Rongxin Electrode Paste Science
Common concerns of electrode paste customers generally include issues such as: electrode paste breakage; electrode paste spalling; high electrode paste consumption; electrode paste caking; electrode paste technical support; electrode paste after-sales service; electrode paste quality stability, etc. What are the causes of these problems and how to address them? Based on their 30 years of production experience and accumulated knowledge in electrode paste production and usage, Rongxin Electrode Paste engineers have developed systematic handling plans and established comprehensive solutions for the causes and resolutions of each problem.
Rongxin Electrode Paste was established in 1992 and now has 33 years of history. Over these 33 years, Rongxin Electrode Paste has accumulated a large number of customers, both domestic and international, with markets spanning Asia, Southeast Asia, Europe, America, Oceania, and Africa. Whether old or new customers, what often receives the most attention is the occurrence of electrode breakage during the use of electrode paste. Electrode breakage often affects the completion of production tasks and requires furnace shutdown for repair, causing significant economic losses for customers. It also involves attributing accident responsibility, which can often lead to conflicts between suppliers and customers, sometimes resulting in customers changing suppliers or suppliers cutting off supply. Therefore, electrode breakage must be taken seriously. Rongxin Electrode Paste has convinced numerous customers with its professional and responsible attitude. Below is an overview analysis of the causes of electrode breakage.
I Factors Related to Electrode Paste Production Index Control
1. Excessive Ash Content: Leads to reduced electrode strength, easily causing breakage.
2. Abnormal Volatile Matter Content: Excessively high or low volatile matter affects the sintering quality of the electrode, leading to insufficient strength or delamination.
3. Inadequate Mixing and Kneading: Improper mixing of electrode paste ingredients or insufficient sintering, forming internal defects.
II Factors Related to Submerged Arc Furnace Production Process
1.Excessively Long Furnace Shutdown: Failure to take effective protective measures leads to electrode oxidation, reducing strength.
2.Excessive Load Variations: Sudden power outages or drastic load changes cause thermal stress concentration.
3.Electrode Being Too Long or Too Short: Excessive self-weight or insufficient sintering makes the electrode prone to breakage from gas flow impact or mechanical stress.
III Factors Related to Submerged Arc Furnace Operation
1.Inadequate Protective Measures: Failure to cover the electrode with a protective layer during shutdown allows dust to enter the electrode casing, forming an insulating layer.
2.Improper Electrode Raising/Lowering Operation: Improper securing or excessive lowering frequency leads to mechanical breakage.
Therefore, Rongxin Electrode Paste engineers recommend analyzing based on the specific causes and taking corresponding measures: optimizing the electrode paste formulation, enhancing shutdown protection, controlling the rate of load changes, standardizing operational procedures, etc., to reduce the risk of breakage.
