Example Embodiment

[0042] Example 1-2:

[0043] Produce powdered materials, the chemical composition is shown in Table 1.

[0044] The continuous surfacing test was carried out on a continuous casting roll with a diameter of 180mm and a length of 1200mm. The continuous casting roll rotated 1.4 times per minute, the heating temperature was 500℃, and the water cooling temperature was set to 300℃. The anti-cracking performance is shown in Table 2.

[0045] Examples 1 and 2 used laser and arc heat sources for surfacing welding, respectively.

[0046] The samples were cut for high temperature wear and strength tests. The results are shown in Tables 3 and 4.

Example Embodiment

[0047] Example 3-4:

[0048] Make surfacing welding wire, the chemical composition is shown in Table 1.

[0049] The continuous surfacing test was carried out on a continuous casting roll with a diameter of 180mm and a length of 1200mm. The continuous casting roll rotated 1.4 times per minute, the heating temperature was 500℃, and the water cooling temperature was set to 300℃. The anti-cracking performance is shown in Table 2.

[0050] Examples 3 and 4 used submerged arc welding and gas shielded welding for surfacing respectively.

[0051] The samples were cut for high temperature wear and strength tests. The results are shown in Tables 3 and 4.

Example Embodiment

[0052] Example 5-6:

[0053] Make surfacing welding tape, the chemical composition is shown in Table 1.

[0054] The continuous surfacing test was carried out on a continuous casting roll with a diameter of 180mm and a length of 1200mm. The continuous casting roll rotated 1.4 times per minute, the heating temperature was 500℃, and the water cooling temperature was set to 300℃. The anti-cracking performance is shown in Table 2.

[0055] Examples 5 and 6 used submerged arc and electroslag surfacing methods respectively for surfacing.

[0056] The samples were cut for high temperature wear and strength tests. The results are shown in Tables 3 and 4.

Abstract

The invention relates to high-crack-resistance nickel-based surfacing alloy, comprising, by weight, 9-15% of Mo, 5-12% of Co, 5-12% of Cr, 0.3-1.2% of Al, 0.5-2.0% of Ti, 0.05-0.3% of Nb, and the balance of Ni and impurity elements, with (Al+Nb)</=Ti/2, W=1.5-4%, and Mo/6</=W</=Mo/3. The high-crack-resistance nickel-based surfacing alloy may be in powder, line, or sheet shape, and is applicable tosurfacing repairing of parts that bear high-temperature high-pressure service environments, such as continuous casting rollers.

Description

technical field [0001] The invention relates to a high-crack-resistant nickel-based surfacing alloy, which belongs to the field of welding technology, in particular to a nickel-based surfacing alloy for high-temperature and high-pressure service environments Background technique [0002] Many work rolls are used in the steel manufacturing process, such as for the work of compressing continuous casting billets in the mold, rolls for steel rolling, and various backup rolls and auxiliary rolls that do not come into direct contact with the steel. The continuous casting billet compression roller in the crystallizer needs to withstand the high temperature of up to 1400°C due to direct contact with the high temperature billet; at the same time, it also needs to withstand the strong spray from the cooling water, so the continuous casting billet compression roller will withstand high temperature and low temperature The cyclic heat action will easily produce thermal fatigue cracks on ...
