Description
Technical field
The present invention relates to the welding method of a kind of ferrum-chromium-aluminum flat cold-rolled sheet when cold line continuous seepage, belong to welding method field.
Background technology
Ferrum-chromium-aluminum material is widely used in heating and heat-resistant component, wide market.But because under its room temperature, property is crisp, the cause of welding performance difference, is difficult to realize cold rolled continuous annealing pickling and produces.In recent years, Taiyuan Iron and Steel Co. drops into a large amount of manpower and materials, is intended to each difficulty of capturing the production of siderochrome aluminum steel continuous batch.One of them link be exactly ferrum-chromium-aluminum roll bending cold rolling after welding procedure when cold line continuous seepage.
Ferrum-chromium-aluminum material weldability is poor, ferrum-chromium-aluminum and self is almost without solderability.
Summary of the invention
The present invention aims to provide the welding method of a kind of ferrum-chromium-aluminum flat cold-rolled sheet when cold line continuous seepage, achieves the reliable welding of ferrum-chromium-aluminum material at cold rolled annealed pickling unit, thus realizes ferrum-chromium-aluminum thin plate and produce at the continuous batch of cold line.
The welding method of a kind of ferrum-chromium-aluminum flat cold-rolled sheet provided by the invention when cold line continuous seepage, comprises the following steps:
(1) between ferrum-chromium-aluminum sheet material and 304 leader tapes adopt along weldering, ferrum-chromium-aluminum sheet material upper, 304 leader tapes under;
(2) amount of lap of ferrum-chromium-aluminum sheet material and 304 leader tapes is 88-100mm;
(3) first step adopts the spot welding of machine automatic electric resistive:
Arrange machine solder joint two rows arranged side by side, two rows are in being staggered; Welding current is set as 30-35A;
The method to set up of machine solder joint is: to be arranged in parallel two row's solder joints at overlap, and the machine solder joint between two rows is 45 ° and is staggered; Described weld spacing is 20-30mm from the edge of band, and the distance of each solder joint vertical direction is 100 ~ 150mm, and the vertical range of horizontal direction is 50 ~ 75mm.
(4) second step adopts the artificial electric welding of common welding machine: employing diameter is the A402 stainless steel electrode of 3.2mm, and welding current is 80-90A;
Arrange artificial solder joint two rows arranged side by side, two rows are in being staggered; Each solder joint weld interval is 3 seconds, plays riveted joint act as standard with through welding solder joint;
The method to set up of artificial solder joint is: to be arranged in parallel two row's solder joints at overlap, and the machine solder joint between two rows is 45 ° and is staggered; Described weld spacing is 20-30mm from the edge of band, and the distance of each solder joint vertical direction is 100 ~ 150mm, and the vertical range of horizontal direction is 50 ~ 75mm.
(5) the 3rd steps adopt butt strips welding: choose long 250mm, wide 120mm, the 304 stainless steel butt strips of thick 1.2mm carry out on weld seam hand weldering overlap joint.
In above-mentioned steps, in described step (2), the amount of lap of ferrum-chromium-aluminum sheet material and 304 leader tapes is preferably 90mm.
Weld spacing must be greater than 20mm from the edge of ferrum-chromium-aluminum material, and hypotelorism can cause the cracking of edge of materials, reduces the reliability of welding greatly.
When weld seam crosses annealing furnace, speed-raising can be adopted, fall furnace temperature, subtract the risk that the method for tension force reduces weld cracking further, when weld seam is come out of the stove, recover normal process again.
Take common welding manner, the weld seam between ferrum-chromium-aluminum material and 304 leader tapes is easy to disconnect when producing, especially when crossing annealing furnace.It is that soldering test is carried out in breach that the present invention takes ferrum-chromium-aluminum and 304 to be the way of welding between stainless steel lead belt, by constantly groping, the a set of reliable welding method of final formation, is obviously better than common welding method by property, finally achieves ferrum-chromium-aluminum roll bending and produces in the continuous annealing of cold line.
The beneficial effect that the present invention brings:
(1) take ferrum-chromium-aluminum and 304 to be the method for welding between stainless steel lead belt, achieve ferrum-chromium-aluminum roll bending and produce in the continuous annealing of cold line;
(2) avoiding broken belt to producing the loss caused, having saved time and the manpower and materials of the loss of process broken belt simultaneously;
(3) solve the greateset risk of production siderochrome aluminum steel, finally achieve siderochrome aluminum steel and produce at the continuous batch of cold line.

In figure, 1 is ferrum-chromium-aluminum band, and 2 is 304 leader tapes, and 3 is weld zone, and 4 is butt strip, and 5 is machine solder joint, and 6 is artificial solder joint.
Detailed description of the invention
Further illustrate the present invention below by embodiment, but be not limited to following examples.
Embodiment:
The welding method of ferrum-chromium-aluminum flat cold-rolled sheet when cold line continuous seepage, comprises the following steps:
