The European customer's product, high-efficiency ladle drainage sand, is ready for delivery at the factory of Anshan Justhigh New Material Development Co., Ltd. The contract is executed on EXW terms.
Customer requirements for products:
- No adhesion when passing steel
- 99% or better self-opening rate
Justhigh refractory determines the actual working conditions at the customer's site based on the requirements put forward by the customer. Our technical engineers verify the ladle working conditions with the customer.
As an important equipment in the metallurgical industry, the design and structural details of the ladle are very complex. To solve the refractory material solution for the ladle, we need to conduct the following research on the ladle:
| Basic information about ladle | Technical protocols |
| Ladle shell drawings | |
| Ladle amount | |
| Main smelting steel grades | |
| Loading steel amount and pouring amount (t) | |
| Turnover frequency (How many ladle online,how many furnace per 24h) | |
| Every parts' materials of ladle lining bricks (Whether contain carbon, aluminum or not) | |
| Ladle baking system and curve | |
| A guaranteed building model and its respective contents | |
| Requirements for the thickness of residual bricks lining various parts of the ladle | Ladle bottom impact zone |
| Ladle bottom non-impact zone | |
| Ladle wall part | |
| Slag line area | |
| Ladle mouth part | |
| Life span and residual thickness requirements of breathable bricks | |
| Life span and residual thickness requirements of nozzle seat bricks | |
| Basic equipment information | Transformer power |
| Electrode diameter | |
| Polar center radius | |
| Types and ingredients of slag covering agents | |
| Vacuum processing time | |
| Ultimate vacuum degree | |
| RH maximum circulation flow | |
| Average circulation velocity | |
| Working parameters (Number of units, number of flows, blank shape) | |
| Casting rate (m/s) | |
| Steel type superheat (℃) | |
| Refining basic information | Refining method and time |
| Argon blowing method (Single or double bottom blow) and strength | |
| Argon blowing time | |
| Slag volume size (defined as 150-200) | |
| Types and consumption of deoxidizers(m/min) | |
| Have slag removal measures or not | |
| Continuous casting or pouring completion time | |
| Representative smelting process flow | |
| Steel slag information | Converter slag blocking method |
| Ladle slag layer thickness(mm) | |
| Types and specifications of deoxidizers | |
| Slagging materials | |
| Steel slag color | |
| Steel slag powdering rate |
After understanding the actual needs of the customer and the on-site equipment conditions, Justhigh refractory technical engineers made a technical plan, conducted laboratory tests on the solution products, and produced appropriate samples for the customer to test. After the test, the customer was very satisfied with our plan and products, which met the customer's use requirements. The first batch of 60 tons of drainage sand products was ordered. As you can see in the picture now, this is the second batch of drainage sand products ordered by the customer. Our products have been recognized by European customer steel mills, so the customer placed an order again.
