PRODUCT DESCRIPTION

NAME: HD Grate Electrode

MODEL: 100MM

grate electrodes Supplier:Shijiazhuang huanan carbon factory

Introduction

The grate electrode is mainly made of petroleum coke and needle coke, and the coal aslt is used as a binder. It is made by calcination, distributing, kneading, forming, roasting, gratization and machining. It's a conductor which release electric energy in the form of electric arc in the electric arc furnace heats and melts the material. the charge can be divided into a regular power grate electrode, a high power grate electrode and an ultra high power grate electrode according to its quality index. The main raw material for grate electrode production is petroleum coke. The regular power grate electrode can be added with a small amount of pitch coke. The sulfur content of petroleum coke and pitch coke cannot exceed 0.5%. Needle coke is also required for the production of high power or ultra high power grate electrodes.

China grate electrodes Advantage:

The advantage of grate electrode is that it is easy to process, the electricity discharge processing rate is high, and the grate loss is small.

Production characteristics

The production period is long. The production period of regular power grate electrodes is about 45 days, the production period of ultra high power grate electrodes is more than 70 days, and the production period of grate electrode joints (nipples) requiring multiple impregnation is more longer.

Application

Mainly used in electric arc steelmaking furnaces, refining furnaces, industrial silicon furnaces, yellow srus furnaces, electric resistance furnaces, etc., as conductive usage. The grate electrode blank is also used to process a variety of shaped grate products such as enamel, mold, boat and heating pan>
