产品描述

符合标准:

GB/T 17854-1999 F410-H1Cr13

 

说明:WD-8015是氟碱型烧结焊剂,碱度约为1.8(BIIW),为球形颗粒,粒度为10-60目。与相应药芯、高Cr-Ni型实芯焊丝匹配,用于金属表面堆焊。其抗裂纹和焊接工艺性能优良,特别是脱渣性优异。适于各种较小直径轧辊的焊接。配合药芯焊丝进行轧辊堆焊,合金元素烧损少,可保证其堆焊表面的硬度及耐磨性。

 

用途:可用于堆焊热轧工作辊、支撑辊、开坯辊、校直辊、助卷辊和连铸辊等。

注意事项:

1、焊剂如果受潮,在使用前须经300~350℃烘焙2小时。

2、焊接处须清除铁锈、油污、水分等杂质。

3、焊前预热300~400℃。

 

WD-8015 Agglomerated Flux For S.A. Welding
 
Standards: GB/T 17854  F410-H1Cr13
 
Introduction
 
WD-8015 is an agglomerated fluoride-basic type flux with a basicity index of BIIW 1.8. The flux is  spherical granular, grain size is from 10 to 60 mesh. It matches the corresponding flux core and high Cr-Ni solid, for metal surfacing. It has excellent crack resistance and welding technology. Slag detachability is good.
 
Applications
 
Hard surfacing of rollers for hot working, supporting, pressure, straightening and continuous casting.

Notice:
 
1. Flux should be redried at 300~350°C for 2 hours.
2. All dust, oil and rust should be removed.
3. Preheating at 300~400°C before welding.
