Example Embodiment

[0026] The preparation method of the above 42 kg titanium carbon steel electrode includes the following steps: take various materials according to the stated ratio and mix them evenly, adopt spiral electrode production equipment, use modulus 2.3-2.8, potassium sodium ratio 2.5-4 : 1. Potassium-sodium mixed water glass with a concentration of 37-40° Baume is used as a binder. The addition amount is 18-25% of the weight of the mixed powder. After stirring, use the spiral electrode production equipment to evenly coat the different diameters. On the welding core; after grinding the clamping end and the arc starting end, use a welding rod drying furnace to dry at a low temperature of 45-90℃, a medium temperature of 90-130℃, and a high temperature of 130-180℃ to prepare reduced titanium iron Mine type 42 kg titanium type carbon steel acid electrode.

Abstract

The invention discloses a 42 kg-level titania type carbon steel covered electrode and a preparation method thereof. The 42 kg-level titania type carbon steel covered electrode comprises a core wire; the formula of a covered electrode coating comprises the following components in percentage by weight: 47-58% of reduced ilmenite, 0-4% of rutile, 6.5-11.5% of potassium feldspar, 3.5-6% of lime mud, 3.5-6% of illite, 2-6.3% of mica, 2-4.6% of fine mica, 0-6.3% of wollastonite, 5-7% of mid-carbon ferromanganese, 5-11.5% of marble and 1-4% of organic matters. The covered electrode can be prepared through a universal manufacturing technology of screw-type or hydraulic-type production equipment in the industry without special requirements, has excellent welding technological properties, mechanical properties and production press coating performance, and can be in AC/DC use.

Description

Technical field [0001] The invention relates to a carbon steel electrode and a preparation method thereof, in particular to a reduced ilmenite type 42 kg titanium carbon steel acid electrode and a preparation method thereof, belonging to the field of welding materials. Background technique [0002] Ordinary 42kg grade titanium carbon steel acid electrode is one of the most widely used welding materials in our country, accounting for more than 70% of manual welding electrode consumption. The electrode coating of this electrode contains a large amount of TiO 2 , Due to the reduction of TiO in ilmenite 2 The content is low, if the reduced ilmenite is completely used to obtain the TiO in the electrode coating 2 , It will inevitably affect the addition of other materials, cause the production pressure coating performance of the electrode to deteriorate, and at the same time deteriorate the welding process performance and mechanical properties of the electrode. Therefore, usually the Ti...
