the basis of this prescription, add the waterglass that accounts for total amount 25%～30% again.
The components of welding electrode that the utility model proposes is the low-carbon high-manganese composition, and its weld seam layer is the dendritic crystalline tissue, and crystalline phase is unstable austenite.The utility model mainly is to utilize on the potassium steel block cast frog layer unstable austenite before impacting without train wheel, the layer yield strength is low, good toughness, the plasticity height prevents hot and cold crackle, after weld seam is impacted by train wheel, make the unstable austenite of surperficial one deck be transformed into martensite, thereby strengthen the hardness and the wearability of weld seam, satisfy the needs of railways train operation.
Potassium steel block cast frog welding rod special for special layer composition and percentage by weight are as follows:
C 0.15～0.50
Mn 15～30
Cr 0.5～3.0
Mo 0.5～3.0
The Si folder
S people
The P amount
The welding rod that the utility model proposes, its welding technological properties is splendid, only need utilize dc reverse connection that potassium steel block cast trouble is immersed in the tank and weld, do not occur weld crack fully, in welding, do not need layer is knocked, also do not need with the stainless steel electrode bottoming, and secondary striking performance is good.
Embodiment:
Utilize the utility model welding rod to repair 14 groups of potassium steel block cast frogs, be laid on certain railway section, carry out test running among a small circle, ruuning situation is good, and the analysis composition and the percentage by weight of its layer are as follows:
C 0.23
Mn 24.4
Cr 1.3
Mo 1.75
Si 0.08
S 0.008
P 0.034
Claims (1)
- Potassium steel block cast frog welding rod special for special is characterized in that the core wire (1) of welding rod adopts H08 or H08A, and core wire (1) external application is with coating (2), and the composition and the percentage by weight of coating are respectively:Marble 15～30Titanium dioxide 15～25Manganese metal 40～80Molybdenum-iron 3～7Crome metal 1～4Wood powder 0.2～0.6On the basis of said ratio, add the waterglass that accounts for gross weight 25～30%.
