Weihua Overhead Cranes Assists Operation of 100000T Graphite Electrode Project

At 10:30 am of December 21, the opening ceremony of a 100,000-ton ultra-high-power graphite electrode project was successfully held. Many city leaders and Weihua Group President Yu Youfei attended the event. There are more than 300 people including city leaders, suppliers, people of design and construction unit participated in the activity.



Graphite electrodes are consumables for smelting iron and steel. As we know, the main characteristics of graphite electrode manufacturing are "dirty, tired, and dumb". As an important raw material for steel smelting, and manufacturers have different size requirements for the graphite electrode, and there is no standardized string and transfer equipment. Most of time, people use primitive manual methods. For example, small-diameter graphite electrodes of each furnace requires more than 20-time grouping and transfers, which is time-consuming and labor-intensive, and the efficiency is extremely low.



To this end, Weihua provided several multi-functional intelligent bridge cranes for this project and provide reasonable solution for the successful operation of the project.



The overhead cranes for graphite electrode handling can realize full handling of graphite electrodes such as storage, grouping, film winding, strings, automatic switching of single and double rows, loading and unloading of single or double rows of multi-specification graphite electrodes. And lifting the furnace cover. It turns the complexity into simplicity. Weihua smart overhead cranes improve the product quality of graphite electrodes and truly realizes the efficient production of graphite electrodes.

Weihua 300 Tons Overhead Crane for Steel Foundry Plant

 On May 18th, the Capacity Upgrade Project of an Iron and Steel Company blast furnace was successfully ignited. The project entered the stage of full-line production, opening a new chapter in the optimization of the layout, transformation and upgrading of the iron and steel industry in Henan Province.

 

 

Weihua made several capacity 300t overhead cranes for its steel foundry plant. These cranes are with four-girder four-track structure, which is for the task of foundry process transfer, converter charging, refining and molten steel receiving.

 

 

Features of Weihua Foundry Cranes

 

1. Overall processing

The overall annealing and overall processing of the main hoisting frame ensure the installation accuracy of gears, bearings, motors, brakes, etc., with low noise, smoothness and no impact; the overall processing of the bridge frame ensures product wheel line accuracy and more stable operation.

 

2. Life service life

The detachable plate hook lining makes longer service life of the spreader.

 

3. Dual transformer mode

The transformer adopts the dual transformer mode of power transformer + auxiliary transformer.

 

 

4. Double Regulate

The whole crane is equipped with a backup redundant system. When a certain mechanism fails, the backup system can be quickly switched to ensure that the equipment does not stop and operates safely for 24 hours.

 

5. Safety projection warning

The system is equipped with a safety projection warning device, which can effectively remind ground personnel to perform safe operations when driving.

 

6. Safety management system

Analyze the crane's operating status, working hours and usage times of wearing parts to facilitate equipment maintenance.

 

 

7. Multiple security protection

The boarding gate is equipped with a permanent magnet door switch, and a deceleration stop alarm system is designed in the corresponding operating mechanism.

 

8. Compact structure layout

The control system has a compact structure layout, which satisfies the application functions of short-span cranes.
