Abstract

The present invention relates to flux-cored wire fields, especially corrosion resistant type flux-cored wire.The flux-cored wire all the components mass percent is as follows: rutile 30 ~ 42%, quartz 4 ~ 7%, magnesia 2 ~ 5%, potassium fluoride 3 ~ 6%, nickel powder 11 ~ 14%, crome metal 5 ~ 8%, mid-carbon fe-mn 6 ~ 9%, niobium powder 8 ~ 11%, molybdenum powder 1 ~ 5%, iron powder 4 ~ 7%, and surplus is hafnium powder.The invention is more more corrosion-resistant than conventional flux-cored wire.

Description

Corrosion resistant type flux-cored wire

Technical field

The present invention relates to flux-cored wire fields, especially corrosion resistant type flux-cored wire.

Background technique

Flux-cored wire is a kind of novel welding material, has the advantage of the various aspects such as high benefit, low cost, high quality, It is adjustable that it inherits components of welding electrode, but overcome welding rod cannot continuous, automatic welding the shortcomings that, also have high-efficient, appearance of weld The series of advantages such as fairing beauty.Flux-cored wire has following features: high production efficiency, constituent adjustment compared with solid core welding wire Flexibly, energy saving low pollution.Such as in shipbuilding industry, flux-cored wire has replaced stick electrode and solid welding wire, and it is maximum to become consumption Welding material, and by its welding have high intensity, high tenacity, cracking resistance, anti-stomata excellent properties, have become and make Ship, large bridge, ocean platform etc. build most important wlding.But existing medicinal powder formulation ratio is undesirable, and flux-cored wire is not It is corrosion-resistant.

Summary of the invention

In order to overcome not corrosion resistant enough the deficiency of existing flux-cored wire, the present invention provides corrosion resistant type flux-cored wires.

The technical solution adopted by the present invention to solve the technical problems is: a kind of corrosion resistant type flux-cored wire, all the components Mass percent is as follows: rutile 30 ~ 42%, quartz 4 ~ 7%, magnesia 2 ~ 5%, potassium fluoride 3 ~ 6%, nickel powder 11 ~ 14%, and crome metal 5 ~ 8%, mid-carbon fe-mn 6 ~ 9%, niobium powder 8 ~ 11%, molybdenum powder 1 ~ 5%, iron powder 4 ~ 7%, surplus is hafnium powder.

Specifically, the rutile 35 ~ 42%, quartz 4 ~ 6%, magnesia 2 ~ 4%, potassium fluoride 3 ~ 5%, nickel powder 11 ~ 13%, metal Chromium 5 ~ 7%, mid-carbon fe-mn 6 ~ 8%, niobium powder 8 ~ 10%, molybdenum powder 1 ~ 4%, iron powder 4 ~ 6%, surplus are hafnium powder.

Specifically, the rutile 40%, quartz 5%, magnesia 3%, potassium fluoride 4%, nickel powder 12%, crome metal 6%, medium carbon manganese Iron 7%, niobium powder 9%, molybdenum powder 3%, iron powder 5%, surplus are hafnium powder.

The invention has the advantages that the invention is more more corrosion-resistant than conventional flux-cored wire.
