Quality control measures in processing of graphite electrodes production

Here are the main points of quality control measures and the purpose about the measures

First Quality Control Measures Point

Measure Of Procure Quality Raw Materials

Purchasing Daqing Refining & Chemical and Fushun Refining & Chemical Company 1 # A grade quality petroleum coke, calciner with calcination at the temperatures above 1350 ℃. This petroleum coke is the best material for the production of high-grade electrodes, and the basis for the production of high quality products.

Purpose Of The Measure about Procure Quality Raw Materials

Products’ physical and chemical indicators better than national standards.

Second Quality Control Measures Point

Measure Of Leading Computer Batching System

Using the most advanced microelectronic batching system for the production of high-quality electrode products, it increased the effective protection. To ensure that the internal structure of the electrode homogeneity and stability are guaranteed.

Purpose Of The Measure about Leading Computer Batching System

Become more homogeneous and ingredients more accurate.

Third Quality Control Measures Point

Measure Of 3500 tons extrusion molding machine With vacuum,

synchronous cutting advanced process

One of the few has 35MN extrusion molding machine Carbon Plant, Using 35MN extrusion molding machine production of electrode compared with other similar products, Indicators are better than the national standard, especially vacuum, synchronous technology make sure high bulk density and the bending strength strong. Low consumption, more energy efficient.

Purpose Of The Measure about 3500 tons extrusion molding machine With vacuum,

synchronous cutting advanced process

Greater bulk density and flexural strength, structure more perfect.

Fourth Quality Control Measures Point

Measure Of Automatic temperature baking system

To improve the first step quality of processing, we changed the traditional gas heating into natural gas heating, and in cooperation with CIMA Technology Co., Ltd. introduced automatic optimization of robust multivariable predictive control system, so that the internal structure of carbon products become more homogeneous and high finished rate.

Purpose Of The Measure about Automatic temperature baking system

Baking curve more perfect and products become more homogeneous.

Fifth Quality Control Measures Point

Measure Of 2000KVA within string graphite furnace

The earliest using Graphite heat series furnace, earlier in 2000 overcome the high-power, ultra-high-power graphite electrodes inside string of successful experiments and become a model of domestic counterparts, learn from the advanced experience of foreign countries, technological innovation, expansion of large-scale heat 20000KVA concatenation graphitization furnace equipment, guaranteed further high quality, and homogenized product.

Purpose Of The Measure about 2000KVA within string graphite furnace

The higher the degree of graphitization, the lower resistivity.

Sixth Quality Control Measures Point

Measure Of Precision CNC machining lines

In year 2003 introduction of precision CNC machining line machine From Jiangsu Taixing Chen’guang High-Tech Development Co., Ltd., Created excellent conditions for producing high-precision electrode, completely overcome the using risk and ensure the safety of users.

Purpose Of The Measure about Precision CNC machining lines

Precision machining, nipple and electrode combination more perfect, to ensure the safety of users, and reduce consumption.
